REPAIR CONTINUED
4. Open side door and secure to side of container with attached door chain (TM 10-8415-222-10, Unloading).
CAUTION
Before performing the patch procedure to either an interior or exterior MTRCS wall
skin, the damaged area needs to be evaluated. If damage is to an internal structural
wall post, the damaged area cannot be patched. Further evaluation of damage to
take place at a higher level of maintenance.
The panel patch is an 8-inch by 10-inch pre-drilled metal sheet. A 1-inch minimum
overlap is required to securely attach the patch to the MTRCS skin.
5. Evaluate damaged area of skin (Figure 1, Item 1) to see if patch repair is possible using guidelines as follows:
If damaged area is limited to exterior or interior wall sheeting, wall can be patched using 8-inch by 10-inch
panel patch.
If damage is to internal structural wall post, wall cannot be patched. Notify supervisor.
If damaged area is greater than 6-inch by 8-inch in size, wall cannot be patched. Notify supervisor.
WARNING
If the container skin has been damaged, there will be sharp metal edges capable of
causing severe and deep cuts to your skin. Always wear protective gloves when
working with damaged metal surfaces.
6. Using metal cutting shears, remove as much damaged metal as possible without enlarging damaged area of
skin (Figure 1, Item 1). Make sure surface is flat after trimming.
7. Carefully press remaining damaged metal down to allow attachment of patch panel (Figure 1, Item 2).
WARNING
Rubber gloves, face and eye protection should be worn when handling any
chemicals. Failure to wear proper protective clothing may result in skin irritation
and/or serious eye injury.
8. Spray expanding foam insulation into affected area of damage until filled.
NOTE
The spray foam used for this repair is expanding type foam. The foam will expand to
completely fill the damage void.
9. Allow foam insulation to cure until hardened.
