Are you allowed to smoke or use open flames near hazmat in transit?

• A. No; smoking and open flames must be prohibited near hazmat loads.
• B. Yes, if the material is non-flammable.
• C. Only if the truck is parked and not moving.
• D. It is allowed as long as you are a certified hazmat transporter.

Answer: (A)

Smoking or open flames near hazmat must be prohibited. Hazmat loads can ignite from sparks, flames, or heat, and many materials carry a high risk of ignition whether in transit or during loading and unloading. Even if a material is non-flammable, vapors, reactions, or static electricity can still create ignition hazards, so the risk remains in the vehicle, at stops, and around the cargo. Regulatory and safety rules require keeping ignition sources away from hazmat regardless of movement or status; simply being a certified hazmat transporter does not override this rule.
