Abstract
The present invention provides a readily disposable hazardous chemical and medical waste protection wear suitable for human use through utilization of a breathable, stand alone or combination laminant utilizing polyvinyl alcohol sheet material which is water soluble at various temperatures providing disposal of the stand alone or outer coating of a laminate material if utilized with reusable protection wear. The polyvinyl alcohol stand alone provides the wearer with comfort through having a MVTR rate of at least 450 grams/meter squared per 24 hours. In addition, a combination of polyvinyl alcohol and polyvinylidene chloride provides a readily disposable splash suit which is most suitable for a variety of chemicals while yet being readily disposable ie. the PVA being readily soluble in warm water and the PVDC being dispensable in water and being biodegradable.
