Exposure controls / personal protection

Personal protective equipment:

· General protective and hygienic measures:

Keep away from foodstuffs, beverages and feed.

Immediately remove all soiled and contaminated clothing.

Wash hands before breaks and at the end of work.

Avoid contact with the eyes and skin.

Respiratory protection:

Use suitable respiratory protective device only when aerosol or mist is formed.

· Protection of hands:

Protective gloves.

Check the condition of the gloves prior to each use.

The glove material has to be impermeable and resistant to the product/ the substance/ the

preparation.

Selection of the glove material on consideration of the penetration times, rates of diffusion and the

degradation.

Preventive skin protection by use of skin-protecting agents is recommended.

· Material of gloves

The selection of the suitable gloves does not only depend on the material, but also on further

marks of quality and varies from manufacturer to manufacturer. As the product is a preparation of

several substances, the resistance of the glove material can not be calculated in advance and has

therefore to be checked prior to the application.

Fluorocarbon rubber (Viton)

Recommended thickness of the material: >= 0.7 mm

· Penetration time of glove material

EN 420: Minimum requirements for efficiency level 1 for all groups.

The exact break through time has to be obtained from the manufacturer of the protective gloves

and has to be observed.

For the mixture of chemicals mentioned below the penetration time has to be at least 480 minutes

(Permeation according to EN 374 Part 3: Level 6).

· For the permanent contact gloves made of the following materials are suitable:

Fluorocarbon rubber (Viton)

· Not suitable are gloves made of the following materials:

Butyl rubber, BR

Nitrile rubber, NBR

Leather gloves

Strong material gloves

· Eye protection:

Tightly sealed goggles

Face protection

· Body protection: Use protective suit.
