DISASSEMBLY
WARNING
Repairing components by means of grinding, cutting, and/or welding produces hot,
flying particles. These particles can cause serious injury to personnel. These hot
particles can also ignite fires in the work area and in adjacent spaces. During and after
work, the work area will be very hot. Protective goggles, gloves, and/or aprons must be
worn at all times during cutting and grinding operations. A fire watch must be posted
whenever grinding or cutting operations are taking place. Failure to comply can result
in damaged equipment and serious injury or death to personnel.
Unprotected exposure to arc welding rays can cause serious eye damage and radiation
burns to the skin. Never perform arc welding operations without using appropriate eye
and skin protection. Failure to comply can result in serious injury or death to personnel.
! CAUTION
Improper connection of ground leads can cause serious electrolytic and electronic
damage to the vessel and its components. Always ensure that ground leads are con-
nected in accordance with TB 55-1900-204-24.
NOTE
All welding must be done by a qualified welder in accordance with S9074-AQ-GIB-010/248.
