Some hazardous materials may have a specific what, while others have no what odor at all?

• A. smell; odor
• B. color; taste
• C. weight; scent
• D. sound; odor

Answer: (A)

Some hazardous materials may have a specific smell, while others have no odor at all. The idea here is that smell is the human sense used to detect odors, and odor is the noun that describes that smell. So some substances give off a distinct scent that you can notice, while others are odorless and cannot be detected by smell alone. This matters in incident response because relying on smell can help identification for some materials, but many hazards have no odor and require proper detection equipment, labels, and procedures. The other options don’t fit because they pair unrelated properties (color, taste, weight, sound) with odor, which doesn’t describe how some materials are detectable by smell versus being odorless.
