Bulk tank cleaning case study


Courtesy of Progressive Technical Services Ltd

We were contacted by a West Midlands based chemical manufacturer that required a large number of their tanks to be cleaned and decommissioned prior to demolition. The cleaning required a combination of non-man entry and man entry tank cleaning techniques an area that Progressive excel in. After several site visits and an audit of Progressive’s Health, Safety & Environmental procedures and documentation the company was awarded the contract for the cleaning of eighty one tanks ranging from small mixing tanks to larger chemical and caustic soda storage vessels. As some tanks only required a wash out PTS utilised its range of tank cleaning machines and high head pumps to complete the work. A tank was dedicated for all waste that was produced. Other tanks required a combination of non man entry and man entry to dig out material that had set on the shells and floors. Using breathing apparatus and all in one chemical suits operators successfully removed over one hundred tonnes of material from the tanks. Confined Space Entry was strictly controlled by the site supervisor and used our CSE & BA control board to ensure operators worked comfortably within their limits. Once all tanks had be cleaned, all were gas freed and certification issued. Over one hundred and thirty tonnes of waste in IBC’s and tankers was safely removed for disposal following the current legislation.
