MATERIAL SAFETY DATA SHEET <br /> 000002684/F/USA - P-0007.300E <br /> Approval Date: 04/03/1998 <br /> Print Date: 04/04/1998 <br /> Page 6 <br /> ------------------------------------------ --------------------------------------- <br /> OSHA (USA) Permissible Exposure Limit (PEL - 1971 Table Z-1 Values) : <br /> Sulfur dioxide: 2 ppm TWA, 5 ppm STEL <br /> Ventilation: Good general ventilation (typically 10 air changes per hour) <br /> should be used. Ventilation rates should be matched to conditions. <br /> Supplementary local exhaust ventilation, closed systems, or respiratory <br /> protection may be needed in special circumstances such as poorly ventilated <br /> spaces, evaporation from large surfaces, spraying, heating, etc. <br /> Respiratory Protection: <br /> Part A: If engineering controls do not maintain airborne concentrations <br /> below recommended exposure limits, an approved respirator must be worn. <br /> Respirator type: Organic vapor. If respirators are used, a program should be <br /> instituted to assure compliance with OSHA Standard 29 CFR 1910. 134. <br /> Part B: If engineering controls do not maintain airborne concentrations <br /> below recommended exposure limits, an approved respirator must be worn. <br /> Respirator type: Acid gas. If respirators are used, a program should be <br /> instituted to assure compliance with OSHA Standard 29 CFR 1910. 134. <br /> Part C: If engineering controls do not maintain airborne concentrations <br /> below recommended exposure limits, an approved respirator must be worn. <br /> Respirator type: High efficiency particulate aerosol (HEPA) . If respirators <br /> are used, a program should be instituted to assure compliance with OSHA <br /> Standard 29 CFR 1910. 134. <br /> Eye Protection: <br /> Part A & Part B: Wear safety glasses with side shields (or goggles) . <br /> Part C: Wear safety glasses with side shields (or goggles) and a face <br /> shield. <br /> Skin Protection: Wear impervious gloves and protective clothing appropriate <br /> for the risk of exposure. <br /> Recommended Decontamination Facilities: Eye bath, washing facilities, safety <br /> shower <br /> ------------------------------------------------------------------------------ <br /> 9.
