With the same features as our 9910-D, the Maintenance Free Saran™ Hood offers effective protection against a broader range of chemicals. It is made of Tyvek® fabric that is laminated with saran to offer zero permeability to air and moisture, providing total protection against hazardous materials. The seams are heat tape sealed to form a liquid and gas-tight seal. It is ideal for acid handling, tank cleaning, agricultural pesticide handling, asbestos abatement, chemical handling and hazardous waste management. NIOSH approved.
