■ Do not take any action that could ignite the fuel gas. Do

not operate any electrical switches. Do not pull any power supply or extension cords. Do not light matches or a ny ot h er so u rce of fl a me. Do not us e you r telephone.

■ Get everyone out of the building and away from the area

immediately.

■ Close all propane gas tank or cylinder fuel supply

valves, or the main fuel supply valve located at the meter if you use natural gas.

■ Propane gas is heavier than air and may settle in low

areas. When you have reason to suspect a propane leak, keep out of all low areas.

■ Lack of proper ventilation air will lead to improper

combustion.

■ Improper combustion can lead to carbon monoxide

poisoning in humans leading to serious injury or death. Symptoms of carbon monoxide poisoning can include headaches, dizziness and difficulty in breathing.

■ Symptoms of improper combustion affecting livestock

can be disease, lower feed conversion, or death.

■ Learn to recognize the odor of propane gas and natural

gas. Local propane gas dealers and your local natural gas supplier (utility) will be more than happy to give you a “scratch and snif f” pamphlet. Use it to become familiar with the fuel gas odor.

■ Smoking can decrease your ability to smell. Being

around an odor for a period of time can affect your sensitivity to that particular odor. Odors present in animal confinement buildings can mask fuel gas odor.

ATTENTION -- CRITICAL POINTS TO REMEMBER!

■ Propane gas and natural gas have a distinctive odor.

Learn to recognize these odors. (Reference “Fuel Gas Odor” and “Odor Fading” sections above.

■

If you have not been properly trained in repair and service of propane gas and natural gas fueled heaters, then do not attempt to light the heater, perform service or repairs, or make any adjustments to the heater on a propane gas or natural gas fuel system.

■ If there is an underground leak, the movement of gas

through the soil can filter the odorant.

■ Propane gas odor may differ in intensity at different

continue to detect any gas odor, no matter how small, treat it as a serious leak. Immediately go into action as discussed previously.

■ Even if you are not properly trained in the service and

repair of radiant heaters, ALWAYS be consciously aware of the odors of propane gas and natural gas.

■ A periodic “snif f test” around the heater or at the

heater’s joints; i.e. hose, connections, etc., is a good safety practice under any conditions. If you smell even a small amou nt of gas, CONTACT YOUR FUEL GAS SUPPLIER IMMEDIATELY. DO NOT WAIT!
