What type of health hazard is classified as an irritant?

An irritant is classified as a substance that causes inflammation or irritation to tissues upon contact. In this context, dermatoxins specifically refer to chemical agents that irritate the skin or mucous membranes. They can lead to dermatological issues such as redness, itching, and inflammation, representing the key characteristic of irritants.

Carcinogens are substances that can lead to cancer development but do not primarily act as irritants. Neurotoxins affect the nervous system, potentially causing various neurological symptoms, but again do not classify under the irritant category. Corrosives, while harmful, specifically cause destruction of tissue and are often more severe, leading to chemical burns rather than just irritation. Thus, among the options provided, dermatoxin best fits the definition of an irritant.
