Objective

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

Introduction

Working in hot weather can lead to serious health issues like heat stroke, heat exhaustion, heat cramps, and heat rash. It's important to know how to protect yourself and your coworkers. [1]

Key Points

• Stay Hydrated: Drink plenty of water throughout the day. Aim for about 1 cup (8 ounces) every 15-20 minutes during moderate work in the heat. 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 cool down. [1]
• Recognize the Signs of Heat Illness: Be aware of the symptoms of heat exhaustion and heat stroke in yourself and others. Symptoms of heat exhaustion include headache, nausea, dizziness, heavy sweating, and weakness. Heat stroke symptoms include confusion, hot, dry skin or profuse sweating, slurred speech, and unconsciousness. [1]
• Wear Appropriate Clothing: Wear lightweight, light-colored, and loose-fitting clothing to help your body stay cool. [4]
• Acclimatize to the Heat: Gradually increase your exposure to hot conditions over a period of 7-14 days to allow your body to adjust. New workers should start with 20% of the workload on the first day, increasing by no more than 20% each subsequent day. [5]
• Buddy System: Use a buddy system to monitor each other for signs and symptoms of heat illness. [7]

Hazard Identification

Working in hot weather presents several hazards that can lead to heat-related illnesses and injuries.

• Heat Stroke: Can lead to organ damage, brain damage, and death. [4]
• Heat Exhaustion: Can cause dizziness, nausea, weakness, and can progress to heat stroke if not treated. [8]
• Dehydration: Reduces the body's ability to cool itself, leading to increased risk of heat illness. [5]
• Burns from Hot Surfaces: Contact with hot equipment or materials can cause burns. [1]
• Increased Risk of Other Injuries: Sweaty palms, fogged-up safety glasses, and dizziness can increase the risk of accidents. [1]

Control Measures

• Provide Cool Drinking Water: Ensure that cool drinking water is readily available and encourage workers to drink frequently, about 1 cup every 15-20 minutes. [5]
• Provide Shade or Cooling Areas: Offer shaded areas or air-conditioned spaces where workers can take breaks and cool down. [3]
• Modify Work Schedules: Schedule physically demanding tasks for cooler parts of the day, such as early morning or late afternoon. [5]
• Implement a Buddy System: Pair workers to monitor each other for signs of heat stress and ensure they are taking breaks and staying hydrated. [5]
• Acclimatization: Gradually increase workers' exposure to heat over 7-14 days, starting with a reduced workload and increasing it incrementally. [7]
• Ventilation: Improve ventilation in indoor workplaces using fans, air conditioning, or by opening windows to allow for better airflow. [3]

Personal Protective Equipment (PPE) Requirements

• Light-Colored, Loose-Fitting Clothing: Wear light-colored, loose-fitting clothing to reflect heat and allow for better airflow. [4]
• Wide-Brimmed Hats: Wear wide-brimmed hats to provide shade and protect your head and face from direct sunlight. [5]
• UV-Protective Sunglasses: Use UV-protective sunglasses to shield your eyes from harmful UV rays, which can be more intense in hot, sunny conditions. [1]

Real-World Example or Case Study

Ben, a bricklayer, was working outside in extremely hot temperatures for several hours. 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, ensuring Ben received prompt medical attention. [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 additional ways we can stay safe while working in hot weather?
3. What steps can we take to improve our worksite to prevent heat-related illnesses?

Emergency Procedures

1. If a coworker shows signs of heat exhaustion, move them to a cool, shaded area. [1]
2. Provide them with cool water to drink, if they are conscious. [4]
3. If symptoms worsen or they show signs of heat stroke (confusion, seizures, unconsciousness), call 911 immediately. [2]

Questions and Answers

Here are some common questions about working in hot weather:

• Q: How much water should I drink in a day when working in the heat?

A: You should aim to drink about 1 cup (8 ounces) of water every 15-20 minutes. [1]

• Q: What are the first signs of heat exhaustion?

A: The first signs include headache, nausea, dizziness, heavy sweating, and weakness. [1]

• Q: What should I do if I start feeling dizzy or nauseous while working in the heat?

A: Stop working immediately, move to a cool, shaded area, drink water, and inform your supervisor or a coworker. [1]

Summary

Recap of main points:

• Stay hydrated by drinking plenty of water throughout the day. [1]
• Take frequent breaks in shaded or air-conditioned areas to cool down. [1]
• Recognize the signs and symptoms of heat-related illnesses in yourself and your coworkers. [1]
• Wear appropriate clothing, including lightweight, light-colored, and loose-fitting garments. [4]

Action Items

Specific actions participants should take:

1. Familiarize yourself with the company's heat illness prevention plan. [1]
2. Report any signs or symptoms of heat illness to your supervisor immediately. [6]

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