Welcome to harmfuldust.com - hazardous dust
Find out more about chromium (VI) compounds (calcium chromate) in the workplace, especially when using currently available insulating materials for thermal insulation of turbines, engines and generators.



Since 2020, harmfuldust.com has been reporting on carcinogenic chromium(VI) compounds on insulated hot components. Calcium oxide and sodium oxide from high-temperature insulation materials can react with chromium-alloyed steel above about 300 °C to form calcium chromate and sodium chromate. These are released as chromate-containing dusts and fibers during maintenance and removal, and also during normal operation.
The work “History Repeats Itself. Chromium(VI) in High-Temperature Insulation and the Parallels to Asbestos” shows how the history of asbestos can repeat itself on these installations. It is available for download in four languages, and every Thursday one chapter is published here as a separate post.
