11 Risk assessment: Predictive Operator Exposure Models (POEMs) German POEM UK POEM Basis: T-shirt & shorts (no PPE) Basis: Polyester/cotton coverall (no PPE) 11

12 Risk assessment: Acceptable Operator Exposure Level (AOEL) NOAEL (No observed adverse effect level in animal tox studies) /100 = AOEL (Acceptable Operator Exposure Level) 12

13 Risk assessment: AOEL and PPE If operator exposure < AOEL, then no PPE is required If operator exposure > AOEL, then PPE is required (exposure mitigation) so that operator exposure < AOEL Protective clothing Protective gloves Face shield Goggles Mask Boots Apron Cuffs 13

14 Risk assessment: Read the label Hazard characterization Intrinsic properties of the compound(s): Outcome of toxicological evaluations Old EU System Pictograms Risk (R) & Safety (S) phrases New CLP (GHS) System Pictograms Hazard (H) & Precautionary (P) Statements Risk assessment Daily exposure compared to the relevant toxicological reference value Acceptable Operator Exposure Levels (AOEL) Risk = f (hazard x exposure) Personal Protective Equipment (PPE) Recommendation on pesticide label 14

15 Terminology: Personal Protective Equipment (PPE) The performance of PPE is standardised. PPE is certified by notified body (4 digit number) according to ISO (International Organisation for Standardisation) CEN (European Committee for Standardisation) Country Standardisation Organisation, e.g. Germany: DIN (Deutsche Industrie Norm) Over the shelf WORK CLOTHING (coverall) or long sleeved shirts and trousers are not considered as PPE 15

16 Protective clothing: Label text No information on the label: Label text: - No Risk (R) & Safety (S) phrases - No Hazard (H) & Precautionary (P) Statements Over the shelf polyester/cotton work clothing (not certified) is sufficiently protective - S 36 Wear suitable protective clothing - P280 Wear protective gloves/protective clothing - P281 Use personal protective equipment as required CEN/ISO/HZN protective clothing is required 16

17 Categories of PPE in the EU Defined in European Directive 89/686/EEC: PPE category I: to protect against mechanical actions, cleaning materials of weak action and easily reversible health effects. PPE category II: products which do not fall into category I & III. PPE category III: to protect against risks which may seriously or irreversibly harm health. PPE for the mix/loading and application of pesticides must be category III 17

18 CEN Protective clothing classification Category III Liquid tight Spray tight Spray tight (limited) Particle tight 18

19 ISO and DIN Protective clothing classification Worldwide: ISO 27065:2011: Protective clothing Performance requirements for protective clothing worn by operators applying liquid pesticides: Level 1: Polyester/cotton clothing of good performance; Level 2: Polyster/cotton clothing with high quality repellent finish, similar to non woven fabric EN type 6; Level 3: Impervious material, similar to non woven materials EN type 3. Germany: DIN 32781: Protective clothing Protective suits against pesticides: DIN is about equivalent to ISO 27065:2011 level 1 clothing. 19

20 Examples protective clothing PPE Type 5 & 6 Cat. I (no PPE) PPE Type 6 & 5 & 4 PPE Type 6 & 5 & 4 No EN mark (not certified, no PPE) 20

21 Gloves Gloves with woven parts should not be used. Gloves with a CE mark hammer means mechanical resistant, but not chemical resistant. Gloves without CE mark means no EN/ISO certified gloves (perceived protection). Chemical protective gloves EN 374:

22 Recommended chemical protective gloves See Recommendation: Personal Protective Equipment (PPE) For mixing/loading of concentrated pesticides: multiple use gloves from Ansell: Sol-vex Premium ; Solvex from Ansell. For diluted pesticides, e.g. application, nozzle repair, etc: single use gloves from Ansell: Touch N Tuff

23 Wash the gloves before taking them off Wash gloves each time with water before taking them off. Washing prolongs the life time of gloves. If gloves are not washed, products can permeate to the inner side of gloves and contaminate the hands. 23

