AS2293.2 is an Australian Standard for emergency lighting and exit signs in buildings. It sets out the requirements for the design, installation, and maintenance of emergency lighting systems, including the minimum illumination levels, battery backup times, and testing requirements for emergency lights and exit signs. The standard also outlines the requirements for the marking and location of exits, and the placement of emergency lights and exit signs to ensure they are easily visible and accessible to building occupants. The standard is maintained by Standards Australia, the country’s leading standards organization, and is regularly reviewed and updated to ensure it provides adequate protection for building occupants in the event of an emergency. Adherence to AS2293.2 is mandatory for all new buildings and major renovations in Australia, and it is widely adopted as a best practice standard for emergency lighting and exit signs in existing buildings.
