Understanding TAN 01: Simultaneous Water Supply for Fire Systems

Fire safety systems rely heavily on a consistent and effective water supply to function properly. TAN 01 – Simultaneous Water Supply provides guidance for water supply systems that serve both domestic and fire protection purposes simultaneously. In this post, we’ll explore the key principles of TAN 01 and what builders, property owners, and fire safety professionals need to know to ensure compliance and effective fire protection.

What is TAN 01: Simultaneous Water Supply?

TAN 01 (Technical Advice Note) outlines the standards for water supply systems that provide water for both domestic use and fire protection systems, such as fire sprinklers and hydrants. These dual-purpose systems must be designed to ensures the water supply for fire protection is not compromised.

Key Elements of TAN 01

1. Water Supply Prioritization

One of the most important aspects of TAN 01 is ensuring that the fire protection system always takes priority in terms of water supply. During an emergency, systems like fire sprinkler systems or fire hydrants must be able to draw the required amount of water, regardless of domestic water use at the time.

2. System Design Requirements

The TAN outlines specific requirements for how these water supply systems must be designed and installed to meet fire safety standards, such as:

      • Fire Sprinkler Systems: Proper sizing of water tanks and pumps to ensure consistent pressure and flow for fire protection systems.

      • Fire Hydrant Flow Tests: Periodic testing of fire hydrants to ensure they can deliver adequate water supply during emergencies.

    3. Compliance with Australian Standards

    TAN 01 emphasizes compliance with key Australian Standards related to water supply and fire protection, including:

        • AS 2419.1:2005Fire Hydrant Installations

        • AS 2118.1:2017Automatic Fire Sprinkler Systems

        • AS 1851:2012Routine Service of Fire Protection Systems and Equipment

      Meeting these standards ensures that the simultaneous water supply system is capable of serving both fire protection and domestic needs without any risk to safety.

      4. Pressure and Flow Considerations

      The TAN also provides guidance on calculating the necessary water pressure and flow rates to meet the requirements of both fire and domestic water demands. This includes ensuring that the system maintains a high enough pressure to supply water for firefighting operations even during peak domestic usage.

      Why TAN 01: Simultaneous Water Supply Matters

      Ensuring that water supply systems can support fire systems repairs and maintenance in Melbourne is vital for maintaining safety. TAN 01 helps builders and engineers design systems that can handle simultaneous demands without compromising the functionality of fire protection systems.

      Compliance and Inspections

      Compliance with TAN 01 ensures that building owners and managers meet local fire safety regulations and avoid potential issues during fire safety inspections. Regular fire hydrant flow tests and fire sprinkler system maintenance are necessary to ensure that these systems remain fully functional.

      Conclusion

      TAN 01 – Simultaneous Water Supply is a crucial document for anyone involved in the design, installation, and maintenance of water supply systems that serve both domestic and fire protection purposes. By ensuring compliance with the guidelines in TAN 01 and relevant Australian Standards, property owners and builders can ensure that fire safety systems will perform as needed during an emergency.
