Asphalt plants combine heat, heavy moving machinery, fuel, dust and traffic. Most accidents happen during cleaning, maintenance and unblocking — when someone reaches into equipment that is still live, or enters a space without isolation. This checklist covers the main hazards. Always follow your local safety regulations and the plant manual.

Main hazards and controls

Hazard Where Key controls
Burns Bitumen tanks and lines, hot mix, drum, ducts Insulation, guards, heat-resistant PPE, procedures for hot work
Entanglement and crushing Conveyors, elevators, screens, mixer, drum drive Guards, emergency stops, lock-out/tag-out
Confined spaces Drum, mixer, silos, baghouse, tanks Permit system, isolation, atmosphere testing, standby person
Fire and explosion Fuel storage, burner, bitumen, coal dust, baghouse Fuel handling rules, interlocks, extinguishers, no ignition sources
Vehicle traffic Loaders, trucks, tankers One-way layout, separated walkways, spotters, reversing alarms
Falls Tower, silos, baghouse roof Handrails, harnesses, safe ladders
Dust and fumes Baghouse work, loading, bitumen Ventilation, respirators
Noise Burner, fan, screen Hearing protection, signage
Electrical Cabinets, cables Qualified electricians, closed cabinets, earthing

Lock-out/tag-out — the most important rule

Before anyone works on or inside equipment:

  1. Stop the equipment through normal controls
  2. Isolate every energy source: electrical, fuel, compressed air, hydraulic
  3. Apply a personal lock and tag to each isolation point
  4. Release stored energy: let drums and conveyors come to rest; vent air
  5. Test that the equipment cannot start
  6. Only the person who applied the lock removes it

Daily safety checklist

  • Guards in place on all drives, belts and rotating parts
  • Emergency stops and pull cords tested
  • Walkways clear; handrails secure
  • Fire extinguishers in place and charged
  • No fuel or bitumen leaks
  • Truck and loader routes clear; spotters where needed
  • PPE worn by everyone on site
  • Work permits issued for confined space, hot work and work at height

Site rules

  • One-way truck route; loaders and trucks never share a lane
  • Pedestrians use marked walkways only
  • No one under suspended loads or near the mixer discharge while loading
  • Bitumen tanker unloading supervised and bunded
  • Visitors escorted

Emergency preparedness

  • Written emergency procedure posted in the control room
  • First-aid kit and trained first-aiders; burn treatment training
  • Clear access for emergency vehicles
  • Regular fire drills

Safety training is part of our commissioning and operator training. For the maintenance tasks that need isolation, see the maintenance checklist.
