a semi-truck carrying millions of honey bees overturned on the right shoulder of southbound Interstate 435 near the Interstate 35 intersection in the Northland.

Updated 1 hr 46 mins ago
KANSAS CITY, Mo. -- Drivers along an interstate north of Kansas City were told to be on the lookout for an unusual traffic hazard after a semi-trailer truck loaded with honeybees overturned.

The Missouri Department of Transportation said the accident occurred Friday on Interstate 435. No serious injuries were reported.

The Transportation Department initially said the truck was carrying about 40,000 bees.

But the Kansas City Star reports bee experts said between 8 million and 11 million bees were in the truck. Some of the bees flew away from the accident scene.

Matt Winstead, of Midwest Bee Removal, says hives typically contain about 40,000 bees. The owner of the hives, Brian Buoye said about 408 hives were being transported.

The Missouri Department of Transportation reported shortly after noon Friday that a semi-truck carrying millions of honey bees had overturned on the right shoulder of southbound Interstate 435 near the Interstate 35 intersection in the Northland.

An emergency response team from the department, as well as Kansas City police, responded to the scene and called local bee companies to help control and gather the insects. Authorities said at least some of the bees had flown away from the semi.

MoDOT originally reported that the truck had been carrying 40,000 bees. A local bee expert called to the scene to help, as well as the owner of the bees, said the number was in the millions.

Hives typically contain 40,000 bees, said Matt Winstead of Midwest Bee Removal.

Owner Brian Buoye said that 408 hives were being transported. Both men estimated the number of transported bees to be between 8 million and 11 million.

MoDOT officials said they had been initially informed that the truck contained 40,000 bees and could not immediately clarify the number of bees being transported. The truck was reportedly traveling from North Dakota to Tampa, Fla.

The semi-truck was off the road and not directly affecting traffic, police said, though several tow trucks on the highway’s right shoulder were utilized to clear the scene.

“#Beesafe,” MoDOT tweeted, suggesting that drivers use caution in the area.

Louisiana flooding leaves 100,000 insured vehicles damaged

Louisiana flooding leaves 100,000 insured vehicles damaged: NICB

September 1, 2016 by Canadian Underwriter

The August downpours that dumped more than 30 inches of rain in two days on parts on Louisiana have left as many as 100,000 insured cars and trucks damaged, the National Insurance Crime Bureau (NICB) in the United States said on Thursday.

According to the Louisiana Office of Motor Vehicles, “the numbers are much higher than originally expected,” NICB said in a press release. While claims reporting and vehicle recovery efforts were initially slowed by the large scale flooding, they are now in full swing, the bureau added.

“The number of uninsured vehicles that were flood damaged may be even more than the number of insured vehicles since many owners choose to drop their policy’s comprehensive coverage as the vehicle ages,” NICB warned. “Flooded vehicles that did not have insurance coverage are a major concern as they are frequently cleaned up to hide the damage and then sold to unsuspecting consumers with no indication of a problem.”

Based on the extensive vehicle losses following Hurricane Katrina in 2005, Louisiana enacted strong measures to help protect unsuspecting consumers from buying a flood-damaged vehicle, NICB reported. Once an insured vehicle has been determined by the insurer to have been flood-damaged, it is towed to an auction facility and processed with a new title that indicates it has been water-damaged.

In Louisiana, during an emergency like the recent flooding, the severity of flood water damage may require a Certificate of Destruction. In that case, the vehicle has to be crushed, or sold to a company that will dismantle it for parts and destroy what remains. The vehicle identification number (VIN) is entered into the state’s records, NICB’s VINCheckSM, and the National Motor Vehicle Title Information System (NMVTIS) so that consumers can check a vehicle history before purchasing a used car or truck.

“It’s buyer beware,” said the state’s Commissioner of Motor Vehicles, Karen St. Germaine, who warned those in the market for a used car both in state and across the country to do their homework before putting any money on the line. For example, buyers should:

Look for water stains, mildew, sand or silt under the vehicle’s carpets, floor mats and dashboard, and in the wheel well where the spare is stored. Look for fogging inside the headlights and taillights;
Do a smell test – a heavy aroma of cleaners and disinfectants is a sign that someone is trying to mask an mould or odour problem;
Check a trusted database service, such as the NICB’s free VINCheckSM database and the Louisiana Office of Motor Vehicle’s site;
Have a trusted mechanic inspect the car’s mechanical and electrical components and systems that contain fluids for water contamination.

The flooding in Louisiana that began on Aug. 12 has been called “one of the most significant U.S. natural disasters, let alone flood events, since Superstorm Sandy” in 2012 by Risk Management Solutions, Inc. (RMS).

According to RMS, heavy rainfall caused riverine flooding across Louisiana, with large parts of southeastern Louisiana receiving more than 10 inches of rain over a 48-hour period and some areas receiving as much as 31 inches. RMS has estimated that the number of properties affected by the flooding ranges from 40,000 to 60,000.

Flooding has been particularly severe in the parishes of Livingston (~39,000 homes flooded), Ascension (~15,000 homes flooded), East Baton Rouge and Tangipahoa.

On Aug. 14, Aon Benfield’s Impacting Forecasting estimated that the recent flooding across parts of Louisiana and southern Mississippi could approach or possibly exceed US$1.5 billion in economic damage.

Headquartered in Des Plaines, Ill., the NICB is a not-for-profit organization exclusively dedicated to preventing, detecting and defeating insurance fraud and vehicle theft through data analytics, investigations, training, legislative advocacy and public awareness, the release said.

