On the 8th January 2001 the Health & Safety Executive published L8 “Control of Legionella Bacteria in Water Systems” Approved Code of Practice & Guidance.
This relates to all commercial, industrial and municipal properties which have water systems and within L8 there is a requirement to carry out assessments of the risk of proliferation of Legionella and other bacteria within water systems.
We have been providing assessments of a range of systems for over 15 years, fundamentally the objectives are:
1 To establish the current position regarding water service condition.
2 To establish a record of plant data.
3 To identify areas where modifications or adjustments may be required from a water quality and/or safety point of view.
4 To establish a programme for compliance with L8 the Control of Legionellosis including Legionnaires Disease.
Our Risk Assessments frequently cover the following:
i) Incoming Water
ii) Supply Water Tanks
iii) Hot and Cold Water Systems
iv) Calorifiers & Heat Exchangers
v) Showers & Spray Forming Outlets
vi) Cooling Systems
vii) Water softeners and filters
viii) Humidifiers & air conditioning units
ix) Miscellaneous Plant
x) Management Records, Schematics & Control Procedures
We utilise guidance from L8 and several relevant documents relating to the control of Legionella, in our assessment & subsequent recommendations.
Schematics are frequently not available or not suitable, we can provide a schematics drawing service ideally undertaken during the assessment or available as a stand alone service.
We frequently find that systems which appear to be satisfactory and in accordance with L8 can still have hygiene problems. It is for this reason that we strongly recommend sampling to compliment the physical data obtained during the assessment.
To obtain full benefit from a Risk Assessment it is important that our staff are assisted to access all parts of the system during our visit and that your site records are available.
Responsibility for compliance following the Risk Assessment remains with the Responsible Person who needs to review it, implement recommendation and undertake routine preventative procedures. Risk Assessments are required to be reviewed normally after two years but they should also be updated if there are significant system or other changes.
