Dear Bonnie,
A Soldier was recently killed in a maintenance-related accident in
Afghanistan. The mechanic was performing maintenance on the front brake
calipers of an up-armored M1114 HMMWV sitting on two “bottle-jacks”
and one jack stand when the vehicle shifted and fell on him. The Soldier was
taken to a local medical facility where he died.
There is a right way to support
a vehicle. Use two jack stands
and chock the wheels. The warning
summary in TM 9-2320-387-24-
1 spells out safe procedures very
clearly. It says:
Hydraulic jacks are used for
raising and lowering, and are
not used to support vehicle.
Never
work
under
vehicle
unless wheels are blocked and
it is properly supported. Injury
or damage to equipment may
result if vehicle suddenly shifts
or moves.
Warnings and cautions in the technical manuals are there to
protect users from injury or death. When the standard is ignored,
Soldiers are at risk. Please remind your readers to go by the book.
Army safe is Army strong!
