Steps
Review the definitions in 1926.1401 on osha.gov, where 'crane/derrick' is used as a combined term covering equipment within Subpart CC's scope
Confirm the equipment's method of support and boom/mast configuration to determine whether crane-specific or derrick-specific provisions in Subpart CC apply to it
Check 1926.1400 for the overall scope and any exclusions that might remove the equipment from Subpart CC entirely (e.g., certain dedicated equipment types)
Confirm which operator certification, inspection, and assembly/disassembly provisions apply to the specific equipment configuration rather than assuming identical treatment to a standard crane
When in doubt, check OSHA's published Subpart CC FAQ or a current standard interpretation letter for the specific equipment configuration
Known gotchas
Subpart CC treats 'crane' and 'derrick' under a combined regulatory framework, but specific provisions (e.g., certain assembly/disassembly or inspection sections) can still apply differently depending on configuration — do not assume total equivalence
Some derrick-type or fixed lifting equipment may fall under different OSHA general industry standards instead of Subpart CC depending on the work being performed — confirm scope before applying construction crane rules
