Spray sprinklers are the oldest type of sprinkler in regular use today and still the most versatile. NFPA 13 contains general obstruction requirements for all sprinklers as well as specific requirements for each specific type. Fixtures, structural members, and more, may or may not be considered obstructions to sprinkler discharge. Different obstruction rules vary with the characteristics of the obstruction. This seminar will explore the rules governing clearance to both standard spray sprinklers and extended coverage spray sprinklers and demonstrate the impact of the rules on sprinkler spacing.
