Legionella Risk Assessment
Legionella control, based on a Legionella risk assessment in Northfleet, is the key aspect of the ‘Responsible Persons’ duties regarding the supply of wholesome water and L8 compliance.
There are many elements to a comprehensive Legionellosis risk assessment in Northfleet but the following are essential to achieve L8 compliance: –
- Site Identification and Governance
- Executive Summary – Outlining management actions required
- Contact, Responsibilities and Escalation Procedures
- Remedial Actions – Needed to bring the site into compliance
- Ongoing Monitoring Scheme – Actions required to maintain hygiene and restrict bacterial growth
- Plant Identification and Assessment
- Equipment Register
- Schematic Diagram
Water Systems Dosing

There is plenty of legislation concerning environmental hazards from the Management of Health and Safety at Work 1999, through COSHH and RIDDOR. However, these can be vague as to exactly what specific actions should be taken. The one document that sums up the requirements, and is used as the basis for Legionella risk assessments in Northfleet, is ‘Legionnaires’ Disease: The control of legionella bacteria in water systems’ – Approved Code of Practice and Guidance L8 (Fourth edition 2013).
- Between 200 and 250 people die in Britain each year from Legionnaires’ disease although it is accepted that this is an under estimate as the symptoms are often mistaken for flu.
- Management measures are generally straightforward and involve repair to the infrastructure and temperature monitoring. In more difficult cases additional governance measures such as low level biocide dosing can be employed.
- Feedback and evaluation, usually through bacterial sampling, enables oversight of the effectiveness of the programme
