AEC enjoys long working relationships with several NHS Hospital Trusts providing legionella risk assessments and consultancy services.
During a routine inspection AEC’s consultant identified a water hygiene risk at the hospital where it was noted that the cold water tanks supplying the calorifiers were installed in such a way as to subject them to heat, allowing stored water to regularly exceed the recommended maximum temperature of 20°C, increasing the risk of Legionella proliferation.
AEC provided a feasibility assessment and a new specification in line with the current water regulations and British Standard BS6700 (now BS8558).
This was approved by the Trust, and AEC led the project to provide independent technical assistance to the installation contractors. The whole process was managed with minimal disruption to hospital services.
Following recommendations regarding suitable training, AEC provided two levels of bespoke training - for site managers and operatives.
Since then, the responsible person and deputy have undertaken the BOHS P901 course ‘Legionella – Management and Control of Building Hot and Cold Water Services’ provided by AEC.
AEC is still the retained water hygiene and legionella consultants for the Trust, and following these works the problem of excessive temperatures in the tanks had been resolved, reducing the risk of Legionella proliferation.
We continue to have a good working relationship with the Trust, and provide Legionella risk assessments and reviews, audits of site based monitoring and record keeping.
