Asbestos Containing Materials (ACMs)

Asbestos has been common in buildings since the mid-19th century and was used extensively until its eventual ban in 1999. Over this period, it is estimated that over 3000 different products were manufactured containing asbestos fibres. Importation of asbestos to the UK between 1940 and 1998 exceeded 5 million tonnes.

We have provided a brief summary of asbestos materials with a brief description of location/use, asbestos type, asbestos content and approx. dates used.
