These lab coats and frocks have a snap closure and protect workers from non-hazardous particulates and non-hazardous liquid splash and spray. Dry particulates are larger in size than aerosols and include dust and dirt. Splash is non-pressurized or lightly pressurized when it contacts a garment, while spray is pressurized. Lab coats and frocks have a front closure and are worn by researchers and clinical staff to protect personal clothing from accidental spills and splashes and to prevent cross-contamination. Lab coats have pockets, while frocks do not.
