MCU gas masks are made of silicone, and although silicone is desirable due to its hypoallergenic properties, which is an issue for users with sensitive skin, it deteriorates when exposed to blister agents for extended periods. In order to pass CBRN requirements and tests, the Millennium needed to be made of a material that would not lose its integrity when exposed to hydrogen nitride and other corrosive blister agents. The chief advantage the Millennium has compared to the MCU-Series, is in its use of Hycar nitrile rubber as the primary mask material instead of Butyl or Silicone, which was introduced on the Advantage 1000 in early 1990s. The resulting gas mask system, which used a very similar yet improved design and improved materials, would eventually be called the MSA Millennium. To simplify research and development, the mask's design was derived from the industrial MSA Advantage 1000 gas mask, which in turn is a civilian version of MCU-2/P that they were selling to the US Air Force and Navy. MSA, which was one of the industry leaders involved in the creation of the new standards, developed one of the first masks that would meet and exceed these standards. Chief among the standards that had to be met were prolonged resistance against NBC agents, mask penetration and permeation, field of view, equipment interoperability and ability of equipment to operate reliably (at least 15 minutes) in environments with very high concentrations of chemical agents (including hydrogen sulfide and nitride, which damages silicone-based materials and masks). Army Edgewood Chemical Biological Center. The new standards were released in conjunction with tests and results derived by the U.S. The National Institute of Occupational Safety and Health (NIOSH), which was new back then, first released the CBRN standard on March 7, 2003. This would eventually be known as the "CBRN compliant" classification. Because of this, and the ongoing threat of terrorist-deployed NBC agents, the US Government, Mine Safety Appliance (MSA) and related industries accelerated ongoing research on developing a new set of very stringent standards that would define protective clothing and respiratory systems. Has dual-canister mount to allow weapon firing from either shoulder.Īdvantage® 1000 CBA-RCA Gas Mask The Advantage 1000 CBA-RCA Gas Masks from MSA are specifically designed for use by law enforcement and emergency response personnel.The facepiece features a single low-profile canister.The gas mask is NIOSH approved (No.TC-14G-0235) for protection against chloroacetphenone (CN), chlorobenzylidene (CS), P100 particulate efficiency level and particulates.The gas mask does not have NIOSH approval for oleoresin capsicum, the “active” ingredient of OC Tear Gas.The canister provides up to eight hours service time against CN, CS, and OC agents.After the terrorist attacks of 9/11, the respiratory health issues encountered by the first responders (from all the dust and smoke) who didn't have adequate protection and the anthrax mails which followed shortly after, it was clear that there were inadequacies with the current equipment available to first responders. Is effective against biological agents and chemical warfare agents.Is effective against, but does not have approval for OC tear gas.Is NIOSH approved for protection against CN and CS tear gas.Has flexible, one piece polyurethane lens with wide field of vision, bonded to a durable super-soft Hycar rubber facepiece.Advantage® 1000 CBA-RCA (Chemical/Biological Agent-Riot Control Agent) Gas Mask
