Abstract: A neck seal for use in a protective hood includes an inner section including a passage for donning. The inner section is fabricated from an elastomeric material to form a seal around a neck of a user. The neck seal also includes an outer section adhered to the inner section. The outer section is fabricated from a material heat sealable to a hood covering material. In one embodiment, the elastomeric material of the inner section is a latex material. The outer section can, for example, be fabricated from a thermoplastic material. In one embodiment the thermoplastic material is a polyurethane such as a polyester-based polyurethane.

Abstract: The present invention provides a respirator filter system suitable for filtering toxic agents, including organic vapors, acid gases, formaldehyde, ammonia, and methylamine as well as pesticides, CS and CN tear gases, dusts, mists, fumes and radionuclides from environmental air to be respired by a user of the filter system. In general, the filter system of the present invention includes a cartridge containing a layer of an unimpregnated activated carbon, a layer of an activated carbon impregnated with sulfate, molybdenum and at least one impregnate selected from the group consisting of copper and zinc, and a HEPA filter. Cartridges containing these adsorbents or adsorbents similar to them (in carbon tetrachloride activity and chemistry) have been discovered to be uniquely capable of filtering a broad range of toxic agents.

Abstract: A chemical resistant garment material, that is a laminate formed from layers of skived Teflon that have been adhered to a cloth substrate, for use in protective clothing to guard against exposure to toxic agents.
