Ben Hirst Hazardous Materials Awareness and Operations Practice Exam

Body irritants produce local irritation to the skin, eyes, and respiratory passages. The most reliable signs are unexplained irritation of the skin, eyes, or airway—redness, burning, itching, tearing, coughing, or shortness of breath soon after exposure. That’s why this option fits best: it directly describes the common, immediate symptoms people notice from irritants.

The other items aren’t typical signs of body irritants. A white vapor cloud relates to how the material is released or disperses in the environment, not a person’s symptoms. A metallic taste can occur with some exposures but isn’t the defining sign of irritants and can happen with various chemicals. Unequal pupils point to neurological or systemic effects, which isn’t the usual pattern for irritants that primarily irritate tissues.
