As fatigue increases, the risk of injury:

As fatigue increases, the risk of injury increases due to several factors that diminish a person's physical and mental abilities. When firefighters or emergency responders are tired, their reaction times slow down, coordination becomes impaired, and decision-making skills can suffer. These changes can lead to mistakes in judgment, improper handling of tools or equipment, and an overall inability to respond effectively to emergency situations.

Moreover, physical fatigue can result in reduced strength and endurance, making it more challenging to perform demanding tasks such as lifting, carrying, or maneuvering in dangerous environments. This heightened risk of injury is particularly significant in the demanding contexts in which firefighters operate, where the consequences of fatigue can be severely detrimental both to their safety and the safety of others. Therefore, understanding and managing fatigue is crucial in maintaining operational readiness and minimizing the potential for injury during firefighting operations.
