WITH SEVERE STORM SEASON UPON US, HERE ARE SOME TIPS TO PROTECT AGAINST PROPERTY DAMAGE, BODILY INJURY IN TORNADOES, HAILSTORMS, WINDSTORMS







With storm season in full swing, Oklahomans are encouraged to take steps to protect themselves, their families and their property from damage caused by tornadoes, high winds and hail.

Hail
Hail alone causes approximately $1 billion in damage to property each year, according to the National Oceanic and Atmospheric Administration. Oklahoma Farm Bureau Insurance offers these tips in the event of a hailstorm:

• Know what’s covered under your policy. Homeowners and automobile insurance generally provides coverage for property damage caused by hail, but not all policies protect against hail damage. Double check your policy and contact your agent to ensure you have comprehensive coverage before damage occurs.
• Protect against further damage. If your property or vehicle is damaged due to severe weather, take immediate action to prevent further damage or theft as soon as it is safe to do so. Use plywood, tarps or other materials to cover broken windows and damaged rooftops, and save receipts of any materials used to make repairs. Provide these receipts to your adjuster for review and reimbursement of expenses covered by your policy. Take photos or video of the damage, and keep them on file in case you need to reference them later.
• Choose a reputable repair company. Once approved by your insurance company, select a contractor or repair shop to help fix any damage that has occurred. Be wary; it’s not unusual for scammers to pose as a repair company after a damaging storm. Choose a company that has operated in your area for several years, is insured and bonded and will give you a written guarantee for the work performed.
• Prevent damage with weather-resistant products. Advances in roofing material production have led to the development of hail and wind-resistant roofing materials, which can be an effective method for homeowners to mitigate roof damage. The national standard for roof impact resistance is a material rating system of Class 1 through 4, based on their resistance to impact testing with steel balls simulating 90-mph hailstones of varying sizes, with a Class 4 rating being the toughest.





Tornadoes and high winds
Those who find themselves driving in a tornado or high winds are encouraged to follow these safety tips from AAA Oklahoma:

• If a tornado warning is issued for your area, leave your vehicle immediately and seek shelter in a sturdy building.
• Never try to outrun a tornado. Your car or pickup will offer no protection from a twister. It is impossible to know which direction a tornado may decide to go.
• Seek shelter indoors. A basement is safest. Closets or small interior rooms are best. Stay away from south walls, west walls and all windows. Get under a solid piece of furniture or a mattress.
• If you are caught in the open with no substantial buildings available, find a ditch, ravine or low-lying area and lie flat. Stay away from roadway overpasses.
• Do not seek shelter in a mobile home. These structures, even if tied down, offer little protection from tornadoes and should be abandoned.
• Remember, wet roads mean poor traction. Conditions are most dangerous during the first 10 minutes of a heavy downpour as oil and debris wash away. Driving on wet roads in the rain is like driving on ice. Slow down. Take it easy. Allow extra time to reach your destination.
• Never use your motor vehicle’s cruise control feature in rainy weather.

BROTHER, SISTER OF RAMSEY COUNTY DROWNING VICTIM OFFER CAUTIONARY TALE: PLEASE WEAR YOUR LIFE JACKET PRIOR TO GOING TO ANY BOATING OUTING





APRIL 26, 2015

LITTLE CANADA/VADNAIS HEIGHTS, MN

Vang Houa Thao was the oldest boy in a family of eight children, competitive, smart, a college graduate with a job in the finance industry in the Twin Cities area.

But when the 27-year-old went canoeing on Sunday with two friends on tiny Twin Lake near the Little Canada/Vadnais Heights border, he made a fatal mistake.

He didn’t wear a life jacket.

“It was a ‘guy thing,’ ” his sister, Maiya Thao, 30, of La Crosse, Wis., said.
Her brother, not a good swimmer, apparently drowned when the canoe overturned. About four hours later, his body was pulled from the lake by members of the Ramsey County Sheriff’s Water Patrol and Dive Team, and family and friends grieved — and shared his story as a way to warn anyone headed onto the water.

“He could be here if he had a life-jacket,” his brother, Chia Thao, 25, said.
Vang Thao grew up in La Crosse. Kou Xiong, an elementary school classmate, was with him when they launched the canoe Sunday morning from a friend’s house.

