Understanding Safety Risks: Incidents
Incidents involving work or equipment regulated by the Safety Standards Act are required to be reported to the appropriate safety manager. We investigate many of these incidents to gain an understanding of safety hazards in British Columbia and determine what actions can be taken to manage them.
Explanation of incidents
Technical Safety BC completes investigations on certain incidents reported to us in all technologies except for rail. We investigate incidents reported to us when:
- Regulated work or regulated equipment is involved
- Evidence is available to help determine causes and contributing factors.
- A learning opportunity exists to understand and document what caused the incident, and to inform prevention of similar incidents.
Learnings from incidents
While the number of reported incidents decreased by 9.5% in 2020, some trends were found in the 171 investigations that were completed. We found the following:
1. Carbon monoxide is still the silent killer
In the summer of 2020, Technical Safety BC responded to carbon monoxide (CO) incidents in Ruby Lake and Tulameen which resulted in three fatalities and one injury. These investigations documented instances of both slow and rapid onset carbon monoxide exposures and demonstrate the hazards associated with some do-it-yourself (DIY) work.
These incidents illuminate some of the challenges of regulating DIY activity and the importance of obtaining proper permits. To help address this, we rolled out an extensive public safety education and awareness campaign to help educate British Columbians about the hazards of CO.
2. Passenger behaviour on amusement devices is a factor
Looking at Amusement Devices and Passenger Ropeways, we found passenger behaviour or passenger error to be the cause in most incidents. In our analysis of closed incidents related to ziplines, 75% of the incidents were due to passenger error and behaviour. For chairlifts and magic carpets on the ski hills, 32 incidents were passenger-related.
3. Leaks make up a large percentage of boiler, pressure vessel, and refrigeration incidents
Of 15 closed incidents, 10 involved an ammonia release or a boiler leak. For more information on these incidents, visit our Boiler, Pressure Vessel, and Refrigeration technology page.
