With the cold and snowy weather fast approaching, the Westbrook Fire Department suggests residents review some basic safety guidelines before using a propane-fueled space heater to heat their homes.

There are two basic types of propane space heaters, direct-vent or vent-free. Direct-vent heaters require outside air to support combustion and are generally installed on outside walls. When using one of these heaters, residents should check the vents to make sure they are free of ice and snow.

Vent-free heaters rely on inside air to support combustion and vent directly into a room. Newer vent-free heaters come equipped with an oxygen-depletion sensor, which automatically turns the unit off if oxygen levels drop below a certain level.

Fire and rescue officials recommend that all space heaters be checked periodically. Propane distributors can send a trained technician to inspect the unit, clean the control compartments and burner and train residents in proper operation. This maintenance should be done at least once per year.

Fire officials also suggest that residents install at least one carbon monoxide detector, even if propane is not used in the home. The detectors should be installed near any space heaters, or in a central location in the home. The detectors should have their batteries changed at least twice a year.

Homeowners using propane in their homes should also be familiar with the rotten egg smell that has been added to the gas to make leaks easily identifiable. If you do smell gas, do not touch any electric switches, light matches or use the phone; leave the house immediately; if there is an outside gas tank, turn off the supply valve and call the fire department or your gas supplier from a neighbor’s phone.
