Risk Assessment Specification...
The following areas would be reviewed:
- Assessment of management records
- Water stagnation
- System design, installation and materials
- Operational and maintenance regime
- Storage conditions of cold water
- Storage conditions of hot water
- System usage
- Temperature measurement
The purpose of a Risk Assessment is to evaluate your plant, equipment, operational and management of the building systems and their risk of bacteriological proliferation.
Your risk assessment would include all hot and cold water services, which will incorporate an assessment of the design, usage and condition. All information would be recorded on pro-forma forms and collated within a single comprehensive document.
Temperature measurements would be completed, checked and evaluated and the following standards should be met:
- Hot water storage at above 60°C
- Hot water storage at discharge points above 50°C within one minute of running
- Cold water storage at below 20°C
- Cold water storage at discharge points below 20°C within two minutes of running
- Colour schematic drawing produced showing pipe links between plant assets and building water distribution. Colour coded: Blue = Mains Water, Green = Tanks Water and Red = DHWS
Where hot water is discharged at more than 50°C and there is a risk of scalding the risk assessment should identify the need for thermostatic mixing valves or other forms of temperature control.
Areas requiring remedial work will be covered in your report.
