Objective

To educate workers on the hazards of cold weather, including hypothermia and frostbite, and to provide methods for prevention and protection.

Introduction

Working in cold environments presents unique hazards that can lead to serious health issues. This toolbox talk will cover how to recognize and prevent cold-related illnesses and injuries.

Key Points

• Dress in Layers: Wear multiple layers of loose-fitting clothing to trap warm air and provide insulation. Layers allow you to adjust to changing temperatures and activity levels. [6]
• Stay Dry: Wet clothing significantly reduces insulation and increases the risk of hypothermia. Change wet clothes immediately. [8]
• Buddy System: Work in pairs so you and a coworker can monitor each other for signs of cold stress. [1]
• Warm Beverages and Food: Drink warm, sweet beverages and eat high-calorie foods to maintain energy and body heat. Avoid caffeine and alcohol. [1]
• Take Breaks: Take frequent breaks in a heated area to warm up and allow your body to recover. [1]
• Know the Symptoms: Be aware of the early signs of hypothermia and frostbite in yourself and others.

Hazard Identification

• Hypothermia: Uncontrolled shivering, fatigue, loss of coordination, confusion, slowed pulse and breathing, loss of consciousness, and potentially death. [1] [5]
• Frostbite: Numbness, tingling, aching, bluish or pale skin, tissue damage, and potential amputation. [5] [5]
• Slips and Falls: Injuries from slips on ice, snow, or wet surfaces. [2]
• Carbon Monoxide Poisoning: Headaches, dizziness, weakness, vomiting, chest pain, confusion, and potentially death.

Control Measures

• Wear appropriate cold weather clothing.: Dress in layers, including a moisture-wicking base layer, an insulating middle layer, and a windproof and waterproof outer layer. [1]
• Use the buddy system.: Monitor coworkers for signs of cold stress and ensure they take breaks to warm up. [1]
• Take frequent breaks in a warm area.: Provide a heated shelter or warming station where workers can take breaks to warm up. [1]
• Stay hydrated with warm, sweet beverages.: Drink warm, non-caffeinated, and non-alcoholic beverages to maintain body temperature and energy levels. [1]
• Clear walkways of ice and snow.: Use sand, salt, or other de-icing materials to prevent slips and falls. [2]
• Ensure proper ventilation when using fuel-fired heaters.: Use indirect-fired heaters and monitor carbon monoxide levels regularly. [2]
• Avoid exhaustion and fatigue.: Energy is needed to keep muscles warm. [8]

Personal Protective Equipment (PPE) Requirements

• Insulated Gloves: Wear insulated gloves to protect hands from cold temperatures and prevent frostbite. Ensure gloves are waterproof if working in wet conditions. [2]
• Warm Hat: Wear a hat or other head covering to prevent heat loss from the head. [1]
• Insulated, Waterproof Boots: Wear insulated and waterproof boots to keep feet warm and dry. Ensure boots fit properly to maintain circulation. [1]
• Face and Eye Protection: Use face masks, scarves, or neck tubes to protect the face from wind and cold. Wear appropriate eyewear to protect against glare and blowing snow. [4]
• Moisture-Wicking Socks: Wear socks made of wool, polypropylene, or other moisture-wicking materials to keep feet dry and warm. [6]

Real-World Example or Case Study

Ron, a construction worker, forgot his gloves and hat one winter day. He started shivering and had trouble holding his tools. He was suffering from hypothermia. This could have been prevented by wearing appropriate clothing. [1]

Group Discussion

Discuss the following questions:

1. What are some additional ways to protect yourself from cold weather hazards on this job site?
2. Have you ever experienced a cold-related injury or illness? What did you learn from it?
3. What are the specific areas on our site where cold weather hazards are most prevalent?

Emergency Procedures

1. Move the person to a warm, dry area. [7]
2. Remove wet clothing and replace with dry clothing or blankets. [7]
3. For hypothermia, warm the center of the body first. [7]
4. Give warm, sweet drinks if the person is conscious. [7]
5. Seek immediate medical attention. [7]
6. For frostbite, immerse the affected area in warm (not hot) water. [7]
7. Do not rub the affected area. [7]
8. If no pulse, begin CPR. [7]
9. Call for emergency help (ambulance or 911). [9]

Questions and Answers

• Q: What is wind chill and how does it affect me?

A: Wind chill is the perceived decrease in air temperature felt by the body due to the flow of air. It can significantly increase the risk of frostbite and hypothermia.

• Q: How can I prevent slips and falls on ice?

A: Wear slip-resistant footwear, use handrails, and take small, deliberate steps.

• Q: What should I do if I see a coworker exhibiting signs of hypothermia?

A: Move them to a warm area, remove wet clothing, provide warm beverages (if conscious), and seek medical attention immediately.

Summary

Recap of main points:

• Dress in layers to stay warm and dry. [3]
• Use the buddy system to monitor each other for signs of cold stress. [3]
• Take frequent breaks in a warm area.
• Know the symptoms of hypothermia and frostbite and how to respond.

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