The Foundation has previously completed work on the impact of obstructions on ESFR sprinklers in storage occupancies. Similar research is needed related to spray sprinklers and obstructions. There is a need to assess the current rules related to spray sprinklers, including the beam rule, four-foot rule, group obstructions, etc., along with the technical justifications and available research to determine the knowledge gaps. This effort focuses on that review. It is expected that future efforts would focus on filling in the knowledge gaps and developing the technical basis for any new requirements or guidance in NFPA 13, Standard for the Installation of Sprinkler Systems.
The Foundation has issued an RFP for a project contractor for this project on “Impact of Obstructions on Spray Sprinklers.” You can find the RFP on the Foundation website. The deadline for proposals is March 29, 2019 at 5 pm EST.
