THE SILENT KILLER: 8 PEOPLE, INCLUDING 7 CHILDREN, FOUND DEAD IN MARYLAND HOME FROM CARBON MONOXIDE POISONING

Authorities would not confirm any information about possible carbon monoxide poisoning, but Princess Anne police Chief Scott Keller told The AP that there was no foul play and that a generator with no gasoline was found in the kitchen. He confirmed that the electricity to home was turned off and said officers were looking into when that began.

Matt Likovich, a spokesman for Delmarva Power, would not say whether the power to the home had been cut off. He said the matter is being investigated.

PRINCESS ANNE, MARYLAND

(Reuters) - Eight family members, including seven children between the ages of 6 and 16, were found dead in a Maryland home on Monday, possibly due to carbon monoxide poisoning, local media and police said.

Princess Anne, Maryland police said in a statement that a citizen called to report a missing co-worker. When police arrived at the home, on Antioch Avenue, they found it locked and undisturbed.

When police entered the home, they found one adult and seven children dead. Police said no foul play is suspected, but did not give a cause of death in the release.

Delmarvanow.com, a Gannett news website, quoted police as saying the deaths were caused by carbon monoxide poisoning. Princess Anne police said in their statement that the case was still under investigation, and gave no further details.

Princess Anne is a town of about 3,300 located about 134 miles southeast of Baltimore.

Stephanie Wells, who works with the adult victim –– his name was not confirmed by police –– said she last saw him on March 28.

March 28 was the last day anyone had spoken to any of the victims, Keller said.

Wells, food service supervisor at the University of Maryland Eastern Shore, was the adult victim's supervisor. He worked in dining services doing whatever was needed, from taking out the trash to cooking on the grill. He had worked there since August 2014.

He was also a nice and helpful person who would always talk about his kids, she said.

"He was my big teddy bear," she said.

He didn't come into work on Saturday and he would generally call if that were the case, so she became concerned. And although she later filed a report with the police, she wasn't expecting the result to be what happened.

Onlookers gathered and consoled each other on Antioch Avenue and Beckford Avenue as police began removing the eight bodies from the home Monday afternoon.

As many people drove through the small Lower Shore town, down the narrow side streets that make up the surrounding neighborhoods, they stopped at stop signs to talk to others who had just learned the details themselves.

Emergency officials said crisis counselors will be in Somerset County Public Schools this week to help with grieving students.

The adult male victim, whose age was not released, was the father of the deceased juveniles, Keller said.

Keller said the Office of the Chief Medical Examiner in Baltimore will make the determination on the cause of death. There were no signs of foul play in the incident, he said.

Police were sent to the home in the 30000 block of Antioch Avenue on Monday to check on the father after a coworker reported he had not shown up to work without calling his employer.

After gaining access into the home at about 1 p.m. Monday, Keller said police found a gas generator in the kitchen that had run out of fuel. Keller added the home's electricity was not in service, but could not speak to how long the home had been without power.

When police entered the home, they could tell something was wrong.

"They knew right away that there weren't any live people in there," Keller said.

According to the Centers for Disease Control and Prevention, unintentional exposure to carbon monoxide caused an average of 430 deaths a year nationwide between 1999 and 2010. Maryland averaged 1.43 deaths per 1 million people from the gas from 1999 to 2004, while the national rate was 1.53 deaths.

A 2006 gas leak at an Ocean City hotel took the lives of a father and a daughter. Carbon monoxide poisoning was to blame. Ocean City Town Council amended its 2007 law that mandates carbon monoxide detectors in hotels and condo buildings, removing an exemption that allowed some units not to have them.

HOW TO PREVENT CARBON MONOXIDE POISONING THIS WINTER. VENTILATE ENCLOSED OR SEMI-ENCLOSED SPACES.

http://metroforensics.blogspot.com/2014/12/carbon-monoxide-poisoning-and-how-to.html

What is carbon monoxide?

Carbon monoxide, or CO, is an odorless, colorless gas that can cause sudden illness and death.

Where is CO found?

CO is found in combustion fumes, such as those produced by cars and trucks, small gasoline engines, stoves, lanterns, burning charcoal and wood, and gas ranges and heating systems. CO from these sources can build up in enclosed or semi-enclosed spaces. People and animals in these spaces can be poisoned by breathing it.

What are the symptoms of CO poisoning?

