Don't use water in irrigation systems or drainage ditches for washing produce or drinking as pesticides are sometimes applied to crops through irrigation. Empty pesticide containers, even after rinsing, have residues on them. They're unsafe for any purpose. If you find one, tell your supervisor. Never take a pesticide container home.
Pesticide residues can get on work clothes.
Wash work clothes separate from other clothes, preferably with hot water and laundry detergent, before you wear them again. Symptoms of pesticide contact with skin include staining, reddening, or blistering of the skin, an itching or burning sensation, or nail damage. Other poisoning symptoms include headaches, or irritation of the eyes, nose, and throat. Some of these symptoms are caused by other illnesses unrelated to pesticides, including heat stress. To reduce harmful effects of working in hot conditions, drink plenty of water supplied by your employer, and take needed breaks to cool down.
