Another great question and answer:
Q. Which disinfectant should I use when disinfecting environmental surfaces?
A. Your facility will specify the EPA approved hospital grade disinfectant to use. A good rule is to only use disinfectants registered with the U.S. Environmental Protection Agency (EPA). See http://www.epa.gov/oppad001/active-hospital-disinf.pdf. Remember to always follow the instructions on the product label. Pay close attention to the purposes indicated on the product label, the proper dilution rates (if provided), the contact time required, the product shelf-life, and all safety instructions for handling and use. Do not mix cleaners and disinfectants unless the product label says that it is safe to do so.
