1 What Do We Know About Personal Protective Equipment and Pesticide Labels? Carol Black Pesticide Education Specialist

2 Acknowledgments Dr. Anugrah Shaw, University of Maryland Eastern Shore Dr. Jeff Evans, US EPA OPP Health Effects Division

3 The Pesticide Label Risk Assessment Toxicity Formulation Use pattern Dermal exposure Inhalation exposure Closed-mixing systems pesticidepics.org VERY RARELY would this much protection be warranted, and extremely doubtful being a solid formulation

4 The Pesticide Label Who is Exposed? Mixer-loaders Applicators Equipment maintenance PPE is noted on the label per task Lorsban 4E (2012)

5 Dr. Anugrah Shaw – Univ. of Maryland Eastern Shore No aggregate data was available to determine the scope of the PPE challenges Label review manual is fairly prescriptive for PPE language What is really being required

6 PPE label-language database was developed by Dr. Anugrah Shaw to obtain information that would assist in determining the scope of the issue with the current PPE requirements on the label.

7 Personal Protective Equipment Clothing Eye Protection Gloves Respiratory Protection

8 EPA Matrix for PPE: Dermal & Inhalation Toxicity Other factors, in addition to default acute toxicity values, are used.

9 Review of Glove Materials Barrier Laminate Butyl Rubber Polyethylene Neoprene Viton Nitrile PVC polyvinylchloride

10 Review of Glove Thicknesses Nitrile 15 mil Nitrile 8 mil Nitrile 5 mil Latex® 20 mil Disposable vinyl

11 Gloves – The Beginning A.D. Little and EPA/ORD 100 tests 20 pesticide formulations 13 glove materials Permeation Resistance of Glove Materials to Agricultural Pesticides Guidance Manual for Selecting Protective Clothing for Agricultural Pesticides Operations A.D. Little, peer-reviewed by EPA

12 Gloves – The Basis Solvents generally permeate first* Labels are based on solvent types Labels should list TYPE of glove, not code Label - means gloves can be worn all day Carrier SolventSelection Category Type No solvent or aqueous solvent A -- waterproof Ketones B Alcohols C Acetates D Aliphatic Petroleum Distillates E Aromatic petroleum Distillates < 40% F Aromatic petroleum Distillates > 40% G Halogenated Hydrocarbons H

13 EPA Glove Type Selection Best matches the handling task duration Based on solvents used in pesticides, not the pesticides themselves Two formulations of the same active ingredient may require different glove types pesticidepics.org

14 Only Gloves Rated High Are Selected for Labels Solvent Category Barrier Laminate Butyl Rubber 14 mils Nitrile Rubber 14 mils Neoprene 14 mils Natural Rubber 14 mils* Poly- ethylene Polyvinyl Chloride (PVC) 14 mils Viton 14 mils A (dry and water- based) High B Slight NoneSlight C High Moderate High D Moderate None Slight E High Slight High SlightNoneModerate High F ModerateSlightNoneSlight High G Slight None High H Slight None High Nitrile $2.95 Viton/Buty l $72.25 per glove Neoprene $7.50 Barrier Laminate $5.70 Butyl Rubber $24.90 Polyethylene $0.99 Approximate price per pair (A.Shaw) EPA Chemical Resistant GLOVE Chart -- as noted for all-day tasks

16 1.How many different glove materials do you wear during a year? Same – 2 types – 3 types -- More than 3 2.Do you wear the same glove material when you mix/load and apply? Yes – No -- Dont wear gloves 3.Do you wear the same glove thickness when you mix/load and apply? Yes – No -- Dont wear gloves

17 1.Do you wear the same glove for different pesticides? Only handle 1 product – Use same glove for different products – Use different glove for different products 2.Do you wear the same glove for different handling tasks? Only do 1 task– Use same glove for different tasks– Use different glove for different tasks

18 Protective Clothing All PPE images taken from gemplers.com and amazon.com

19 Clothing label language is based on garment type and layers of garments not any scientific garment/fabric standard. Fabric performance varies considerably Performance depends on the material and the finish applied to the fabric. Data show that a pant/shirt can have much better protection than some coveralls. New ASTM and ISO performance-based standards for fabrics/finishes are in place Scientists are conducting wear studies prior to implementation in the US Used in Europe and Brazil Protective Clothing

20 1.What layers are typically worn when you apply pesticides Single layer – pants/shirt Coverall (cotton/polyester) over pant/shirt Tyvek-like water resistant over pant/shirt Rain-suit-like impermeable over pant/shirt

27 Review of Glove Materials Barrier Laminate Butyl Rubber Polyethylene Neoprene Viton Nitrile PVC polyvinylchloride

28 Questions about Gloves 1.What glove material is worn most often? 2.What is the primary reason for glove selection? 3.If wearing more than one glove type, what is the second most common selection?

29 Polyethylene460 PVC 395 Butyl Rubber285 Neoprene 270 Nitrile 192 Barrier Laminate 0 Viton 32 When More than Waterproof is Required --- How Often are Glove Types Inappropriate? out of 1552 labels

30 Need New Studies to Enhance Risk Assessment and Protections Different glove types Different thicknesses of gloves Formulations and solvents Duration of tasks and exposure User input – Questions from TODAY! web.extension.illinois.edu nmda.nmsu.edu

31 Gloves Studies Ongoing Now Common glove types and thicknesses Permeation - chemical moves through protective material on a molecular level Penetration - chemical leaks through seams, pinholes, and other imperfections in the material. Expect Findings NOW! Future integration with risk assessment and labeling NPPTL

32 Protective headwear, aprons, and footwear

33 Protective Headwear Requirements Headwear is required for Dermal Toxicity Category I or II products that might involve overhead exposure. 48 labels that require headgear require long-sleeved shirt and long pants the lowest level of protection for the rest of the body. Rain suits/chemical resistant suits are often worn for orchard spraying where not only the head but the entire back is wet from exposure.

34 Apron Requirements for Mixing, Loading or Repairs A chemical-resistant apron is required for certain products with Dermal Toxicity Category I or II and/or Skin Irritation.

35 Protective Footwear Require ments

36 Protective Eyewear

37 Protective Eyewear Requirements Protective eyewear is required for Toxicity Categories I and II

38 Respiratory Protection cdc.gov

39 Respirator Requirements Require Respirator

41 Federal Dialogue – Looking to the Future your input can help Certified garments – Levels 1, 2, 3 based on ISO and ASTM standards Certified gloves – Levels 1, 2, 3 based on permeation testing, revised standards and performance specifications No change – Clarify language on labels Certified garments – Levels 1, 2, 3 based on ISO and ASTM standards Certified garments – Levels 3 based on ISO and ASTM standards worn over protective clothing required for that product

42 Read the Label Carefully for Appropriate PPE! Consider other Health Implications
