Which statement is true about phenolic disinfectants?

• A. They Are Known Carcinogens
• B. They Are Non-Toxic to Skin
• C. They Are Ineffective Against Bacteria
• D. They Are Safe for Use in All Environments

Answer: (A)

Phenolic disinfectants carry notable safety concerns due to their toxicity and potential health risks with exposure. They are effective disinfectants, but they can irritate and damage skin and mucous membranes, and with prolonged or improper exposure there are safety concerns that lead to warnings about carcinogenic potential in some contexts. That combination—being powerful disinfectants while posing significant health hazards—is why the statement about carcinogenic risk is considered true in this item. They are not harmless to skin, they do work against bacteria when used correctly, and they are not safe for use in every environment or on every surface, which is why the other options don’t fit.
