Summary
A framer was framing walls on the third level of a three-storey single-family dwelling. He was working beside an uncovered stair opening with no guardrail. The stair openings for the second and third levels were vertically aligned. The stairways had not yet been constructed, so there was a drop of 18.5 feet from the third level to the first-level basement concrete floor. The framer fell through the successive openings to the concrete floor below. He was taken to hospital but later died of his injuries.

Conclusions

Findings as to causes

• The framer fell over the unguarded edge of an open stairwell. He fell 18.5 feet from the third level to the basement. There were no fall protection measures in place.

• The framing company's culture of expedient production likely led the company to ignore fundamental safe work practices and the high hazard of falls. Supervision for the framing company did not include ensuring that fall prevention systems were in place and that workers followed safe work procedures.
• The prime contractor did not ensure, through inspections of known high hazards, that work was being conducted safely on the worksite.
