To avoid personal injury or property damage use extreme care
in handling gasoline. Gasoline is extremely flammable and the
vapors are explosive. Serious personal injury can occur when

gasoline is spilled on yourself or your clothes which can ignite.
Wash your skin and change clothes immediately.

Thoroughly inspect the area where the equipment is to
be used. Remove all stones, sticks, wire, and other foreign
objects which could be tripped over and cause personal

When practical, remove gas-powered equipment
from the truck or trailer and refuel it on the ground.
If this is not possible, then refuel such equipment on

a trailer with a portable container, rather than from a
gasoline dispenser nozzle.
