What should be done immediately if a worker shows signs of heat exhaustion?

The immediate action of taking a worker showing signs of heat exhaustion to a cool place and providing fluids is important because it directly addresses the symptoms of heat exhaustion. Heat exhaustion occurs when the body becomes overly hot and can result in dehydration, fatigue, and weakness. By moving the worker to a cooler environment, the body can begin to recover from overheating, which is critical to preventing the condition from escalating into heat stroke, a far more severe and life-threatening condition.

Providing fluids is equally essential, as heat exhaustion often involves loss of fluids and electrolytes due to excessive sweating. By rehydrating the individual, there is a better chance to restore the body’s temperature regulation and overall function.

Other options present risks that could worsen the situation, such as encouraging the worker to continue their task, which could lead to a dangerous decline in their condition. Leaving them alone does not provide the immediate care needed, which could result in further complications. Suggesting a cold shower could lead to shock or further complications, as extreme changes in temperature might stress the body more. Thus, moving to a cool place and hydrating is the most effective and responsible response in this situation.
