We have been given the work to a new school, and there is a storm shelter built into it.
We want to run our pipe over head from the fire pump room, which is not storm-shelter protected, and penetrate through the storm shelter wall to protect this area. I just want to confirm if penetrating through the storm shelter wall is acceptable to do.
In the 2020 version of ICC-500, I understand it to read that penetrations shall not degrade the structural integrity and impact resistance of the storm shelter envelope. It also says that penetrations 2 ½ inches or larger in diameter should be considered openings and shall be protected in accordance with section 306.4 (impact protective systems and impact testing).
Then, reading into chapter 6, which is fire protection systems, it states: “These systems are not required to remain functional for the design storm event and minimum period of shelter occupancy (24 hours for hurricane shelters, 2 hours for tornado shelters) or to be protected from the wind load and impact requirements of Chapter 3 or flood-resistance requirements of Chapter 4.”
Is penetrating the shelter wall the best approach?
