Chapter 8: How Fire Fighting Affects the Body
Heat stress is a common problem in fire fighting; what two ways can you reduce your risk for heat stress?
On-scene rehabilitation and physical fitness

Physical fitness and wearing less clothing under your PPE
What serious heat related illnesses can heat stress lead to?
Heat rash and heat stroke
Heat exhaustion and heat stroke

How much fluid can a fire fighter lose through sweating in an hour?
0.5 liter (0.5 quart)
2 liters (2.11 quarts)
2.5 liters (2.63 quarts)
1 liter (1.05 quarts)
Rehydration rate should equal:
Greater than loss rate so you can store liquid and work longer
Depends on how much you drank prior to the incident response
Loss rate, which means up to 2 liters per hour
Less than loss rate to avoid feeling full
What results in cardio-vascular strain, cognitive impairment and poor performance?
Physical fitness resulting in more heat tolerance
High blood volume resulting in heart stress
High core temperature resulting in heat stress
High caloric intact resulting in digestive stress
What is the objective of active cooling?
Decrease core temperature
Increase blood volume
Decrease blood volume
Increase core temperature
In addition to opening gear and taking off hood, what are some steps that can be taken to provide active cooling?
Water, wet towels and use of fans
Locate an air conditioned building close to the scene to use during periods of rest
Remove boots and place feet into an ice bath
