The iEvac ® Smoke/Fire Hood is accredited by the Security Equipment Institute (SEI) as being in complete conformance with ANSI/ISEA 110-2009, American National Requirement for Air-Purifying Respiratory Protective Smoke Escape Gadgets. This certification is earned after substantial independent screening to prove compliance with every requirement in the Standard. This screening was performed by Intertek and Assay Technology. Unlike other smoke hoods which have only a material neck dam, the iEvac has a silicone neck dam for the highest level of protection. The iEvac, made from a clear product, uses a better field of view over other smoke masks & smoke hoods which have only a small window. And, compared with smoke hoods that have a single filter in front, our dual filters do not obstruct your view. These double filters likewise allow for easier breathing, crucial when you are breathing hard and fast in a demanding circumstance. 3 high-visibility reflective strips help first responders by making the wearer simple to locate in darkness and smoke.
