<br />MATERIAL SAFETY DATA SHEET <br /> <br />.MDow AgroSciences <br />VIKANE* GAS FUMIGANT <br /> <br />Emergency Phone: 800-992-5994 <br />Dow AgroSciences LLC <br />Indianapolis, IN 46268 <br /> <br />Effective Date: 1017/03 <br />Product Code: 91503 <br />MSDS: 000506 <br /> <br />8. EXPOSURE CONTROLS/PERSONAL PROTECTION: <br /> <br />RESPIRATORY PROTECTION: Atmospheric levels should <br />be maintained below exposure guideline. When respiratory <br />protection is required, use a NIOSH approved self-contained <br />breathing apparatus or positive-pressure airline with T t <br />auxiliary self-contained air supply. For emergency and other HAZARDOUS POL YMERIZA ION: Not known 0 occur. <br /> <br />conditions where the exposure guideline may be exceeded, /11. TOXICOLOGICAL INFORMATION: <br />use a NIOSH approved positive-pressure self-contained <br />breathing apparatus or positive pressure airline with auxiliary MUTAGENICITY: In-vitro and animal genetic toxicity studies <br />self-contained air supply. In confined or poorly ventilated were negative. <br />areas, use a NIOSH approved self-contained breathing I <br />apparatus or positive pressure airline with auxiliary self- 12. ECOLOGICAL INFORMATION: <br /> <br />contained air supply. ENVIRONMENTAL FATE: <br /> <br />These precautions are suggested for conditions where a <br />potential for exposure exists. Emergency conditions may <br />require additional precautions. <br /> <br />EXPOSURE GUIDELINE: Sulfuryl fluoride: ACGIH TL V is 5 <br />ppm TWA, 10 ppm STEL. OSHA PEL is 5 ppm TWA. <br /> <br />ENGINEERING CONTROLS: Provide general and/or local <br />exhaust ventilation to control airborne levels below the <br />exposure guidelines. Lethal concentrations may exist in <br />areas with poor ventilation. <br /> <br />RECOMMENDATIONS FOR MANUFACTURING, <br />COMMERCIAL BLENDING, AND PACKAGING <br />WORKERS: <br /> <br />SKIN PROTECTION: No special skin protection should be <br />needed. Skin contact with the liquid may cause freeze <br />damage if the liquid is confined to the skin; do not wear <br />gloves or rubber boots. <br /> <br />EYE PROTECTION: Use chemical goggles. <br /> <br />APPLICATORS AND ALL OTHER HANDLERS: Refer to <br />the product label for personal protective clothing and <br />equipment. <br /> <br />"Trademark of Dow AgroSciences <br /> <br />19.
