Winter site inspections: What to look for

Safety on site is essential, whatever the time of year. During winter, there are extra hazards to be aware of.

Snow, ice, and freezing temperatures can make work more difficult, while shorter days and poor weather can reduce visibility.

Keeping your site safe in winter doesn’t need to be complicated.

Here’s a guide to help you carry out winter building site inspections effectively.

THE IMPORTANCE OF SITE INSPECTIONS IN WINTER

Regular site inspections and risk assessments should be carried out all year round. During winter, they become even more critical.

Additional hazards include snow, ice, fog, heavy rain, and shorter daylight hours. Without identifying these seasonal risks and putting controls in place, your site could quickly become unsafe.

Without properly identifying these seasonal hazards and mitigating against them, your site could quickly become unsafe.

WHAT TO LOOK FOR IN A WINTER SITE INSPECTION

Here’s a winter checklist to help you keep your site safe throughout the colder months.

VISIBILITY

Shorter days and darker mornings and evenings mean visibility is a key concern.

Make sure you:

• Replace damaged bulbs in outdoor lighting
• Consider additional lighting, such as tower lights
• Reassess hi-vis clothing to ensure it meets the correct class for winter site safety and compliance with UK hi-vis regulations

HARSH WEATHER

Cold temperatures, rain, and ice increase the risk of slips, falls, and cold-related illnesses.

Ways to reduce risk:

• Create warm break-out areas so staff can take breaks out of the cold
• Monitor the weather forecast to adjust work schedules during extreme conditions
• Implement anti-slip measures, such as anti-slip safety boots and keep grit fully stocked
• Monitor workers for signs of cold stress, frostbite, or hypothermia and respond immediately
• Provide cold-weather PPE, including insulated hi-vis jackets, gloves, and waterproof footwear

Cold-weather PPE should support other controls and not replace them.

*Slip-resistant footwear can reduce the risk of slipping but cannot prevent slips entirely. Black ice and compacted ice may still be hazardous.

EMERGENCIES

Expect the unexpected in winter conditions. Prepare for emergencies so you can respond quickly.

Make sure that you:

• Keep first aid stations fully stocked
• Train workers on winter-specific emergency procedures
• Ensure all walkways, stairways, and access points are clear of ice and snow
• Update response plans for winter-specific scenarios, such as working in snow or icy conditions

WINTER SITE EQUIPMENT

Cold temperatures affect more than people; they can also impact machinery and equipment.

You should always:

• Swap to winter-grade oils and set fuel and hydraulic fluids to recommended levels
• Check batteries, vehicles, and machinery for issues caused by cold
• Cold can cause metals to reach their ductile-to-brittle transition temperature, increasing the risk of breaks or failure
• Regularly inspect and service all equipment to maintain safety and performance

Follow PUWER and LOLER guidance when inspecting and using site equipment.

COMMUNICATION

Inspections and controls only work if your team knows about them.

Ensure that you:

• Place visible signs and safety messages around your site for seasonal precautions
• Delegate tasks clearly. For example, who replenishes grit? Who monitors the weather forecast?
• Encourage open communication so workers can report unsafe conditions and provide feedback
