Detonation is normally contained within the plastic tubing. However, burns may occur if the shock tube is held. Five MDI blasting caps are available which replace the M6 electric and M7 Non-electric blasting cap. A red flag is attached 1 meter from the blasting cap and a yellow flag 2 meters from the blasting cap. May be initiated utilizing fuse igniter or match.
Yellow bands indicate calibrated one minute time intervals.
Burn time will increase with altitude and colder temperatures. Each blasting cap has delay elements to allow for staged detonations. Used as a relay device to transmit a shock tube detonation impulse from an initiator to a high strength blasting cap. Low strength blasting caps cannot reliably set off explosives. They should only be used to set off additional shock tubes.
