Which statement describes the safety concern associated with phenolic disinfectants?

• A. They Are Known Carcinogens
• B. They Are Harmless to Humans
• C. They Evaporate Immediately
• D. They Are Non-Toxic to Skin

Answer: (A)

Phenolic disinfectants carry notable safety concerns because, while they’re effective at killing microbes, they can be harmful to people. They can irritate or burn the skin and mucous membranes, and exposure through skin contact or inhalation can be toxic. In many contexts they have been associated with carcinogenic risks in studies, which is why describing them as known carcinogens is the best summary of the safety concern. The other statements don’t fit: they’re not harmless to humans, they don’t evaporate immediately in a typical use scenario, and they aren’t non-toxic to the skin.
