MSA’s Response Escape Hood provides head and neck coverage and protection from chemical, biological, or riot-control agents. The hood features a high-efficiency particulate filter and 50 percent more carbon than similar canisters used by the U.S. armed forces to combat aerosols, gases, and vapors. Other features include a large bonded PVC lens, CO2 buildup-reducing nose cups, and cradle-type head straps for no-assistance donning.
