NOTE:

To avoid injury from fire, keep all potential ignition sources
away from diesel fuel, including open flames, sparks, and
electrical resistance heating elements. Do not smoke when
refueling.
To avoid injury from fire caused by heated diesel-fuel
vapors:
Keep those people who are not directly involved in
servicing away from the engine.
Stop the engine immediately if a fuel leak is detected.
Do not smoke or allow open flames when working on
an operating engine.
Wear adequate protective clothing (face shield,
insulated gloves and apron, etc.).
To prevent a buildup of potentially volatile vapors, keep
the engine area well ventilated during operation.