The NICB is supported by more than 1,100 property and casualty insurance companies and self-insured organizations. NICB member companies wrote over US$413 billion in insurance premiums in 2015, or more than 79% of the nation’s P&C insurance (including more than 94 percent (US$187 billion) of the nation’s personal auto insurance.

The City of Bethany is suing Rockwell Automation and Gulfstream Aerospace after a “plume” of hazardous chemicals contaminated public water supplies and forced the city to shut down a pair of municipal water wells.

SEPTEMBER 2, 2016

The City of Bethany, OK is suing a pair of aerospace companies after a “plume” of hazardous chemicals migrating from an airport manufacturing plant contaminated public water supplies and forced the city to shut down a pair of municipal water wells.

In the federal lawsuit, filed Aug. 31 in U.S. District Court for the Western District of Oklahoma, the city claims Rockwell Automation and Gulfstream Aerospace owned and operated an aircraft manufacturing facility at Wiley Post Airport contaminated with toxic solvents and degreasers containing trichloroethene and tetrachloroethene, which have been detected in municipal wells at levels exceeding federal limits.

Bethany was forced to shut down two wells. Attorneys say the chemicals are “threatening to contaminate” the city’s supply of public drinking water, according to the complaint. Bethany says Milwaukee-based Rockwell and Savannah, Ga.-based Gulfstream knew about the contamination in 2008, but didn’t notify the city until 2012. The city is suing the companies to recover costs for treating, testing and monitoring its wells and finding a clean replacement water source for its customers.

The manufacturing plant was built in the 1950s and operated by Rockwell until the ‘80s, when it was taken over by Gulfstream. The plant closed its doors in 2002. While testing by Bethany and the Oklahoma Department of Environmental Quality has shown pollution exceeding limits set by the U.S. Environmental Protection Agency “in some areas, both Gulfstream and Rockwell deny this,” The Oklahoman’s Brianna Bailey reports:

“To date, the consistent testing of the City of Bethany’s water supply has not shown evidence of any contaminants associated with the operations at the former manufacturing facility,” the companies said in a statement. “The ODEQ’s periodic testing of Bethany’s groundwater has consistently demonstrated that the groundwater complies with all federal clean water standards.”

Daikin America agreed to a $5 million settlement to a lawsuit filed by a north Alabama drinking water utility over claims that the company contributed to PFOS and PFOA contamination in the Tennessee River.

The West Morgan East Lawrence Water Authority announced the partial settlement agreement Thursday, saying Daikin had agreed to settle for its alleged role in the water contamination but denied any wrongdoing.

The water authority will continue its case against the other defendants in the lawsuit, 3M and Dyneon. 3M has said it will fight the lawsuit and denies that the chemicals' presence in the water is likely to cause health or environmental problems.

Water Authority general manager Don Sims said the settlement means the Authority's customers won't have to pay for installing a new granular activated carbon filtration system that will remove those compounds from the water it takes in from the Tennessee River. He said that new filtration system is still on schedule to be operational by October.

A news release from the water authority stated that $3.9 million of the settlement will go directly to the new filter. Another $450,000 will be rebated to customers who paid higher bills over the summer for temporary measures to address the pollution, and the rest will be used to cover court costs and other fees.

"As we move into the next phase of this litigation, we look forward to announcing additional good news for the customers of the Authority as we continue the fight against 3M and other corporate polluters," the news release read.

The Water Authority serves approximately 10,000 residential customers and several businesses in Morgan and Lawrence Counties, west of Decatur, where the Daikin facility is located.

The Water Authority filed its law suit last year, but the issue of PFOS and PFOA contamination in drinking water was brought into the national spotlight on May 19, when the U.S. Environmental Protection Agency issued a health advisory stating that the chemicals could be harmful to humans in lower concentrations than previously thought.

What you need to know about Alabama water contamination

Answers to frequently asked questions about the recent recommendation not to drink water from

In June, the West Morgan East Lawrence Water Authority advised its customers not to drink their tap water until the level of the chemicals was brought below the new health advisory threshold. That all-clear came on June 23, when Gov. Robert Bentley announced that all Alabama water systems were within the new EPA threshold.

The settlement still must be approved by the courts, and would not affect any personal injury claims that individuals have made for health effects they believe were caused by the pollution.

Container ship CCNI ARAUCO fire: Sep 02 Update: fire still on, hold filled with water: the blaze was started by welding work in the hold

Container ship CCNI ARAUCO fire: Sep 02 Update: fire still on, hold filled with water

Sept. 2, 2016 at 13:52 by Mikhail Voytenko

Sep 02 1300 UTC Update: According to latest available information, fire fighting still goes on with fire alert being next to utmost. Hold with burning containers was sealed and filled with CO2 gas in the evening Sep 01, but after that, temperature began to rise again, making impossible the offloading of the containers from the hold. By noon Sep 02 temperature was still too high , fire was still on. It was decided to fill the hold with water up to 70 percent of hold’s volume, though there’s the risk, that hull may crack, due to thermal differential.

Sep 02 0230 UTC Update:
According to available information, fire fighting is still going on, part or all burning containers are in hold, which of course, complicates fire fighting. Tugs are cooling the hull by pouring water on it, temperature inside is so high, that specialist fear hull may crack. It was said, that there were no containers with dangerous goods, either on fire or near fire, but of course, it’s impossible to ascertain at present stage. Three crew understood to be injured, hopefully not seriously, during initial attempts to extinguish fire, all crew said to be evacuated.

