Insulation on the personnel heater ducts in
M1
tanks falls Off if it gets wet or tears. Then
-±²
when the heater is on, the metal ducts get
hot and can buR crewmen.
We keep insulation on this way:

Drivers and Loaders, when you puLL PMCS on the ´xed ´re extinguishers, see
iF there's ±een a Loss oF pressure µom one day to the next.
It's Like this:
You check the cylinder pressure
against the char¶ on t²e cyLinders. IF
pressure is OK, you're good to go.
OtheRWise, your tank is NMC.
Tomorrow (and the next time you
operate the tank) compare the press·re
readings. Do this every time you
puLL PMCS¸
IF pressure is sLowLy decreas¹ng, yo·
may have tro·bLe brew¹ng. ºLthough the
pressure decrease

co·Ld be caused by
the weather, most LikeLy there's a Leak
somew¼ere. It may not be a big Leak
now, b·t it couLd turn into a nightmare
w¼en you need to ´ght a ½Re. ¾eport it!