The weekend had been an eventful one for the Thao family. Vang Thao, who had moved to St. Paul, attended a cousin’s wedding. His brother and sister were back home celebrating another sister’s graduation from Western Technical College in La Crosse.

Xiong, still dazed after his friend’s body was recovered, recalled that the water was cold, and there was panic. Xiong was helped from the lake by a neighbor, he said. He remembered his childhood friend as kind and outgoing.

As the eldest son, Vang Thao was a leader of the family, Chia Thao said. Vang was “tough,” he said, but he always looked out for his siblings, always “wanted better for you,” the brother said.

“He had so much going for him,” Chia Thao added.
“It’s so unreal,” Maiya Thao said.

His brother and sister wanted it known, too, that there were, in fact, life jackets available at the home from which the three friends launched their canoe.

Unfortunately, too many people do not wear their life jackets when they perform water activities.  Too bad, as the life jackets could save their lives one day.  Learn from the dead person’s stories.

8,500 GALLONS OF GASOLINE UP IN SMOKE IN CALIFORNIA: TANKER TRUCK FLIPS TO ITS SIDE AND CATCHES FIRE, CLOSES PORTION OF 710 FREEWAY IN BELL













APRIL 26, 2015

BELL, CALIFORNIA

A tanker truck carrying 8,500 gallons of gasoline caught fire, causing a closure of the north and southbound 710 Freeway in Bell on Sunday afternoon, officials said.

The fire was reported on the 710 Freeway near Florence Avenue, Los Angeles County Fire Department officials said around 3:45 p.m.

The truck was carrying about 8,500 gallons of gasoline, the department tweeted. Flames were extinguished by 4:54 p.m. but the roadway remained closed.

No injuries were reported, and more than 50 firefighters were deployed to battle the blaze, supervising dispatcher Cheryl Sims with the fire department told the Los Angeles Times.

Motorists were trapped on the freeway for nearly an hour, but around 4:30 p.m. southbound traffic was diverted onto Bandini Boulevard and northbound drivers were led off Florence Avenue, the CHP tweeted.

The north and southbound sides of the freeway would remain closed for an unknown amount of time, the California Highway Patrol tweeted.

Photos showed the tanker truck had overturned, and no other vehicles appeared to be involved in the crash.

Plumes of dark smoke billowed into the air as dozens of parked vehicles appeared to be stuck on the roadway, images on social media showed.

KTLA viewers reported seeing the smoke from as far away as Silver Lake.

THE ROLLOVER RISK OF TRUCKS: EVASIVE OR SUDDEN MOVES WILL RESULT IN ROLLOVER OF THE TRUCK

THE ROLLOVER RISKS OF TWO-TANK TANKERS ARE TOO GREAT TO CONTINUE TO ALLOW THEM CARRYING HAZARDOUS MATERIALS WITHOUT ADDITIONAL SAFETY MEASURES



The recent rollover of a two-car tanker in Los Angeles reminds how dangerous these two-tank tankers are for carrying flammable liquids.

The fluid slosh can definitely throw you around if you're not expecting it. You have to be smooth with your inputs.  If the driver was being stupid/distracted/whatever he could have easily steered/braked too quickly and caused the slosh to tip him over.

Tankers are actually the hardest commercial vehicle to control.  Any tanker that has to be completely cleaned out between loads cannot have baffles. Imagine the kind of things that would grow in a tanker full of milk if you could never wash it out. There are also still older tankers out there that move things such as fuel that have baffles today, but did not always have them in the past.
No question its the driver's fault, but he really could have had some surging that contributed to the incident.

Dynamic Stability of a Vehicle Carrying Bulk Liquid and Driving Over a Bump

The forces generated by the sloshing of bulk liquid carried in tanker trucks can cause accidents.  The roll-over tendency of a vehicle can be measured in terms of how many "g" (gravitational acceleration) that vehicle can withstand in cornering.  The higher this value, the safer the vehicle.  For example, full size passenger cars can withstand around 1.2 g.  For a loaded semi-truck the number is 0.4, and for half empty tanker truck it can be as bad as 0.15.  Tanker trucks are used for supplying soldiers with water and fuel.  The trucks sometimes need to operate on rough terrain at relatively high speeds.  This exposes the truck to a roll-over risk. If the tanker is partially empty, the risk of roll-over becomes much higher. 

