Advise <br /> Authorities if spillage has entered water course or sewer or has <br /> contaminated soil or vegetation. <br /> 6.3 Methods and materials for Caution -spillages may be slippery. Contain spillages with sand, <br /> containment and cleaning up earth or any suitable adsorbent material. Transfer to a container <br /> for disposal or recovery. <br /> 6.4 Reference to other sections See Also Section 8. <br /> SECTION 7: HANDLING AND STORAGE <br /> 7.1 Precautions for safe handling Avoid contact with eyes, skin and clothing. <br /> Avoid generation of mist. Provide adequate ventilation. <br /> Emergency shower and eye wash facilities should be readily <br /> available. <br /> See Also Section 8 <br /> 7.2 Conditions for safe storage, Keep at a temperature not exceeding (°C): 50 <br /> including any incompatibilities Do not allow material to freeze. <br /> Provide an adequate bund wall. <br /> Unsuitable containers: Aluminium <br /> See Also Section 10. <br /> 7.3 Specific end use(s) See also Annex to the extended Safety Data Sheet. <br /> SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION <br /> 8.1 Control parameters <br /> -- - - - - - <br /> SUBSTANCE. Occupational Exposure Limits <br /> Silicic acid, sodium salt No Occupational Exposure Limit assigned. <br /> An exposure limit of 2 mg/m3 (15 min TWA) is recommended by analogy <br /> with sodium hydroxide (UK EH40). <br /> 8.2 Exposure controls Wear protective equipment to comply with good occupational <br /> hygiene practice. Do not eat, drink or smoke at the work place. <br /> 8.2.1 Appropriate engineering Engineering methods to prevent or control exposure are <br /> controls preferred. Methods include process or personnel enclosure, <br /> mechanical ventilation (dilution and local exhaust), and control of <br /> process conditions. <br /> 8.2.2 Personal Protection <br /> Respiratory protection Respiratory protection not normally required. Advice on <br /> respiratory protective equipment is given in the HSE (Health and <br /> Safety Executive) publication HS(G)53. <br /> Eye/face protection Chemical goggles (EN 166). <br /> Skin protection Wear suitable protective clothing and gloves. Plastic or rubber <br /> gloves. For example EN374-3, level 6 breakthrough time <br /> (>480min). Wear suitable overalls. <br /> 8.2.3 Environmental Exposure The primary hazard of sodium silicate is the alkalinity.
