“50 Min”, “Song Of The Canary”, Eastman Color, Red Fade, possibly incomplete at tail, but should compose the majority of the film,

“The film is a powerful story of the hidden dangers in the American workplace – a story of men working in a pesticide company in California. During the making of this film, the furor set off by the filmmaker’s discoveries about certain practices in the Ag Chem Department of Occidental Chemical Company, at a plant in California, resulted in a nationwide ban on the production of the pesticide DBCP. The filmmakers discovered that every one of the plant’s employees involved in the production of that chemical had become sterile. Other abuses are also brought to light. In 1977, 60 workers at a chemical production plant in California making the pesticide DBCP (1,2-dibromo-3-chloropropane), were found to be sterile. The EPA prohibited DBCP use in the United States in September 1977. DBCP is a potent carcinogen and perhaps the most powerful testicular toxin ever made”

“he Song of the Canary is a 1978 American occupational health documentary film directed by Josh Hanig and David Davis. The film documents the Occidental Petroleum plant in Manteca, California and the scandal in which employees became sterile after being exposed to the pesticide DBCP.[1][2] It also features interviews with workers over the use of guinea pigs, and health and safety regulations.”
