68. An effective disinfectant bleach must have a registration number from which agency?

Answer: B

Explanation:

An effective disinfectant bleach must have a registration number from the EPA.

An effective disinfectant bleach is required to have a registration number from the Environmental Protection Agency (EPA) to ensure it meets safety and efficacy standards for public health.

A) CDC

The Centers for Disease Control and Prevention (CDC) focuses primarily on public health and disease control but does not regulate or register disinfectants. Therefore, a disinfectant bleach would not require a registration number from the CDC.

B) EPA

The Environmental Protection Agency (EPA) is responsible for the regulation of disinfectants, including bleach, under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). A registration number from the EPA confirms that the product has been evaluated for its safety and effectiveness as a disinfectant.

C) FDA

The Food and Drug Administration (FDA) regulates food and drug products, but it does not oversee disinfectants or sanitizers. Therefore, a disinfectant bleach would not be required to have a registration number from the FDA.

D) SDS

Safety Data Sheets (SDS) provide information about the properties of a chemical substance, including hazards and safety precautions, but they are not an agency. Thus, a disinfectant bleach does not obtain a registration number from an SDS.

Conclusion

The requirement for a registration number from the EPA for disinfectant bleach is crucial for ensuring that these products are safe for use and effective in killing pathogens. The other options do not fulfill this regulatory role, highlighting the importance of the EPA in maintaining public health standards related to disinfectants.
