2.3 Propane safety
Propane is a flammable gas whose vapors are heavier than air. As in the case with gasoline,
propane can explode if the proper cautions are not heeded. Propane is odorized with an agent
having a distinct odor that is recognizable at very low concentrations. This helps identifying
leaks, even when they are small.
Awareness and basic safety precautions are required when working with propane. As long as
these precautions are followed, risk is negligible. Ignorance, however, could pose needless
risk.
The two greatest hazards with propane powered floor machines are:
• Carbone Monoxide Poisoning: This is the most frequently reported incident associa-
ted with propane powered machines and is caused by excessive exhaust emissions. The
symptoms are headache, dizziness and nausea. A major cause involves engines with
poor preventive maintenance practices. Usually those with dirty air filters and machines
operated in confined areas without adequate ventilation. Another cause may be sub -
standard, inexpensive machines with no emission control technology and improperly
set carburetion.
• Overfill Fuel Tanks: Nearly all fire related incidents reported result from bringing a
tank into a building without first checking for overfill. This action is dangerous, unwise
and unnecessary.
2.4 Fire Safety
Beware of the potential danger of fire or explosion when using propane, and take normal
fire-safety precautions.
Fire:
There is possibilities of fire from LPG vapor Leaking or venting from fuel tanks or carbure -
tion equipment.
Explosion:
LPG vapor concentrated or confined to a small, restricted space may explode or
ignite.
Propane
may experience a BLEVE, a boiling liquid expanding vapor explosion.
2.5 Emissions
• All propane powered floor machines produce emissions. Most are harmless, but some are
dangerous and can be fatal. Carbon monoxide (CO) poses the greatest risk, since CO can be
lethal within as little as 30 minutes exposure at 3,000 parts per million (ppm) concentrations.
• Carbon monoxide is an invisible odorless colorless gas created when fossil fules (such as
gasoline, wood, coal, propane, oil and methane) burn incompletely.
2.6 Hazard Communication
A
Material Safety Data Sheet
for propane shall be posted in all buildings where propane will be
used.
Because propane is odorized, it is easily detected at levels of just a few parts per million, which
is much less than the exposure limit of 1000 parts per million.
