A MiniContainment can also be applied in (large-scale) industry.
Often, the gaskets between the flanges that connect two pipes together contain asbestos. With a MiniContainment these gaskets can be removed quickly and efficiently, without closing down a working area for a long time.
In 2015 we removed a valve at the Chemelot site that was attached to a pipe through an asbestos gasket. Over the years the gasket was corroded to the flange. With a scraper (a kind of chisel), the seal of the flange had to be removed. During this removal, we measured the air (with a gold-coated filter) outside the MiniContainment. The measurement was negative, which determined that no fibers were released during the decontamination in the MiniContainment. The final inspection after the removal in the MiniContainment also gave a negative result: no asbestos fibers were present in the MiniContainment.
Below you can find two videos that show the removal of asbestos containing gaskets in large-scale industry. The first shows a an example of asbestos removal. The second is a testimonial of the HSEQ (Health, Safety, Environment and Quality) employee who was involved in the Chemelot MiniContainment project.
