1

Acclimation

An individual's gradual process of becoming accustomed to an environment

2

Accommidation

The efforts to alter or adjust the environment, worker relationship, or task to reduce injury potential

3

Active Cooling

The process of using external methods or devices to reduce elevated body core temperatures

4

Atypically Stressful Incident

An incident that involves an unusually gruesome situation, serious firefighter injury, firefighter death, or other potential psychological stress

5

Circadian Rhythm

A person's physiological response to the 24 hour clock, which includes sleep, energy peaks, and necessary body functions

6

Ergonomics

The science of adapting work or working conditions to a worker and the study of problems associated with people adjusting to their work environment

7

Passive Cooling

The use of shade, air movement, and rest to bring down core temperatures

8

Transient Heat Fatigue

An early warning sign that the core temperature is elevated, as characterized by the onset of physical exhaustion that is remedied by rest and hydration only to return quickly and more profoundly upon engagement with the hot environment

9

Work Hardening

Efforts to improve an individual's strength, flexibility, and aerobics to help prevent overexertion at incidents

10

Reading Firefighters Concept

Observation of firefighters and predicting when they will make a mistake, exercise poor judgment, and overextend their abilities

11

Overexertion

Number one cause of injuries and deaths in the fire service, often leading to mistakes in judgment or decreased mental awareness

12

Ergonomic Stressors

Related to the physical setting, the relationship of the worker to the setting, and the task requirements

13

Heat Stress Injuries

Progressively get worse as a body core temperature rises.

14

Heat Stress Concept

ISO's should presume that firefighters working in full PPE and SCBA have elevated core temperatures. The remedy is active cooling through cold/wet towels on head and neck, or forearm cooling.

15

Cold Stress Injuries

Typically frostnip or frostbite

16

Cell Performance

Optimal cell performance is required for arduous firefighting tasks. Cells require oxygen, water, and fuel (glucose)

17

Heat Exposure Concept

Firefighters can lose a quart of water an hour through sweating, breathing, and cell waste removal. Hydration of 4-8oz for every 20 minutes of physical labor is paramount to prevent dehydration

18

Food Choices

Should include a balance of 40% low glycemic carbs, 30% protein, and 30% dietary fat

19

REHAB Acronym

R - Rest
E - Energy nutrition
H - Hydration
A - Accommodation for weather conditions
B - BLS medical monitoring (ALS recommended)

20

Rehab Scaling

Can be scaled as self-rehab for short duration/small incidents, or as formal rehab when the call is large enough

21

Rehab Concept

All members performing rehab must be familiar with signs and symptoms of heat fatigue and other related conditions
