Injury Type : Close call
Core Activity : Concrete reinforcing
Location : Lower Mainland
ID Number : 2007117080199
Date of Incident : 2007-Jun

A worker was tensioning a post-tension strand and stressed the cable to 3,000 psi. A problem with the anchor was suspected. The supplier's representative was called to the site before any other tensioning was allowed to proceed. The representative decided to continue to tension the strand to 6,000 psi. As a worker was removing the tensioning jack, the anchor failed, causing a piece of concrete to fly off. A similar incident had occurred earlier at another project involving the same batch of anchors. These post-tensioning anchors, known as Batch 27, had been manufactured exclusively for Harris P/T, a division of Harris Steel. Subsequent testing had found Batch 27 anchors were defective and they were supposed to be removed from distribution. Apparently one of the defective anchors had been delivered to this site and was the anchor that failed.

Core Activity : Scaffold dismantling
Location : BC
ID Number : 2007155260053
Date of Incident : 2007-Mar

While dismantling a scaffold, a worker on the scaffold lost his footing where two planks overlapped. As he fell forward, he grabbed a guardrail to stop his fall, but the guardrail separated from the scaffold and the worker fell 14 feet to the concrete surface below. The tubular steel guardrail was attached at one end to a J-hook on a walk-through end frame. The guardrail was too long for the span, so the other end had been secured to the next end frame using wire. When the worker grabbed the guardrail, it rolled out of the J-hook, broke the wired connection, and fell to the ground. The investigation revealed that even if both ends of the guardrail had been supported by J-hooks, the possibility of roll-out was not prevented. WorkSafeBC's engineering section has informed the scaffold manufacturer of this problem.
