Now that the cold weather is here and the economy isn’t that great, we are all trying to save money. It’s tempting to use a space heater to heat a room rather than to heat the entire house. But it’s important to be cautious with this option. The U.S. Consumer Product Safety Commission estimates that more than 25,000 residential fires every year are associated with the use of room (space) heaters. More than 300 people die in these fires. An estimated 6,000 more receive hospital emergency room care for burn injuries associated with contacting hot surfaces of room heaters, mostly in non-fire situations.
Setup and Use
When setting up a space heater, remember to keep it at least 30 inches from any flammable materials and set it up on the floor, unless it is designed otherwise. Do not set them up on easily ignited or flammable surfaces, such as rugs or carpets, or use them to dry wet clothing. Electric heaters should be kept out of wet or moist places like bathrooms. Water or corrosion could lead to a fire or shock hazard.
When using a space heater in an enclosed area, it is a good idea to leave a window or door partially open to allow for fresh air to enter. This will prevent carbon monoxide (CO) buildup or a depletion of oxygen. Never take a gas-fired or kerosene heater into a confined space. The results could be deadly. All gas heaters should be equipped with a pilot safety valve. This device will shut off the gas to the heater if the pilot light should go out, preventing the risk of explosion by not allowing the accumulation of gas.
If the pilot light goes out, remember the following safety tips:
• If you smell gas, do not attempt to light the pilot. Turn off all controls, open a window or door and leave the area.
• Remember that propane is heavier than air and does not dissipate rapidly. If you smell gas, do not touch any electrical switches or use a radio or telephone in the area where you smell gas. Do not smoke. A spark could ignite the gas.
It also is a good idea to light a match before you turn on the gas to the pilot. This avoids the risk of flashback, which could occur if gas is allowed to accumulate before lighting the pilot.
Maintenance and Inspection
All gas and kerosene heaters should be inspected annually by a qualified person to ensure that they are properly adjusted and clean.
Maintenance and inspections should include checking the following items:
• Condition of safety devices
• Exhaust ducting and flues
• Efficiency of burners
• Exhaust flow
• Condition of fuel lines and tanks
• Condition of electrical cords
• Vents and gaskets
• Condition of guards
• Missing guards and controls
You should be aware of the following hazards when using propane, kerosene or electric space heaters:
1. Fires and burns caused by contact with or close proximity to the flame, heating element or hot surfaces.
2. Fire and explosion caused by flammable fuels or defective wiring.
3. Indoor air pollutants caused by improper ventilation or incomplete combustion of fuels.
4. CO poisoning caused by improper ventilation or incomplete combustion of fuels.
5. High humidity released by propane-fired heaters that can lend to mold growth within buildings under construction.
Symptoms of CO Poisoning
Symptoms of CO poisoning can mimic those of the flu or food poisoning. Early exposure symptoms may include:
Prolonged exposure can lead to the following symptoms:
• Increasing fatigue
• Lack of coordination
• Extreme weakness
• Loss of consciousness
Because CO poisoning symptoms mimic the flu or food poisoning, it is important to inform medical responders of the possibility of exposure to excessive amounts of CO. Poisoning can be reversed if caught in time, but acute poisoning may result in permanent damage to the heart and brain.
1. Get the victim into the open air as quickly as possible.
2. Check for respiration and pulse. If both are absent, begin CPR.
3. If breathing is absent, but there is a pulse, begin mouth-to-mouth resuscitation and continue until the victim begins breathing or help arrives. Have an up-to-date CPR kit with mouth protector available due to exposures to bodily fluids.
4. Begin administering oxygen as soon as one is available and if you are trained to do so.
5. Get the victim to a hospital as soon as possible.
