LP gas and natural gas have man-made odorants added specifically for detection of fuel gas leaks.

If a gas leak occurs, you should be able to smell the fuel gas.

THAT’S YOUR SIGNAL TO GO INTO IMMEDIATE ACTION!

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 any other source of flame. Do not use your

telephone.

Get everyone out of the building and away from the area

immediately.

Close all propane (LP) gas tank or cylinder fuel supply

valves, or the main fuel supply valve located at the

meter if you use natural gas.

Propane (LP) 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.

Natural gas is lighter than air and can collect around

rafters or ceilings.

Use your neighbor’s phone and call your fuel gas

supplier and your fire department. Do not re-enter the

building or area.

Stay out of the building and away from the area until

declared safe by the firefighters and your fuel gas

supplier.

FINALLY, let the fuel gas service person and the

firefighters check for escaped gas. Have them air out

the building and area before you return. Properly

trained service people must repair the leak, check for

further leakages, and then relight the appliance for you.

WARNING

Do not use this heater for heating human living

quarters.

Do not use in unventilated areas.

The flow of combustion and ventilation air must not be

obstructed.

Proper ventilation air must be provided to support the

combustion air requirements of the heater being used.

Refer to the specification section of the heater’s

Owner’s Manual, heater dataplate, or contact the

L.B. White Company to determine combustion air

ventilation requirements of the heater.

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.

Asphyxiation Hazard

Some people cannot smell well. Some people cannot

smell the odor of the man-made chemical added to

propane (LP) or natural gas. You must determine if

you can smell the odorant in these fuel gases.

Learn to recognize the odor of propane (LP) gas and

natural gas. Local propane (LP) gas dealers and your

local natural gas supplier (utility) will be more than

happy to give you a scratch and sniff 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.

The odorant in propane (LP) gas and natural gas is

colorless and the intensity of its odor can fade under

some circumstances.

If there is an underground leak, the movement of gas

through the soil can filter the odorant.

Propane (LP) gas odor may differ in intensity at different

levels. Since propane (LP) gas is heavier than air, there

may be more odor at lower levels.

Always be sensitive to the slightest gas odor. If you

continue to detect any gas odor, no matter how small,

treat it as a serious leak. Immediately go into action as

discussed previously.

Safety Precautions

FUEL GAS ODOR

ODOR FADING -- NO ODOR DETECTED

ATTENTION -- CRITICAL POINTS TO REMEMBER!

Propane (LP) 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 (LP) gas and natural gas fueled heaters, then

do not attempt to light heater, perform service or repairs,

or make any adjustments to the heater on propane (LP)

gas or natural gas fuel system.

Even if you are not properly trained in the service and

repair of the heater, ALWAYS be consciously aware of

the odors of propane (LP) gas and natural gas.

A periodic sniff 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

amount of gas, CONTACT YOUR FUEL GAS SUPPLIER

IMMEDIATELY. DO NOT WAIT!
