When is a permanent inside means of access required for roof-mounted, gas-fired equipment on a building?

A permanent inside means of access is required for roof-mounted, gas-fired equipment when the building exceeds 15 feet in height. This requirement is based on ensuring safe accessibility for maintenance and servicing of the equipment. As buildings increase in height, the complexity and risk associated with accessing rooftop installations also increase, which is why specific height thresholds are established by safety codes.

At heights greater than 15 feet, there is a heightened necessity for safe and reliable access routes to prevent accidents and facilitate effective maintenance. Such access may include ladders, stairways, or other designated means to ensure that service personnel can reach the equipment safely without the risk of falls or other hazards inherent to working at elevation. This regulation reflects a commitment to safety and adherence to best practices in the maintenance of gas-fired equipment.
