Legionella Control & Prevention measures are just as important as the risk assessment and testing.  The HSE's ACOP L8 gives guidance on effective control and prevention measures.  Failure to establish, maintain and record the measures undertaken can result in substantial fines, prosecution and even imprisonment.

The control and prevention measures that you need to put in place should be detailed in any risk assssment.  The required measures will vary from site to site and need to be carried out by someone who is competent.

 

Whilst measures may vary from site to site there are common measures that should be in place for every site such as flushing infrequently used outlets, regular temperature monitoring, cleaning and descale of outlets as well as regular servicing of water heaters, cooling towers and air conditioning systems.

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.

Flushing

 

Legionella bacteria needs the correct environment to grow.  The HSE has identified that outlets that have not been used within a week present an increased risk of Legionella bacterial growth.  Infrequently used outlets need to be either removed if no longer needed or flushed on a weekly basis to minimise the risk of Legionella.

Temperature Monitoring

 

Temperature monitoring is far more involved than 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 "sentinel" 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.

Showers & Spray Outlets

 

In any hot and cold water system there are outlets which will encourage 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 Valves

 

Thermostatic Mixing Valves or TMV's artificially adjust water temperatures to minimise the risk of scalding.  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.

Cold Water Storage Tanks

 

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.
