Pesticide Exposure and Personal Protective Equipment Gloves University of Minnesota Extension (Adapted from Penn State Pesticide Education Program)
0 of 180 What is the most common route of exposure for pesticide applicators? • Lungs • Mouth • Eyes • Skin
0 of 180 When are disposable latex medical gloves a good choice? • Granular formulations • Liquids • Low toxic products • Working on equipment • None of the above
0 of 180 Nitrile gloves provides high protection against all pesticides • Yes • No • Not sure
Exposure • How pesticides enter the body • You cannot control the toxicity of a product but, you can control your exposure to a product
4 Routes of Exposure • Dermal - any covered or uncovered skin • Eyes – direct splash or contact with hands • Inhalation – carried in with air • Oral – taken into mouth or on lips Skin Eyes Nose Mouth
Dermal Exposure • 97% of all pesticide exposures are dermal • The most common routeis through thehands and forearms
First Aid Measures • Rinse exposed area immediately with water • Remove contaminated clothing • Wash with plenty of soap and water • Check product label
Dermal Protection Look on the pesticide label PRECAUTIONARY STATEMENTS Explains the type of personal protective equipment (PPE) and work clothing needed 9
Dermal Protection • The label is very specific about the PPE required for mixing/loading, application, and early entry • Long-sleeve shirt, long pants, waterproof gloves, and shoes and socks are the minimum PPE found on most agricultural pesticide labels
“Breakthrough” Time • Some gloves may specify the length of time it takes for a chemical to move from the outside surface to the interior—the “breakthrough” time • Protection times vary: --Few minutes for single-use disposable --Several hours for repeated use gloves --Reusable gloves should have breakthrough of at least 240 minutes (4 hr.)
Dermal Protectionbased on the recommended 14 mls thick gloves HIGH: Highly chemical-resistant. Clean or replace PPE at end of each day's work period. Rinse off pesticides at rest breaks. MODERATE: Moderately chemical-resistant. Clean or replace PPE within an hour or two of contact. SLIGHT: Slightly chemical-resistant. Clean or replace PPE within ten minutes of contact. NONE: No chemical-resistance. Do not wear this type of material as PPE when contact is possible.
EPA chemical resistance category selection chart can be found on the EPA web site www.epa.gov/oppfead1/safety/ workers/ equip.htm
Disposable Latex Gloves • Good to prevent biological exposure – but not chemical exposure • Fast breakthrough time for almost all pesticides….. …..And then traps pesticide against your skin
Natural Rubber • Provide excellent hand protection from physical hazards such as cuts, punctures, abrasions • Limited chemical resistance • Do not hold up well in organic solvents, oils, greases, kerosene or gasoline
PVC • General work glove applications • Provide limited protection from chemical exposure and physical hazards • Economical and durable
Neoprene • Provide excellent hand protection from physical hazards such as cuts and abrasions • Excellent chemical resistance from exposure to organic and inorganic acids, organic solvents, oils, greases and petrochemicals
Nitrile • Provides tough protection from physical hazards such as cuts, puncture or abrasion • Designed for chemical resistance to petrochemicals, oils, greases, pesticides and other agricultural chemicals
Butyl • Provides excellent chemical resistance to gases and ketones • Ideal for handling hazardous materials • Butyl is affected by exposure to fuels and aromatic hydrocarbon solvents
Barrier Laminate • Resists breakthrough to nearly all pesticide formulations • These gloves are flat and are clumsy to wear. Wear fitted rubber gloves over barrier-laminate gloves for comfort, protection, and dexterity • They do not provide mechanical protection and should be used as a liner with nitrile or latex gloves.
Specific Glove Suggestions • EPA Worker Protection Standard says: -- Wear only unlined gloves OR -- Gloves with separate liners • Do NOT wear leather or cloth gloves -- They offer no chemical protection -- May absorb chemicals leading to pesticide poisoning • Gloves should be chemically resistant and at least 14 mls thick
How to Wear Your Gloves • When spraying downward: -- Put the sleeves over the gloves and fasten the cuffs • When spraying overhead: -- Put the shirt sleeves inside the gloves & turn up the cuff of the glove to catch any material that may run down your arm
After You Have Finished Your Work • To avoid secondary exposure & before removing the gloves: -- Thoroughly wash the gloves with soap & water -- Rinse with large amount of running water -- Then remove the gloves -- Thoroughly wash your hands and arms with soap & water
Glove Use & Maintenance • Inspect gloves for visual signs of wear before each use– i.e. cuts, holes, abrasions, bubbling, cracking.. • Discard if there are any signs of wear • Discard disposable gloves after use • Triple-rinse gloves before disposal, then cut off the fingers to prevent reuse • Keep an extra, clean pair of gloves in a zip-closed plastic bag in a location free of pesticides in case the pair you are wearing gets torn or contaminated
Glove Use & Maintenance-- continued…. • Store contaminated, reusable gloves in zip-closed plastic bag until final clean-up or disposal • Keep pesticide-contaminated gloves separate from other safety equipment • Never try to patch gloves with duct or electrical tape • Do not leave pesticide-contaminated gloves on surfaces such as truck floor board, seat, bed– pesticides can transfer to these surfaces • Never wear pesticide-contaminated gloves when feeding or watering livestock, harvesting fruits & vegetables or cleaning animal pens
Glove Summary • Always read the label to see what materials are resistant to the pesticide product • If the label does not specify a glove material select a barrier laminate, butyl or nitrileglove • Wear gloves that reach at least halfway to the elbow
Summary The best way to avoid a pesticide poisoning is to protect yourself by Reading the label and Wearing personal protective equipment
