Exposure controls / personal protection

Additional information about design of technical facilities: Technical measures and the application of adequate working methods take priority over the use of personal protection equipment.

Control parameters: Ingredients with limit values that require monitoring at the workplace: Not required.

Exposure controls:

Personal protective equipment: General protective and hygienic measures: Do not eat, drink, smoke or sniff while working.

Respiratory protection: If technical suction or ventilation measures are not possible or are insufficient, protective breathing apparatus must be worn. The filter class must be suitable for the maximum contaminant concentration (gas/vapour/aerosol/particulates) that may arise when handling the product. If the concentration is exceeded, a self-contained breathing apparatus must be used!

Protection of hands: Tested protective gloves are to be worn. When handling chemical substances, chemical protective gloves must be worn with CE label including a four digit code. Type of chemical protective gloves to choose depends on the concentration and quantity of dangerous substances as well as on work place specifications. In the cases of special applications, it is recommended to check the chemical resistance with the manufacturer of the gloves. The glove material has to be impermeable and resistant to the product/ the substance/ the preparation.

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.

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.

Eye protection: Safety glasses

Body protection: Protective work clothing

Limitation and supervision of exposure into the environment: Dumping into the environment must be prevented.

Stability and reactivity

1. Reactivity: The product is stable under standard conditions (temperature, pressure) of storage and handling.
