Objective

To understand the risks associated with working in cold weather and how to protect ourselves from cold-related injuries and illnesses.

Introduction

Working in cold weather presents unique challenges that can lead to serious health problems if precautions are not taken. This toolbox talk will cover the hazards of cold environments and the steps we can take to stay safe.

Key Points

• Dress in Layers: Wear clothing suitable for cold, wet, and windy conditions. Dressing in loose-fitting layers allows you to adapt to changing temperatures and trap body heat effectively. Silk, polypropylene, or lightweight wool should be worn next to the skin, with wool layers over undergarments. Outer garments should be wind and water-resistant, such as nylon. [1] [3] [3] [3]
  • Inner layer: Moisture-wicking fabrics
  • Middle layer: Insulation (wool, fleece)
  • Outer layer: Windproof and waterproof
• Buddy System: Work in pairs so that you and your coworker can spot danger signs in each other. Hypothermia and frostbite can impair judgment, making it difficult to recognize symptoms in yourself. [1] [3]
• Stay Hydrated and Nourished: Drink plenty of warm, sweet beverages (sugar water, sports drinks) to maintain energy levels and body temperature. Avoid caffeine (in coffee, tea, sodas, or hot chocolate) and alcohol, as they can increase the risk of dehydration and hypothermia. [1]
• Take Frequent Breaks: Take breaks often, in a heated area, to warm up. This helps prevent your body temperature from dropping to dangerous levels. Heated shelters (tents, cabins, rest rooms, etc) should be made available nearby. [1] [5]
• Know Your Risks: Be aware that you are at higher risk if you take certain medications, are in poor physical condition, or suffer from illnesses such as diabetes, hypertension, or cardiovascular disease. Certain medications and health conditions can impair the body's ability to regulate temperature. [1]
• Adjust Work Pace: Adjust the pace or rate of work so that it is not too high and cause heavy sweating that will result in wet clothing. Sweating can lead to rapid cooling and increase the risk of hypothermia. [5]

Hazard Identification

• Hypothermia: Uncontrolled shivering, fatigue, loss of coordination, confusion, and potentially death. [1] [2]
• Frostbite: Numbness, tingling, aching, bluish or pale, waxy skin, and potential tissue damage leading to amputation. [2] [2]
• Trench Foot: Damage to the feet from prolonged exposure to wet and cold conditions. [1]
• Slips, Trips, and Falls: Injuries due to ice and snow accumulation. [7]
• Increased Risk of Heart and Respiratory Issues: Exposure to cold temperatures can exacerbate existing conditions. [6]
• Windburn: Skin damage due to exposure to wind and cold. [6]

Control Measures

• Provide Heated Shelters: Ensure heated shelters are available for workers to take breaks and warm up. Do not use unvented portable gas heaters in indoor settings as it can lead to harmful levels of carbon monoxide and other harmful combustion products and is a fire hazard. [4] [4]
• Implement a Buddy System: Workers should monitor each other for signs of cold stress, such as shivering, confusion, or fatigue. [5]
• Weather Monitoring: Use weather surveillance procedures to identify upcoming cold events and to detect the sudden onset of cold events. [4]
• Emergency Plans: Have emergency plans and procedures in place to respond to extreme cold events. [4]
• Adjust Work Schedules: Reschedule work performed outdoors when temperatures are milder. [4]
• Improve Heating in Work Areas: Ensure adequate heating in indoor work areas. [4]

Personal Protective Equipment (PPE) Requirements

• Insulated Gloves: Wear insulated gloves to protect your hands from the cold. Ensure gloves are waterproof if working in wet conditions. Inspect gloves regularly for tears or damage.
• Warm Hat: Always wear a hat to prevent heat loss from your head. A large amount of body heat can be lost through the head if it is not covered. [3]
• Waterproof Boots: Wear waterproof and insulated boots to keep your feet warm and dry. Ensure boots have good traction to prevent slips on ice or snow. [3]
  • Check for adequate tread
  • Ensure proper fit to allow for warm socks
• Protective Outerwear: Wear a windproof and waterproof coat or jacket to protect against the elements. Ensure the outerwear provides adequate insulation. [3]

Group Discussion

Discuss the following questions:

1. What are some additional ways we can protect ourselves from the cold on this job site?
2. Have you ever experienced a cold-related injury or illness? What happened?
3. What are the signs and symptoms of hypothermia and frostbite that we should be aware of?

Emergency Procedures

1. Request immediate medical assistance. [2]
2. Move the victim into a warm room or shelter. [2]
3. Remove wet clothing. [2]
4. Warm the center of their body first chest, neck, head, and groin-using an electric blanket; or use skin-to-skin contact under loose, dry layers of blankets, clothing, or towels. [2]

Summary

Recap of main points:

• Dress in layers to stay warm and dry.
• Use the buddy system to monitor each other for signs of cold stress.
• Take frequent breaks in heated areas to warm up.
• Stay hydrated and avoid caffeine and alcohol.

Report all hazards, near-misses, and incidents to your supervisor immediately.
