Would we consider a lesser distance than 100 m? What is included in the definition of electric power lines (generators, 110 and 220 lines)?
Many blasters’ licences are restricted to electric means of initiation only and unfortunately about 90% of blasting is done within 100 m of power lines. Some non-electric means of initiation are quite new, therefore some powderman may have to undergo retraining. The wording in 77-1 was “a safe distance”. After a review of the requirement it has been decided, in the interest of safety, that the restriction should be applied at 100 m as stated. The definition of a power line does not include 110 and 220 wiring in a building, or a generator, but refers only to high-tension power lines such as those running between hydro poles along city streets.
167(3) A powderman shall ensure that electric initiation of blasting is not used
(b) when blasting within 100 m of electric power lines
