The National Institute of Occupational Safety and Health (NIOSH) has been gathering information about storage conditions and inventory for personal protective equipment (PPE) in federal, state, municipal, county, and hospital system stockpiles. Maintaining the stockpiles for public health emergencies, such as infectious disease outbreaks, is a “significant cost and time investment,” NIOSH says. That investment includes restocking and leasing or purchasing environmentally controlled storage space.
NIOSH asked for comments on how facilities monitor respirator and gown deterioration, how they rotate PPE, and the degree to which environmental controls are implemented and maintained. Even when resources exist to store PPE per the manufacturer’s recommendations, NIOHS says, “the influence of long-term storage time alone or PPE performance has been questioned.”
The period for comment is closed. Survey responses will be used to inform a research study in which N95 respirators and high-protection–level surgical gowns are sampled from stockpiles nationwide and tested against established performance standards. The study will assess the potential to extend manufacturer-recommended shelf life and the effect of “common, albeit sometimes non-ideal, stockpile conditions” on the protections provided by respirators and surgical gowns.
The information collected will be added to the PPE database, available at https://wwwn.cdc.gov/ppeinfo.
