The Environmental Protection Agency, the United States Department of Agriculture-Cooperative Extension Service, pesticide producers, or PPE dealers may offer guidance. Unless the pesticide label directs otherwise, do not use items that are made of or lined with absorbent materials such as cotton, leather, and canvas. These materials are not chemical-resistant, and they are difficult or impossible to clean after a pesticide gets on them. Even dry formulations can move quickly through woven materials and may remain in the fibers after several launderings. Product tags or catalog descriptions may specify thickness of material in mils.
Pesticides can leak through stitching holes and gaps in seams of protective garments.
For chemical resistance, choose PPE with sealed seams. Barrier-laminate materials are resistant to most pesticides and are a good choice for many situations. Dry pesticides include dusts, granules, pellets, and some baits. Common solvents are xylene, fuel oil, petroleum distillates, and alcohol. Then watch for signs that the material is not chemical-resistant.
