  • FIRE SEPARATION REQUIREMENTS IN THE IBC - John P. Stoppi

    Apr 21, 2019Within Table 509, there is a list of incidental building uses that require separation and/or sprinkler systems. For example, an equipment room with a gas furnace input rating of 500,000 btuh would require a 1 hour fire barrier separation. Every building design should check Table 509 to see if any incidental separation is required.
