By law, an employer is required to notify the Workplace Safety and Health (WSH) Branch of a serious incident by the fastest means of communication available. Serious Incident Alerts include descriptions of the actual serious incidents reported to WSH Branch and are provided to raise awareness and initiate preventative actions as appropriate.
The following four incidents occurred on Manitoba construction projects in June 2022:
- While hoisting a Tyndall Stone weighing approximately 200 kg, the clamp released and the stone fell 60 feet. No workers were injured.
To review best practices for rigging for hoisting and craning, read our toolbox talk.
- There was structural collapse from a large portion of a building under construction, which was blown down overnight. No workers were on site.
While there were no injuries, it is critical to investigate such incidents to prevent future injuries.
- A worker was on a ladder installing trusses when a worker below passed a nailer, accidentally triggering the tool.
The nailer fired into the worker's abdomen.
Nail guns are very powerful and can be very dangerous — review best practices for your jobsite.
- A jobsite was flooded 12 feet due to excavation. No workers were injured.
Excavations pose flood risk, especially if the site is below the water table/exposed to adverse weather. It's critical to have an emergency plan in place.
