Question

The MSDS for benzene indicates that it is a clear liquid that has a substantial vapor pressure. It has a health rating of 2, a fire rating of 3, and a reactivity rating of 0. It is a cancer-causing agent.

Based on this information, which statement about benzene is accurate?
Benzene readily reacts with moist air.
Benzene explodes if the container is shaken.
Benzene must be kept away from flames.
Benzene must be stored under high pressure.

Answer 1

"Benzene must be kept away from flames."

Reason: a fire rating of 3 indicates a serious flammability hazard and its substantial vapor pressure means it can form ignitable vapors. The reactivity rating of 0 shows it does not readily react with moist air, and it does not need to be stored under high pressure.
