Vapors that attack mucus membranes are?

• A. Neurotoxins
• B. Carcinogens
• C. Pyrogens
• D. Irritants

Answer: (D)

Vapors that attack mucus membranes are irritants. Irritants cause immediate irritation of moist surfaces such as the eyes, nose, throat, and airways, producing symptoms like burning sensations, tearing, sneezing, coughing, and a runny nose. This is about local irritation of mucous membranes rather than affecting nerve function, cancer risk, or body temperature. Neurotoxins disturb the nervous system and can cause dizziness, weakness, or paralysis; carcinogens increase cancer risk with longer exposure; pyrogens trigger fever. Classic irritants include substances like ammonia or chlorine gas, which directly irritate the mucus membranes.
