Objective

To understand the hazards of working in hot weather and how to prevent heat-related illnesses.

Introduction

Working in hot weather can lead to serious health problems, including heat stroke, heat exhaustion, heat cramps, and heat rash. It's crucial to understand these risks and take preventive measures to protect yourself and your coworkers. [1]

Key Points

• Stay Hydrated: Drink plenty of water throughout the day. During moderate work in the heat, drink about 1 cup (8 ounces) of water every 15–20 minutes. Avoid alcohol, caffeine, and sugary drinks, as they can dehydrate you. [1]
• Take Frequent Breaks: Take regular breaks in a shaded or air-conditioned area to allow your body to cool down. [1]
• Acclimatization: Gradually increase your exposure to hot environments over 7-14 days to allow your body to adjust. New workers and those returning from absences need more time to acclimatize. [4]
• Recognize the Signs of Heat Illness: Be aware of the symptoms of heat stroke and heat exhaustion in yourself and your coworkers. Early recognition and intervention can save lives. [1]
• Modify Work Schedules: When possible, adjust work schedules to avoid the hottest parts of the day. Consider starting earlier or later to minimize heat exposure. [3]

Hazard Identification

• Heat Stroke: Medical emergency, potentially fatal. Symptoms include confusion, loss of consciousness, seizures, very high body temperature, and hot, dry skin or profuse sweating. [5]
• Heat Exhaustion: Can lead to heat stroke if not treated. Symptoms include headache, nausea, dizziness, weakness, irritability, thirst, heavy sweating, and elevated body temperature. [5]
• Heat Cramps: Painful muscle spasms, usually in the abdomen, arms, or legs. [10]
• Dehydration: Reduced physical and mental performance, increased risk of heat-related illnesses. [8]
• Burns: Contact with hot surfaces or steam can cause burns. [1]

Control Measures

• Provide Adequate Ventilation: Ensure adequate air movement, especially in indoor environments, to facilitate cooling. [9]
• Use Cooling Aids: Provide cooling fans, air conditioning, or cooling vests to help workers stay cool. [6]
• Implement a Buddy System: Encourage workers to monitor each other for signs of heat illness. [7]
• Provide Shade: Offer shaded areas for breaks and work when possible to reduce direct sun exposure. [3]
• Acclimatization Program: Implement a program to gradually increase workers' exposure to heat over time. [3]
• Monitor Weather Conditions: Stay informed about weather forecasts and heat advisories to anticipate and prepare for hot weather. [3]

Personal Protective Equipment (PPE) Requirements

• Light-Colored, Loose-Fitting Clothing: Wear light-colored, loose-fitting clothing to reflect heat and allow for better air circulation. [6]
• Wide-Brimmed Hat: Wear a wide-brimmed hat to protect your head and face from direct sunlight. [6]
• UV-Protective Sunglasses: Protect your eyes from harmful UV rays with sunglasses. [1]
• Sunscreen: Apply sunscreen with a high SPF to protect exposed skin from sunburn. [5]

Real-World Example or Case Study

Ben, a bricklayer, was working outside in extremely hot temperatures. He started feeling nauseated, had a headache, and was sweating heavily. His supervisor noticed he was working slower than usual and recognized the symptoms of heat illness. The supervisor called 911, moved Ben to the shade, gave him a cool drink, and wetted him with cool water and ice. Ben recovered thanks to quick recognition and action. [1]

Group Discussion

Discuss the following questions:

1. Have you or someone you know ever experienced a heat-related illness on the job? What happened?
2. What are some ways we can improve our worksite to prevent heat-related illnesses?
3. What are your personal strategies for staying cool and hydrated during hot weather?

Emergency Procedures

1. If a coworker shows signs of heat exhaustion, move them to a cool, shaded area. [1]
2. Provide cool water to drink. [1]
3. If a coworker shows signs of heat stroke, call 911 immediately. [2]
4. Cool the worker down by wetting them with cool water and fanning them. [2]

Questions and Answers

• Q: What are the early signs of heat stress?

A: Early signs include headache, dizziness, heavy sweating, weakness, and muscle cramps.

• Q: How often should I drink water in hot weather?

A: You should drink about 1 cup (8 ounces) of water every 15-20 minutes during moderate work in the heat. [1]

Summary

Recap of main points:

• Stay hydrated by drinking plenty of water throughout the day. [1]
• Take frequent breaks in a shaded or air-conditioned area. [1]
• Recognize the signs of heat stroke and heat exhaustion in yourself and coworkers. [1]
• Wear appropriate PPE, including light-colored clothing, hats, and sunscreen. [6]

Action Items

Specific actions participants should take:

1. Familiarize yourself with the company's heat illness prevention plan.
2. Monitor yourself and your coworkers for signs of heat stress.
3. Report any heat-related concerns to your supervisor immediately.

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