What term is listed on a Material Safety Data Sheet (MSDS) to describe a chemical that can produce life-threatening or seriously disabling health hazards?

Correct Answer: Option B — High toxicity

OSHA Hazard Communication Standards (29 CFR 1910.1200) require MSDS/SDS documentation to classify chemical hazards. High toxicity is the standard terminology used to identify substances that pose immediate life-threatening risks or severe, disabling health effects upon exposure, necessitating strict engineering controls and personal protective equipment to ensure crew safety.
