Which wind chill threshold value in Fahrenheit is used to trigger rehab decisions?

• A. 10ºF (-12ºC)
• B. 15ºF (-9ºC)
• C. 20ºF (-7ºC)
• D. 25ºF (-4ºC)

Answer: (A)

Wind chill shows how cold it truly feels when wind is factored in, which accelerates heat loss from the body. In firefighter rehab decisions, this perceived cold is used to decide when to bring a crew in for rest, warming, hydration, and medical recheck. When the wind chill is at or below 10°F (about -12°C), the risk of rapid heat loss and cold-related injury increases enough that initiating rehab becomes the prudent move to protect safety and performance. Values higher than that, while still cold, do not automatically trigger rehab in many protocols, so 10°F is the standard trigger point.
