Exposure controls

Personal protective equipment:

General protective and hygienic measures: The usual precautionary measures are to be adhered to when handling chemicals.

Respiratory protection: In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use self-contained respiratory protective device.

Recommended filter device for short term use: Filter P3

Protection of hands: Wear gloves for protection against mechanical hazards according to EN 388.

Use gloves of stable material (e.g. Nitrile) - if necessary tricoted to improve the wearability.

After use of gloves apply skin-cleaning agents and skin cosmetics. 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:

EN 388: Minimum requirements for efficiency level 1 for all groups.

Butyl rubber, BR

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.

Recommended thickness of the material: 0.35 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: Butyl rubber, BR

Nitrile rubber, NBR

Not suitable are gloves made of the following materials: cloth gloves

Eye protection: safety glasses
