P.0. Box 1460 Salina, KS 67402 VIS1A Dear Mr. Norris: Enclosed are drum labels for LPA Solvent. As we discussed, these labels are based on the language we believe to comply with the OSHA Hazard Communication Standard. While we are providing this for your use on LPA purchased by you and repackaged, it is your responsibility to determine their suitability based on your own hazard determination. Sincerely, Thomas 6.

Grumbles June 30, 1989 HAZARD DETERMINATION FOR SULFONIC ACID VISTA As you are aware there had been an indication that holding sulfonic acid at an elevated temperature for extended periodsofjime could result in the formation of significant quantities q^T?enzeTi?Jl This was indicated based on analytical results found durfrlig mul Efforts to analyze products for detectable quantities of California Proposition 65 listed substances. In summary, analytical work done in Ponca City indicated unexpected levels of benzene. Upon review of the data, it appeared that the initial sample may have been held at temperatures above 100F for an extended period of time, probably greater than four hours. A second sample was run under normal conditions and no benzene was detected. However, this result caused concern regarding the potential for benzene formation during the handling and storage of sulfonic acids. To evaluate the potential exposure to benzene at normal handling temperatures, air samples were taken in the vapor spaces of product storage tanks. The results attached indicate essentially non- detectable levels of benzene. Based on these results, the known and expected handling conditions of sulfonic acids, and the nonrepeatability of the product analytical results, there appears to be no benzene formation or exposure potential. Therefore, no additional warning information is needed for our sulfonic acids. T. G. Grumbles dlj Attachment cc: Gina Lakich, Ed Sones, Jim Yates VVV 000010775
