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

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


CEN Protective clothing classification

Category III

Liquid tight

Spray tight

Particle tight

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.


Examples ‘protective clothing’

PPE Type 6 & 5 & 4

Cat. I (no PPE)

PPE Type 6 & 5 & 4

No EN mark (not certified, no PPE)

PPE Type 5 & 6


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.


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.


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


Masks on the market

EN certified mask P1 NO CE/EN mark, i.e. • no certified mask • no guarantied efficacy • perceived protection

Avoid overprotection!


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.


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.


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.



• 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.



• 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.



• 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.


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.


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.


PPE in closed and filtered cabins

Work clothing during application in cabin. Putting

on gloves if leaving the cabin.
