Which agency classifies chlorine bleach solutions into three categories based on concentration and exposure time?

• A. TDLR
• B. EPA
• C. FDA
• D. CDC

Answer: (A)

The main concept is regulatory classification of disinfectant use to ensure safety and effectiveness in licensed settings. In Texas, the agency that writes the sanitation rules for licensed facilities (like salons, barber shops, and tattoo studios) defines how chlorine bleach solutions are categorized by how strong they are and how long they must be left on surfaces to achieve the desired level of disinfection. This three-category scheme helps workers know exactly what dilution to prepare and the correct exposure time for each cleaning scenario, preventing under- or over-dilution and ensuring compliance with state standards. Federal agencies such as the EPA, FDA, and CDC play important roles in labeling, guidance, and broader public health recommendations, but the specific three-category classification tied to licensing is provided by the state agency referenced here. Understanding this helps ensure proper disinfection practices in regulated facilities.
