Armley asbestos disaster
On 20 July 1982, Yorkshire Television broadcast the documentary "Alice - A Fight For Life", predominantly the story of Alice Jefferson, who had worked at the Acre Mill asbestos factory in Hebden Bridge for just nine months when she was 17 years old. Thirty years later she was diagnosed with mesothelioma and given only six months to live. The documentary was also an "exposé on the workings of the asbestos industry." Its broadcast resulted in £60 million being knocked off T&N's share price overnight, headlines in the national newspapers, and the setting up of a government enquiry. Within ten days the government had halved the legal limit for asbestos dust in the workplace. In 1988 Yorkshire Television picked up the "Yorkshire Evening Post" story and produced a second critical investigation focusing on the pattern of deaths in Armley, and contradicting the government's reasons for refusing an inquiry. Called "Too Close to Home", it was broadcast as part of the "First Tuesday" documentary series on 6 December 1988.
Mesothelioma
Commercial asbestos mining at Wittenoom, Western Australia, took place from 1937 to 1966. The first case of mesothelioma in the town occurred in 1960. The second case was in 1969, and new cases began to appear more frequently thereafter. The lag time between initial exposure to asbestos and the development of mesothelioma varied from 12 years 9 months up to 58 years. A cohort study of miners employed at the mine reported that 85 deaths attributable to mesothelioma had occurred by 1985. By 1994, 539 reported deaths due to mesothelioma had been reported in Western Australia.
