The physical and mental demands associated with firefighting and other emergency operations exceed those of virtually any other occupation. When you combine the inherent stresses of handling emergency incidents with the environmental dangers of extreme heat and humidity or extreme cold, you create conditions that can have an adverse impact on the safety and health of the individual emergency responder. When emergency responders become fatigued, their ability to operate safely is impaired. As a result, their reaction time is reduced and their ability to make critical decisions diminishes. This book examines the need for rehab operations at emergency scenes and defines the concept of emergency incident rehabilitation with a review of the historical pattern of firefighter injuries and deaths associated with the stresses of emergency operations.
