AUSTIN, TX — In mid-March, the U.S. Environmental Protection Agency (EPA) published a letter on the subject of “Use of Disinfectants and Sanitizers in Heating, Ventilation, Air Conditioning, and Refrigeration Systems.” Since then, experts from various business sectors have dissected and analyzed its contents.
The letter was the topic of discussion at one seminar at the recent Healthy Indoor Environments (HIE) 2002 Conference. In the letter, the EPA summarized its position:
“We recommend that you advise your members not to apply disinfectant, sanitizer, or other antimicrobial products to treat hvacr systems if such product does not include specific directions for hvacr use. The Agency believes that it is important that you ensure that members of your association are not applying products to hvacr systems which are not registered for that use.