The most common symptoms of CO poisoning are headache, dizziness, weakness, nausea, vomiting, chest pain, and confusion. High levels of CO inhalation can cause loss of consciousness and death. Unless suspected, CO poisoning can be difficult to diagnose because the symptoms mimic other illnesses. People who are sleeping or intoxicated can die from CO poisoning before ever experiencing symptoms.

How does CO poisoning work?

Red blood cells pick up CO quicker than they pick up oxygen. If there is a lot of CO in the air, the body may replace oxygen in blood with CO. This blocks oxygen from getting into the body, which can damage tissues and result in death. CO can also combine with proteins in tissues, destroying the tissues and causing injury and death.

Who is at risk from CO poisoning?

All people and animals are at risk for CO poisoning. Certain groups — unborn babies, infants, and people with chronic heart disease, anemia, or respiratory problems — are more susceptible to its effects. Each year, more than 400 Americans die from unintentional CO poisoning, more than 20,000 visit the emergency room and more than 4,000 are hospitalized due to CO poisoning. Fatality is highest among Americans 65 and older.

How can I prevent CO poisoning from my home appliances?

• Have your heating system, water heater and any other gas, oil, or coal burning appliances serviced by a qualified technician every year.
• Do not use portable flameless chemical heaters (catalytic) indoors. Although these heaters don't have a flame, they burn gas and can cause CO to build up inside your home, cabin, or camper.
• If you smell an odor from your gas refrigerator's cooling unit have an expert service it. An odor from the cooling unit of your gas refrigerator can mean you have a defect in the cooling unit. It could also be giving off CO.
• When purchasing gas equipment, buy only equipment carrying the seal of a national testing agency, such as the CSA Group.
• Install a battery-operated or battery back-up CO detector in your home and check or replace the battery when you change the time on your clocks each spring and fall.

How do I vent my gas appliances properly?

• All gas appliances must be vented so that CO will not build up in your home, cabin, or camper.
• Never burn anything in a stove or fireplace that isn't vented.
• Have your chimney checked or cleaned every year. Chimneys can be blocked by debris. This can cause CO to build up inside your home or cabin.
• Never patch a vent pipe with tape, gum, or something else. This kind of patch can make CO build up in your home, cabin, or camper.
• Horizontal vent pipes to fuel appliances should not be perfectly level. Indoor vent pipes should go up slightly as they go toward outdoors. This helps prevent CO or other gases from leaking if the joints or pipes aren't fitted tightly.

How can I heat my house safely or cook when the power is out?

• Never use a gas range or oven for heating. Using a gas range or oven for heating can cause a build up of CO inside your home, cabin, or camper.
• Never use a charcoal grill or a barbecue grill indoors. Using a grill indoors will cause a build up of CO inside your home, cabin, or camper unless you use it inside a vented fireplace.
• Never burn charcoal indoors. Burning charcoal — red, gray, black, or white — gives off CO.
• Never use a portable gas camp stove indoors. Using a gas camp stove indoors can cause CO to build up inside your home, cabin, or camper.
• Never use a generator inside your home, basement, or garage or near a window, door, or vent.

How can I avoid CO poisoning from my vehicle?

• Have a mechanic check the exhaust system of my car every year. A small leak in your car's exhaust system can lead to a build up of CO inside the car.
• Never run a car or truck in the garage with the garage door shut. CO can build up quickly while your car or truck is running in a closed garage. Never run your car or truck inside a garage that is attached to a house and always open the door to any garage to let in fresh air when running a car or truck inside the garage.
• If you drive a vehicle with a tailgate, when you open the tailgate, you also need to open vents or windows to make sure air is moving through your car. If only the tailgate is open CO from the exhaust will be pulled into the car.

Carbon Monoxide Hazards from Small Gasoline Powered Engines

Many people using gasoline-powered tools such as high-pressure washers, concrete cutting saws (walk-behind/hand-held), power trowels, floor buffers, welders, pumps, compressors, and generators in buildings or semi enclosed spaces have been poisoned by carbon monoxide (CO). CO can rapidly accumulate (even in areas that appear to be well ventilated) and build up to dangerous or fatal concentrations within minutes. Examples of such poisonings include the following:

• A farm owner died of CO poisoning while using an 11-horsepower, gasoline-powered pressure washer to clean his barn. He had worked about 30 minutes before being overcome.
• A municipal employee at an indoor water treatment plant lost consciousness while trying to exit from a 59,000-cubic-foot room where he had been working with an 8-horse-power, gasoline-powered pump. Doors adjacent to the work area were open while he worked. His hospital diagnosis was CO poisoning.
• Five workers were treated for CO poisoning after using two 8 horse-power, gasoline-powered, pressure washers in a poorly ventilated underground parking garage.
• A plumber used a gasoline-powered concrete saw in a basement with open doors and windows and a cooling fan. He experienced a severe headache and dizziness and began to act in a paranoid manner. His symptoms were related to CO poisoning.

