Fire damage investigation and assessment involves three tasks:

  • Task 1

    Document the extent of fire damage using visual observations, physical, mechanical and metal 1urgical examination.

  • Task 2

    Map the heat exposure zones for the area, using temperature indicating observations collected in Task 1 and the following criteria:

    • Zone 1

      Ambient; no fire exposure

    • Zone 2

      Ambient to 150 F; smoke and water exposure

    • Zone 3

      150 to 400 F; light heat exposure

    • Zone 4

      400 to 800 F; moderate heat exposure

    • Zone 5

      800 to 1350F; heavy heat exposure

    • Zone 6

      > 1350 F; severe heat exposure

  • Task 3

    Based on the locations of equipment in the various heat exposure zones, assign individual items of equipment to the following categories for further action:

    • Category A

      Return to service with no further action.

    • Category B

      Test for function or properties, re-assign to Category A or C.

    • Category C

      Repair or refurbish before further use.

    • Category D

      Replace. Do not re-use.
