| 1. | Examine blast areas to determine amounts and kinds of explosive charges needed and to ensure that safety laws are observed. |
| 2. | Tie specified lengths of delaying fuses into patterns in order to time sequences of explosions. |
| 3. | 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. |
| 4. | 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. |
| 5. | 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. |
| 6. | Mark patterns, locations, and depths of charge holes for drilling, and issue drilling instructions. |
| 7. | Compile and keep gun and explosives records in compliance with local and federal laws. |
| 8. | Measure depths of drilled blast holes, using weighted tape measures. |
| 9. | Connect electrical wire to primers, and cover charges or fill blast holes with clay, drill chips, sand, or other material. |
| 10. | Lay primacord between rows of charged blast holes, and tie cord into main lines to form blast patterns. |
| 11. | Assemble and position equipment, explosives, and blasting caps in holes at specified depths, or load perforating guns or torpedoes with explosives. |
| 12. | Verify detonation of charges by observing control panels, or by listening for the sounds of blasts. |
| 13. | Move and store inventories of explosives, loaded perforating guns, and other materials, according to established safety procedures. |
| 14. | 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. |
| 15. | Drive trucks to transport explosives and blasting equipment to blasting sites. |
| 16. | Cut specified lengths of primacord and attach primers to cord ends. |
| 17. | Maintain inventory levels, ordering new supplies as necessary. |
| 18. | Set up and operate equipment such as hoists, jackhammers, or drills, in order to bore charge holes. |
| 19. | Repair and service blasting, shooting, and automotive equipment, and electrical wiring and instruments, using hand tools. |
| 20. | Set up and operate short-wave radio or field telephone equipment to transmit and receive blast information. |
| 21. | Insert waterproof sealers, bullets, and/or powder charges into guns, and screw gun ports back into place. |
| 22. | Clean, gauge, and lubricate gun ports. |
| 23. | Connect gun chambers to electric detonating devices, and operate controls at panelboards, in order to detonate charges in guns or to ignite chemical charges. |
| 24. | Lower perforating guns into wells, using hoists; then use measuring devices and instrument panels to position guns in correct positions for taking samples. |
| 25. | Insert powder charges into chambers of sidewall sample-taking cylinders, and assemble cylinders, using special wrenches. |
| 26. | Obtain samples of earth from sidewalls of well boreholes, using electrically exploding devices. |
| 27. | Signal hoist operators to lower torpedoes or sample-taking guns into wells and to raise equipment for sampling from blast holes after detonation. |
| 28. | Observe odometers, weight indicators, and instrument panels in trucks in order to position guns at predetermined points in wells. |
| 29. | Repair electrical instruments, using electricians' hand tools. |
