8.3 Personal protection:
General protection and hygiene measures: Avoid contact with skin and eyes. Take off immediately contaminated clothing. Observe usual precaution measures when handling chemicals.
Respiratory Protection: not required.
Eye Protection: Safety goggles.
Hand Protection: Protective gloves. 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
· 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.
· Penetration time of glove material
The exact break through time has to be found out by the manufacturer of the protective gloves and has to be observed.
· For the permanent contact gloves made of the following materials are suitable: Recommended thickness of the material: 0.7 mm
Fluorocarbon rubber (Viton)
Value for the permeation: Level ≥ 480 min.
· As protection from splashes gloves made of the following materials are suitable: Recommended thickness of the material: 0.6 mm
Natural rubber, NR
Value for the permeation: Level 120min.
Skin protection: Not required.
