What does this form include?
This form contains 19 sections:
Date of original risk assessment or previous review: Date
Define the scope of the risk assessment being reviewed. I.E. which buildings and water systems
Is the name of the nominated responsible person up to date
- Is the name of the nominated responsible person up to date
- Is the name of the nominated deputy responsible person up to date
- Has the occupancy level of the building(s) changed since the assessment was completed
- Has the building had any change of use since the assessment was completed
- Has the susceptibility level of the building occupants changed
- Has there been any local construction of water systems, outside the building(s), that may affect the risk
- Is there any evidence of site staff being trained in Legionella awareness and their responsibilities within the control scheme
- Is there a written procedure to define the action to be taken if Legionella bacteria are detected in samples taken from site
- Is there a written procedure to define the action to be taken if a case of Legionnaire’s disease is suspected from water systems on the site
- Is there a written procedure regarding when and how to alternate hot or cold water pumps
- Are the responsibilities for carrying out the tasks within the control scheme clearly defined
By checking the available records, can it be shown that all recommendations of the risk assessment have been implemented
- By checking the available records, can it be shown that all recommendations of the risk assessment have been implemented
- Are there schematic diagrams for every water system
- Are the schematic drawings accurate with regard to the locations that they supply
- Do the schematic drawings show enough detail so that they are not ambiguous
- Is the outlet asset register accurate? I.e. are all of the outlet types and number defined in each location where water is used
- Is the “fixed asset” register accurate? I.e. are all of the cold-water storage tanks and hot water vessels recorded
- Is a supplementary biocide being dosed into any of the systems and has this been installed since the previous risk assessment
- Complete inspection sheets for all cold-water tanks and hot water vessels and make recommendations for remedial action as required
Is there a secure, close fitting lid fitted
- Is there a secure, close fitting lid fitted
- Is there a lid vent (tank breather) fitted and is it in good condition
- Is there an overflow screen fitted and is it in good condition
- Is the tank well insulated from heat gain
- Is the tank corroded
- Is there any evidence of scale deposition
Describe the level of sediment on the base of the tank. (Percentage covered)
Does the level control valve shut off before the overflow level is reached
- Does the level control valve shut off before the overflow level is reached
- Does the inlet supply valve shut off the supply
- Does the outlet valve shut off the outlet
Record the stored water temperature as far away as possible from the inlet valve.
Record the inlet temperature at the mains inlet.
Was an internal inspection of the vessel undertaken
- Was an internal inspection of the vessel undertaken
- Were the internal surfaces of the vessel covered in scale deposits
- Were there any signs of internal corrosion
- Is the vessel well insulated to prevent heat loss
- Does the vessel drain valve operate safely
- Was the vessel drain flushed until clear water was achieved
- Is there a flow/storage temperature gauge fitted
What is the stored water temperature
Is there a return line temperature gauge fitted
- Is there a return line temperature gauge fitted
What is the return water temperature
Is the return pump operating
- Is the return pump operating
Are the temperature records for all cold water systems complete
- Are the temperature records for all cold water systems complete
- Have all non-conformances in cold-water temperature been investigated and addressed
- Are the temperature records for all hot water systems complete
- Have all non-conformances in hot water temperature been investigated and addressed
- Are there full records of flushing for any identified “low use” outlets
- Has the risk assessment been reviewed and records produced at the agreed frequency
- Are there records to demonstrate that showers have been inspected and disinfected at least quarterly
- Are there records of duty/standby pumps being alternated on DHWS return
- Are there suitable records of any fitted biocide dosing system
- Are there records of cold-water tank and hot water vessel inspection
