Required Components 1) Faceniece The facepiece shall have a large diameter inlet serving as the female half of a quarter (1/4) turn coupling which mates with the positive pressure breathing regulator. The facepiece shall be approved for use with multiple respiratory applications to enable the same user to switch from one application to another without the use of tools and without doffing the facepiece. The full facepiece assembly shall fit persons of varying facial shapes and sizes with minimal visual interference. The full facepiece assembly shall be available in three sizes marked "S" for Small, "M" for Medium, and "L" for Large. The facepiece sizes shall be easily identifiable through a color- coding scheme. The facepiece assembly, including head harness, shall be latex free. The facepiece series shall have a faceseal that is secured to the lens by a U- shaped channel frame that is retained to the lens using two fasteners. The faceseal shall be a reverse reflex design for enhanced fit and comfort. The facepiece shall contain inhalation valves that are readily visible to enable quick visual inspection. The lens shall be a single, replaceable, modified cone configuration constructed of a non - shatter type polycarbonate material. In accordance with NIOSH 42 CFR part 84, the facepiece meets penetration and impact requirements, including compliance with ANSI Z87.1 — 2010. The lens shall have a coating to resist abrasion and chemical attack and meet the requirements of NFPA -1981, for lens abrasion. The lens shall have an internal anti -fog coating to reduce fogging of the lens. Mutli- directional voicemitters shall be mounted on both sides of the facepiece and ducted directly to an integral silicone nosecup to enhance voice transmission. The facepiece assembly shall be able to incorporate multiple electronic communications options (amplification, radio interface, wireless, etc.) without affecting NIOSH approvals or NFPA /CBRN approvals where applicable. The facepiece shall enable the transmission of communications bracket on either the right or left side. The head harness shall be a five -point suspension made in the fashion of a net hood to minimize interference between securing of the facepiece and the wearing of head protection, and be constructed of a para - aramid material for fire, first responder and CBRN applications. CONFIRM EXCEPTION 2) Mask - Mounted Regulator The facepiece- mounted positive pressure- breathing regulator shall supply and maintain air to the facepiece to satisfy the needs of the user at a pressure greater than atmospheric by no more than 1.5 inches of water pressure static. The breathing regulator shall maintain positive pressure during flows of up to 500 standard liters per minute. The regulator shall also meet or exceed a dynamic flow requirement of remaining positive while supplying a minute volume of 160 liters. The breathing regulator shall have attached a low pressure hose which shall be threaded through the left shoulder strap to couple to the pressure reducing regulator mounted on the backframe. 2
