FOR FUEL SPILLS, REFER TO FM 10-67-1, CONCEPTS AND EQUIPMENT OF PETROLEUM
Fuel is flammable and toxic to eyes, skin, and respiratory tract. Skin/eye protection is required. Avoid
repeated/prolonged contact. Use only in well-ventilated areas. Keep away from open flames or other
sources of ignition. Post FUEL FLAMMABLE/NO SMOKING signs around the area. Be sure a fire
extinguisher is available.
Fuel on clothing can be fatal if ignited by a static discharge. If fuel gets on clothes, leave the refueling area
as soon as possible, remove clothes, and wash skin with warm, soapy water before getting dressed.
Spilled fuel creates a flammable, vapor-air mixture and fire can take place. Improper positioning of
external fuel source can cause fuel tank to overflow. Stop refueling immediately if fuel spill occurs.
