What it shows
GAF dates its knowledge of the hazards to "approximately 1964," citing Selikoff (Nos. 17, 47), and Ruberoid's first warnings to about 1965. Its answers say Calsilite ended in mid-1970 (Nos. 8, 10, 45), while No. 25 says an asbestos-free Calsilite was introduced in July or August 1971 and dropped that year.
