If aa ggas lleak ooccurs, yyou sshould bbe aable tto ssmell tthe ffuel ggas.
THAT’S YYOUR SSIGNAL TTO GGO IINTO IIMMEDIATE AACTION!
■ 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 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.
■ 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.
■
FI N ALLY,
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.
■
Some ppeople ccannot ssmell wwell. SSome ppeople ccannot
smell tthe oodor oof tthe mman-mmade cchemical aadded tto

smell tthe oodorant iin tthese ffuel ggases.
■ Learn to recognize the odor of propane gas and natural
gas. Local propane gas dealers 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.
■
The oodorant iin ppropane ggas aand nnatural ggas iis ccolorless
and tthe iintensity oof iits oodor ccan ffade uunder ssome
circumstances.
■ 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
levels. Since propane gas is heavier than air, there may
be more odor at lower levels.
■
Always bbe ssensitive tto tthe sslightest ggas oodor.
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.

GAS SUPPLY SIZING
The vaporization of propane is affected by several factors:
the surface area of the container, the liquid level of
propane, temperature surrounding the container, and the
relative humidity. All of these factors are specific to a site.
Therefore, a degree of experience and judgement is
required to select the proper propane supply.
Although experience is the best guide, the following
recommendations can be used as a starting point. The
table is based on experience in northern climates where
cold weather and high humidity are prevalent in the winter.
If more or less favorable conditions prevail at a specific site,
adjustments can be made on the basis of experience.
