Key Hazards
- Fire from heaters placed too close to combustibles
- Carbon monoxide exposure from fuel-fired heaters
- Electrical overloads or damaged cords
- Burns from hot surfaces
- Improper fueling or fuel storage
- Unattended heaters in work areas
2–3 Minute Talk Script
Portable heaters can make cold work areas more comfortable, but they also introduce fire, burn, electrical, fuel, and air quality hazards. A heater should never be treated as harmless just because it is small or commonly used.
Heaters must be kept away from combustible materials. Cardboard, paper, rags, clothing, plastic, sawdust, chemicals, curtains, furniture, and stored materials can ignite if they are too close to the heat source.
Fuel-fired heaters require proper ventilation. Kerosene, propane, diesel, and other combustion heaters can create carbon monoxide and other fumes if used in enclosed or poorly ventilated spaces.
Workers should only use heaters approved for the location and task. Indoor use, outdoor use, damp areas, garages, shops, temporary structures, and confined spaces may all require different equipment and precautions.
Electrical heaters should be plugged in safely. Damaged cords, overloaded circuits, extension cords, power strips, or loose outlets can create fire and shock hazards.
Fuel should be stored, handled, and added according to instructions. Refueling a hot heater, spilling fuel, using the wrong fuel, or storing fuel near ignition sources can create serious fire hazards.
Heaters should not be left unattended unless the equipment is designed and approved for that use. Workers should make sure heaters are turned off, cooled, and secured when the area is no longer occupied.
Safe heater use means controlling the area around the heater, the air quality in the work area, and the energy source feeding it. Warmth should not come at the cost of fire or carbon monoxide exposure.
Safety Reminders
- Keep heaters away from combustible materials.
- Use only heaters approved for the location.
- Provide ventilation for fuel-fired heaters.
- Watch for carbon monoxide hazards.
- Do not overload circuits or use damaged cords.
- Handle and store fuel safely.
- Turn heaters off when they are not being safely supervised.
Ask the Crew
- Is the heater approved for this work area?
- Are combustibles kept far enough away?
- Is ventilation adequate for the type of heater being used?
- Are cords, plugs, fuel lines, or tanks in safe condition?
- Will the heater be supervised and shut down properly?
