Cleanroom hoods prevent the spread of contaminants, reduce the buildup of ESD (electrostatic discharge) and protect workers from light liquid splash and particulates. They are sterile hoods that cover the neck, shoulders and head and leave only a small portion of the face exposed. Cleanroom hoods come with serged or bound seams to reduce ESD. They are made of polyethylene, polypropylene/polyethylene laminate and SMS fabric.
