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. This hood is ideal for acid handling, tank cleaning, agricultural pesticide handling, asbestos abatement, chemical handling and hazardous waste management.Do you order this product often and/or in large quantities?
