New Legionella control software packages are now available from specialist suppliers for those looking for a pragmatic approach for legionella control. Making use of the latest technology, new software packages can greatly assist in the management of legionella control strategies, which are described in the Approved Code of Practice and Guidance: the control of legionella bacteria in water systems (L8). Specific software is available for:

• Identifying the risks (risk assessment);
• Monitoring precautions (daily, weekly, monthly, annually);
• Maintaining records (including details of those responsible).

Legionella-software is increasingly becoming an integrated and important part of every day legionella control strategies; it is also a useful tool for the early warning of situations which otherwise could result in potential hazards. It is important to remember that Legionella-software packages should always be backed up with full technical support and training from the supplier.

Risk Assessment

The software package should be comprehensive, and provide the following:

• Client contact information
• asset registers and equipment surveys
• control programs
• an executive summary, detailing a site specific control scheme and describing the frequency and items of control measures necessary to avoid potential risks.

Software should be easy to operate and flexible in meeting the client’s requirements, the following should be included:

• A comprehensive list of site survey questions, ensuring that all areas of potential risk are covered
• Handheld computer options, which can significantly reduce time by allowing on site data input; simple synchronisation at the office allows a report to be formulated on the main computer
• A PDA (Pocket PC) with internet access makes this system more flexible by allowing an assessor to send the information to a computer via the internet, especially useful for multi-site operations
• The program’s memory should allow for data adjustments to be made with site specific answers; client information includes names of those responsible which are easily recalled to reduce future inputting time
• Risk and Priority ratings options, which can easily be adjusted to meet the client’s needs. Priority areas should be automatically highlighted (flagged) when potential problems arise
• The ability to print out all information in a clear and concise format.

Monitoring

A Logbook feature should also be supplied, which provides an in-depth schedule in the form of a calendar. A simple process should extract relevant information from the Risk Assessment software and transfer it to the Logbook, which allows the user to:

• View daily, weekly, monthly, quarterly and annually scheduled tasks
• Identify any non-conformities and their status
• Report test results
• Identify due or overdue tests through eye catching colour codes
• As with Risk Assessment programs, relevant data can easily be transferred onto a PDA, so an onsite technician can record information, which can be immediately be sent back to an office computer.
• Software is an effective tool for legionella control management, not only in terms of safety but also for cost reduction as considerable time and effort can be saved.

Legionella-software should always be relatively easy to use, making every day tasks easy to identify and monitor. Popular software makes best use of the easy ‘windows’ similar format, and initial training provided by an easy screen-by-screen explanation has proven very successful.

Legionella-software is becoming increasing popular for both the end user and service providers alike; proving to be a highly effective tool for improving performance by identifying risks and managing responsibilities effectively, any action or non-action taken is recorded in the inbuilt audit system.
