ATOMIC
Examine blast areas to determine amounts and kinds of explosive charges needed and to ensure that safety laws are observed.
ATOMIC
Tie specified lengths of delaying fuses into patterns in order to time sequences of explosions.
ATOMIC
Place safety cones around blast areas to alert other workers of danger zones, and signal workers as necessary to ensure that they clear blast sites prior to explosions.
ATOMIC
Place explosive charges in holes or other spots; then detonate explosives to demolish structures or to loosen, remove, or displace earth, rock, or other materials.
ATOMIC
Insert, pack, and pour explosives, such as dynamite, ammonium nitrate, black powder, or slurries into blast holes; then shovel drill cuttings, admit water into boreholes, and tamp material to compact charges.
ATOMIC
Mark patterns, locations, and depths of charge holes for drilling, and issue drilling instructions.
ATOMIC
Compile and keep gun and explosives records in compliance with local and federal laws.
ATOMIC
Measure depths of drilled blast holes, using weighted tape measures.
ATOMIC
Connect electrical wire to primers, and cover charges or fill blast holes with clay, drill chips, sand, or other material.
ATOMIC
Lay primacord between rows of charged blast holes, and tie cord into main lines to form blast patterns.
ATOMIC
Assemble and position equipment, explosives, and blasting caps in holes at specified depths, or load perforating guns or torpedoes with explosives.
ATOMIC
Verify detonation of charges by observing control panels, or by listening for the sounds of blasts.
ATOMIC
Move and store inventories of explosives, loaded perforating guns, and other materials, according to established safety procedures.
ATOMIC
Light fuses, drop detonating devices into wells or boreholes, or activate firing devices with plungers, dials, or buttons, in order to set off single or multiple blasts.
ATOMIC
Drive trucks to transport explosives and blasting equipment to blasting sites.
ATOMIC
Cut specified lengths of primacord and attach primers to cord ends.
ATOMIC
Maintain inventory levels, ordering new supplies as necessary.
ATOMIC
Repair and service blasting, shooting, and automotive equipment, and electrical wiring and instruments, using hand tools.
ATOMIC
Set up and operate short-wave radio or field telephone equipment to transmit and receive blast information.
ATOMIC
Insert waterproof sealers, bullets, and/or powder charges into guns, and screw gun ports back into place.
ATOMIC
Clean, gauge, and lubricate gun ports.
ATOMIC
Lower perforating guns into wells, using hoists; then use measuring devices and instrument panels to position guns in correct positions for taking samples.
ATOMIC
Create and lay out designs for drill and blast patterns.
ATOMIC
Document geological formations encountered during work.
ATOMIC
Operate machines to flush earth cuttings or to blow dust from holes.
ATOMIC
Set up and operate equipment such as hoists, jackhammers, and drills, in order to bore charge holes.
