Steps
Fetch current WAC 296-155 Part L text via app.leg.wa.gov or L&I's chapter PDF, focusing on the annual certification and inspection sections
Confirm cranes/derricks in scope (per WAC 296-155-52900, excluding subsection (3) exemptions) must be inspected and proof-load tested annually by an accredited crane certifier recognized by L&I
For tower cranes specifically, confirm inspection by a certified crane/equipment inspector is required both before and after every assembly, disassembly, or reconfiguration
Confirm the crane owner must obtain a current worksheet/annual certificate of operation before the crane is used for construction work
Confirm licensed inspection companies must employ at least one crane certifier meeting WAC 296-155-53100 requirements and hold a valid L&I business license as of the certification date
Contact L&I's Crane Certification Desk to verify current accreditation status of a specific certifier/company rather than relying on a claimed accreditation
Known gotchas
This is a Washington-specific state-plan regime (not federal OSHA) — an out-of-state CCO or CIC credential does not automatically satisfy L&I's 'accredited crane certifier' requirement; verify L&I's specific recognition criteria
Exemptions exist under WAC 296-155-52900(3) — confirm a given crane is actually in scope before applying the annual proof-load testing requirement
