Tower Crane Erection and Dismantling Violations

Tower Crane Erection and Dismantling Hazard Alert

The Division of Occupational Safety and Health (DOSH) issued a Hazard Alert in June 2019 discussing roles, responsibilities, and procedures during tower crane erection and dismantling. Read the full DOSH Hazard Alert: Roles, responsibilities, and procedures during the erection and dismantling of tower cranes.

The hazard alert was issued in response to an April 27, 2019 incident where a construction tower crane collapsed in Seattle, Washington while being dismantled, fatally injuring two workers and two members of the public.

Violations Result in Fines

The Department of Labor and Industries completed it’s investigation in October 2019. During the investigation, it was found that the conditions leading up to the collapse may not have been an isolated event, but was due to procedures that have been practiced throughout the industry.

The state issued citations to: GLY Construction, Northwest Tower Crane Service, and Morrow Equipment, totaling over $107,000.00. The state did not cite two other companies involved, Omega Morgan and Seaburg Construction.

New Safety Regulations – DOSH Directive 8.55

On November 4, 2019, DOSH issued Directive, 8.55 – Tower Crane Erection and Dismantling Violations which clarified the rules for the erection and dismantling of tower cranes, and established a willful penalty classification for specific tower crane erection/dismantling safety violations.

The April 2019 accident, which was found to have been “totally avoidable,” prompted the state to craft and implement the new regulations outlined in Directive 8.55.

This directive includes enforcement instructions for Compliance Officers who inspect tower cranes worksites to ensure employers provide an assembly/disassembly director and follow the manufacturer’s written procedures when erecting and dismantling tower cranes. Directive 8.55 also creates a willful violation classification, allowing for increased penalties in cases where safety is compromised.

WAC 296-155-53402 sets out the rules for safety practices when assembling and disassembling a crane/derrick.

Tower crane erection and dismantling presents safety hazards.

When the DOSH Compliance Crane Unit documents violations of either WAC 296-155-53402 (1) or WAC 296-155-53402 (17)(a) through (d) on a tower crane erection or dismantling site, the violation will be classified as willful and the penalty will be multiplied by 10.