24 How to take off reusable gloves correctly 1. Pull one glove off half way. 2. With hand still in fist pull the other glove off the hand as far as the wrist. 3. Put ungloved thumb inside top of second glove. 4. Lift hand out and hold gloves by inside surfaces only. 24

25 Check gloves for leaks before wearing Your hands must be clean and dry before wearing gloves. Check your gloves for any visible weakness such as lumps, pinholes and thin patches. Check your gloves for leaks: trap air in the glove by rolling up and squeeze inflated glove to test for leaks. 25

26 Dust/mist/vapour mask Disposable dust /mist mask CE Mark: 149:2001+A1:2009 Reduction of exposure by a Assigned Protection Factor (APF): FFP1: 4x FFP2: 10x (normally used) FFP3: 20x FFP = Filtering Face Piece Risk assessment in Germany (2010): only 8 out of 644 pesticides need a P2 filter. Reduction of exposure in risk assessments: 90%. Reusable dust /mist/vapour mask Against organic vapour (A1, A2, A3) + dust/mist (P1, P2, P3), e.g. A2P3 (normally used) Risk assessment in Germany (2010): only 6 out of 644 pesticides need a vapour/particle filter A1P2. Out of the 6 is no pesticide for field crops and only 1 acaricide in vineyards. Reduction of exposure in risk assessments: 90%. 26

27 Masks on the market EN certified mask P1 NO CE/EN mark, i.e. no certified mask no guarantied efficacy perceived protection 27

28 Wear trousers over boots 28

29 Other PPE Face shield Boots Apron Cuffs Goggles (EN 166:2002-4) Safety glasses (EN 166) 29

30 During the season Different treatments, different pesticides: What PPE to wear? Shall I change PPE with each product? Protection (according to pesticide label) Work clothing Type 6 (CEN) Level 1-2 (ISO) Type 4 (CEN Liquid tight Type 3 (CEN) Level 3 (ISO) 30

31 What PPE to wear?

32 Avoid overprotection! 32

33 Washing and cleaning of PPE Wash and clean protective equipment after each working day. Collect and wash protective clothing separate from private clothing. Follow the washing instruction of the manufacturer. 33

34 Washing and cleaning of PPE Reusable coverall: follow washing instruction of the manufacturer. Wash highly contaminated clothing (coverall and caps) twice. Gloves: wash them with water each time before you take them off. Boots: Wash them with water after each working day. Face shield/goggles: Wash it with water after each working day. Masks: Clean the inside of the mask with a wet towel (mild detergent). Do not wash it under water. Apron: Wash it with water after each working day. 34

35 Regular replacement of PPE Buy and replace protective equipment (coverall, gloves, boots, face shield, respirator, goggles, apron) at a regular basis. Replace torn clothing and damaged protective equipment immediately. 35

36 Regular replacement of PPE Coverall or jacket/trousers Replace disposable coveralls after each working day. Do not wash and reuse them. Replace reusable coveralls after they are torn or damaged, but at the latest after the maximum number of washings indicated on the coverall label. 36

37 Regular replacement of PPE Gloves Chemicals can continue to permeate whether the glove is being worn or not, so avoid keeping them for long periods. If the glove is contaminated, looks dirty, smells of chemical, or if you are unsure about its protection, then dispose it safely. In doubt get a new pair. Replace reusable gloves at the latest after 1 season. 37

38 Regular replacement of PPE Check the expire date of filters. If filters or masks are damaged, replace them. Change the mask against vapour + mist: A2P3 if there is the slightest smell, taste or irritation (warning properties of pesticide); If breathing resistance is increased. Change the masks against mist and dust: P2 or P3: If breathing resistance is increased; If you cannot achieve a good fitting of the mask, replace it. 38

39 Storage of PPE Keep PPE separate from private clothing. Store the protective equipment on a clean and dry place. Keep an inventory of protective equipment. Keep at least two sets of all protective equipment: one in use, and one on store. Keep the protective equipment in use and the one on store separate. 39

40 PPE in closed and filtered cabins Closed and filtered cabins of tractors and self-propelled sprayers offer the opportunity to replace PPE during the application phase of pesticides. Since 2009 cabins are standardised: EN