Mega container ship CCNI ARAUCO , docked in Hamburg, Burchardkai, reportedly under major fire, after an explosion at around 1300 LT Sept 01, which took place aft, understood in container. Some 80 fire fighting teams said to be deployed.

More than 30 hours after ignition, the fire in the hold of the container vessel CCNI Arauco continues to burn, say authorities with the Hamburg Fire Department – and efforts to combat the final remaining pockets of the blaze may continue through the weekend.

Three attempts to extinguish the fire by filling the after hold compartment with CO2 were not successful, and in consultation with the vessel’s operator the firefighting team moved to flood the compartment with water. Responders used water supplied from shore and from the multipurpose emergency response vessel Neuwerk to partially fill the hold through the vents; the hatch covers remained in place.

As of Friday evening, the hold was flooded as much as the vessel's stability would allow, and pumping in more water is not a possibility, the fire department said.

"The next step is a comprehensive foam attack from the water side and the land side . . . it will be redundant so that the foam attack is not interrupted," the agency said in an online update.

The depth of the fire’s location within the hold has added complexity to the response by limiting responders’ ability to access the source.

Emergency services personnel from other cities have joined the effort, including Bremerhaven's specially trained team of 10 marine firefighters.

The Hamburg fire department confirmed that the 1,250 tonnes of dangerous goods on board the Arauco are located well forward and safely away from the blaze.

Authorities believe that the blaze was started by welding work in the hold, which led to the spread of a fire belowdecks. Three workers suffered minor injuries in the fire and were taken to a hospital.

Fiery head-on I-77 collision in SC that killed 2 and injured 11 was caused by speeding or reckless 2007 International tractor-trailer driver who also died in the crash

UPDATED 1:30 PM EDT Sep 02, 2016
CHESTER COUNTY, S.C. —A fiery crash that shut down Interstate 77 in Chester County on Thursday killed two people, including the tractor-trailer driver who caused the crash, South Carolina Highway Patrol troopers said.

Troopers said the wreck was reported just before 3:30 p.m. on I-77 at mile marker 68.

The driver of a 2007 International tractor-trailer and an 82-year-old passenger in one of the vehicles were killed in the crash, troopers said.

The names of the two victims were still not released as of 1 p.m. Friday as the coroner's office worked to identify them.

Eleven people, including a 2-year-old, a 13-year-old and a 16-year-old were taken by helicopter and ambulance to a nearby hospital. Some had life-threatening injuries, highway patrol said.

Troopers said four of the vehicles involved were headed north on the interstate at a low speed because of traffic congestion.

The International tractor-trailer driver rear-ended a vehicle causing a chain-reaction, troopers said.

The tractor-trailer driver then crossed the median, hitting another tractor-trailer headed south, according to troopers.

Both tractor-trailers caught fire, troopers said.

The interstate was closed in both directions for several hours. All lanes were reopened by 11 p.m.

A passing motorist, Gregory K. Barefoot, of Union County, took photos of the fiery wreck, sharing them on Ulocal and posting to his Facebook page.

Fiery head-on I-77 collision in SC that killed 2 and injured 11 was caused by speeding or reckless 2007 International tractor-trailer driver who also died in the crash. He will not do that again.

Preventing Electrocutions of Crane Operators and Crew Members Working Near Overhead Power Lines

DHHS (NIOSH) Publication Number 95-108

Note: This publication supercedes 85-111

WARNING! Crane operators and crew members may be electrocuted when they work near overhead power lines.
The National Institute for Occupational Safety and Health (NIOSH) requests assistance in preventing electrocutions of crane operators and crew members working near overhead power lines. Recent NIOSH investigations suggest that employers, supervisors, and workers may not be fully aware of the hazards of operating cranes near overhead power lines or may not implement the proper safety procedures for controlling these hazards. This Alert describes five cases (six electrocutions) that resulted from such hazards and makes recommendations for preventing similar incidents. The Alert updates a previous NIOSH Alert published in July 1985 [NIOSH 1985].
The recommendations in this Alert should be followed by all employers, managers, supervisors, and workers in companies that use cranes or similar boomed vehicles. NIOSH requests that the following individuals and organizations bring this Alert to the attention of workers who are at risk: editors of trade journals, safety and health officials, construction companies, unions, suppliers and manufacturers of building materials, crane manufacturers, electric utilities, and others who use cranes or boomed vehicles.

Workers are killed each year when cranes contact overhead power lines.

Background

Data from the NIOSH National Traumatic Occupational Fatalities (NTOF) Surveillance System indicate that electrocutions accounted for approximately 450 (7%) of the 6,400 work-related deaths from injury that occurred annually in the United States during the period 1980-89 [NIOSH 1993a]. Each year an average of 15 electrocutions were caused by contact between cranes or similar boomed vehicles and energized, overhead power lines. The actual number of workers who died from crane contact with energized power lines is higher than reported by NTOF because methods for collecting and reporting these data tend to underestimate the total number of deaths [NIOSH 1993a]. More than half of these crane-related electrocutions occurred in the construction industry.

