Zonolite Company / W. R. Grace & Co. plant at Spokane, Washington

W. R. Grace & Co.'s sworn answers in a 1987 lawsuit, Williams against National Gypsum, list Spokane, Washington, among the plants where its Zonolite Mono-Kote fireproofing was made, saying of each product that it "was manufactured at some or all of the plants listed."1 For Zonolite Mono-Kote MK-3 the answers give Spokane's approximate dates as 1959-1973; for Zonolite Mono-Kote MK-1 they say the dates of production "are not known."1 The same answers say MK-1 was "Produced by Zonolite Company from 1959," and MK-3 was produced by Zonolite Company "from 1959 to 1963" and by Grace "from 1963 until 1973"; they do not say which company ran the Spokane plant.1

Grace described both products as light beige cementitious fireproofing.1 It gave MK-1's asbestos as "approximately 11.9% short fiber Chrysotile asbestos," and MK-3's as "approximately 13.23 percent 7M" and "12.18 7R" short fiber chrysotile asbestos by weight; those figures describe the products, not Spokane's output in particular.1
