Task F-18 Decommissions, disassembles and removes structural, ornamental mechanical and miscellaneous components
Task Descriptor
Before disassembly and removal tasks can begin, ironworkers (generalist) must be sure that it is safe to do so, by verifying that decommissioning has been performed and documented. It is critical that systems are first decommissioned, de-energized and locked out prior to disassembly work. Once this is confirmed, ironworkers (generalist) disassemble and remove structural, mechanical and miscellaneous components.
