Risk assessment: Acceptable Operator Exposure Level (AOEL)
NOAEL (No observed adverse effect level in animal tox studies)
AOEL (Acceptable Operator Exposure Level)
/100 =
Protective equipment for handling pesticides November 2013 in Zagreb 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

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

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

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

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 32781 is about equivalent to ISO 27065:2011 level 1 clothing.

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: 2003.
Protective equipment for handling pesticides November 2013 in Zagreb 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 37-900;
• Solvex 37-695 from Ansell.
For diluted pesticides, e.g. application, nozzle repair, etc: single use gloves from Ansell:
• Touch N Tuff 92-600.

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.
Protective equipment for handling pesticides November 2013 in Zagreb 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.

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.

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
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 8 out of 644 pesticides need a P2 filter. Reduction of exposure in risk assessments: 90%.
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%.
FFP = Filtering Face Piece

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.

clothing.
• Store the protective equipment on a
clean and dry place.

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 15695.
