Survivair has obtained NIOSH approval for its Opti-Fit CBRN Gas Mask for use with the Opti-Fit Tactical canisters. This approval gives end-users the flexibility to use one gas mask, the Survivair CBRN Gas Mask with the Tactical canister, for riot situations and Survivair CBRN Gas Mask with CBRN canister for CBRN situations. The Survivair Opti-Fit CBRN Gas Mask with Tactical canister, available from Defense Technology, is lightweight, weighing less than 2.6 pounds, and helps to minimize fatigue when the mask is worn for an extended amount of time. It has an impact-resistant nylon frame and components with solid polycarbonate lens providing protection against flying debris that can penetrate synthetic rubber materials.
