(Cont)
When cutting with a torch, or when welding, always
station fire watches, ready with fire extinguishers,
in the vicinity on both sides of the plate that is
being cut or welded.
Prior to cutting or welding on the ramp, remove drain
plugs on both sides of the ramp and check if ramp
interior is primer coated. If primer coated, flush
thoroughly with steam, carbon dioxide, or water.
Do not reinstall drain plugs until the cutting and/or
welding operation is completed. Failure to take this
precaution may result in explosion of accumulated
primer vapors.
When refueling, shut down the electrical system. Observe
the no smoking rule. Do not permit anyone to operate
tools or equipment which may produce sparks near
the refueling operation. Sparks or fire may
ignite the diesel fuel and produce an explosion.
Fuel oil and other petroleum products are highly
volatile in extreme heat. To minimize the possibility
of explosion, wipe up all spills at once, see that
fuel lines and valves are not leaking and pump bilges
regularly.
Before attempting to remove any compressed air system
lines or components, relieve air pressure from system.
Failure to do so may result in injury or possible
death to maintenance personnel.
Before disconnecting a line in the hydraulic system,
bleed the pressure from that portion of the line.
Failure to do so may result in injury or possible
death to maintenance personnel.
When working inside the hydraulic oil supply tank,
a portable-type circulating blower should be used
to prevent vapor accumulation. For extended work
periods inside the tank, an air line tube respira-
tor should be worn. Station an observer outside tank
in case worker is overcome by fumes.
