How to Keep Outdoor Crews Safe in Cold Weather
Winter does not stop outdoor work. Construction crews, snow removal teams, delivery drivers, utility workers, landscapers doing winter cleanup and parking attendants all work in conditions that can cause serious harm. Cold stress, including hypothermia, frostbite and trench foot, is preventable with planning and supervision.
OSHA's cold stress guidance is the core reference for US employers. Here is how to put it into practice for a small crew.
Know the Risks
- Hypothermia: body temperature drops dangerously. Early signs include shivering, fatigue, confusion and clumsiness.
- Frostbite: freezing of skin and tissue, often fingers, toes, ears and nose. Skin may look pale, waxy or numb.
- Trench foot: injury from prolonged wet and cold feet, even above freezing.
- Slips and falls on ice, which cause many winter injuries.
Wind and wet conditions make cold far more dangerous than the thermometer suggests.
Plan the Work
- Check the forecast, including wind chill, before each shift
- Schedule the hardest work for the warmest part of the day where possible
- Plan shorter work periods in extreme cold
- Have a warm shelter or vehicle available for breaks
- Never let anyone work alone in severe conditions without a check-in plan
Clothing and Equipment
- Layers: a moisture-wicking base, an insulating middle and a waterproof outer layer
- Insulated, waterproof boots with good grip
- Hat, gloves and face protection
- Spare dry socks and gloves
- Traction devices for icy surfaces where appropriate
Breaks, Warmth and Water
- Regular warm-up breaks in a heated space
- Warm drinks and water; dehydration still happens in the cold
- Food for energy
- Change out of wet clothing quickly
Acclimatise and Watch New Workers
New workers and those returning from time off are at higher risk. Ease them in and pair them with experienced crew members.
Train Supervisors and Crews
- How to recognise early signs in themselves and others
- What to do if someone shows symptoms: get them warm, remove wet clothing, seek medical help
- When to stop work
- How to call for emergency help from the site
Buddy System
Pair workers to watch each other for warning signs. People with early hypothermia often do not notice their own confusion.
Vehicles
- Winter-ready vehicles: tyres, fluids, scrapers
- Emergency kits: blankets, water, phone charger, shovel
- Clear policy on driving in dangerous conditions

How MyTeamTasks Helps
In MyTeamTasks, a cold-weather pre-shift checklist can confirm the forecast was checked, equipment issued and the shelter available, with timestamped check-ins during the day for crews working in severe conditions. Supervisors can see from the dashboard that every crew completed its checks, and incidents are logged while details are fresh.
