Introduction and Assessment of Risk
Introduction
-
This risk assessment has been carried out to ascertain the possible risk of contracting Legionellosis, including Legionnaire’s disease, from water systems and to identify remedial works required and produce a scheme for the prevention or control of the risks. This report relates to the risk assessment and water hygiene survey completed for this facility.
Assessment of Risk
-
To assess the risk of Legionella Bacteria associated with water usage at this site, each of the water services are surveyed and allocated scores. The scoring system enables necessary remedial actions to be easily prioritised. This method of assessment is designed to identify features, which contribute or combine to
form an increased risk and to aid in the design of a scheme to control the risk from Legionella bacteria.
A Group Susceptibility Rating relating will be applied for any type of population group that would be at risk if exposed to Legionella bacteria. This is based on the general age, gender, and health conditions of the at risk.
In accordance with ACOP L8 (2013) – This risk assessment must be reviewed regularly and/or whenever there is reason to believe that the original assessment may no longer be valid.
We cannot guarantee that all pipe work passing underground or through floors, walls and ceilings has been traced, and it is possible that certain system dead-ends or dead legs may not have been identified. As a result, the schematic diagram(s) contained within this report only detail the visible or assumed pipe work.

Risk Assessment
- Water Heaters
-
Instantaneous or Point of Use water heaters present little risk of harbouring Legionella bacteria due to the nature of the plant. They are not required to reach any temperature criteria but should be in good condition and inspected frequently.
Low Volume (<25 Litres) water heaters present a slight risk of Legionella and should be monitored in accordance with ACOP L8 and HSG 274, the condition and operating temperature of these are listed below.
Where water heaters store over 25L of water they present a larger risk of Legionella and as such subject to a higher degree of inspection. -

-
Are there arrangements in place to flush them through on at least a weekly basis?
Dead Legs and Redundant Pipework
-
Sections of pipework which are redundant or owing to the system design and have little/no through the flow of water (knows as 'dead legs") can allow water to stagnate in the system.
