Material Safety Data Sheet
（Sodium hydrogen carbonate）
product/ the preparation/ the chemical mixture.
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.
-Skin and body protection ： Wear appropriate protective gloves and clothing to prevent skin
exposure 。
-Eye protection: Use chemical safety goggles and/or full face shield. Maintain eye wash fountain
and quick-drench facilities in work area.
-Environment exposure controls: No information available.
