Detonators
29.A.10 Blasts using electric detonators must be fired with an electric blasting machine or a properly designed power source.
Electronic Detonators
- Blasts using non-electric detonators must be fired by a blasting machine or starting device prescribed by the manufacturer.
- When blasting near radar or radio transmission facilities or near electrical energy sources where testing has shown that RF energy or stray electrical current may present a hazard to electrical blasting, an approved non-electrical initiation system must be employed.
- When electric detonators are used, leg wires must be short circuited (shunted) until connected into the circuit for firing.
29.A.11 Detonating cord must be initiated by non-electric detonator (cap and fuse), electric detonator, shock tube detonator or gas initiated detonator in accordance with the manufacturer's recommendation.
29.A.12 Delay electric detonators, non-electric delay detonators, detonating cord connectors, or sequential blasting machines must be used for all delayed blasts; the practice must conform to the manufacturer's recommendations.
