Extreme heat during fire operations requires additional ____ due to exertion.

Extreme heat during fire operations necessitates additional manpower due to the physical demands placed on firefighters. The intense heat increases the risk of heat stress and fatigue, requiring more personnel to ensure that tasks are completed safely and efficiently. An increased number of firefighters allows for better rotation during operations, ensuring that individuals can rest and recover from the heat while maintaining continued effectiveness in tackling the situation.

While equipment, water, and supplies are indeed important factors during firefighting, they do not directly address the increased need for human resources to handle the physical toll of high temperatures on firefighters. The focus on manpower is essential for maintaining safety protocols and ensuring that operations can continue without compromising the health of the crew under extreme conditions.
