BC SHIFTBOSS 419 CERTIFICATION
EVALUATION 2026 FULL QUESTIONS AND
CORRECT ANSWERS
◉ "What three methods may be used to destroy AN/FO explosives?"
Answer: "-By emptying the containers into a large body of stagnant
water
-By emptying them into a pit and pouring water of them
-By scattering them on the ground and then covering them with dirt.
◉ ""How is primacord destroyed?"""
Answer: The preferred method is by burning in the same manner as
dynamite. It must not be burned on the spool, but strung out in
parallel lines at least 1cm apart.
◉ "What is primacord?"
Answer: It is detonating cord consisting of high explosive core
contained in a waterproof textile covering.
◉ "What is the proper method of attaching a blasting cap to a line of
primacord?"
Answer: The cap is attached to the side of the primacord by means
of friction tape or other suitable material.
,◉ "What is a "Nonel" assembly?"
Answer: A plastic shock tube coated inside with finely powdered
explosive and securely crimped to a high strength (12 grain PETN)
non-electric delay detonator.
◉ "Can a "Nonel" cap be used to detonate all types of explosives that
are cap sensitive?"
Answer: Yes, the shock tube will not disturb any column of powder
as the shock tube does not explode.
◉ "How would you hook up "Nonel" caps?"
Answer: Hook up Nonel to a b-line trunk line pulling excess tubing
through the plastic connector, then attach a cap to b-line trunk line
and blast.
◉ "Would you trim off excess Nonel tubing?"
Answer: No, each Nonel is a sealed unit. One end of the tube is
sealed by means of heat seals, the other end by the detonator. If
excess tubing is cut off moisture may enter and cause malfunction.
◉ "Can Nonels be used in areas of possible stray current?"
Answer: Yes, Nonels are not a conductor of electricity.
,◉ "What is the recommended exposure time for a Nonel detonator
assembly in n explosive that uses fuel oil as a component?"
Answer: 6 days (15 days for Nonel XT)
◉ "How should a blasting cap be attached to a detonator cord such
as primacord?"
Answer: It should be taped into position and the end of the cap must
be positioned with the base of the cap pointing in the direction of
initiation.
◉ "How should a blasting cap be attached to a procore primer or
other high strength cast primer?"
Answer: The end of the cap should be positioned within the primer,
pointed in the direction of the main charge.
◉ "What is the detonation velocity of detonating cord?"
Answer: ~22,000f/s or 6,075m/s
◉ "Can detonating cord be lit with a match?"
Answer: Detonating cord cannot be lit with a match.
◉ "What is the chemical composition of the explosive used in
detonating cord?"
Answer: Pentaerythritol tetranitrate.
, ◉ "How is the explosive strength of detonating cord usually
expressed?"
Answer: In grams of PETN per meter of foot of cord.
◉ "What is a detonating connector relay?"
Answer: A detonating connector relay is a nonelectric device which
provides a short interval delay in a detonation cord circuit. It is also
known as a delay connector, MS connector, or a relay.
◉ "How is a pigtail detonating connector attached to detonating
cord?"
Answer: By a square knot or by taping together, with 4 overlap."
◉ "What is the purpose of Nonel MS connectors?"
Answer: Nonel MS connectors are used with detonating cord to
provide millisecond delay intervals along a line of propagation.
◉ "How should detonating cord be cut?"
Answer: With a crimper, knife, or cord cuter on a slight angle and
with a pulling motion.
◉ "Why should newly cut ends of detonating cord be sealed?"
