This Lakeland ChemMax 4 42400 Level B disposable encapsulated suit with rear entry and flat back is a totally encapsulating suit (TES) for protecting workers from hazardous materials in chemical manufacturing, hazardous waste cleanup, and pesticide application. It is made of polypropylene nonwoven fabric for lightweight strength, softness, and resistance to chemicals and moisture, and the fabric is coated on both sides with a multilayered barrier film for reduced penetration of air, moisture, and water vapor. This material resists for more than 480 minutes the penetration of all chemicals recommended in the ASTM International F1001 standard for evaluating protective clothing materials. The face mask is made of 20 mil thick polyvinyl chloride (PVC) for resistance to cracking and tearing, and the seams are sewn and sealed with a heat-activated tape to help block liquids and particulates. There is an air tube inlet and exhaust port for use with an external breathing airline. A double storm flap over the zipper, elastic closures at the wrists, and attached boot socks with boot flaps provide additional protection from hazardous materials.
Lakeland Industries manufactures protective clothing for foundries, ceramic manufacturers, chemical plants, and health care facilities. The company, founded in 1982, is headquartered in Ronkonkoma, NY.
