Dear Ms. Harrigan-Farrelly:

On behalf of the Association for Professionals in Infection Prevention (APIC), the Society for Healthcare Epidemiology of America (SHEA) and the Association for the Healthcare Environment (AHE) formerly ASHES, we welcome the opportunity to comment on the topic of fogging applications for disinfectants. The issues are very pertinent to our organizations and we are responding collectively to reinforce our close agreement on mutual concerns, especially worker safety.....When used properly, HP also likely offers a greater margin of safety compared to other chemicals that can also be applied by vapor such as chlorine dioxide or ozone.(Davies A, 2011, in press JHI)

7. Are there any active ingredients that may be problematic for your facility as foggers?

Ingredients that affect OSHA exposure limits that may affect workers, especially agents such as formaldehyde or phenol-based agents, would be a concern. The latter were chemicals that stimulated investigation and ultimately specific recommendations against their use by CDC. Other chemicals such as chlorine dioxide and ozone also have many documented safety issues that would preclude their use in healthcare facilities.(Davies,JHI2011)
