Protecting people from exposure to respiratory hazards in both occupational and non-occupational settings is a public health imperative. Use of effective respiratory protection is one of the primary ways to protect against such hazards. Respirator Fit Capability (RFC) testing is the process used to assess whether a specific make and model of respirator provides acceptable fitting characteristics for a broad spectrum of potential wearers. RHP Risk Management conducts respirator and barrier face covering testing for PPE manufacturers seeking quantitative verification under ASTM F3407-20 and ASTM F3502-21 standards, both of which were created to ensure protection from exposure to respiratory hazards.
