### 8 Exposure controls and personal protection

· Components with limit values that require monitoring at the workplace: 1308-38-9 chrome oxide REL TLV 0.5 mg/m3 as Cr 0.5 mg/m3 as Cr 1344-28-1 non-fibrous alumina PEL REL TLV 15* 5** mg/m3 *total dust **respirable fraction Short-term value: 1.5* mg/m3 *as resprable fraction 1* mg/m3 *as respirable fraction 1308-31-2 chromite REL 0.001 mg/m3 as Cr(VI), 10-hr TWA
· Personal protective equipment: · General protective and hygienic measures: Keep away from foodstuffs, beverages and feed. Wash hands before breaks and at the end of work. Avoid contact with the eyes and skin. · Breathing equipment:

NIOSH approved respirators should be used if dust i s present. A respiratory protection program should be implemented if exposures exceed OSHA PELs .
· Protection of hands:

Protective gloves recommended The glove material has to be impermeable and resist ant to the product/ the substance/ the preparation. Due to missing tests no recommendation to the glove material can be given for the product/ the prepara tion/ 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 o f 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 appli cation. · Penetration time of glove material The exact break trough time has to be found out by the manufacturer of the protective gloves and has t o be observed.
