Field studies show that wearing gloves reduces pesticide exposure on your hands. If you think gloves are uncomfortable, clumsy, difficult to get on or off, and hard to manage, for safety’s sake, think again. This publication may help you find gloves you like better.

Choose the right glove
Precautionary statements on pesticide labels state whether waterproof or chemical resistant gloves are required. After that, the choice is yours. Cotton, canvas, and leather gloves are not acceptable for pesticide work. However, rose growers can wear leather gloves on top of chemical resistant gloves when thorns are a hazard.
Pesticide formulation. Suitable chemical resistant glove materials vary with the form of the pesticide. No glove resists all chemicals equally well.
Glove thickness. Thicker gloves usually offer more protection because they resist tearing and puncture, but thickness can also reduce your grasping ability and manual dexterity. For pesticide work, suitable thickness varies with the material, the task, and how long it takes to do it.
Glove thickness is measured in gauge (inches) or mils (1 mil = 0.001 inch). The higher the number, the thicker the glove. For neoprene, the typical thickness is 22 mil, but for nitrile, it may range from 11-22 mil. Some of the most chemical resistant gloves are very thin and meant to be worn a short time. Barrier laminates and singleuse nitrile thicknesses are 4 to 8 mil but are intended to be worn 8 hours or less. If thickness and dexterity or grasping ability is a concern, put the glove on and test it by picking up a pencil or coin.
Glove fit and length. Your glove size should be the same as your hand measures in inches around your palm. If your hand is 9 inches around the palm, try a Medium and a Large size to see which works best for you.
5-7 Extra small
10-12 Extra large
Glove length needs to change with your task. For most tasks, a glove must cover your wrist and probably should be about 12 inches long. You can get gloves that reach over your elbows if you need to reach into chemicals.
Glove construction affects fit. Gloves are made in either a handprint design that can be worn on either hand or by dipping a hand mold into the molten polymer. The latter provides for shaped gloves with curved fingers. Different manufacturers use different hand molds, so finger length, size, palm dimensions, etc. vary a lot. Try on sample gloves to find your best fit.
Wearing gloves. Chemical resistant gloves do not help you if they are not available to wear when you need them. Keep several clean extra pairs in zip-close bags in the cab of your tractor or truck. After use, put them back in a bag, so they don’t contaminate surfaces they contact.
Use common sense about wearing gloves over or under sleeve cuffs. Wear gloves over your sleeve cuffs unless you are working in a drenching spray from above. Then put gloves under your sleeves so the chemical doesn’t run down your sleeve and arm into the glove.
Taking gloves off. Peel one glove off by grasping the cuff, then hold it wrong-side out in the ungloved hand as you peel off the other glove. Both will be wrong side out, with the contamination inside. Never pull gloves off with your teeth.
Glove cleanup. If possible, rinse gloves under running water before you take them off. Washing gloves can reduce contamination on the outside, but some may be retained in the thickness of the gloves. The health hazard represented by this is unknown. Flush gloves in running water, then wash the outside with soapy hot water if you intend to reuse them. Never put gloves in the washing machine because they will get contaminated inside and spread pesticide to other items via the wash water.
Glove replacement. All gloves must be replaced frequently. Pesticides can permeate glove materials without showing evidence of damage to the glove. You may not see any pesticide on them, but tests with fluorescent dyes have shown that gloves are easily contaminated during pesticide handling. Disposable gloves may only be worn a few minutes, then thrown away. Watch for the warning signs that show when reusable gloves need replacement:
Glove disposal. Cut the fingers off gloves if you put them in the trash so no one else will be tempted to use them. Contaminated gloves may be handled in the same way as pesticide containers or bags.
