What factor determines the installation position for sprinkler heads in relation to obstructions?

• A. The distance from the nearest exit
• B. The type of fire hazard being protected
• C. The maximum allowable height of the building
• D. The presence of heating ducts

Answer: (B)

The installation position for sprinkler heads in relation to obstructions is primarily determined by the type of fire hazard being protected. Different fire hazards pose varying degrees of risk and require distinct protective measures. For example, areas with high hazard classifications, such as commercial kitchens or warehouses, may necessitate specific sprinkler spacing and placement to ensure effective coverage and prevent fire spread. When assessing the type of fire hazard, factors such as the nature of the materials present, the potential fire load, and the likelihood of ignition events come into play. This assessment informs how far away from obstructions, like beams, walls, or furniture, sprinkler heads need to be placed to ensure that their discharge patterns are effective at controlling or suppressing a fire. Although other factors like the presence of heating ducts can influence head placement (to avoid interference with discharge patterns), they are secondary to the fire hazard classification. Similarly, the distance from exits and the maximum building height relate more to egress and occupancy safety rather than to the specific need for sprinkler efficiency in regards to hazards.
