Structural PPE Safety and Training
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 wearing less clothing under your PPE
Physical fitness and wearing less clothing under your PPE
On-scene rehabilitation and physical fitness
Physical fitness and removing the liner from your structural fire fighting coat and pant to reduce the weight
What serious heat related illnesses can heat stress lead to?
Heat rash and heat exhaustion
Heat exhaustion and heat stroke
Heat rash and heat stroke
Heat cramps and heat rash
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:
Loss rate, which means up to 2 liters per hour
Less than loss rate to avoid feeling full
Greater than loss rate so you can store liquid and work longer
Depends on how much you drank prior to the incident response
What results in cardio-vascular strain, cognitive impairment and poor performance?
High caloric intact resulting in digestive stress
High core temperature resulting in heat stress
Physical fitness resulting in more heat tolerance
High blood volume resulting in heart 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?
Remove helmet and pour a pail of cool water over your head
Locate an air conditioned building close to the scene to use during periods of rest
Water, wet towels and use of fans
Remove boots and place feet into an ice bath
Medical monitoring is checking your vital signs as well as:
Checking for signs of dehydration and rehydration
Checking for signs of hypogonadism and hypergonadism
Checking for signs of hypoglycemia and hypothyroidism
Checking for signs of hyperthermia and hypothermia
Physical fitness can increase your blood volume, which helps combat heat stress, by:
20% in 10 days
10% in 10 days
20% in 20 days
