Red Card Environmental Health & Safety 2 — Questions and Answers
Question 1: What is the primary purpose of the Work/Rest ratio guideline on wildland fire assignments?
- To schedule shift rotations among crew members
- To ensure firefighters receive adequate rest to prevent fatigue-related accidents (Correct answer)
- To determine overtime pay eligibility
- To regulate the number of hours equipment can operate
Correct answer: To ensure firefighters receive adequate rest to prevent fatigue-related accidents
The Work/Rest ratio (2:1 minimum) ensures firefighters get sufficient rest to remain alert and reduce fatigue-related injuries.

Question 3: When working near a helicopter landing zone (LZ), what is the minimum safe approach angle?
- From directly behind the tail rotor
- From the front at 10 o'clock or 2 o'clock positions with pilot's acknowledgment (Correct answer)
- From either side at a 90-degree angle
- Any direction as long as the pilot is notified

- Lookouts, Command, Escape routes, Staging
- Location, Command, Engagement, Safety
Correct answer: Lookouts, Communications, Escape routes, Safety zones
LCES (Lookouts, Communications, Escape routes, Safety zones) is the core tactical safety system used on every wildland fire.
Question 5: What is the greatest health risk associated with long-term smoke exposure on wildland fires?
- Skin irritation and sunburn
- Respiratory damage from fine particulate matter (PM2.5) (Correct answer)
- Eye strain from reduced visibility
- Increased risk of dehydration
Correct answer: Respiratory damage from fine particulate matter (PM2.5)
Fine particulate matter (PM2.5) in wildfire smoke penetrates deep into the lungs and poses the greatest long-term respiratory health risk.

- Slightly elevated heart rate and mild thirst
- Heavy sweating, weakness, cool/pale/moist skin, and nausea (Correct answer)
- Hot dry skin with no sweating and confusion
- Minor muscle cramps after heavy exertion
Correct answer: Heavy sweating, weakness, cool/pale/moist skin, and nausea
