(1 RC) - Chemical, biological, radiological, and nuclear (CBRN) hazards are constantly evolving in type, intent of use, and ways of dissemination. Emergency responders would most likely use air-purifying respirators (APRs) with CBRN cannisters against all hazards in an intentional or unintentional event. Thus, new and emerging hazards must be identified to ensure APRs with CBRN canisters continue to provide protection to those responders… (NIOSH, May 2025)
