Seasonal conditions create slip and trip hazards that change throughout the year. In winter, ice and frost make every surface treacherous. In autumn, wet leaves create a slippery film on paths and platforms. Year-round, mud from earthworks and rain coats walkways and access routes. These hazards are predictable and preventable through daily assessment, gritting, cleaning, and providing appropriate footwear. Seasonal slip injuries account for a significant proportion of all construction site injuries each year.
Key Hazards
Slips and falls on black ice that is invisible on dark tarmac and concrete
Loss of footing on wet leaves covering walkways, ramps, and platform surfaces
Falls on thick mud coating access routes from earthworks and rain saturation
Vehicle skidding on icy or muddy site roads causing collisions and loss of control
Control Measures
Assess ground conditions at the start of every shift and treat icy surfaces with grit before work begins.
Clear wet leaves from walkways, ramps, and scaffold platforms daily during autumn months.
Install raised boardwalks or temporary matting over persistently muddy access routes.
Provide boot-wash stations at the entrance to buildings and welfare facilities.
Ensure all workers wear safety footwear with good tread depth suitable for the prevailing conditions.
Grit and salt pedestrian routes and vehicle roads before the first arrivals on frosty mornings.
Use anti-slip treads on temporary ramps and stairways during wet and icy weather.
Report any areas where mud, ice, or leaves accumulate and create persistent hazards.
Adjust the traffic management plan to account for reduced vehicle traction on muddy or icy routes.
Remember
Black ice is invisible and is most dangerous in shaded areas and on north-facing surfaces.
Wet leaves on walking surfaces are as slippery as ice and must be cleared daily in autumn.
Persistent mud on access routes must be managed with boardwalks, matting, or regular maintenance.
Grit and salt must be applied before the workforce arrives, not after the first person has slipped.
Good tread on safety footwear is essential but does not eliminate the risk on ice and wet leaves.
Seasonal slip hazards are entirely predictable and preventable with daily assessment and action.
