Secondary Containment for Transformer Bund
Impervious secondary containment bunding is now a legal requirement in Australia especially around tanks, storage vessels and other plant that contains liquid that can be dangerous or hazardous to the environment.
“Bunds should be designed to contain spillages and leaks of liquids used, stored or processed above ground and to facilitate clean-up operations. As well as being used to prevent pollution of the receiving environment, bunds are also used for fire protection, product recovery and process isolation.” http://www.epa.sa.gov.au/xstd_files/Waste/Guideline/guide_bunding.pdf accessed 01/10/2014
Rhino Linings RhinoGuard 2195, a Hybrid Polyurethane, is the ideal solution for long term sealing of bund areas and protection against attack by transformer oil.
For this particular project, special cleaning techniques were developed to remove transformer oil that had already been spilled and seal the concrete prior to coating with RhinoGuard 2195. This ensured that the transformer bund would contain all spilt oil/water mixture during the remaining life of this infrastructure.
Lining bunds like this demonstrates to the EPA / State / Federal authorities that a company has made a concentrated effort to contain any leaks saving them hundreds of thousands of dollars in future possible fines.
The work was carried out by Sydney based Rhino Linings Approved Applicator Australian Protective Coatings.
