A carboy may be used for transporting materials containing which hazard class?

• A. Corrosives
• B. Flammable liquids
• C. Radioactive materials
• D. Toxic gases

Answer: (A)

Carboys are large, rigid bottles (often glass or durable plastic) used to transport liquids in relatively small quantities. They’re chosen for liquids that can be stored safely in a container that is resistant to corrosion, with a tight seal to prevent leaks. Corrosive chemicals—like acids and bases—fit well with this type of packaging because the container material can resist chemical attack and still be sealed securely.

Other hazard classes require different packaging. Flammable liquids generally need packaging designed to control vapors and reduce ignition risk, radioactive materials require shielding and specialized containment, and toxic gases need gas-tight cylinders or other pressurized containment. So a carboy is the best match for corrosives.
