1. Fire Prevention
Petrol is highly flammable. Petroleum vapor is explosive if ignited. Do not smoke while handling
petrol, and keep away from heat, sparks, and open flames.
2. Ventilation
Petroleum vapor is heavier than air and if inhaled in large quantities will not support life. Engine
exhaust gases are harmful to breathe. When test-running an engine indoors, maintain good venti-
lation.
3. Spillage
Remember that fuel remains in the fuel hose between the fuel joint and the carburettor. Drain all
remaining fuel out into a container, or soak it up with a cloth so that the fuel does not spill on to
the bottom cowling.
4. Leaks
Failure to check for and correct fuel leaks may result in fire or explosion.
