Pump bulb to purge engine fuel
Dear Half-Mast,
We’ve been getting some new BA-5800A/U lithium-sulfur dioxide
batteries for our PLGRs and chemical agent monitors (CAMs).
The shipping container for this new
battery does not have the DOT Class 9
handling label on it like the old BA-5800/U
container did.
According to TB 43-0134, Battery
Disposition and Disposal, the Class 9 label
means the contents are hazardous material.
Does no label mean these batteries aren’t hazardous? Does this
change our disposal procedure?
SGT R. J. A.
PLGRs, CAMs . . .
Dear Sergeant R. J. A.,
The new BlueStar BA-5800A/U batteries are still hazardous and your storage,
handling and disposal procedures have not changed.
The absence of a Class 9 label means this new battery passed tests that allow
it to be shipped as non-dangerous goods. But, it still is hazardous material and
must be treated as such when it reaches your shop.

!
Fuel hose connections are metal,
while fuel cans are plastic, so take it
easy screwing in the fuel hose. If you
force it, you can strip the threads and
ruin the can. If the hose connector is
hard to turn, reposition it and try again.
To purge the burner, pull the suction
hose out of the fuel can, but leave the
return line in the can. Run the engine
until fuel stops coming out of the re-
turn line.
Never take
the return line
out of the can
before the
engine is shut
off—unless
you want a
high-pressure
fuel shower.
Don’t crimp fuel lines
At the end of operations, purge both
the engine and burner to get rid of all
remaining fuel. To purge the engine,
shut it off and unscrew the fuel line
from the can. Pull up the line so it
can’t draw more fuel. Then pump the
bulb in the line until no more fuel
comes out.
Be careful closing the cover for the
burner fuel lines. If you crimp the lines,
the burner won’t start. Plus the cover’s
edge can cut the lines and they leak. If
the heater won’t start, make the fuel
lines your first check.
Screw fuel hose on carefully
