Water curtain using automatic sprinklers to avoid providing opening protectives - there's a lot of confusion on this.
Exception stated under Section 705.8.2 of 2021 International Building Code (OBC) states that Opening protectives are not required where the building is equipped through an automatic sprinkler system in accordance with Section 903.1.1 and the exterior openings are protected by a water curtain using automatic sprinkler systems approved for that use.
Can we use this exception and provide a water curtain using automatic sprinklers to avoid fire rated doors in the loading dock of a building?
Is there anything else that I need to be concerned about while designing these sprinklers for the water curtain?
Need more clarity here before recommending an approach. Thanks in advance.
