||Explosives Workers, Ordnance Handling Experts, and Blasters
- Tie specified lengths of delaying fuses into patterns in order to time sequences of explosions.
- 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.
- 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.
- Connect electrical wire to primers, and cover charges or fill blast holes with clay, drill chips, sand, or other material.
- Lay primacord between rows of charged blast holes, and tie cord into main lines to form blast patterns.
- Assemble and position equipment, explosives, and blasting caps in holes at specified depths, or load perforating guns or torpedoes with explosives.
- 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.
- Cut specified lengths of primacord and attach primers to cord ends.
- Connect gun chambers to electric detonating devices, and operate controls at panelboards, in order to detonate charges in guns or to ignite chemical charges.
- Insert powder charges into chambers of sidewall sample-taking cylinders, and assemble cylinders, using special wrenches.
