Understanding Biocidal Copper and Silver and Article 95

There are a number of companies selling elemental silver (EC No. 231-131-3, CAS No. 7440-22-4) as part of copper and silver ionisation systems for controlling Legionella and other bacteria in water systems that are not on the Article 95 list for elemental silver. At present, these ionisation companies would need to purchase their elemental silver in the correct Product Type (PT) from members of the silver task force that are on the Article 95 list, or from a company in a supply chain with members of the silver task force that are on the Article 95 list.

There are only 2 companies, other than ProEconomy, that are on the Article 95 list for elemental silver under PT 2 (uses include bathing water, air-conditioning systems, and water distribution systems) and PT 5 (drinking water).

Once elemental silver is approved as an active substance under the BPR, the need to comply with the product authorisation rules of the BPR arise. One effect of these rules is that a company supplying elemental silver as a biocidal product would need to demonstrate that its source of elemental silver is technically equivalent to the sources of elemental silver approved under the BPR. At the moment, there is only ProEconomy and one other company whose elemental silver is being reviewed under the BPR.

The majority of the ionisation systems used in the UK are installed within healthcare premises and therefore are paid by the taxpayer. ProEconomy are concerned about the financial implications associated with paying for non-compliant ionisation systems that will have to be shortly removed. ProEconomy would like to make the UK healthcare industry aware of this compliance situation as non-compliant ionisation companies may not be keeping their customers apprised.

ProEconomy are also concerned about the rising cost of elemental silver as a biocide which may fluctuate over time. ProEconomy has not increased the price of its elemental silver and guarantees the stability of its elemental silver price.

We hope that non-compliant ionisation companies have made their potential clients aware of the instability of their elemental silver price and the potential removal of their silver ionisation products from the market when the product authorisation obligations arise, as mentioned above.

The new Orca at Churchill hospital proves extremely effective 

 

The Orca copper and silver ionisation system at Churchill Hospital (part of the John Radcliffe in Oxfordshire) was installed at the beginning of this year and has completely eradicated Legionella at the site.

Pre-commissioning samples at 14 points showed a Legionella contamination percentage of 64.2%. This percentage has been reduced to 0% post Orca installation. 

It is another success story for the Orca and adds to the weight of data that proves just how effective our system is. For more information and to see the results for yourself please contact us at byron@proeconomy.com.

After the great results seen at the Churchill unit, John Radcliffe hospital has installed a new Orca unit at the Womens Centre within their main building and we hope to install a further large system soon that will treat the rest of their site.

ProEconomy are included for copper and silver on the Article 95 BPD listing.

As of the 1st of September any company that uses a biocide (any substance used as a biocidal agent including chemicals such as chlorine dioxide) that is not on the 'Article 95 list for the product type(s) to which the product belongs' will be withdrawn from the European marketplace. Click this link to view the announcement on the ECHA (European Chemical's Agency) website: http://echa.europa.eu/biocides-2015.

ProEconomy are founding members of the copper and the silver task forces and are therefore included in the Article 95 list for both copper and for silver. This means that ProEconomy will not be affected by the Biocidal Products Directive September 2015 deadline and will be able tocontinue to use their product to successfully control Legionella and Pseudomonas bacteria in water systems throughout the UK.

If you search for ProEconomy on the article 95 list you will find our inclusion on product types 5 and 11 (bathing and drinking water) for both copper and silver. 

The articvle 95 list is downloadable online on the ECHA website: http://echa.europa.eu/information-on-chemicals/active-substance-suppliers or can be downloaded by clicking the link below:

Derogation for copper as a biocide has been granted by the European Commission.

HSE recognised copper as an essential element in the control of Legionella in hot and cold water systems and ProEconomy would like to thank them for their support.

Derogation has been granted for product types 2 (allowing copper as a biocide for human use) and product types 5 (allowing copper as a biocide for use in drinking water).

The essential use derogation will last until December 2014.

Companies that use copper as a biocide have formed the copper task force, which will have submitted the application for annex listing in the biocidal products directive by the summer. Once this application for annex listings is submitted the derogation will become obsolete and copper can continue to be used indefinitely.

ProEconomy prepared the essential use derogation application for the HSE and we have been at forefront of the derogation process. Moreover, as a founding member of the copper task force and the silver task force we will continue to be at the forefront of the process for annex listings for both silver and copper.

So don’t worry, everything is in hand and you are covered. Copper is back on the market and it looks set to be this way indefinitely.

We would like to thank you for your continued support through this difficult process.

The ProEconomy team.
