13.3 Prevention strategies for environmental emergencies

Heat and cold can be dangerous. Knowing how to prevent emergencies is key. From acclimatization to proper clothing, these strategies help our bodies handle extreme temperatures safely.

Monitoring conditions, using the buddy system, and protecting against sun exposure are crucial. By understanding and applying these prevention methods, we can enjoy outdoor activities while minimizing risks.

• Acclimatization involves gradually exposing the body to hot environments over a period of time (usually 7-14 days) to allow physiological adaptations that improve heat tolerance
• Proper hydration means consuming adequate fluids before, during, and after exposure to hot environments to maintain fluid balance and prevent dehydration
• Appropriate clothing for hot environments should be lightweight, loose-fitting, and light-colored to facilitate heat dissipation and protect against sun exposure (wide-brimmed hats, long-sleeved shirts)

Monitoring Environmental Conditions

• WBGT (Wet Bulb Globe Temperature) is a composite temperature used to estimate the effect of temperature, humidity, wind speed, and solar radiation on the human body
• WBGT takes into account the cooling effect of evaporation from a wet bulb thermometer, the heat from direct sunlight measured by a black globe thermometer, and ambient air temperature
• Rest periods should be scheduled based on environmental conditions (WBGT), work intensity, and individual factors to allow the body to cool down and prevent heat stress

Prevention Strategies for Cold-Related Emergencies

Assessing Cold Stress Factors

• Wind chill factor is the perceived decrease in air temperature felt by the body on exposed skin due to the flow of air, which accelerates heat loss from the body
• Wind chill factor is determined by air temperature and wind speed, with higher wind speeds resulting in lower wind chill temperatures and increased risk of cold stress
• Appropriate clothing for cold environments should be layered, insulating, and wind/water-resistant to trap heat, wick away moisture, and protect against wind and precipitation (thermal underwear, fleece, waterproof outer layer)

Implementing Safety Measures

• Buddy system involves working in pairs to monitor each other for signs and symptoms of cold stress (shivering, confusion, slurred speech) and provide assistance if needed
• Buddies should take frequent breaks together in warm, sheltered areas to allow the body to warm up and prevent further heat loss

General Prevention Strategies

Protecting Against Sun Exposure

• Sun protection measures include wearing protective clothing (wide-brimmed hats, long-sleeved shirts), applying broad-spectrum sunscreen (SPF 30 or higher), and seeking shade during peak sun hours (10 am to 4 pm)
• Proper hydration is essential in both hot and cold environments to maintain fluid balance, regulate body temperature, and support physical performance
• Consuming water, electrolyte beverages, and other non-caffeinated fluids regularly throughout the day can help prevent dehydration and heat-related illnesses

Promoting Safety Through Teamwork

• Appropriate clothing selection should consider the specific environmental conditions, activity level, and individual factors (age, health status) to ensure adequate protection and comfort
• Clothing should be adjusted as needed based on changing conditions (adding or removing layers) to maintain a comfortable body temperature and prevent overheating or overcooling
• Buddy system is an important safety measure in both hot and cold environments to ensure that individuals look out for each other, recognize signs of distress, and provide prompt assistance if needed
• Buddies should be familiar with emergency procedures and have means to communicate with each other and summon help if necessary (whistles, two-way radios)
