rewmen, now that the portable
fire extinguisher in your ammo
carrier is filled with carbon dioxide
(CO

) instead of Halon, you’ve got a
whole new set of safety concerns.
If they’re not used right, CO

extinguishers pose some dangers—
including severe frostbite and suffo-
cation. So, follow these tips for safe
CO

use:
1.
Shout a warning to all crew-
members before using the fire
extinguisher.

rewmen, checking the track on your
M113-series vehicle is a life or death
matter.
Several soldiers have been killed
in recent accidents because they
didn’t follow the suspension system
PMCS in their -10 TMs. Those TMs
spell out critical maintenance checks
and deadlining information, such as:
•
Never extend the track adjuster more
than 17 inches or it may buckle during
operation.
•
Use the track and sprocket gauge, NSN
5220-01-041-9920, to check wear limits
for sprockets and cushions.
•
Eyeball roadwheels, idler wheels and
hubs for rubber chunking, loose
hardware, and proper lubrication.
•
Check shock absorbers for heat, leaks
and loose or missing bolts after every
operation.
All of these are after-operation
checks, but it’s a good idea to do them
before operating your vehicle, too. In
fact, the following warning will soon
be added to your -10 TMs:
Even when you’ve checked your
track, accidents still happen. That’s the
reason for the thrown track warning at
the front of your -10 TM. Learn and
practice the instructions in the warn-
ing so you’ll know
exactly
what to do
in the event of a thrown track.
WARNING
Bad track has killed/injured.
Do these checks before and
after vehicle operation.
