Winter weather introduces a new layer of risk to an already demanding industry. While construction professionals are no strangers to unpredictable conditions, cold temperatures, snow, and ice can significantly increase hazards on the jobsite. Slips and falls, reduced dexterity from frozen fingers, equipment malfunctions, and limited visibility are just a few of the challenges crews face during the colder months.
These seasonal risks don’t replace the everyday dangers of construction, such as operating heavy machinery, working at heights, or navigating constantly changing job conditions — they add to them. That’s why maintaining a heightened awareness of safety practices becomes even more critical as temperatures drop.
To help keep crews protected throughout the winter season, we’ve compiled seven essential cold-weather safety tips every construction professional should follow when working in cold conditions.
Monitor Weather Forecasts
Weather conditions can change quickly, making jobsites and commutes unsafe. Monitor forecasts regularly and plan ahead so crews have time to secure the jobsite and leave before severe weather hits. When conditions allow work to continue, stay alert for signs of hypothermia, wear proper cold-weather gear, and take breaks as needed.
Stay Hydrated
Hydration is just as important in cold weather, even if you don’t feel thirsty. Physical labor causes fluid loss, and proper hydration helps maintain alertness, circulation, and body temperature. Water is best, but warm, non-caffeinated drinks like herbal tea or cider can help. Avoid alcohol and caffeine, which can contribute to dehydration.
Provide a Heated Area for Breaks
Frequent breaks and access to a heated trailer, tent, or indoor space help workers stay warm and conserve energy. When heated areas aren’t available, limit exposure time and provide warm beverages. Always follow safety guidelines when using heaters, including securing them properly and keeping them away from combustible materials.
Wear Proper PPE
Cold-weather PPE is essential, but bulky gear can introduce new hazards like limited visibility, restricted movement, or fogged eyewear. Choose winter PPE that balances warmth with mobility and task requirements. Taking time to select the right equipment helps ensure both comfort and safety on the job.
Ensure Equipment is Ready for Cold
Cold temperatures can damage equipment if it isn’t properly prepared. Before winter, confirm fluids are rated for low temperatures and cab heaters are functioning. During cold weather, remove snow and ice, protect exposed equipment, and allow machines time to warm up to proper operating temperatures to prevent unnecessary wear and repairs.
Remove Snow and Ice
Clear snow and ice and apply salt or traction materials before work begins. Avoid working on rooftops, scaffolding, ladders, and elevated surfaces after snowfall whenever possible. Mark and restrict access to areas where ice cannot be removed, and use proper lifting techniques during snow removal to reduce injury risk.
Educate Workers on Frostbite and Hypothermia
It is important to make education on the symptoms of frostbite and hypothermia part of your safety trainings. Things like shivering, clumsiness, and slurred speech are all signs of hypothermia and should trigger an emergency response as soon as they are identified. By having a basic understanding of the signs and symptoms, workers can receive immediate medical attention, which improves long-term risks. If you are concerned that somebody is exhibiting signs of frostbite or hypothermia, get help immediately.
