What?

  • Ice and snow on construction sites cause slips, vehicle skids, and plant overturns every winter.
  • Gritting walkways, access roads, and working platforms is the primary control for ice-related injuries.
  • Rock salt and grit must be spread before ice forms, typically in the evening or early morning.
  • Snow must be cleared from scaffolds, access platforms, and stairways before work can resume safely.
  • Compacted snow turns to ice and becomes more dangerous than fresh snowfall on walking surfaces.
  • Plant operations on icy haul roads require reduced speed and increased following distances.
  • Scaffold boards, ladder rungs, and platform surfaces become extremely slippery when frozen.
  • Emergency grit supplies should be stockpiled on site before winter weather arrives.
  • The Workplace (Health, Safety and Welfare) Regulations 1992 require walking surfaces to be safe in all conditions.
  • A winter weather action plan should define trigger temperatures and responsibilities for gritting.

Why?

Prevent slip injuriesSlips on ice are one of the most common winter injuries on construction sites, causing fractures and head injuries.
Vehicle safetyPlant and vehicles operating on icy haul roads skid, overturn, and collide, causing fatal crush injuries.
Legal dutyThe Workplace Regulations 1992 require employers to maintain safe walking surfaces, including treating ice and clearing snow.
Do Don't
  • Spread grit on walkways, access roads, and working platforms before ice forms.
  • Clear snow from scaffolds, stairways, and platforms before resuming work.
  • Stockpile grit supplies on site before the winter season begins.
  • Implement the winter weather action plan when temperatures drop below 3°C.
  • Reduce vehicle and plant speeds on haul roads when conditions are icy.
  • Inspect scaffolds, ladders, and access equipment for ice before first use each day.
  • Assign specific personnel the responsibility for gritting and snow clearance.
  • Remove compacted snow and ice before it bonds to the walking surface.
  • Wear boots with good tread and grip suited to winter walking conditions.
  • Monitor weather forecasts and prepare gritting teams for overnight frost events.
  • DON'T assume gritting once is enough; reapply after rain, thaw, and refreeze.
  • DON'T walk on scaffolds, ladders, or platforms without checking for ice first.
  • DON'T drive plant at normal speed on icy or snow-covered haul roads.
  • DON'T wait until someone slips before starting the gritting programme.
  • DON'T leave compacted snow to turn into ice on walkways and access routes.
  • DON'T use hot water to clear ice; it refreezes and creates a worse hazard.
  • DON'T ignore early morning ice on site; it is the most dangerous time.
  • DON'T climb ladders or scaffolds that have ice on the rungs or boards.
  • DON'T store grit supplies where they cannot be quickly accessed when needed.
  • DON'T forget to grit emergency escape routes and muster point areas.