These examples show a range of effects caused by CO poisoning in a variety of work settings with exposures that occurred over different time periods and with different types of ventilation. Workers in areas with closed doors and windows were incapacitated within minutes. Opening doors and windows or operating fans does NOT guarantee safety. CO is a dangerous poison. Operating gasoline-powered engines and tools indoors is RISKY BUSINESS.

Recommendations

It is not widely known that small gasoline-powered engines and tools present a serious health hazard. They produce high concentrations of CO--a poisonous gas that can cause illness, permanent neurological damage, and death. Because it is colorless, odorless, and nonirritating, CO can overcome exposed persons without warning. Often there is little time before they experience symptoms that inhibit their ability to seek safety. Prior use of equipment without incident has sometimes given users a false sense of safety; such users have been poisoned on subsequent occasions. Recommendations for preventing CO poisoning are provided below for employers, equipment users, tool rental agencies, and tool manufacturers.
All Employers and Equipment Users Should:

• NOT allow the use of or operate gasoline-powered engines or tools inside buildings or in partially enclosed areas unless gasoline engines can be located outside away from air intakes. Use of gasoline-powered tools indoors where CO from the engine can accumulate can be fatal.
• An exception to this rule might be an emergency rescue situation in which other options are not available--and then only when equipment operators, assisting personnel, and the victim are provided with supplied-air respirators.
• Learn to recognize the symptoms and signs of CO overexposure: headache, nausea, weakness, dizziness, visual disturbances, changes in personality, and loss of consciousness. Any of these symptoms and signs can occur within minutes of usage.
• Always place the pump and power unit of high-pressure washers outdoors and away from air intakes so that engine exhaust is not drawn indoors where the work is being done. Run only the high-pressure wash line inside.
• Consider the use of tools powered by electricity or compressed air if they are available and can be used safely. For example, electric-powered tools present an electrocution hazard and require specific precautions for safety.
• If compressed air is used, place the gasoline-powered compressor outdoors and away from air intakes so that engine exhaust is not drawn indoors where the work is being done.
• Use personal CO monitors where potential sources of CO exist. These monitors should be equipped with audible alarms to warn workers when CO concentrations are too high or when exceeding the NIOSH Ceiling limit for CO of 200 parts per million.

Employers Should Also:

• Conduct a workplace survey to identify all potential sources of CO exposure.
• Educate workers about the sources and conditions that may result in CO poisoning as well as the symptoms and control of CO exposure.
• Always substitute with less hazardous equipment if possible. Use equipment that allows for the placement of gasoline-powered engines outdoors at a safe distance from air entering the building.
• Monitor employee CO exposure to determine the extent of the hazard.

Equipment Users Should Also:

• Substitute with less hazardous equipment whenever possible. Use electric tools or tools with engines that are separate from the tool and can be located outside and away from air intakes.
• Learn to recognize the warning symptoms of CO poisoning.
• If you have any symptoms, immediately turn off equipment and go outdoors or to a place with uncontaminated air.
• Call 911 or another local emergency number for medical attention or assistance if symptoms occur. Do NOT drive a motor vehicle--get someone else to drive you to a health care facility.
• Stay away from the work area until the tool has been deactivated and measured CO concentrations are below accepted guidelines and standards.
• Watch coworkers for the signs of CO toxicity.

Tool Rental Agencies Should:

• Put warning labels on gasoline-powered tools. For example:
• WARNING--CARBON MONOXIDE PRODUCED DURING USE CAN KILL--DO NOT USE INDOORS OR IN OTHER SHELTERED AREAS.
• Tell renters that gasoline-powered tools should NOT be used indoors and explain why.
• Recommend safer tools for the intended use if available.
• Have portable, audible CO monitors for rent and encourage their use.
• Provide renters with educational materials like this information sheet.

Tool Manufacturers Should:

• Design tools that can be used safely indoors.
• Provide warning labels for existing and new gasoline-powered equipment. For example:
• WARNING--CARBON MONOXIDE PRODUCED DURING USE CAN KILL--DO NOT USE INDOORS OR IN OTHER SHELTERED AREAS.
• Provide recommendations for equipment maintenance to reduce CO emissions.
• Recommend the use of portable, audible CO monitors with small gasoline-powered engines.
