A building with roof-mounted, gas-fired equipment shall have a permanent inside means of access when the height of the building is more than what height?

In the context of building safety and maintenance, regulations often stipulate that when a building has gas-fired equipment installed on the roof, there must be a means of access for maintenance, inspection, and emergency response. The specific height threshold of 15 feet is set as it represents a point where accessing the equipment for safe and effective service becomes increasingly hazardous without proper access provisions.

At heights above 15 feet, standard ladders or other access methods may not provide adequate safety, making it essential to include a permanent means of access, such as an internal stairway, ladder, or crawl space. These requirements help ensure that technicians can safely reach the equipment and carry out necessary services without undue risk. Hence, 15 feet is recognized as a critical height in promoting safety and operational efficiency when working with gas-fired systems on rooftops.
