Legionella Problem

Legionella infections can thrive in large industrial and commercial water systems, where water is used for both food and drink production in industrial applications or for drinking water in buildings such as office blocks, residential tower blocks, hospitals and large buildings.

Legionella Bacteria ImageLegionella Bacteria (pictured) is more commonly known as Legionnaires' Disease which is potentially fatal form of pneumonia where everyone can be susceptible to its effects.
If you are an employer or a person in control of a building, under general health and safety law, you have to consider the risks from Legionella that may affect your staff or members of the public and take suitable precautions.
If you are a manufacturer or person in control of water systems in a manufacturing environment then you should also consider the risks from Legionella in your manufacturing processes and take suitable precautions.

Legionnaires' Disease Prevention

There is a prevention for any potential water infection from Legionella; it is called Chlorine Dioxide or Cl02 which is a chemical compound of Chlorine and Oxygen. In the correct dilution in water, Chlorine Dioxide acts as a disinfectant and can eliminate the risk from Legionella and other harmful water borne pathogens.

This method of disinfection is suitable for industrial uses where the treated water is to be used in food and drink production as well as for drinking water situations such as office blocks, residential tower blocks, hospitals and other large buildings.

I just wanted to make a formal comment on the works carried out last week. Ian and Steve were still on site with me at quarter to eight on Thursday night after a long and trying day. The weather was dreadful, having rained all day, we were all wet and tired, yet they were both happy to stay and get the works finished. This is the sort of work load I expect to have to put in myself as it is my company. However, to have both the lads offer the same level of commitment, even though the hotel was twenty minutes away and they could have left, is outstanding and deserves to be commented upon. As you are aware I have known Ian for more years than I care to remember and he has offered invaluable support since he joined you, so I was not surprised that he stayed, but Steve could have gone and left us to it if he wanted to. Instead of this he worked on, and got all four units serviced and back to full operation without a word of complaint. It was a pleasure working with them and how friendly they both were. I have obviously thanked them both for their efforts and just felt you should also know how pleased I am with the way it went. I look forward to doing more business with you.
