Asbestos Gasket Removal and Heat Shielding

The use of asbestos materials for exhaust gaskets, brake linings, and other heat resistant applications was extensive in machinery from the 1900s to the 1970s. Sheet gasket material commonly contained up to 70-80 percent chrysotile, or “white asbestos,” and gaskets designed for acidic environments often contained a more dangerous mineral called crocidolite, which is also known as “blue asbestos.” 

Darwin Asbestos and Demolition have conducted numerous small projects to remove suspected or verified asbestos gaskets from various machinery. Most recently this included a redundant stand by generator at HMAS Coonawarra (as shown in the image).
