Red Card Environmental Health & Safety 3 — Questions and Answers
Question 1: What action should a firefighter take if they become trapped and cannot reach a safety zone before fire overtakes them?
- Run uphill to gain elevation advantage
- Deploy their fire shelter in a cleared, low-fuel area (Correct answer)
- Climb the nearest large tree to escape radiant heat
- Submerge in any available water source
Correct answer: Deploy their fire shelter in a cleared, low-fuel area
Deploying a fire shelter in a cleared area with low fuel is the last-resort survival action when escape to a safety zone is impossible.
Question 2: What is the recommended minimum daily water intake for a firefighter engaged in heavy physical activity in hot conditions?
- 1 quart per hour
- 1 liter per hour up to 1.5 quarts per hour maximum (Correct answer)
- Half a liter every two hours
- Drink only when thirsty to avoid hyponatremia
Correct answer: 1 liter per hour up to 1.5 quarts per hour maximum
NWCG guidelines recommend drinking 1 quart (approximately 1 liter) per hour during heavy work in heat, not exceeding 1.5 quarts per hour.
Question 3: Which of the Ten Standard Firefighting Orders directly addresses the importance of knowing where you are at all times?
- Order 1: Fight fire aggressively
- Order 3: Identify escape routes and safety zones (Correct answer)
- Order 5: Post a lookout when there is possible danger
- Order 8: Give clear instructions and ensure they are understood
Correct answer: Order 3: Identify escape routes and safety zones
Order 3 requires firefighters to identify escape routes and safety zones, which depends on knowing your position relative to the fire at all times.
Question 4: What hazard do 'widow makers' present on the fireline?
- Electrical hazards from downed power lines
- Falling dead trees or branches that can strike firefighters without warning (Correct answer)
- Hidden sinkholes caused by underground burning roots
- Toxic gas pockets released from burning vegetation
Correct answer: Falling dead trees or branches that can strike firefighters without warning
Widow makers are dead trees or branches weakened by fire or rot that can fall without warning, posing a serious strike hazard.
Question 5: Which of the following best describes the concept of a 'safety zone' in wildland firefighting?
- Any area designated by the Incident Commander on a map
- An area large enough to provide refuge from radiant and convective heat without a fire shelter (Correct answer)
- A cleared buffer strip adjacent to the fireline
- Any natural feature such as a river or rock outcrop
Correct answer: An area large enough to provide refuge from radiant and convective heat without a fire shelter
A true safety zone must be large enough for all threatened personnel to survive the fire's passage through radiant and convective heat without deploying fire shelters.
Question 6: What is the primary environmental concern when using retardant near waterways during a wildland fire suppression operation?
- The retardant may change the color of the water
- Retardant contains ammonia-based compounds toxic to aquatic life (Correct answer)
- Retardant increases water temperature significantly
- The chemical foam reduces oxygen levels in the atmosphere
Correct answer: Retardant contains ammonia-based compounds toxic to aquatic life
Long-term fire retardants contain ammonia-based fertilizers that are toxic to fish and other aquatic organisms and must not be dropped within 300 feet of waterways.
Question 7: A firefighter notices their urine is dark amber or brown in color during an extended shift. This indicates:
- Normal coloring from eating field rations
- Severe dehydration requiring immediate rehydration (Correct answer)
- A side effect of smoke inhalation
- Adequate electrolyte levels
Correct answer: Severe dehydration requiring immediate rehydration
Dark amber or brown urine is a clear sign of severe dehydration; clear to pale yellow urine indicates proper hydration.
