(d) Equipment. If equipment engines are operating in the area of the spill and they are to be shut down, the
engine speed should be cut back to idle before the engine is shut off. This is a precaution against backfiring.
(e) Cleanup. If the fuel is AVGAS, MOGAS, or JP-4, a large spill should be blanketed with fire extinguisher foam
as soon as possible to reduce danger of fire or to put out the fire if one exists. After the immediate emergency is
over, go to your appropriate response plan document prepared in accordance with AR 200-1 for instructions on
whom to call. For example, the document may tell you to call a fuel spill removal organization to do this type of
work at your site. Make sure that arrangements for experienced cleanup personnel are in place before an actual
large spill occurs. Until cleanup help arrives, it may be best to rope off the area, post a guard, close down nearby
refueling operations, and allow the spill to evaporate. Use the FSSP spill kit to contain and cleanup the spill to the
extent you can. The spill area should not be used for operations again until it is free of fuel vapors.
