ENTRY AND EXIT

TM 10-5410-228-10

ENTRY AND EXIT

The LMS height above the ground when mounted on the ECV and low door frame present potential hazards

during entry and exit. Use extreme care when climbing or descending the ladder to avoid falling. Be alert to

the low door frame to avoid hitting your head. Also use caution when climbing and descending from the roof

of the LMS.

To prevent injury to personnel, use caution when walking through entrances to the ABS, hose assemblies

and cables are on the floor of the ABS.

CIRCUIT BREAKERS

If a circuit breaker does not stay in the on position when pressed, do not attempt to close (activate)

repeatedly since an overload condition probably exists which could be hazardous to personnel and

equipment.

R22 REFRIGERANT

Great care must be exercised to prevent contact of liquid R22 refrigerant or R22 refrigerant gas discharged

under pressure with any part of body. The extremely low temperature resulting from the rapid expansion of

the liquid or gas R22 refrigerant released under pressure can cause sudden and irreversible tissue damage

through freezing. As a minimum, personnel must wear thermal protective gloves and face shield or goggles

when working in any situation where R22 refrigerant contact with the skin or eyes is possible. Application of

excessive heat to any component in a charged system will cause extreme pressure that may result in a

rupture or explosion. Exposure of R22 refrigerant to an open flame or a very hot surface will cause a

chemical reaction in the gas to form carbonyl chloride (phosgene), a highly poisonous and corrosive gas. In

its natural state, R22 refrigerant is a colorless odorless vapor with no toxic characteristics. It is heavier than

air and in a well ventilated area will disperse rapidly. However, in an unventilated area it presents a danger

of suffocation.

PRESSURIZATION

The air beams used to raise the CBPS are pressurized. When striking, the dump caps used to remove air

from air beams may come off forcefully and strike face or body. When removing dump caps, grip firmly and

turn face away from dump cap. Under no circumstances should air beam pressure be higher than 3 psi.

Injury to personnel could result if air beam pressure is higher than 3 psi.

The hydraulic system is a pressurized system attaining pressures as high as 3,000 psi. When performing

maintenance on the hydraulic system, gloves and goggles are mandatory.
