10、ishing Media:Alcohol foam, carbon dioxide. DO NOT USE dry chemical, multipurpose dry chemical, or loaded stream media because of explosion potential due to reactivity of basic compounds in these extinguishing media. Special Information:In the event of a fire, wear full protective clothing and NIOSH-
11、approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. 6. Accidental Release Measures Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. S
12、pills: Clean up spills in a manner that does not disperse dust into the air. Use non-sparking tools and equipment. Reduce airborne dust and prevent scattering by moistening with water. Pick up spill for recovery or disposal and place in a closed container. Evacuate area of all unnecessary personnel.
13、 US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities.7.

Exposure Controls/Personal Protection Airborne Exposure Limits:-OSHA Permissible Exposure Limit (PEL): 0.25 ppm, 1 mg/m3 (TWA) -ACGIH Threshold Limit Value (TLV): 0.1 ppm, (TWA), Sensitizer, A4 - Not classifiable as a human carc
17、inogen. Ventilation System:A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into t
18、he general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details. Personal Respirators (NIOSH Approved):If the exposure limit is exceeded, and engineering controls are not feasible, a full-face piece respirator with
19、 an organic vapor cartridge and particulate filter (NIOSH type N100 filter) may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids, g
20、lycerine, etc.) are present, use a NIOSH type R or P particulate filter. For emergencies or instances where the exposure levels are not known, use a full-face piece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
21、Where respirators are required, you must have a written program covering the basic requirements in the OSHA respirator standard. These include training, fit testing, medical approval, cleaning, maintenance, cartridge change schedules, etc. See 29CFR1910.134 for details. Skin Protection:Wear impervio
22、us protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact. 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 wo
