BACKGROUND: Personal protective equipment (PPE) are stockpiled across the nation to offset supply depletion during public health emergencies. Stockpiled PPE inventories vary across the United States by type, model, quantity, and the conditions in which they are stored. Over the past decade, federal, state, and local stockpile managers have had concerns for the viability of aging PPE. METHODS: To understand factors that may affect stockpiled PPE, we explored the breadth of stockpile storage conditions and respirator and surgical gown inventories through collaboration with the national PPE community, qualitative observations collected at 10 different US stockpiles, and by compiling stockpile PPE inventories and climate data from a convenience sample of US stockpiles. RESULTS: The aggregated inventory from 20 stockpiles is reported, accounting for approximately 53 million respirators. Most respirators (69% or 35.8 million) have been stored between 5 and 10 years. Upon visiting 10 stockpile facilities, we report on the storage conditions observed and summarize the storage environment data collected. CONCLUSIONS: This is the first study to identify common PPE types, inventories, and storage conditions across federal, state, and local government stockpile facilities as well as health care organization-managed caches. These findings will be leveraged to guide the development of sampling protocols for air-purifying respirators and surgical gowns in US stockpiles to understand the performance viability after long-term storage.

AbstractGiven the recent increase in dust‐induced lung disease among U.S. coal miners and the respiratory hazards encountered across the U.S. mining industry, it is important to enhance an understanding of lung disease trends and the organizational contexts that precede these events. In addition to exploring overall trends reported to the Mine Safety and Health Administration (MSHA), the current study uses MSHA's enforcement database to examine whether or not compliance with health regulations resulted in fewer mine‐level counts of these diseases over time. The findings suggest that interstitial lung diseases were more prevalent in coal mines compared to other mining commodities, in Appalachian coal mines compared to the rest of the United States, and in underground compared to surface coal mines. Mines that followed a relevant subset of MSHA's health regulations were less likely to report a lung disease over time. The findings are discussed from a lung disease prevention strategy perspective.
