What is a poison inhalation hazard and why does it get special treatment on papers and placards?
- A.Any material with an unpleasant smell
- B.A material that is dangerous if inhaled, flagged with the words 'Inhalation Hazard' and special placarding, because even a small release can create a lethal zone downwind
- C.A material that is only dangerous if swallowed
- D.A hazard limited to food products
Correct answer
B. A material that is dangerous if inhaled, flagged with the words 'Inhalation Hazard' and special placarding, because even a small release can create a lethal zone downwind
Why
Poison inhalation hazard materials can injure people far from the vehicle through the air, so the papers highlight them and placarding rules are stricter. Drivers must treat route, parking, and incident isolation for these loads with extra seriousness.
