Enclosed is the current MSDS for PVC Compound. Regarding your question on the hazards of the listed ingredients, Vista's experience indicates that handling of PVC Compound under anticipated use conditions does not create exposures to these additives. These additives are encapsulated in the PVC matrix. We are currently modifying our PVC Compound MSDS to more clearly reflect this. Regarding your deficiency notice, I believe the MSDS to satisfy all the indicated areas. The health hazards of PVC are indicated in Section 5 of the MSDS. There are no known specific medical conditions that would be aggravated by exposure to PVC dust, and PVC is not a carcinogen as defined in the Hazard Communication Standard. Please call me at 713/531-3445 if you have further questions on the above. Sincerely, Thomas G. Grumbles, C.I.H. Environmental Quality Manager ajo Enclosures
