AS 2118/4118

This series groups together the current parts to Australian Standard, AS 2118 Automatic fire sprinkler systems, and; AS 4118 Fire sprinkler systems, available in the BIG library.

The AS 2118 and AS 4118 series are Australian standards that provide guidelines for the design, installation, and maintenance of fire sprinkler systems. 

- AS 2118 covers the general requirements for automatic fire sprinkler systems in buildings. It includes guidelines for system design, installation, and maintenance to ensure that sprinkler systems effectively control or extinguish fires and protect property and lives.

- AS 4118 focuses on specific requirements for fire sprinkler systems used in high-risk and specialised applications, such as hazardous areas or large-scale industrial facilities. It provides detailed criteria for the design and performance of these systems to address unique fire protection challenges.

Together, these standards ensure that fire sprinkler systems are appropriately designed and maintained to provide reliable fire protection in various types of buildings and environments, helping to enhance safety and minimise damage in the event of a fire.
