Safe storage for Sodium Hypochlorite
LINPAC Allibert is seeking to re-assure customers about the safety of its Helix range of tanks for the bulk storage of Sodium Hypochlorite. The move follows a report from the technical committee of the Chemical Plant section of the British Plastics Federation which raises concerns about the use of HDPE thermoplastic tanks for this type of application.
Roger Andrews, spokesman for the Helix division of LINPAC Allibert explains: “The report raises concerns about the use of certain types of tanks for sodium hypochlorite, raising alarm about the risk of failure and this has caused concern and confusion among customers. We are seeking to clarify the situation with both the British Plastics Federation and with our customers to reassure them about the safety of our product for this type of work. Indeed, the British Plastics Federation has clarified to LINPAC that the Federation as a whole has not considered the issue and does not have a point of view to express on it.
“We share the concerns expressed in the article published by the committee that plastic tanks that have their cylinders fabricated from sheet material are prone to attack at the welds and therefore have the potential to “catastrophically fail”. However, our helically wound tanks have no such welds and as a consequence in more than 30 years and many thousands of tanks produced we have never ever had such a failure. We work closely with our materials suppliers to ensure that the highest standards are met to ensure that our products are not in any way associated with this type of failure.”
