The case of an apartment complex that recently underwent a crucial inspection illustrates the importance of adhering to the regular inspections and maintenance schedules of fire water tanks. During an Annual AS1851-compliance inspection, a series of significant issues were discovered using an ROV Drone in a long-neglected tank: a failed lining, exposed concrete interior, severe corrosion of internal fittings, a non-functional inlet, and a water level significantly below capacity.
Understanding Inspection Schedules for Fire Water Tanks
AS1851 prescribes specific intervals for fire water tank maintenance: monthly, 6-monthly, annual, and every ten years. The incident at the apartment complex highlights the critical nature of following these guidelines.
Flexibility in Scheduling Inspections According to AS1851
While regular inspections are mandated at set intervals, AS1851 also provides allowances for adjusting these times to better suit operational demands without compromising safety or compliance:
- Monthly Inspections can be adjusted by up to 5 working days.
- 6-Monthly Inspections may be postponed or advanced by one month.
- Annual Inspections have a flexibility of up to 2 months.
- 10-Yearly Inspections can be shifted by as much as 6 months.
This flexibility is essential for managing maintenance schedules more effectively, ensuring inspections are thorough and timely while accommodating the unique needs of each facility.
Monthly and 6-Monthly Inspections: Essential Early Detection
Monthly and 6-monthly inspections are vital for early detection of potential issues. At the apartment complex, regular performance of these inspections could have identified the reduced water level and the malfunctioning inlet earlier. Monthly checks focus on visible concerns, while 6-monthly inspections can reveal issues that develop over time, such as the early stages of water level fluctuations and inlet problems.
Annual Inspections: The Thorough Examination
The annual inspection is designed for a comprehensive assessment of the tank’s condition. In the apartment complex, the ROV drone inspection was key in uncovering extensive problems like the failed lining and corroded fittings. These annual inspections are critical for evaluating both the internal and external state of the tank, ensuring its operational readiness.
10-Yearly Inspections: The Deep Dive with Cleaning
Every ten years, an in-depth inspection coupled with cleaning and sediment removal is essential. This cleaning process is crucial for maintaining the tank’s structural integrity and water quality. At the apartment complex, the neglect had led to significant sediment accumulation, exacerbating the tank’s problems. The 10-year inspection would have not only identified structural and internal issues but also facilitated the necessary cleaning to prevent further degradation.
ROV Drone Inspections: Precision Meets Innovation
The ROV Drone Inspection at the apartment complex played a critical role in revealing the extent of the tank’s neglect. This method allows for a detailed assessment, crucial for identifying complex issues in overlooked tanks.
