Diesel fuel is flammable and diesel fuel vapors can be explosive. Make sure all
work is performed in a well ventilated area. Keep sparks, open flame, and exces-
sive heat away from the work area. Failure to comply with this precaution can
result in death or serious injury.
Avoid prolonged exposure of the skin to diesel fuel. Protective nitrile gloves and
chemical protective goggles must be worn whenever handling diesel fuel or parts,
which are saturated with diesel fuel. Failure to comply with this precaution can
result in serious injury.
