Cold Arctic air across the UK is leading to widespread hard frosts and some of the coldest sub-zero temperatures so far this winter.

While snow cumulations are often the most disruptive, for the construction industry it’s equally important to address the increased risks posed by freezing temperatures and icy conditions on-site. Preparation is key to ensuring safety and productivity during the winter months so read this week’s blog for some critical information and tips.

Key hazards to look out for

Working outdoors in freezing weather can expose workers to several hazards, including:

  • Slippery surfaces: Ice-covered pathways, scaffolds, and platforms can lead to slips, trips and falls, one of the most common causes of workplace injuries.
  • Cold stress: Prolonged exposure to low temperatures can cause conditions like hypothermia and frostbite, affecting worker health and performance.
  • Unstable ground conditions: Frost can weaken soil and create uneven surfaces, making footing and equipment operation hazardous.
  • Tool and machinery issues: Cold weather can affect the functionality of tools and vehicles, increasing the likelihood of malfunctions.

Three-point plan for cold weather safety

To minimise risks associated with icy and freezing conditions, employers and workers must implement proactive measures. Here’s our suggested three-point plan:

1. Prepare the site

  • Regularly grit walkways, site entrances and access points to reduce slip hazards. Keep these areas clear of ice buildup.
  • As the cold can impact the performance of tools and machinery, conduct regular inspections to ensure they are functioning properly. Consider using materials suited to lower temperatures.
  • Reduced daylight hours can make icy patches harder to spot so take time to ensure all work areas have adequate lighting to avoid accidents.
  • Regularly inspect the ground for frost-related instability, particularly in areas that are supporting heavy machinery.

2. Protect workers

  • Alongside regular PPE, workers should be encouraged to wear multiple layers for insulation, topped with waterproof outer layers. Thermal gloves, socks, and insulated boots with slip-resistant soles are essential.
  • Cold weather often suppresses thirst, but staying hydrated is crucial. Warm drinks and high-energy meals can help workers maintain energy levels.
  • Schedule regular breaks in heated welfare facilities to allow workers to warm up and recover.
  • Pair up workers to monitor each other for signs of cold stress, such as shivering, fatigue or confusion. This system ensures help is readily available if someone’s health is at risk (see more on health risks below).

3. Adapt work practices

  • Adjust work schedules to limit exposure during the coldest parts of the day and prioritise tasks that can be performed safely in current conditions.
  • Ensure all workers receive training so they understand the risks associated with cold weather and know how to mitigate them, including recognising early signs of cold stress.

Health risks and prevention

Prolonged exposure to cold and icy conditions can lead to serious health issues, including:

  • Cold stress: Symptoms include shivering, numbness and fatigue. Severe cases can lead to confusion, slowed breathing or even unconsciousness. Workers should immediately seek warmth and medical attention if symptoms worsen.
  • Frostbite: Affects extremities like fingers and toes, causing numbness, discoloration, and tissue damage. Prevent it by wearing insulated gloves and footwear.
  • Hypothermia: This is a life-threatening condition where the body temperature falls too low to function properly. Early symptoms include uncontrollable shivering, pale skin, blue or grey lips, shallow breathing and confusion. Hypothermia requires urgent medical attention so, if you suspect a colleague is experiencing symptoms, call emergency services immediately. Prevention involves dressing appropriately and limiting time in freezing environments.

Staying safe together

Working in cold and icy conditions presents unique challenges for the construction sector, but with proper planning, training and precautions, these risks can be managed effectively. By recognising the hazards and preparing accordingly, workers and managers can reduce health-related issues and maintain safety across the site.

Leadership plays a critical role in ensuring these measures are effectively implemented and followed so prioritise safety, monitor conditions and make sure everyone looks out for each other. Help your construction teams navigate the winter months with confidence.