In this project, we simulate sloshing in a tanker truck driving over a bump. The truck is moving at 10 m/s and drives over a bump 40 cm high. The suspension system of the truck absorbs the initial displacement due to the bump and transfers the generated forces to the structure of the truck. The suspension system is composed of two linear springs with different spring constants. The 3D rigid-body dynamic equations are coupled to the finite element formulation of the flow problem and solved simultaneously for the motion of the tanker truck as function of time. The fluid dynamics equations are written in a non-inertial frame to account for this motion. The finite element mesh used consists of 343,560 hexahedral elements and 357,911 nodes. At each time-step, a coupled system of nonlinear equations with 1,704,661 unknowns is solved. The computation was carried out on a CRAY T3E with 32 processors. The frames below show, at different instants, the motion of the truck, sloshing, and fluid pressure. For additional information on sloshing in tanker trucks, see "Sloshing in a Container Subjected to Sudden Deceleration".
The mesh generator and flow solver were developed by the T*AFSM.

Canada Pipelines Still Need Better Spill Response, Following the Bunker Fuel Oil Spill from the Grain Ship


Published in Oil Industry News on Saturday, 25 April 2015

Graphic for Canada Pipelines Still Need Better Spill Response, Clark Says in Oil and Gas News
A fuel spill this month off the beaches of Vancouver proves more needs to be done before British Columbia will allow construction of new heavy oil pipelines, the west coast province’s premier said.

An estimated 2,700 liters of bunker fuel leaked from the Marathassa, a grain ship in Vancouver’s English Bay, sparking political wrangling, with the mayor and province accusing the federal government of a slow response and cleanup.

The emergency heightened concern that a bigger spill would have a devastating impact on the coastal province situated between landlocked Alberta oil sands and global markets.

The Marathassa showed B.C. is not ready to contain a marine oil spill, Premier Christy Clark said.

“What we did learn is we aren’t sufficiently coordinated in the harbor between levels of government,” Clark said in a telephone interview with Bloomberg News on Friday. “We have got our work cut out for us to make sure that we raise our game on this.”

Clark laid out five conditions three years ago for major pipeline projects to be approved in her province, one of which is “world-class” marine spill response.

“None of those projects can go ahead until” the conditions are met, she said.
Enbridge Inc.’s Northern Gateway project and Kinder Morgan Inc.’s Trans Mountain expansion both have routes that would run through British Columbia.

Spill Funding

Marine-spill response is the responsibility of the federal government, which has been criticized for closing a marine base in Vancouver. Commissioner of the Canadian Coast Guard Jody Thomas said in an April 12 statement, however, that the closing “would not have changed how we responded to this incident,” since the facility was not involved in spill response.

Department of Fisheries and Oceans funding for Environmental Response Services, which handles oil spill cleanup, will be C$17 million ($13.9 million) this year, up from C$12.9 million in 2014-2015 and C$10.3 million the year before, government figures show. The number of staff has also increased.

Nonetheless, the federal New Democratic Party said it would make a motion in Parliament on Monday to reverse the closing of Vancouver’s Kitsilano coast guard facility. “This spill needs to be a wake-up call,” NDP Leader Thomas Mulcair said in a written statement. “Conservative cuts are threatening the B.C. coast.”

Containing Spill

In a written statement, a Coast Guard spokesman defended the agency’s response, saying vessels were dispatched to the spill site within 25 minutes of the first complaint and skimmers were on the water within four hours to contain the spill.

While the urgent response has been completed, the Coast Guard “will continue to clean the trace pollution that washed up on the shores of Burrard Inlet, and to monitor and plan for the potential long-term effects of the spill,” spokesman Frank Stanek said in an e-mail Monday.

Clark’s government sparred with the federal Conservatives in the days after the spill, which was reported April 8, though she struck a conciliatory tone in the interview Friday.

“This isn’t a product of one federal government not providing adequate spill response,” Clark said. “It’s a product of 50 years of federal government ignoring the West Coast’s needs in this regard. And this federal government has begun to really think about it. But we’ve to go from thinking about it, to making it happen.”
