Perform Monthly Legionella Audit using eAuditor
A Monthly Legionella Audit is a routine inspection conducted to assess the risk of Legionella bacteria growth in water systems. This audit helps ensure compliance with health and safety regulations, minimizes the risk of Legionnaires’ disease, and verifies that control measures are effectively preventing bacterial contamination.
Conducting a Monthly Legionella Audit using eAuditor ensures a systematic evaluation of water systems to minimize the risk of Legionella bacteria growth. eAuditor’s digital checklists, real-time data tracking, automated reporting, and compliance monitoring streamline the audit process, ensuring facilities adhere to health and safety regulations while preventing Legionnaires’ disease outbreaks.
Preparing for the Monthly Legionella Audit
Proper preparation ensures a comprehensive and efficient audit by gathering the necessary tools and configuring eAuditor for detailed data collection.
Key Preparations:
- Gather essential tools such as a calibrated thermometer, dip slides, water sampling bottles, and disinfectants.
- Review previous Legionella risk assessments and water system maintenance logs.
- Set up eAuditor with a customized Legionella audit checklist, covering temperature monitoring, water stagnation, biofilm risks, and disinfection practices.
- Inform maintenance teams and facility managers about the scheduled audit for proper coordination.
Conducting the Monthly Legionella Audit Using eAuditor
Using eAuditor, inspectors can systematically assess water systems, record real-time observations, and generate compliance reports for corrective actions.
Water Temperature Monitoring
- Measure hot water temperatures at taps, tanks, and outlets to ensure they reach at least 50°C (122°F).
- Verify that cold water temperatures remain below 20°C (68°F) to inhibit Legionella growth.
- Record all temperature readings in eAuditor and flag any deviations for corrective action.
Stagnation and Water Flow Assessment
- Inspect unused or low-flow outlets, including taps, showers, and infrequently used pipelines.
- Ensure routine flushing of infrequently used water sources to prevent water stagnation.
- Log any dead legs or redundant pipework in eAuditor for potential removal.
Disinfection and Water Treatment Verification
- Check chlorination levels, biocide treatments, and UV disinfection systems to confirm proper dosing.
- Inspect storage tanks, cooling towers, and water heaters for sediment buildup or scale formation.
- Verify that disinfection procedures align with regulatory guidelines and document findings in eAuditor.
Sampling and Legionella Testing
- Collect water samples from high-risk locations for Legionella bacteria testing.
- Use dip slides or laboratory analysis to detect microbial contamination.
- Attach test results in eAuditor and escalate any positive findings for immediate remediation.
System Compliance and Documentation Review
- Ensure water management plans are up to date and comply with health and safety regulations.
- Confirm that staff responsible for Legionella control receive proper training.
- Check that remedial actions from previous audits have been addressed and closed.
- Use eAuditor’s automated reporting feature to compile findings and share reports with stakeholders.
Conclusion
A Monthly Legionella Audit using eAuditor helps facilities monitor water quality, prevent bacterial growth, and maintain compliance with health regulations. With real-time tracking, digital documentation, and automated corrective action assignments, eAuditor streamlines the audit process, ensuring safe and Legionella-free water systems in buildings and facilities.