FACE Data

From 1982 through 1994, NIOSH conducted 226 onsite investigations of work-related electrocutions under the Fatality Assessment and Control Evaluation (FACE) Program. Twenty-nine (13%) of these incidents (which resulted in 31 fatalities) involved crane contact with overhead power lines. Nearly half of the incidents occurred in the construction industry. Because the FACE investigations were conducted in only 16 states, these fatalities represent only a portion of the crane-related electrocutions during the period 1982-94.

OSHA Data

A study conducted by the Occupational Safety and Health Administration (OSHA) showed that 377 (65%) of 580 work-related electrocutions occurred in the construction industry during the period 1985-89 [OSHA 1990]. Nearly 30% (113) of these electrocutions involved cranes.

Current Standards

OSHA Regulations

Current OSHA regulations require employers to take precautions when cranes and boomed vehicles are operated near overhead power lines. Any overhead power line shall be considered energized unless the owner of the line or the electric utility company indicates that it has been de-energized and it is visibly grounded [29 CFR 1926.550 (a)(15)(vi)]. The OSHA regulations are summarized as follows:

Employers shall ensure that overhead power lines are de-energized or separated from the crane and its load by implementing one or more of the following procedures:
De-energize and visibly ground electrical distribution and transmission lines [29 CFR 1910.333(c)(3); 29 CFR 1926.550(a)(15)]
Use independent insulated barriers to prevent physical contact with the power lines [29 CFR 1910.333(c)(3); 29 CFR 1926. 550(a)(15)]
Maintain minimum clearance between energized power lines and the crane and its load [29 CFR 1910.333(c)(3)(iii); 29 CFR 1926.550(a)(15)(i), (ii), (iii)].

Where it is difficult for the crane operator to maintain clearance by visual means, a person shall be designated to observe the clearance between the energized power lines and the crane and its load [29 CFR 1926.550(a)(15)(iv)].
The use of cage-type boom guards, insulating links, or proximity warning devices shall not alter the need to follow required precautions [29 CFR 1926.550 (a)(15)(v)]. These devices are not a substitute for de-energizing and grounding lines or maintaining safe line clearances.

ANSI Standard

The American National Standards Institute (ANSI) has published a standard for mobile and locomotive cranes that includes operation near overhead power lines [ANSI 1994]. This consensus standard (B30.5-1994) contains guidelines for preventing contact between cranes and electrical energy. The standard addresses the following issues:

Considering any overhead wire to be energized unless and until the person owning the line or the utility authorities verify that the line is not energized
De-energizing power lines before work begins, erecting insulated barriers to prevent physical contact with the energized lines, or maintaining safe clearance between the energized lines and boomed equipment
Limitations of cage-type boom guards, insulating links, and proximity warning devices
Notifying line owners before work is performed near power lines
Posting warnings on cranes cautioning the operators to maintain safe clearance between energized power lines and their equipment

CSA Recommendations

The Construction Safety Association of Ontario, Canada (CSA) recommends safe work practices in addition to those addressed in the OSHA and ANSI standards [CSA 1982]. These recommendations include the following.

Work Practices

Operate the crane at a slower-than-normal rate in the vicinity of power lines.
Exercise caution near long spans of overhead power lines, since wind can cause the power lines to sway laterally and reduce the clearance between the crane and the power line.
Mark safe routes where cranes must repeatedly travel beneath power lines.
Exercise caution when travelling over uneven ground that could cause the crane to weave or bob into power lines.
Keep all personnel well away from the crane whenever it is close to power lines.
Prohibit persons from touching the crane or its load until a signal person indicates that it is safe to do so.

The CSA recommendations also address the limitations of proximity warning devices, hook insulators, insulating boom guards, swing limit stops, nonconductive taglines, ground rods, and similar devices for protection against electrical hazards.

Procedures to Follow If Contact Occurs

To protect against electrical shock injury in the event of contact between a crane and an energized line, the CSA recommends the following:

The crane operator should remain inside the cab.
All other personnel should keep away from the crane, ropes, and load, since the ground around the machine might be energized.
The crane operator should try to remove the crane from contact by moving it in the reverse direction from that which caused the contact.
If the crane cannot be moved away from contact, the operator should remain inside cab until the lines have been de-ener gized.

Case Reports

The five cases presented here were investigated by the NIOSH FACE Program between March 1990 and March 1993.

Case No. 1--One Death

On March 1, 1990, a 29-year-old worker was electrocuted when he pushed the crane cable on a 1-yard cement bucket into a 7,200-volt power line. The victim was a member of a crew that was constructing the back concrete wall of an underground water-holding tank at a sewage treatment plant. Before work on the tank began, the company safety director made sure that insulated line hoses were placed over sections of the power line near the jobsite and that a safe clearance zone was marked off for arriving cement trucks to use for loading their cement buckets.
After the wall was poured, the driver of the cement truck cleaned the loading chute on his truck with a water hose mounted on the truck. As he began to pull away, the crew supervisor yelled to him, asking if the crew could use his water hose to wash out the cement bucket suspended from the crane. The driver stopped the truck under the power line and the crane operator (not realizing that the truck had been moved) swung the boom to position the bucket behind the truck. The victim grasped the handle of the bucket door and pushed down to open it, bringing the crane cable into contact with the power line. The victim provided a path to ground and was electrocuted [NIOSH 1990b].

