Tyvek Coveralls are designed to protect individuals and clothing from dry particulates, aerosols and light non-hazardous liquid splash. OSHA regulations require employers to provide appropriate protective apparel, which does not permit blood or other potentially infectious materials to pass through under normal conditions of use. Our suits are available in two fabrics, Tyvek and Tychem QC. Tyvek is ideal for powdering applications and limited exposure to non-hazardous liquids. For exposure to body fluids and some chemicals, Tychem® QC is a better alternative. Comes with zipper front.
