According to USFA, the number of 30-minute SCBA bottles that trigger self-rehab can vary based on what factor?

• A. Mood
• B. Weather conditions
• C. Time of day
• D. Group size

Answer: (B)

The amount of time or air you can push before self-rehab is not fixed; it changes with environmental stress, especially the weather. Hot, humid conditions increase heat load and fluid loss, raising fatigue and heat strain, so rehab may be needed after using fewer 30-minute SCBA bottles. Cooler or milder weather reduces this strain, allowing longer air use before rehab is triggered. The USFA recognizes weather as a key factor in determining when self-rehab should be initiated, rather than sticking to a single bottle-count rule.
