Safety Contract
GENERAL SAFETY TIPS Propane is involved in far fewer accidents
or fires than electricity, but like electricity, there are some simple safety
rules to follow to ensure your safety.
A Pressure Situation The propane
in your gas system is stored under pressure. While it's stored, there's no
problem. But, in the unlikely event your system develops a leak (which can be
caused by physical damage or deterioration), it can become dangerous. Propane burns at an even rate when properly mixed with air, as in your stove or
furnace. But, if a leak occurs, a flame or spark could ignite it. If that
happens, it could cause a fire or even an explosion. Although such accidents are
rare, we want you to be aware of this possibility. Know Your Propane System
Your propane system has four basic parts:
- A tank or cylinder, equipped with
a main shutoff valve;
- One or more regulators designed to reduce pressure
between the container and your appliance(s);
- Gas piping, to carry the
propane to your appliance(s); and
- Gas appliance(s).
The tank or
cylinder is where the propane is stored. It is equipped with a shutoff valve,
which turns the gas "on" or "off". The regulator controls the gas pressure,
while the gas piping carries the gas to your appliance(s). It is important
for you to know the location of the main shutoff valve on the tank or cylinder.
Remember its location and become familiar with how to shut it off in an
emergency situation. How Do You Tell if There Is a Leak?
- By smell. A
disagreeable odor is added to the propane so that you will be able to detect the
smell easily in case a leak develops or an unlit burner is left turned on.
- By electronic gas alarm. If used, the gas alarm supplements a person's ability
to detect a gas leak and sounds a warning when it detects the presence of
unburned propane.
You should be aware that some persons have different
thresholds of smell and cannot detect the odor of propane as readily as others.
Also, sometimes people with a normal sense of smell temporarily lose their
ability to detect odors because of illness, use of tobacco, alcohol or drugs.
Also, cooking odors, tobacco smoke and aerosol and odor removing sprays can
cover up other odors. In certain instances, the odorant in the propane may
diminish or weaken, making it difficult for a person with a normal sense of
smell to detect a gas leak. Be aware that being heavier than air, leaking
propane may tend to settle near the floor while dissipating into the air.
Steps to Take if You Smell Gas or the Alarm Sounds Never assume that the
odor of gas is a sign that your tank is running low. If you smell gas in the
house or if the gas alarm signals the presence of gas, IMMEDIATELY follow these
suggestions:
DO...
- Everyone should vacate the building, vehicle or
area.
- Move away without using any electric switches, appliances,
thermostats, or telephones.
- Close the gas shutoff valve on the propane
tank or cylinder.
- Once away from the location call your propane supplier
and/or your local fire department from a cellular telephone or a neighbor’s
telephone.
- Even if you do not continue to smell propane, do not open or
turn on the propane supply valve. Do not re-enter the building, vehicle or area.
Let a qualified propane service technician and/or emergency personnel check for
escaped propane.
- Have a properly trained propane service technician repair
the leak. The propane service technician or emergency responder needs to
determine that the leak situation has been fully resolved. The propane service
technician should check your entire gas system and take all necessary steps to
insure that the gas system is safe before it is placed back into operation.
- Return to the building, camper, RV or area only when the service or emergency
technician indicates it is safe to do so.
DO NOT...
- Smoke
- Turn
light switches, appliances or thermostats on or off, and do not use the
telephone. A spark from one of these could ignite the gas.
- Light or try to
re-light any appliances. Leave this job to your propane supplier.
- Re-enter
the building, until the problem has been corrected.
Inspection of Your
Appliance(s) Routinely call a service technician to examine your gas
appliance(s) for any conditions that may render the appliance(s) inefficient or
unsafe for use, similar to how you have your automobile checked periodically.
All appliances, including gas, should be regularly inspected and maintained,
just as electrical appliances, to eliminate possible hazards from short circuits
and other malfunctions that could create hazards. A routine inspection should
consist of (but not be limited to) detecting any unsafe or potentially hazardous
situations, such as the following:
- Substandard and/or lack of venting
systems on appliances requiring them.
- Sootiness and/or the accumulation of
soot around interior and exterior appliance components such as around pilot
lights, appliance burners, range tops, oven components, etc. This indicates that
the appliance is not operating properly or efficiently.
