What is the minimum approach distance after a derailment? (Reiterated)

• A. 1 ft
• B. 3 ft
• C. 6 ft
• D. 10 ft

Answer: (B)

After a derailment, create a safe buffer around the derailed equipment so you’re not exposed to unpredictable movement or hazards like moving wheels, damaged couplings, or ruptured lines. The minimum approach distance of three feet gives enough clearance to avoid contact with the car and its components while you quickly assess the scene and access needed areas. Approaching closer than three feet increases the risk of being struck by shifting parts or debris, whereas going much farther can slow down rescue and safety checks. So three feet is the practical, safe distance for initial approach after a derailment.
