W. R. Grace & Co.'s answers to the plaintiffs' interrogatories in Williams v. National Gypsum Company, U.S. District Court for Nebraska (86-0-714), served on October 15, 1987 and certified by Merrie E. Schippereit of Grace's Construction Products Division. Because the plaintiff alleged exposure to Zonolite Mono-Kote fireproofing at one Omaha building, Grace limits its answers to Mono-Kote MK-1 and MK-3; the Product Appendix (pp. 43–45) gives their composition, dates, plants, use and packaging.
