Legionella Control & Prevention measures are just as important as the Risk Assessment and Legionella Testing.  The Health & Safety Executives Approved Code of Practice for the Control of Legionella Bacteria (ACOP L8) gives guidance on effective control and prevention measures.  Failure to establish, maintain and record the control and prevention measures undertaken can result in substantial fines, prosecution and even imprisonment.

 

I Have A Risk Assessment, Is That Not Enough?  The Risk Assessment is designed to identify and record the potential risk of Legionella.  It is a legal requirement to have a risk assessment carried out.  It is also a legal requirement to carry out control and prevention measures.  Failure to carry out these measures may be interpreted as a health & safety breach and could result in fines with a starting point of £10,000, prosecution and a potential prison term.

 

Regular control and prevention measures are essential to ensure health & safety.  The measures recommended can be very simple or in depth depending on the outcome of the risk assessment.  Whoever carries out the recommended control and prevention work needs to be competent to do so.

Are We Competent?  As a Duty Holder or person in charge of premises it is your responsibility to ensure anyone who undertakes work in your property is competent to do so.  At Water Wise we have over a decades water industry related experience and are;

Our Prevention & Control Service, We can arrange to visit you on a regular basis, usually monthly, quarterly, six monthly or yearly and carry out a range of control & prevention measures.  Once control & prevention measures have been established based on the recommendations made in the Legionella Risk Assessment our engineers will put in place a schedule of work.

 

During prearranged appointments we will visit you and carry out the recommended control & prevention measures.  We will record the work carried out highlighting any issues which we will inform you about as soon as possible.  You can access the records in your "Customer Portal", click here for an example

 

The customer portal is designed to meet all the record keeping requirements for the work undertaken for you.  You will receive a link to your own password protected page so no one else can see your information.  If you have more than one site that is no problem, you can have a page for each location.

Temperature Monitoring

Temperature monitoring is far more involved then just putting a thermometer under a tap.  Outlets need to be tested in the correct sequence to ensure they meet the requirements of the ACOP L8.  To correctly carry out temperature monitoring you need to understand the requirements of the ACOP L8, how to identify a "sentinal" outlet, how to record and inspect a temperature profile, how to record stored water temperatures, how to measure temperatures into a TMV and much more.

Quarterly Cleaning & Disinfection

of Spray (Shower) Outlets

In any hot and cold water system there are outlets which will encourge the growth of legionella bacteria.  Shower heads and other spray outlets are some of the most common areas where bacteria may grow and because they spray water there is an increased risk in passing on the bacteria.  All spray outlets such as showers should be dismantled, cleaned and disinfected on at least a quarterly basis.

Thermostatic Mixing Valve (TMV) Servicing

Thermostatic Mixing Valves or TMV's artificially adjust water temperatures to minimise the risk of scaulding.  Unfortunately the temperature range that these valves adjust the water temperature too may promote bacterial growth.  To minimise the risk Thermostatic Mixing Valves should be serviced and cleaned on a regular basis.

Legionella Testing

Legionella Testing is not always required but where a need has been identified it should be carried out on a regular basis and by a UKAS accredited laboratory.

 

When samples test positive for Legionella bacteria then testing should be increased along with other control and prevention measures until the risk has fallen below acceptable levels.

Cold Water Storage Tank

Cleaning & Disinfection

Cold water storage tanks should be inspected at regular intervals to visually assess the risk of Legionella.  Legionella Testing of cold water storage tanks should also be carried out on a regular basis.

 

It is commonly believed that cold water storage tanks should be cleaned and disinfected every year, this is not the case.  If visual inspection and testing show there is no risk then there is no need for further action.
