Which sense should not be used intentionally to identify hazardous materials?

• A. Taste, touch, or smell
• B. Vision
• C. Hearing
• D. None of the above

Answer: (A)

Never use taste, touch, or smell to identify hazardous materials. Tasting a chemical can poison you or cause burns; skin contact can lead to absorption and injury; and odors can be absent, faint, or misleading, so you can’t rely on smell to tell you what a substance is or how dangerous it is. Instead, use labels and placards, consult the Safety Data Sheet, and depend on proper detection equipment and established procedures to identify hazards and guide your response. Visual cues like warnings and alarms help, but they should be verified with proper information and safeguards rather than your senses.