Case No. 2--One Death

On August 11, 1990, a 33-year-old well driller was electrocuted when a metal pipe lifted by a truck-mounted crane contacted a 12,000-volt overhead power line. The victim and a coworker were repairing a submersible pump for a water well at a private residence. The well was located in a pasture with three parallel power lines overhead. One of the power lines passed directly over the well (32 feet above the ground). On the day of the incident, the victim positioned the truck-mounted crane beneath the power line. Using a handheld remote-control pendant, the victim fully extended the end of the boom 36 feet above the ground. The crane cable was attached to a 1-inch-diameter galvanized pipe that ran to the pump inside the well. As the victim raised the pipe, it contacted the power line directly above the well, energizing the crane and the handheld remote-control pendant. The victim provided a path to ground and was electrocuted [NIOSH 1990c].

Case No. 3--One Death

On August 22, 1990, a 24-year-old foreman for a telecommunications company was electrocuted when he grabbed the door handle on a truck-mounted crane whose boom was in contact with a 7,200-volt overhead power line. The foreman and three other workers (a lineman, a cable splicer, and a laborer) were attempting to remove four poles that had supported a billboard. The poles stood 20 feet high and were buried 5 feet in the ground. They were located 15 feet away from (and parallel to) the power line. To remove the poles, the lineman positioned the crane directly under the power line. He controlled the crane boom while standing on the ground using rubber-coated hand controls mounted on the back of the truck. The poles were removed by hooking the crane boom cable around the middle of each pole and vertically pulling each pole out of the ground. While the workers were pulling out the third pole, the end of the boom contacted the overhead power line. The laborer (who was working in the back of the truck) noticed that the lineman was being shocked and was unable to let go of the hand control. The laborer kicked the lineman in the chest and the lineman fell unconscious to the ground. He revived without assistance about 3 minutes later with electrical burns to his left hand. However, the crane boom remained in contact with the power line, the truck tires ignited, and the truck began to burn. When the foreman noticed that the boom remained in contact with the power line, he tried to open one of the truck doors (presumably to move the truck). When his hand contacted the door handle, he provided a path to ground and was electrocuted [NIOSH 1990a].

Case No. 4--One Death

On June 24, 1991, a 37-year-old construction laborer was electrocuted while pulling a wire rope attached to a crane cable toward a load. The choker was to be connected to a steel roof joist that was to be lifted 150 feet across the roof of a one-story school and set in place. The cab of the crane was positioned 11 feet 6 inches from a 7200-volt power line. After a previous roof joist had been set in place, the crane operator swung the crane boom and cable back toward the victim, who grabbed the choker in his left hand. With his right hand, he held onto a steel rod that had been driven into the ground nearby. At this point, the momentum of the swinging crane apparently caused the crane cable to contact the power line. The electrical current passed across the victim's chest and through the steel rod to ground, causing his electrocution [NIOSH 1991].

Case No. 5--Two Deaths

On March 31, 1993, a 20-year-old male truck driver and his 70-year-old male employer (the company president) were electrocuted when the boom of a truck-mounted crane contacted a 7,200-volt conductor of an overhead power line. The incident occurred while the driver was unloading concrete blocks at a residential construction site. The driver had backed the truck up the steeply sloped driveway under a power line at the site and was using the crane to unload a cube of concrete blocks. The company president and a masonry contractor watched as the driver operated the crane by a handheld remote-control unit.

The driver was having difficulty unloading the blocks because the truck was parked at a steep angle. While all three men watched the blocks, the tip of the crane boom contacted a conductor of the overhead power line and completed a path to ground through the truck, the remote control unit, and the driver.

The company president attempted to render assistance and apparently contacted the truck, completing a path to ground through his body. He died on the scene. The truck driver was airlifted to a nearby burn center where he later died as a result of electrical burns [NIOSH 1993b].

Conclusions

These case reports indicate that some crane operators, their employers and supervisors, and others who work around cranes may not be fully aware of the hazards of operating cranes near overhead power lines or may not implement the proper safety procedures for controlling these hazards.

Recommendations

NIOSH recommends that employers take the following measures to protect workers and operators of cranes and other boomed vehicles from contacting energized overhead power lines.

Comply with OSHA Regulations

Train workers to comply with current OSHA regulations. These regulations require workers and employers to consider all overhead power lines to be energized until (1) the owner of the lines or the electric utility indicates that they are not energized, and (2) they have been visibly grounded [29 CFR 1910.333 (c)(3); 29 CFR 1926.550(a)(15)].
Employers shall ensure that overhead power lines are de-energized or separated from the crane and its load by implementing one or more of the following [29 CFR 1910.333(c)(3); 29 CFR 1926.550(a)(15)]:
- De-energize and visibly ground electrical distribution and transmission lines at the point of work
- Use insulated barriers that are not a part of the crane to prevent contact with the lines
- If the power lines are not de-energized, operate cranes in the area ONLY if a safe minimum clearance is maintained as follows:
  - At least 10 feet for lines rated 50 kilovolts or below
  - At least 10 feet plus 0.4 inch for each kilovolt above 50 kilovolts; or maintain twice the length of the line insulator (but never less than 10 feet)
Where it is difficult for the crane operator to maintain safe clearance by visual means, designate a person to observe the clearance and to give immediate warning when the crane approaches the limits of safe clearance [29 CFR 1926.550(a) (15)(iv)].
Do not use cage-type boom guards, insulating links, or proximity warning devices as a substitute for de-energizing and grounding lines or maintaining safe clearance [29 CFR 1926.550(a)(15)(v)].

