Which hazard class covers explosives?
- A.Class 9
- B.Class 1, divided into divisions that reflect how readily the material can mass-explode or project fragments
- C.Class 2
- D.Class 7
Correct answer
B. Class 1, divided into divisions that reflect how readily the material can mass-explode or project fragments
Why
Explosives are Class 1, and the division number matters because a mass-explosion hazard and a minor projection hazard demand different handling and distances. Drivers hauling them need the proper endorsement and must follow route and parking restrictions.
