678 Semi-refractory (Johns-Manville)

678 Semi-Refractory was a Johns-Manville cement; in sworn answers in a 1970 lawsuit, J-M listed it as "#678 SEMI-REF. CEMENT."1,2 An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, gives it as made from 1941 to 1969.2

A 1990 EPA notice that published what Manville reported gives figures only for a whole group of "Asbestos-Binder" cements, 678 among them, alongside Superex and 85% Magnesia.3 For that group it says the cements were produced from 1930 to 1973 and contained 10 to 100% asbestos, with up to 30% each of diatomaceous earth, clay, portland cement and mineral wool.3 It describes the group as off-white to grey in color, packaged in cans or pails.3

J-M swore in two lawsuits that on or about December 15, 1964, it began putting a precautionary label on the cement.4,5 The label began "CAUTION THIS PRODUCT CONTAINS ASBESTOS FIBER," and said that where adequate ventilation control was not possible, workers should wear respirators approved by the U.S. Bureau of Mines.1,5