Follow ANSI Guidelines

Train workers to follow ANSI guidelines for operating cranes near overhead power lines (ANSI Standard B30.5-1994, 5-3.4.5)[ANSI 1994]. These guidelines recommend posting signs at the operator's station and on the outside of the crane warning that electrocution may occur if workers do not maintain safe minimum clearance that equals or exceeds OSHA requirements as follows:

Power line voltage phase to phase (kV)	Minimum safe clearance (feet)
50 or below	10
Above 50 to 200	15
Above 200 to 350	20
Above 350 to 500	25
Above 500 to 750	35
Above 750 to 1,000	45

Notify Power Line Owners

Before beginning operations near electrical lines, notify the owners of the lines or their authorized representatives and provide them with all pertinent information: type of equipment (including length of boom) and date, time, and type of work involved. Request the cooperation of the owner to de-energize and ground the lines or to help provide insulated barriers.

NIOSH encourages employers to consider de-energization (where possible) as the primary means of preventing injury from contact between cranes and power lines.

Develop Safety Programs

Develop and implement written safety programs to help workers recognize and control the hazards of crane contact with overhead power lines.

Evaluate Jobsites

Evaluate jobsites before beginning work to determine the safest areas for material storage, the best placement for machinery during operations, and the size and type of machinery to be used.

Know the location and voltage of all overhead power lines at the jobsite before operating or working with any crane.

Research has shown that it is difficult to judge accurately the distance to an overhead object such as a power line [Middendorf 1978]. Therefore, NIOSH recommends that no other duties or responsibilities be assigned when workers are designated to observe clearance during crane movement or operation.

Evaluate Alternative Work Methods

Evaluate alternative work methods that do not require the use of cranes. For example, it may be possible to use concrete pumping trucks instead of crane-suspended buckets for placing concrete near overhead power lines. Alternative methods should be carefully evaluated to ensure that they do not introduce new hazards into the workplace.

Train Workers

Ensure that workers assigned to operate cranes and other boomed vehicles are specifically trained in safe operating procedures. Also ensure that workers are trained (1) to understand the limitations of such devices as boom guards, insulated lines, ground rods, nonconductive links, and proximity warning devices, and (2) to recognize that these devices are not substitutes for de-energizing and grounding lines or maintaining safe clearance.

Workers should also be trained to recognize the hazards and use proper techniques when rescuing coworkers or recovering equipment in contact with electrical energy. CSA guidelines list techniques that can be used when equipment contacts energized power lines [CSA 1982] (see Current Standards in this Alert).
All employers and workers should be trained in cardiopulmonary resuscitation (CPR).

Call for Help

Ensure that workers are provided with a quick means of summoning assistance when an emergency occurs.

Develop Safer Equipment

Encourage the manufacturers of cranes and other boomed vehicles to consider developing truck-mounted cranes with electrically isolated crane control systems, such as those that use fiber optic conductors to transmit control signals.

Construction contractor electrocuted to death at home construction site while he was assisting a crane operator with moving roofing frames

September 1, 2016
Updated September 1, 2016 5:18pm

A 46-year-old Kalaheo man was electrocuted Wednesday morning at a home construction site in Lawai, Kauai.

The Kauai County Police Department has identified the man as Gary Wiser, a contractor who was working at the site on Hailima Road at 10 a.m., when the incident occurred while he was assisting a crane operator with moving roofing frames off the roadway and onto the home’s property on Hailima Road.

According to reports, Wiser was standing on the ground and holding the cable connected to the crane’s boom when he was apparently electrocuted by an overhead power line. Wiser collapsed, and bystanders began CPR until firefighters and medics arrived.

Medics transported Wiser to Wilcox Hospital, where he was pronounced dead. Foul play is not suspected. An autopsy is pending.

Police spokeswoman Sarah Blane said officers are investigating.

Preventing Electrocutions of Crane Operators and Crew Members Working Near Overhead Power Lines

May 1995

DHHS (NIOSH) Publication Number 95-108

Note: This publication supercedes 85-111

Workers are killed each year when cranes contact overhead power lines.

Background

FACE Data

OSHA Data

Current Standards

OSHA Regulations

Employers shall ensure that overhead power lines are de-energized or separated from the crane and its load by implementing one or more of the following procedures:
De-energize and visibly ground electrical distribution and transmission lines [29 CFR 1910.333(c)(3); 29 CFR 1926.550(a)(15)]
Use independent insulated barriers to prevent physical contact with the power lines [29 CFR 1910.333(c)(3); 29 CFR 1926. 550(a)(15)]
Maintain minimum clearance between energized power lines and the crane and its load [29 CFR 1910.333(c)(3)(iii); 29 CFR 1926.550(a)(15)(i), (ii), (iii)].

Where it is difficult for the crane operator to maintain clearance by visual means, a person shall be designated to observe the clearance between the energized power lines and the crane and its load [29 CFR 1926.550(a)(15)(iv)].
The use of cage-type boom guards, insulating links, or proximity warning devices shall not alter the need to follow required precautions [29 CFR 1926.550 (a)(15)(v)]. These devices are not a substitute for de-energizing and grounding lines or maintaining safe line clearances.

