Does this describe you, tank crewmen? If so, it’s only a matter of time before you
suffer an accident, maybe even a fatal one.
Take, for example, an incident from September of last year. An M1A1 tank
crewman was trying to close the driver’s hatch by reaching from inside the turret into
the driver’s compartment. A CVC helmet was resting on the commander’s control
handle. Turret power was on to provide lighting and the turret lock was unlocked.
When the hatch closed, the driver’s hatch interlock was disengaged. The turret
suddenly traversed to the left, pinning the crewman between the turret basket and the
driver’s compartment.

rewmen, you’d think that having a new heater hose installed in your Stryker would
stop leaks. You’d also be wrong.
The rise in temperature during
operation will cause that new hose
to expand a bit the Frst time it’s
used. That can stretch the clamps
holding the new hose in place
slightly. Then, when the hose
cools and shrinks, you get leaks.
The solution is simple. Just
check and tighten the clamps after
the Frst operation.
1.
When extending
any
part of the
body between the turret and driver’s
compartment, the turret lock must be set.
2.
The driver’s hatch must remain closed
whenever the turret or gun are unlocked
and turret power is on. You can operate
from the open hatch position only when
the turret and gun are locked.
±ortunately, this crewman only sustained injuries to his shoulder. You might not be
so lucky.
The next time you’re feeling complacent, check out TACOM Safety-of-Use
Message 96-08 for more turret safety do’s and don’ts. You’ll Fnd it on the AEPS
website:
3. Never
use the commander’s control
handle as a place to hang your CVC
helmet or other equipment. The helmet
can depress the palm switch, allowing
the turret to traverse suddenly.
