WARNING
When falling tank by means of bottom loading, defueling (M970 or M970A1), or self-loading, a test of the precheck system
is mandatory. If this system is not functioning, stop all operations. Determine the problem and have it corrected by a
qualified technician. Failure of automatic shutoff to function may result in uncontrolled fuel spillage and danger of fire
and explosion.
WARNING
When top loading through fill cover, there is no automatic shutdown. Man the loading hose to avoid fuel spillage. Use
capacity indicator gage and dipstick gage to determine amount of fuel loaded. Failure to follow this warning may result in
uncontrolled fuel spillage and a fire or explosion hazard.
WARNING
DO NOT mix incompatible fuels in tank. Dangerous fumes and explosion may result. Know what fuel was previously
carried so that preventive measures maybe taken to ensure that injurious or explosive fumes are not released. Failure to
follow this warning may result in injury or death to personnel.
WARNING
In an emergency, close valve A or pull emergency valve shutoff on opposite side of semitrailer.
WARNING
Operators must be alert for leaking or malfunctioning equipment. Stop all servicing operations immediately at the first
sign of leaks or malfunctions. Corrective action must be performed by qualified technicians before resuming any
operations.
WARNING
Parking areas for fuel servicing vehicles should be arranged to:
• Facilitate dispersal of vehicles in event of an emergency.
• Provide at least 10-feet of clear space between vehicles for accessibility for fire control purposes.
• Prevent any vehicle from draining into an adjacent building.
• Provide at least 50-feet distance from any structure housing the public, that may have windows or doors in ex-
posed walls.
WARNING
All vapor-freeing work by any method should be carried on outdoors, remote from vehicles and other known sources of
ignition, and the tank unit must be stationed where flammable vapors will not blow or drift indoors. Failure to follow this
warning may result in serious injury or death to personnel.
WARNING
Combustible vapor testing must be conducted as prescribed in this manual and current technical bulletins and field
manuals. Vapor testing should not be conducted during steam cleaning since excess moisture or lack of oxygen may cause
false readings.
