Cold Weather Operations
The Problem
Winter conditions present unique challenges to workplace safety. Exposure to extreme cold, icy surfaces, and equipment malfunctions can lead to serious injuries such as hypothermia, frostbite, slips, or even equipment failure. Today, we’ll focus on identifying these hazards and implementing practical solutions to keep everyone safe during cold weather operations.
Identify the Hazards
- Cold Stress: Prolonged exposure to low temperatures can result in hypothermia or frostbite.
- Slips, Trips, and Falls: Ice and snow significantly increase the risk of incidents.
- Equipment Failures: Machinery may malfunction or be damaged in cold conditions.
- Reduced Visibility: Snow, fog, or frost can impair visibility and increase accident risk.
- Carbon Monoxide Exposure: Portable heaters or equipment used in enclosed spaces without adequate ventilation can be hazardous.
Safety Practices and Preventative Measures
Personal Protective Equipment (PPE):
- Dress in three layers:
- Base layer: Moisture-wicking fabric like wool or synthetics.
- Middle layer: Insulating layer (e.g., fleece or wool).
- Outer layer: Waterproof and windproof jacket or shell.
- Use insulated safety boots with slip-resistant soles, thermal gloves, face protection, and high-visibility winter clothing.
Monitoring Exposure:
- Follow CCOHS recommendations on safe exposure times and work/rest cycles based on wind chill.
- Use the buddy system to observe symptoms of cold stress.
- Regularly monitor weather conditions and adjust tasks accordingly.
Warming Break Areas:
- Provide heated shelters for rest breaks (ideally between 18–24°C).
- Supply warm drinks and emergency items like blankets and first aid kits.
- Encourage scheduled warming breaks, especially in freezing conditions.
Equipment Maintenance:
- Use winter-grade oils and antifreeze.
- Protect water lines and equipment from freezing temperatures.
- Cover or store machinery when not in use.
Managing Ice and Snow Hazards:
- Apply grit or de-icer to walking surfaces before ice forms.
- Assign designated staff for snow and ice removal duties.
- Maintain proper tools and equipment for winter maintenance.
Vehicle Readiness:
- Check fluids, batteries, and tyre tread daily.
- Use snow chains or winter tyres where applicable.
- Keep emergency kits, scrapers, and flashlights in each vehicle.
- Drive slower and increase following distances in icy conditions.
Real-Life Case or Scenario
Last winter, a worker suffered frostbite on their fingertips while using metal tools outdoors. They were not wearing proper thermal gloves and had not taken warming breaks. With the right PPE and regular breaks, this incident could have been avoided.
Employee Responsibilities
- Wear suitable winter PPE and follow cold weather guidelines.
- Look out for signs of cold stress in yourself and others.
- Take warming breaks as advised and report unsafe conditions.
Employer Responsibilities
- Provide PPE appropriate for cold and wet conditions.
- Ensure heated shelters and warm drink stations are available.
- Monitor weather forecasts and adjust work plans accordingly.
- Train staff on cold stress risks and first aid procedures.

Let’s commit to keeping warm, being prepared, and working safely this winter. Starting today, inspect your PPE, take regular breaks in heated areas, and report any hazards immediately.
Wrap-Up
Cold weather safety is about more than comfort—it’s about preventing injuries and keeping each other safe. By planning ahead and using proper gear and procedures, we can work through winter safely and effectively. Thank you for your attention.
Standards Overview
CCOHS requires that workers exposed to cold environments are provided with suitable PPE.
Employers must assess environmental conditions and implement controls to prevent cold stress.
Workers must be trained to identify and respond to hypothermia, frostbite, and related hazards.
