5.5 LPG (Liquefied Petroleum Gas) System
LPG (Liquefied Petroleum Gas) is a generic term to
describe liquefied gasses consisting predominately of
Propane (C3) and Butane (C4) hydrocarbons.
5.5.1 Hazards
Extremely flammable! These gasses readily form explo-
sive air-vapor mixtures at ambient temperature.
Vapor is heavier than air and may travel to remove
sources of ignition (e.g. along drainage systems, into
bilges, etc.).
Liquid from the tanks will generate large volumes of flam-
mable vapor (approximately 250:1).
Cold burns (frostbite) will result from skin/eye contact with
liquid from the tanks.
Liquid release or vapor pressure jets present a risk of
serious damage to the eyes.
Abuse involving willful inhalation of very high concen-
trations of vapor, even for short periods, can produce
unconsciousness or might prove fatal. Inhalation may
cause irritation to the nose and throat, headache, nau-
sea, vomiting, dizziness, and drowsiness.
Unconsciousness or asphyxiation may result in poorly
ventilated or confined spaces.
5.5.2 First-Aid Measures
Eyes: Immediately flush eyes with plenty of cool water
for at least 15 minutes. Hold eyelids apart while flushing
to rinse entire surface of eye and lids with water. Get
immediately medical attention.
Skin: In case of cold burns, immediately place affected
area in warm water (41 degrees) and keep immersed
until circulation returns. Get immediate medical advice.
Other requirements: Severe inhalation or overexposure
to this material may sensitize the heart to cat echo la
mine-induced arrhythmia. Do not administer *cat echo
la mine to overexposed individuals. Contact the Poisons
Information Service and/or seek further medical advice.
*(Cat echo la mine are chemical compounds derived
from the amino and tyrosine that act as hormones or
neurotransmitters.) “Wikipedia Encyclopedia”
5.5.3 Fire-Fighting Measures
Activate emergency systems and/or sound the alarm.
Call the Fire Department. Evacuate all persons from the
area.
Ensure an escape route is always available from any fire.
If it is safe to do so, close the container valves). Allow
any gas-fueled fire to burn out. If unable to cut off supply
of gas, allow it to burn.
Keep LPG cylinders or tanks cool, as pressurized con-
tainers will explode if subjected to high temperatures.
Small LPG fires can be attacked with dry powder fire
extinguishers, provided the fuel supply can be turned off
after the fire is extinguished.
5.5.4 Accidental Release Measures
As these substances have a very low flash point, any
spillage or leak is a severe fire and/or explosion hazard.
If a leak has not ignited, stop gas flow at container, elimi-
nate all sources of ignition, and evacuate all persons.
Stay upwind of release. Inform emergency services.
Liquid leaks generate large volumes of flammable vapor,
heavier than air, which may travel to remove sources of
ignition (e.g. along drainage systems).
Where appropriate, use water spray to disperse the gas
or vapor.
Vapor may collect in any confined space.
If spillage has occurred in a confined space, ensure
adequate ventilation and check that a safe, breathable
atmosphere is present before entry.
Do not enter a vapor cloud. Only trained specialized indi-
viduals should attempt to enter a vapor cloud.
Wear protective clothing. See 5.5.7
In the event of a major leak, contact the appropriate
authorities.
Small quantities of spilled liquid may be allowed to evapo-