- Leakage of water
around or through water heater valves, fittings or jackets. CAUTION: This should
alert you to the fact that the water heating device has some internal damage.
- Missing or damaged control components such as dials, knobs, screws, etc.
- Controls that have been tampered with (evidenced by altered design
function, missing or substituted components, etc.).
- Controls that
have been under water or subjected to flooding. Such controls may not function
properly and must be replaced.
- Unstable appliance bases and/or platforms.
Warped, rotting or substandard bases and/or platforms may collapse creating a
potentially hazardous condition.
- Problems in gas line connectors such as
kinks, corrosion, deterioration, etc. Any abnormality should be immediately
reported to your propane supplier since failure to correct these problems could
create a hazardous situation.
- Unsatisfactory operation of gas valves and
safety controls.
- Gas leakage in the appliances or piping system.
- Improper appliance and gas system installation.
A Word About Vented
Appliances Some appliances are required to have vents in order to exhaust
harmful combustion gases outside. Poisonous carbon monoxide can be produced from
improperly installed or operating appliances. Frequent headaches and nausea may
be indicators that this colorless, odorless gas is causing carbon monoxide
poisoning. To minimize the chance of this happening, follow these practices:
- Vented appliances must be installed by a qualified appliance installer.
- Do not operate vented appliances until they have been vented properly.
- After appliance installation and before each heating season, the vents and flues
should be checked for blockages and corrosion, either by a qualified installer
or a qualified service technician.
- If you buy a used appliance, have it
inspected and installed by a qualified propane appliance installer.
When
properly installed and maintained, the venting system will also keep walls and
other surfaces from overheating and possibly catching fire. Not all gas
appliances are suitable for operating on propane. If you buy a used appliance,
be sure it is listed for propane and have it installed by a qualified
technician. General Safety Precautions Here are some general safety
procedures to follow when using your propane appliance(s):
- Be alert for the
odor of propane when around a gas appliance or container.
- If you smell
gas, do not try to light the appliance. Call your propane supplier.
- Read
and follow the operating and lighting instructions and warning labels provided
by the appliance manufacturer.
- The pilot has a safety device. If you have
trouble keeping it lit, this device is warning you about a problem. Call a
service technician for assistance.
- Never force any appliance control. If
you cannot operate the knobs, switches or buttons by hand, call your supplier.
Never tamper with the controls.
Additional Safety Tips
- Keep
combustibles, such as curtains, paper, cleaning fluids, etc., away from any
energy source, including gas and electric appliances where they may cause a
fire.
- Have a B/C rated fire extinguisher readily available. Be sure it is
charged and that you and your family know how to use it.
- Gas appliances,
like humans, need oxygen (air) to function properly.
- If you smell gas near
your tank or cylinder, call your propane supplier.
- Use only listed propane
appliances. Look for the seal from a nationally recognized independent testing
laboratory.
- Use gas grills outdoors only. Use or store propane cylinders
outdoors only.
If You Run Out Of Gas Letting your propane container
run empty creates additional hazards. If you run out of gas and lose pressure in
the system, a potentially hazardous condition can result. If you do run out of
gas, follow these steps:
- Turn off all control valves on all gas appliances.
- Turn off the shutoff valve on the propane container(s).
- Call your
propane supplier to arrange for delivery, and advise them you are out of gas.
- Don't turn the gas back on yourself. Let the propane supplier do it. When
you schedule your fill, be sure it is for a time when you will be at home, so
the propane supplier can relight and check your appliances and system to assure
that they are operating properly and are leak free.
- Immediately after your
tank is refilled, have a service technician check to see that all safety
controls are functioning properly and the piping system is leak free.
If
You Move or Change Gas Appliances ALWAYS CALL YOUR PROPANE SUPPLIER WHEN YOU
NEED A GAS APPLIANCE CONNECTED OR DISCONNECTED. It is for your safety that the
gas system remain in a safe condition at all times. Should the gas system
develop a leak (or if a gas line or shut off valve remains unplugged), a fire,
explosion or serious injury could result. Properly operated and maintained,
your propane system and appliance(s) can provide you many years of
clean-burning, safe efficient service. If you have any questions once you have
read this information, or do not understand any part of it, call your supplier.
