This document is adapted from a fact sheet in the Safe Farm series produced by Iowa State University Extension. This fact sheet was updated February 1994. Few Iowans suffer acute poisoning from pesticide use today. This good safety record is possible because people are learning more about ways to minimize exposure to harmful chemicals.
Pesticides can enter the body through inhalation or accidental ingestion.
However, the most common and least understood means of poisoning is through skin absorption. Whether liquid spray or granular, all forms of pesticide can soil your clothes, putting them in close contact with your skin where they may be absorbed. Granules may not stick to fabrics or leave evidence of soiling, but cotton fabrics may hold their chemical residues. Usually underclothing, a long-sleeved shirt, long pants, a hat with a brim, socks, and chemically resistant gloves and boots are essential. Coveralls, a chemically resistant apron, face shield, and goggles or respirator may be indicated for persons who are mixing and loading chemicals.
