Misuse of Gasoline
1. More serious burn accidents on construction jobs result from gasoline fires than
from any other single cause. Here are three typical gasoline burn accidents:
a. Burning brush while clearing site. Gasoline was thrown on pile which was smouldering. Flashback
caused severe burns.
b. Fueling generator engine. Gasoline spilled on exhaust and ignited. Worker seriously burned and
c. Gassing up rig. Gas spilled on helper's clothes and over platform close to heater. Gasoline ignited
and caught helper's clothes on fire—severe burns of right arm and leg resulted.
2. Gasoline evaporates rapidly, and the vapor can travel a considerable distance to
a source of ignition such as an open fire, hot engine, or a cigarette. The vapor is
easily ignited and very explosive.
Some rules for safe use of gasoline are:
a. Do not start fires with gasoline.
b. Do not smoke when handling gasoline.
c. Do not use gasoline for cleaning.
d. Do not put gasoline in open pails or glass containers—use a safety can.
e. Shut off all engines before refueling.
f. Small engines should be fueled slowly using a funnel to prevent spillage.
g. Watch nozzle when fueling large engines—do not allow fuel to overflow.
3. QUESTIONS FOR DISCUSSION
a. Why do so many burns occur when fueling gasoline engines?
b. Why should gasoline be used only as a motor fuel?
