Fire Fighting Measures Fire: Not considered to be a fire hazard. Explosion: Not considered an explosion hazard, but sodium carbonate may explode when
10、applied to red-hot aluminum. Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire. Special Information: Use protective clothing and breathing equipment appropriate for the surrounding fire. 6. Accidental Release Measures Ventilate area of leak or spill. Wear appropriat
11、e personal protective equipment as specified in Section 8. Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal. 7. Handling and Storage Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against
12、 physical damage. Isolate from inpatible substances. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product. 8. Exposure Controls/Personal Protection Airborne Exposure Limits: None establi
13、shed. Default to Particulates Not Otherwise Regulated OSHA (PEL/TWA): 15 mg/m3 (total dust); 5 mg/m3 (resp fraction) Ventilation System: - . - .word.zl. A system of local and/or general exhaust is remended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferre
14、d because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Remended Practices, most recent edition, for details. Personal Respirators (NIOSH Approved): For co
15、nditions of use where exposure to the dust or mist is apparent, a half-face dust/mist respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in
16、 oxygen-deficient atmospheres. Skin Protection: Wear protective gloves and clean body-covering clothing. Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area. 9. Ph
