Which of the following is considered a life-threatening environmental emergency?

Heat stroke is considered a life-threatening environmental emergency because it occurs when the body overheats due to prolonged exposure to high temperatures, often in combination with dehydration. This condition disrupts the body’s ability to regulate its temperature, leading to hyperthermia, which can damage vital organs and even result in death if not treated promptly. Symptoms include confusion, seizures, and unconsciousness, indicating a severe state that requires immediate medical attention.

While hypothermia and frostbite are also serious conditions resulting from exposure to cold, they may not be recognized as life-threatening in the same immediate sense that heat stroke is. Sunburn, while it can be painful and have long-term effects on skin health, is not classified as a life-threatening emergency. Understanding the severity and implications of heat stroke is crucial for effective response in emergency situations.
