- Background Information: NIOSH sought information about personal protective equipment (PPE) environmental storage conditions and inventory for federal, state, municipal, county, and hospital system stockpiles. Maintaining PPE stockpiles for public health emergencies is a significant cost and time investment for these various entities, which may include purchasing new products, maintaining inventory records, and lease or purchase of environmentally controlled storage space away from contaminated areas, dust, sun light, extreme temperatures, excessive moisture, and damaging chemicals. The information provided by respondents to this Notice was used to inform a research study design where N95 respirators and high-protection level surgical gowns are sampled from stockpiles and tested against established performance standards. The research study was designed to obtain scientific data to assess 1) the potential to extend manufacturer-recommended shelf life and 2) the effect of common, albeit sometimes non-ideal, stockpile conditions on the protections provided by respirators and surgical gowns. NIOSH seeks to sample N95 respirators and high-protection level surgical gowns from a variety of stockpiles representing contemporary storage conditions from across the nation. To that end, the information sought in this Notice was aimed at ensuring that study findings are broadly applicable to U.S. stockpiles.
