What access must be provided to above-grade storeys for firefighting?

For above-grade storeys, the requirement for firefighting access is particularly important to ensure the safety of both occupants and firefighters. The building code stipulates that access must be provided to every storey that isn’t equipped with a sprinkler system, is not underground, or is over 25 meters in height. This is crucial because high-rise buildings or those without proper fire suppression systems pose a greater risk in the event of a fire.

When a building exceeds 25 meters, it becomes increasingly challenging for firefighters to access upper levels safely and efficiently. The lack of a sprinkler system further heightens the risk, as there are fewer controls on potential fire spread, which makes it essential for firefighters to have direct access to these storeys to conduct rescues and suppression efforts promptly.

This requirement ensures that firefighting strategies can be effectively implemented, safeguarding lives and property. The other options, such as providing access via a ladder only, limiting access solely through the main entrance, or indicating that no access is required, do not meet the safety provisions mandated by building codes for such scenarios.