ANSI Standard

Considering any overhead wire to be energized unless and until the person owning the line or the utility authorities verify that the line is not energized
De-energizing power lines before work begins, erecting insulated barriers to prevent physical contact with the energized lines, or maintaining safe clearance between the energized lines and boomed equipment
Limitations of cage-type boom guards, insulating links, and proximity warning devices
Notifying line owners before work is performed near power lines
Posting warnings on cranes cautioning the operators to maintain safe clearance between energized power lines and their equipment

CSA Recommendations

Work Practices

Operate the crane at a slower-than-normal rate in the vicinity of power lines.
Exercise caution near long spans of overhead power lines, since wind can cause the power lines to sway laterally and reduce the clearance between the crane and the power line.
Mark safe routes where cranes must repeatedly travel beneath power lines.
Exercise caution when travelling over uneven ground that could cause the crane to weave or bob into power lines.
Keep all personnel well away from the crane whenever it is close to power lines.
Prohibit persons from touching the crane or its load until a signal person indicates that it is safe to do so.

Procedures to Follow If Contact Occurs

To protect against electrical shock injury in the event of contact between a crane and an energized line, the CSA recommends the following:

The crane operator should remain inside the cab.
All other personnel should keep away from the crane, ropes, and load, since the ground around the machine might be energized.
The crane operator should try to remove the crane from contact by moving it in the reverse direction from that which caused the contact.
If the crane cannot be moved away from contact, the operator should remain inside cab until the lines have been de-ener gized.

Case Reports

The five cases presented here were investigated by the NIOSH FACE Program between March 1990 and March 1993.

Case No. 1--One Death

Case No. 2--One Death

Case No. 3--One Death

Case No. 4--One Death

Case No. 5--Two Deaths

Conclusions

Recommendations

NIOSH recommends that employers take the following measures to protect workers and operators of cranes and other boomed vehicles from contacting energized overhead power lines.

Comply with OSHA Regulations

Train workers to comply with current OSHA regulations. These regulations require workers and employers to consider all overhead power lines to be energized until (1) the owner of the lines or the electric utility indicates that they are not energized, and (2) they have been visibly grounded [29 CFR 1910.333 (c)(3); 29 CFR 1926.550(a)(15)].
Employers shall ensure that overhead power lines are de-energized or separated from the crane and its load by implementing one or more of the following [29 CFR 1910.333(c)(3); 29 CFR 1926.550(a)(15)]:
- De-energize and visibly ground electrical distribution and transmission lines at the point of work
- Use insulated barriers that are not a part of the crane to prevent contact with the lines
- If the power lines are not de-energized, operate cranes in the area ONLY if a safe minimum clearance is maintained as follows:
  - At least 10 feet for lines rated 50 kilovolts or below
  - At least 10 feet plus 0.4 inch for each kilovolt above 50 kilovolts; or maintain twice the length of the line insulator (but never less than 10 feet)
Where it is difficult for the crane operator to maintain safe clearance by visual means, designate a person to observe the clearance and to give immediate warning when the crane approaches the limits of safe clearance [29 CFR 1926.550(a) (15)(iv)].
Do not use cage-type boom guards, insulating links, or proximity warning devices as a substitute for de-energizing and grounding lines or maintaining safe clearance [29 CFR 1926.550(a)(15)(v)].

Follow ANSI Guidelines

Power line voltage phase to phase (kV)	Minimum safe clearance (feet)
50 or below	10
Above 50 to 200	15
Above 200 to 350	20
Above 350 to 500	25
Above 500 to 750	35
Above 750 to 1,000	45

Notify Power Line Owners

Preventing Electrocutions from Contact Between Cranes and Power Lines

July 1985

DHHS (NIOSH) Publication Number 85-111

Note: This publication has been superceded by 95-108

Background

Contact between cranes and overhead power lines is a major cause of fatal occupational injuries in the United States. Based upon an analysis by the National Institute for Occupational Safety and Health (NIOSH) of the data from the Supplementary Data System [1] of the Bureau of Labor Statistics, there were approximately 2,300 lost workday occupational injuries in the United States in 1981 which resulted from contact with electrical current by crane booms, cables, or loads. These 2,300 injuries were extremely severe, resulting in 115 fatalities and 200 permanent total disabilities. Comparable statistics obtained in studies conducted by the National Safety Council from 1965 to 1976 produced an estimated annual average of 150 fatalities resulting from such incidents [2]. NIOSH believes that this type of event is the most common cause of fatalities associated with mobile crane operations [3] and is responsible for approximately 1.5% of all fatal work-related injuries each year.

Case Reports

As part of the Fatal Accident Circumstances and Epidemiology (FACE) Project conducted by NIOSH, six fatal injuries involving crane-related electrocutions were investigated. The synopses of these cases are as follows:

Case #1:

A 28-year-old construction worker was holding on to a steel ladder being moved by a telescoping boom crane. As the crane's boom was swung in the direction of 7,200 volt power lines, the cable contacted the closest of the lines and the worker was electrocuted.

Case #2:

A co-owner of a steel erection company and three workers were using a telescoping boom crane to move a section of a steel framing member at the construction site of a commercial storage shed. As the section was moved, it came into contact with a 23,000 volt overhead power line. Two of the three workers who were in direct contact with the load were electrocuted while the third received serious electrical burns.

Case #3:

Roof materials for an addition to a commercial building were stored outside the building directly beneath a 7,200 volt power line. While hooking a load (joist angle bracing) to the crane, a worker was electrocuted when the cable came into contact with the power line as the boom swung.

Case #4:

A construction company was in the process of laying concrete water pipe with a crane. As workmen were placing support timbers beneath the crane's outrigger pads, the operator began extending the crane boom for the next lift when the boom came into contact with a 3 phase 13,800 volt overhead power line. One worker touching an outrigger of the crane was electrocuted.

