450. In case of a storm or blizzard in the area where an electrically-fired blast is being prepared on the surface, within a shaft or an adit, and if electrical detonators and detonating relays have been placed in or connected to loaded or partially loaded holes, the blasting area shall be evacuated by all workers who might be exposed to the risk of an accident in case of a premature explosion caused by lightning or a blizzard. The unused detonators and detonating relays shall be returned to the explosives magazine, and access to the blasting area shall be guarded until there is no further risk of a storm or blizzard.
