MATERIAL SAFETY DATA SHEET <br /> 000006496/F/USA - P-0007.207D <br /> Approval Date: 05/14/1998 <br /> Print Date: 05/16/1998 <br /> Page 6 <br /> ------------------------------------------------------------------------------ <br /> Part C: Keep away from heat and flame. Keep from contact with oxidizing <br /> materials. Use with adequate ventilation. <br /> Storage: <br /> Part A, Part B & Working solution: Keep container tightly closed. Keep away <br /> from incompatible substances (see Incompatibility section) . <br /> Part C: Keep container closed. Keep away from incompatible substances (see <br /> Incompatibility section) . <br /> ------------------------------------------------------------------------------ <br /> 8. EXPOSURE CONTROLS/PERSONAL PROTECTION <br /> Exposure Limits: <br /> ACGIH Threshold Limit Value (TLV) : <br /> Sodium bisulfate: 5 mg/m3 TWA <br /> Acetic acid: 10 ppm TWA; 15 ppm STEL <br /> OSHA (USA) Permissible Exposure Limi`, (PEL - 1971 Table Z-1 Values) : <br /> Acetic acid: 10 ppm TWA <br /> Ventilation: <br /> Part A, Part B & Working solution: Good general ventilation (typically 10 <br /> air changes per hour) should be used. Ventilation rates should be matched to <br /> conditions. <br /> Part C: Use process enclosures , local exhaust ventilation, or other <br /> engineering controls to maintain airborne levels below recommended exposure <br /> limits. <br /> Respiratory Protection: <br /> Part A, Part B & Working solution: None should be needed. A respirator <br /> should be worn if hazardous decomposition products are likely to be or have <br /> been released. Respirator type: organic vapor/acid gas/ammonia cartridge. <br /> If respirators are used, a program should be instituted to assure compliance <br /> 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: full-face organic vapor cartridge. If respirators are used, <br /> a program should be instituted to assure compliance with OSHA Standard 29 <br /> CFR 1910. 134. <br />
