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.
Vermiculite
The vermiculite deposit at the mine in Libby, Montana, was (and is) heavily contaminated with asbestos. Numerous people were knowingly exposed to the harmful dust of vermiculite that contained asbestos. Unfortunately, the mine had been operating since the 1920s, and environmental and industrial controls were virtually non-existent until the mine was purchased by the W.R. Grace Company in 1963. Yet, knowing the human health risks, the mining company still continued to operate there until 1990. Consequently, many of the former miners and residents of Libby have been affected and continue to suffer health problems. Over 400 people in the town have died from asbestos-related disease due to contamination from vermiculite mining from nearby Zonolite Mountain, where soil samples were found to be loaded with fibrous tremolite (known to be a very hazardous form of asbestos), and countless others there who insulated their homes with Zonolite have succumbed to asbestos-related diseases, most of whom never were employed in environments where asbestos was an issue.
