Why is smoking prohibited near many hazmat loading, unloading, and transport operations?
- A.Smoking is banned only inside the cab
- B.The rule is about litter
- C.Only gasoline stations enforce it
- D.Many hazmat vapors and materials ignite easily, so smoking and open flames are barred within a safety distance, commonly 25 feet, of certain loads such as flammables and explosives
Correct answer
D. Many hazmat vapors and materials ignite easily, so smoking and open flames are barred within a safety distance, commonly 25 feet, of certain loads such as flammables and explosives
Why
A cigarette is an ignition source in an area where vapor concentration can reach flammable range without being visible. The no-smoking buffer around tank fueling and flammable or explosive cargo operations is a simple, absolute control.