Case #5:

At a highway construction site, a carpenter attached a 4' x 8' wood and metal form to a crane. While holding on to the form in attempting to guide it into place, the carpenter was electrocuted when the boom or cable came into contact with a 34,000 volt power line.

Appropriate Standards and Recommended Work Practices

The Occupational Safety and Health Administration (OSHA) Safety and Health Regulations for Construction, Subpart N--Cranes, Derricks, Hoists, Elevators, and Conveyors (29 CFR 1926.550(a)(15))--contains specific requirements for the safe use of cranes proximate to overhead power lines. Electrical distribution and transmission lines are required to be de-energized and visibly grounded, moved, or separated from cranes with independent insulating barriers. The regulation states that when it is not possible to meet these requirements, cranes may operate proximate to power lines only if:

a) minimum clearance (absolute limit of approach) is maintained between the crane and the lines (10 feet for <50 kV and 10 feet plus 0.4 inch for each 1 kV over 50 kV, or twice the length of the line insulator but never less than 10 feet);
or,

b) in transit with no load and boom lowered, minimum clearance (absolute limit of approach) is maintained (4 feet for <50 kV, 10 feet for 50 kV to 345 kV, or 16 feet for up to and including 750 kV).

Additionally, 1926.550(a)(15) requires that: a person be designated to observe the clearance of the crane when it is difficult for the crane operator to use direct observation; cage-type boom guards, insulating lines, or proximity warning devices may be used, but their use does not eliminate the need to adhere to the other parts of the regulation; any overhead wire is to be considered energized until the owner of the line or the electric utility indicates that it is not energized and that it has been visibly grounded; transmitter towers should also be de-energized or tests shall be conducted to determine if an electrical charge has been induced on the crane.

Induced charges shall be dissipated by providing an electrical ground directly to the upper rotating structure supporting the boom; ground jumper cables shall be attached to materials when an electrical charge is induced; crews shall be provided with nonconductive poles to attach the ground cable to the load; combustible and flammable materials shall be removed from the immediate area prior to operations.

The Construction Safety Association of Ontario, Canada (CSA-Ontario), recommends safe work practices [4] beyond those addressed in the OSHA standard including the use of nonconductive taglines to guide loads and the use of insulating personal protective equipment by exposed workers.

Application of Existing Standards and Recommended Work Practices

Table 1 presents an analysis for each of the five cases described in this alert regarding compliance with the OSHA standard or CSA-Ontario recommended work practices. In two of the cases, neither the OSHA standard nor the CSA-Ontario recommended work practices were being followed.

In the remaining three cases, only one of these safe work practices (avoiding the storage of materials directly under power lines) was being followed. In each of these five cases, there was demonstrable lack of compliance with the OSHA standard.

TABLE 1

Status of Compliance with OSHA Standards (or Use of CSA-Ontario Recommended Work Practices) in Operations Which Resulted in Six Crane-related Electrocutions

Relevant OSHA Standard (or CSA-Ontario Recommended Work Practice)	Status of Compliance by Case
		#1	#2	#3	#4
1. Move, insulate, or de-energize power line before starting work (OSHA)	No	No	No	No	No
2. Maintain recommended absolute limit of approach (minimum clearance) for specific voltage (OSHA)	No	No	No	No	No
3. Utilize a signal man (OSHA)	No	No	No	No	No
4. Utilize nonconductive taglines, rather than direct contact, to stabilize load (CSA-Ontario)	No	No	No	No	No
5. Do not store combustible material directly beneath power lines (OSHA & CSA-Ontario)	No	Yes	No	Yes	Yes
6. Use boom guards, insulating lines, or proximity warning devices in addition to other requirements (OSHA)	No	No	No	No	No
7. Use insulating boots and gloves when workers connect loads or contact the crane while in the vicinity of overhead power lines (CSA-Ontario)	No	No	No	No	No

No = Data demonstrated lack of compliance with the OSHA standard (or lack of use of CSA-Ontario recommended work practices).
Yes = Data demonstrated compliance with the OSHA standard (or use of CSA- Ontario recommended work practices).

Conclusion

The principal objective of the investigations undertaken by NIOSH as part of its Fatal Accident Circumstances and Epidemiology (FACE) Project is to determine what factors enabled the fatality to occur. The goal is to learn how such fatalities can be prevented. In this context, whether or not an operation was "in compliance" with existing standards is but one of many variable which may or may not have contributed to the fatality.

However, in the course of the investigations reported here, it became obvious that full compliance with relevant OSHA standards and full use of the CSA-Ontario work practices would have prevented each fatality.

As an obvious first step in preventing such fatalities in the future, we conclude that all such operations should be done only in compliance with existing OSHA standards.

RECOMMENDATIONS BY NIOSH

The existing OSHA standard appears sufficient to prevent the crane-related electrocutions described in this alert as well as all others. NIOSH urges all employers who use cranes in the vicinity of overhead power lines to familiarize themselves with and implement the existing OSHA standard. NIOSH urges safety and trade associations, crane manufacturers, electric utility companies, and OSHA state consultative services to bring this standard to the attention of employers who use cranes. Implementation of the work practices described by the CSA of Ontario can provide an additional margin of safety.

Suggestions, requests for additional information on safe work practices, or questions related to this announcement should be directed to Mr. John Moran, Director, Division of Safety Research, 944 Chestnut Ridge Road, Morgantown, West Virginia 26505-2888, Telephone (303) 291-4595.
