1. What major challenges or restraints affect escape respirator suppliers?
Certification delays at NIOSH, FDA or EU notified bodies, high compliance testing costs, and short product shelf life are the primary constraints. Escape respirators must be approved as respirators even though they are used only for emergency evacuation, which can add 8 to 14 months to product launch timelines. Activated carbon filter cartridges typically expire within five to six years, so inventory is harder to manage than in ordinary PPE.
