Why should you not smell, taste, or touch HazMat substances?

• A. Because HazMat materials are always inert
• B. Because many HazMat materials can cause injury or toxicity; odors can be misleading and direct contact can cause harm
• C. Because smelling reveals identity safely
• D. Because tasting is a common method of identification

Answer: (B)

Odors and taste are not reliable indicators of HazMat danger, so you should avoid smelling, tasting, or touching unknown substances. Many hazmat materials can injure or be toxic even at very small exposures, and relying on a sniff or a taste test can expose you to inhalation or ingestion risks, or skin absorption if you touch the material. Odors can be misleading: some dangerous substances have no odor, others may have an odor only at certain concentrations, and your sense of smell can fade or adapt, making it easy to miss danger. The safe approach is to treat any unknown material as hazardous and use proper detection equipment, labels, and PPE rather than your senses to identify it.
