What?

  • Road marking application involves painting lines, symbols, and text onto carriageway surfaces using specialist marking equipment.
  • Working in live or recently closed carriageways exposes marking operatives to struck-by risk from passing vehicles.
  • Traffic management must be installed and confirmed before any operative enters the carriageway for marking operations.
  • Thermoplastic road marking material is applied at temperatures between 180°C and 220°C — contact causes severe thermal burns.
  • Solvent-based paint markings release volatile organic compounds requiring ventilation awareness for enclosed application areas.
  • Reflective glass beads are broadcast onto wet markings — the beads are a slip hazard on hard surfaces when spilled.
  • Pre-formed thermoplastic markings are applied using propane torches, creating hot works and LPG handling hazards.
  • Marking vehicles moving slowly along the carriageway require high-visibility livery and amber flashing beacons.
  • Night marking operations require enhanced lighting of the work area without creating glare for approaching drivers.
  • All road marking operatives must hold valid highway works competency qualifications for the operations they carry out.

Why?

Traffic exposureRoad marking happens in or adjacent to live traffic — operatives are struck by vehicles that do not see them or slow down.
Thermal burnsThermoplastic material at 200°C causes instant full-thickness burns — thermal PPE and careful handling are mandatory.
Slow-moving targetMarking vehicles move at walking speed in live carriageways — drivers approaching from behind may not react in time.
Do Don't
  • Ensure traffic management is installed before entering the carriageway for marking.
  • Wear thermal PPE including gloves and boots when handling hot thermoplastic material.
  • Hold valid highway works qualifications before carrying out road marking operations.
  • Use marking vehicles with high-visibility livery and amber flashing beacons.
  • Clean up spilled glass beads promptly — they create a severe slip hazard.
  • Follow hot works procedures when using propane torches for pre-formed markings.
  • Wear Class 3 high-visibility clothing at all times during road marking operations.
  • Provide adequate lighting for night marking without creating glare for drivers.
  • Ventilate enclosed areas when using solvent-based marking paints.
  • Brief the team on the traffic management layout and emergency procedures daily.
  • DON'T enter the carriageway for marking without confirmed traffic management in place.
  • DON'T handle thermoplastic material without thermal PPE — it burns at over 180°C.
  • DON'T carry out road marking without the required highway competency qualifications.
  • DON'T use marking vehicles without high-visibility livery and flashing amber beacons.
  • DON'T leave spilled glass beads on surfaces — they cause dangerous slipping.
  • DON'T use propane torches without following hot works and LPG safety procedures.
  • DON'T work in live carriageways without Class 3 high-visibility clothing.
  • DON'T create glare for approaching drivers with poorly positioned work area lighting.
  • DON'T use solvent-based paints in enclosed or poorly ventilated locations.
  • DON'T skip the daily briefing on traffic management and emergency procedures.
