Should garage doors be considered obstructed construction during design calculations?

When considering design calculations for fire sprinkler systems, garage doors should not be categorized as obstructed construction. This stance is based on the understanding of how garage doors function in relation to sprinkler systems. Unlike walls or other permanent structures that can fully impede the flow of water from the sprinkler system, garage doors can usually be opened, allowing for clear access to the area that needs to be protected. Additionally, when garage doors are in an open position, they do not impede the spray pattern of the sprinklers.

In design calculations, obstructed construction refers to permanent barriers that would hinder the effectiveness of sprinkler systems. Since garage doors do not represent a permanent obstruction and can be opened or are in alignment with intended use, they are treated differently when calculating water discharge and coverage areas. This distinction is important for ensuring adequate fire protection without overestimating the level of obstruction present in the design.

Other choices suggest conditional scenarios or specific building types, which could lead to misinterpretation of the best practices for encompassing the range of scenarios encountered in fire sprinkler system design. Overall, treating garage doors as un obstructed construction allows for more effective and practical fire protection design.
