No special measures required.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
No further data; see section 7.
Protective gloves. Use gloves tested and approved under appropriate government standards such as NIOSH (US) or EN374 (EU). 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.
Tightly sealed goggles conforming to EN166.
Use suitable respiratory protective device in case of insufficient ventilation.
Protective work clothing. Body protection must be chosen depending on product properties, activity and possible exposure.
