The City requires that blasting companies are insured and that they issue notification to neighbouring property owners.
The blasting company must provide notification to the occupants of all buildings within 300 metres of the site that includes:
- a description of the work being undertaken
- dates and duration of the work
- methods to safeguard persons and property
- signals and warning methods
- blasting company contact
- insurance company contact
If a Blasting Company and/or Developer removes soil and/or rock off site that exceeds 200 cubic meters, a Blasting Permit and Soil Deposit Permit are required.
Blasting is regulated by WorkSafeBC
WorkSafeBC oversees blasting work practices in British Columbia. They are responsible for issuing Blasting Tickets to qualified individuals and ensuring safe blasting practices.
WorkSafeBC considers proper blasting notification as follows:
- 12 short audible whistle signals followed by a 2 minute pause;
- Blast will be detonated;
- A longer whistle signal to indicate 'All Clear' after detonation.
Hours of Blasting
- Monday through Thursday: 8:30 a.m. to 4:00 p.m.
- Friday only: 8:30 a.m. to 3:00 p.m.
- Saturdays, Sundays, & Statutory Holidays: No Blasting Permit
Where explosives are employed within sixty (60) metres of any building, bridge, dam, or other structure the holder of the permit must retain an independent insurance adjuster, at the permit holder’s cost, to complete a pre-blast survey. The survey shall itemize the condition of each surveyed structure existing prior to detonation and shall be supported by photos.
