Moderately toxic chemicals can be poisonous to you when they are used day after day. Pesticides can contaminate clothing and may soak through to your skin. Do not work in drift, spray, or runoff unless you are properly protected. If pesticides spill on your gloves, be careful not to wipe your hands on your clothing. Work in pairs when you are dealing someone else is doing repair work on equipment that has not been cleaned, warn them of possible hazards. Do not allow children, pets, or unauthorized people near the pesticide equipment. If you are working some distance from your equipment or at the end of a long spray hose, have someone keep watch near the sprayer so that no one gets injured by the machinery.
