Fitness, Work/Rest, Hydration, and Fatigue Management
What the exam tests
Fitness, Work/Rest, Hydration, and Fatigue Management tests whether you can sustain performance without becoming a liability. Questions focus on heat illness, hydration, fatigue signs, and the work/rest plan.
Core rules
- Fireline work is arduous; fitness includes aerobic capacity, strength, and heat acclimatization before assignment.
- Follow the incident work/rest schedule; fatigue reduces judgment, reaction time, and situational awareness. Rotate crews before errors appear.
- Drink small amounts frequently; use electrolytes when sweating heavily and working long shifts; avoid alcohol and excessive caffeine.
- Watch for heat illness: cramps, dizziness, headache, nausea, confusion. Confusion or collapse is an emergency-cool, shade, and get medical help.
- Sleep, food, and recovery are operational requirements, not perks.
Worked example
A crew member becomes quiet, stumbles, and stops sweating on a hot afternoon. The supervisor should not “push through” to finish the line. The member is moved to shade, cooled, and medically evaluated; the crew's work/rest and hydration plan is reassessed. The reasoning is that altered mental status and stopped sweating suggest serious heat illness, which can worsen rapidly.
Traps
Relying on thirst; using energy drinks as hydration; skipping rest to finish a segment; ignoring early heat symptoms.
