What visual indicators suggest a potential hot brake situation?
No Smoke, Heat Waves, Light Blue Smoke, Brakes Glowing, Fire, Tires overinflated or deflated.
How should ARFF ground crews approach a wheel in a hot brake situation?
Approach at a 45º angle with full PPE, SCBA, and shields down.
What is the safe minimum crew size when approaching a hot brake situation?
A minimum of 2 crew members must approach the situation.

What is the minimum handline size allowed to combat wheel fires?
Handline sizes must be 1½ inch or larger.
What is the safe standoff distance from a suspect hot tire or rim?
Stay at least 25 feet (7.6 meters) away from tire or rim until temperature returns to acceptable.
What are characteristics of extreme temperature conditions in hot brake scenarios?
Open flames and moderate to heavy dark colored smoke.
When should a mist from a fog pattern be used instead of fans?
When temperatures are increasing from minor to extreme but not yet at wheel fire conditions.
What is the safest method for extinguishing a wheel fire?
