Fumes are commonly hazardous and usually toxic. Which statement best reflects this?

• A. They are harmless in most cases
• B. They are hazardous and usually toxic
• C. They only affect the skin
• D. They are always visible and easy to detect

Answer: (B)

Fumes are airborne hazards that form when a solid or liquid is heated or a chemical reaction occurs, creating tiny particles or gases that you can breathe in. Because exposure happens mainly through inhalation, they’re often toxic and can affect the respiratory system, eyes, and other organs. That makes the statement that fumes are hazardous and usually toxic the best reflection of their nature. It’s not accurate to say they’re harmless in most cases, nor that they only affect the skin, and many fumes aren’t visible or easy to detect—colorless or odorless fumes can pose risk even when they seem imperceptible.
