Field-proven safety protocols for mining technicians. Master equipment diagnostics, confined-space repairs, high-voltage lockout, and emergency maintenance to keep critical assets running safely underground and on surface.
Zero-incident procedures for underground & surface mining maintenance.
Mining technicians service haul trucks, drills, and conveyors under MSHA Part 46/48 and OSHA 1910. Technicians are the last line of defense before equipment returns to production. Coordinate with supervisors using protocols from the Mining Industry Safety Supervisors Playbook and Forestry Industry Technicians Roadmap.
| Activity | Primary Hazard | Control Priority |
|---|---|---|
| High-Voltage Lockout | Electrocution | High |
| Confined-Space Entry | Toxic atmosphere | High |
| Haul-Truck Brakes | Runaway truck | High |
| Welding in Explosive Areas | Fire/explosion | Medium |
| Elevated Repairs | Fall from height | High |
Critical Alert: Proper LOTO & gas testing prevents 92% of technician fatalities—cross-checked in Logistics Industry Technicians Playbook.
Follow MSHA-approved steps for every repair—underground or surface—to eliminate energy hazards and toxic atmospheres, aligned with Waste Industry Operators Playbook.
Complete JSA, test atmosphere, verify permits, and don task-specific PPE. Establish exclusion zone.
Lock out ALL sources, bleed pressure, block raised components, and verify zero energy with meter.
Remove locks, test systems under load, clear area, and release equipment with signed tag. Verification in Ports & Rail Industry Technicians Guide.
MSHA mandates specific controls for high-risk mining systems—follow every step, with cross-references to Agriculture Industry Technicians Playbook.
Cage springs, chock wheels, and bleed air tanks before disassembly.
Install factory pins or certified blocks before working under raised bed.
Tag out auto systems and keep extinguisher in hand. Similar in Construction Industry Technicians Playbook.
Ground cables, wear arc-flash suit (Cat 4), and use insulated tools. Test for voltage twice.
Log every entry, maintain continuous ventilation, and keep rescue team on standby. Confined-space protocols in Oil & Gas Industry Technicians Guide.
MSHA requires daily inspection of all tools and PPE—document everything, with shared practices from Logistics Industry Technicians Playbook.
Check insulation on meters, secure air hoses, and verify torque wrench calibration. Tag defective tools.
Hard hat, safety glasses, steel-toe boots, flame-resistant clothing, hearing protection, and SCSR underground.
Use mechanical aids for loads over 50 lbs, team lift for batteries, and keep back straight.
Secure fire watch, blanket combustibles, and keep extinguisher within 10 ft. Hot-work permits required. Fire protocols in Waste Industry Safety Supervisors Roadmap.
This playbook has been authored, reviewed, and endorsed by certified technicians with decades of underground and surface experience.
"The high-voltage lockout checklist is perfect—saved my crew from a 4160 V shock last month."
"Confined-space entry steps match our mine rescue protocol exactly. Every tech should carry this."
"The haul-truck suspension block procedure is clear and visual—new techs learn it in 10 minutes."

Common questions from mining maintenance technicians about safe repair practices.
Use calibrated voltage tester, contact-to-ground, then ground-to-ground. Test tester on known live source before and after.
Any work on energized panels over 50 V. Match PPE to incident energy analysis on label (Cat 2–4 typical).
Test O₂, CO, H₂S, LEL. Ventilate continuously, wear harness, and keep attendant with radio. Log every entry.
Use OEM cylinder locks or MSHA-approved blocks. Never use wood or hydraulic pressure alone.
Red-tag unit, notify supervisor, and log in HVI app. MSHA protects your right to refuse unsafe work.
Inspect seal, pressure gauge, and mouthpiece every shift. Store in clean, accessible location.
Explore technician-focused safety resources across industries.
Comprehensive safety resources across all operational areas for mining fleet protection.
Use HVI's rugged tablets to access digital schematics, log LOTO, test atmospheres, and complete MSHA inspections—even 2,000 ft underground.
