Summary
Four workers were working on the relatively flat roof of a structural steel building. They were laying down metal roof panels over a layer of blanket insulation that had already been placed across the metal roof beams. One of the workers fell through the insulation to the concrete floor 17 feet (5.2 metres) below. The worker died in hospital from his injuries.

Conclusions

Findings as to causes

• The worker fell through a layer of insulation and hit the concrete floor 17 feet (5.2 metres) below. There was no fall protection system in place to stop his fall.

• Supervisors and workers did not have any written site-specific safe work procedures for installing the roofing panels.
• The employer did not adequately ensure that supervision at the work site complied with the site-safety program and WorkSafeBC requirements. There was no adequate system to ensure that the supervisors were trained to perform their safety responsibilities and were carrying them out.
