Preventing Heat-related Illnesses at Work

During the hot summer months, outdoor employees are increasingly vulnerable to heat-related illnesses. Normally, the body has ways of keeping itself cool by allowing heat to escape through the skin and evaporating sweat. However, if the body does not cool down properly or enough, a person may suffer a heat-related illness.

Here are the three main types of heat-related illnesses:

⦁ Heat cramps are muscular pains and spasms caused by heavy exertion. This is generally the result of a loss of water and salt through sweating.

⦁ Heat exhaustion is caused by fluid loss and decreased blood flow to the vital organs. This condition can produce flu-like symptoms.

⦁ Heatstroke is the most serious heat-related illness and occurs when the body’s internal cooling system has failed. This is a life-threatening condition requiring immediate action.

If you work outdoors this summer, it’s important to follow the proper precautions to avoid heat-related illnesses. Consider these simple steps to keep yourself cool and safe:

⦁ Wear loose, light-colored clothing and some type of hat.

⦁ Be conscious of warm conditions, especially when performing strenuous tasks.

⦁ Take breaks in the shade when possible.

⦁ Avoid overexertion during peak temperature hours, especially midday.

⦁ Drink plenty of water, even if you don’t feel thirsty.

⦁ Stay away from drinks that contain caffeine, as they can dehydrate you.

Employers can play a critical role in preventing heat-related illnesses among their employees, particularly those working in hot environments or outdoors. Here are several strategies employers can implement to help protect their workers:

Training and Education

• Awareness Programs: Educate employees about the risks of heat-related illnesses and the importance of staying hydrated and recognizing early symptoms.

• First Aid Training: Provide training on how to respond to heat-related emergencies, including recognizing signs of heat exhaustion and heat stroke.

Hydration and Rest Breaks

• Water Stations: Ensure easy access to cool drinking water. Encourage employees to drink water frequently, even if they are not thirsty.

• Scheduled Breaks: Implement regular breaks in shaded or cool areas, especially during peak heat times.

• Hydration Reminders: Use alarms or reminders to prompt employees to drink water regularly.

Environmental Controls

• Shaded Areas: Provide shaded or air-conditioned rest areas.

• Ventilation and Cooling Systems: Use fans, ventilation systems, or air conditioning to cool work areas, particularly indoors.

• Heat Mitigation: Schedule heavy tasks during cooler parts of the day and rotate job functions to minimize heat exposure.

Personal Protective Equipment (PPE)

• Cooling Vests: Provide cooling vests or other cooling PPE.

• Lightweight Clothing: Encourage the use of lightweight, breathable clothing.

• Hats and Sunscreen: Provide wide-brimmed hats and sunscreen for outdoor workers.

Acclimatization Programs

• Gradual Exposure: Implement acclimatization programs for new and returning workers to gradually increase their exposure to heat over a period of 7-14 days.

• Monitoring: Closely monitor new employees and those returning from extended leave during the acclimatization period.

Health Monitoring

• Buddy System: Implement a buddy system where employees watch out for signs of heat stress in their coworkers.

• Health Checks: Conduct regular health checks to monitor workers for symptoms of heat-related illnesses.

• Reporting Systems: Establish a system for employees to report symptoms of heat stress without fear of reprisal.

Workplace Policies and Plans

• Heat Illness Prevention Plan: Develop and implement a comprehensive heat illness prevention plan.

• Emergency Response Plan: Have an emergency response plan in place for heat-related illnesses, including steps for immediate first aid and when to call emergency services.

Adjusting Work Schedules

• Shift Work: Schedule work during cooler parts of the day, such as early morning or late evening.

• Flexible Schedules: Offer flexible work schedules to avoid the hottest parts of the day.

• Job Rotation: Rotate employees between hot and cool tasks to minimize exposure time.

By taking these proactive steps, employers can significantly reduce the risk of heat-related illnesses and create a safer, healthier work environment.
