The National Institute for Occupational Safety and Health (NIOSH) has published a blog post offering best practices for employers to maintain effective stockpiles of essential personal protective equipment, such as respirators, for emergency situations. The guidance covers topics like shelf-life extension, storage recommendations, and inventory rotation strategies.

Why it matters

Having a reliable supply of respirators and other critical PPE is crucial for protecting workers during public health emergencies and other crises. NIOSH's recommendations can help employers avoid costly replacements and ensure their stockpiles remain usable over the long term.

The details

NIOSH's guidance is based on research that evaluated nearly 4,000 filtering facepiece respirators from 10 stockpile facilities across the country. The agency advises employers to closely follow manufacturers' instructions on shelf life and storage conditions, as disposable N95 respirators typically have a 5-year shelf life while reusable respirators may have different shelf lives for their various components. NIOSH also recommends maintaining detailed documentation on respirator inventory, including manufacturing dates, lot numbers, and storage conditions.
