Washington Crane Certification: WAC 296-155 Part L Explained

Washington runs its own crane program under RCW 49.17.420 and WAC 296-155 Part L. Every crane operated in the state needs an annual inspection and proof load test by an accredited crane certifier, and a certificate of operation posted in the cab that is valid for one year. Unlike federal OSHA, Washington requires written shift inspections kept three months. Operators need an accredited certification plus documented crane hours and a substance abuse test.

The Washington checklist at a glance

Requirement	Rule	What it means for you

Certificate of operation in the cab	RCW 49.17.420(3)-(4); WAC 296-155-53114(7)-(8)	Valid one year; post it in the cab or with the manual; digital copy OK
Written shift inspections	WAC 296-155-53405(4)	Items, results, name, signature, date; keep 3 months
Certifier reviews history	WAC 296-155-53200(1)	Maintenance records, 3 months of shift inspections, last annual
Decertification events	WAC 296-155-53214	Stop work, email L&I within 24 hours, re-inspect before use
Operator certification	WAC 296-155-53300	Accredited cert, documented hours, substance abuse test
Rigger and signal person	WAC 296-155-53306, -53302	Documented tests; renew every 5 years

Annual certification and the certificate of operation

RCW 49.17.420(2)(c): "Crane owners must ensure that cranes are inspected and load proof tested by a certified crane inspector at least annually and after any significant modification or significant repairs of structural parts."

Then (3): "any crane operated in the state must have a valid temporary or final certificate of operation issued by the certified crane inspector or department posted in the operator's cab or station." Certificates are valid for one year.

WAC 296-155-53114 fills in the mechanics:

• The certifier issues a worksheet/annual certificate of operation if inspection and proof load testing found no deficiencies affecting safe operation.
• The certifier submits the completed worksheet to L&I within five days of the inspection.
• Findings that need watching but do not affect safe operation are noted on the worksheet as monitor items.
• The certifier attaches an identification sticker to the crane, and its number goes on the worksheet.
• The certificate is valid one year from the date the inspection and load test occurred.
• It must be posted in the cab or with the operator's manual. "An accessible digital copy in the operator's cab or with the operator's manual will satisfy this requirement," but the owner must provide a paper copy on request.

Written shift inspections, kept three months

This is the biggest difference from federal OSHA, where shift inspections do not have to be written down.

WAC 296-155-53405(3) lists the shift items, which track the federal list: controls, drive mechanisms, pressurized lines, hydraulic fluid, hooks and latches, reeving, rope, electrical, tires, ground conditions, level, cab windows, rails, safety devices and operational aids, and guy tension on derricks.

Then (4): "Shift inspection records must be kept ... and be made available upon request. Electronic records are acceptable. These inspection records must be kept for at least three months." The record shows the items checked and results, and the inspector's name, signature and date.

Two more details in 53405:

• If a qualified person decides a deficiency is not a hazard yet but needs monitoring, it "must be checked during the shift inspections."
• A crane idle three months or more needs a qualified person's inspection before use.

And at certification time, WAC 296-155-53200(1) says the certifier must review maintenance records of critical components, "crane shift inspections from the prior three months, and the last annual inspection documentation." So missing shift sheets show up at your annual.

Decertification: when the certificate stops counting

WAC 296-155-53214, amended effective September 5, 2025, lists the events that immediately stop crane work and suspend the certification:

• Contact with an energized power line
• Any overload other than a proof load test or one approved in writing in advance by the manufacturer or an RPE
• Damage, modification or repair of a load-bearing part that affects safe operation, beyond routine maintenance
• A deficiency affecting safe operation identified by a qualified person or by L&I
• A tip-over

The owner emails [email protected] with the certification number and a short description within 24 hours. An accredited certifier must reinspect before the certification is reinstated, and proof load testing is required after major repairs to load-bearing parts. Replacing hoist rope does not decertify the crane.

Operators

WAC 296-155-53300 requires, before someone operates covered equipment:

• A valid certificate for the crane type from an accredited testing organization
• Training and an employer evaluation (the same idea as federal 1926.1427(f))
• Crane hours of experience per the rule's Table 3, documented by crane type and capacity; a signed declaration from the operator is acceptable
• A substance abuse test confirmed by a recognized laboratory

See crane operator qualification vs certification.

Riggers and signal persons

Washington goes further than the federal rules here too. Both riggers (WAC 296-155-53306) and signal persons (WAC 296-155-53302) must pass documented tests, have documentation at the site while employed, and renew at least every five years with a documented exam. See rigger and signal person qualification.

Bare rentals in Washington

L&I's own Q&A tells lessors that "renters (lessees) will ask you for a copy of the temporary or annual certificate of operation and may ask for crane maintenance records." If you rent bare, the certificate goes out with the crane. See bare rental vs operated rental paperwork.

Common Washington slip-ups

• Shift sheets done but not signed, or tossed weekly
• The certificate of operation lapses because the annual was booked late, and the crane cannot legally operate
• A power-line touch or overload goes unreported because "nothing broke"
• A new operator with a valid card but no documented crane hours or substance abuse test on file
• The temporary certificate is in the cab, but nobody followed up to confirm the annual certificate was issued

What to keep in a Washington crane file

1. Current certificate of operation (temporary or annual), with the expiry date
2. The certifier's worksheet and any monitor items
3. Three months of signed shift inspections, minimum
4. Maintenance records for critical components
5. Any decertification notice and reinstatement
6. Operator, rigger and signal person files with expiry dates

Where CraneFile fits

We're building CraneFile with a handful of crane shops, starting with Washington and California because their paperwork load is heaviest. The operator's shift sheet goes in from a phone, offline if needed, and three months of signed sheets are ready when the certifier or a GC asks. It is not live yet. If you want in early, reserve a spot or call Patrick at (786) 471-4419.
