Final answer:
Sprinkler head placement follows specific standards outlined by the National Fire Protection Association (NFPA) in their document NFPA 13. The standards include maximum spacing between sprinkler heads and minimum clearance from obstructions.
Step-by-step explanation:
Sprinkler head placement follows specific standards to ensure effective irrigation coverage. The standards are determined by the National Fire Protection Association (NFPA) and are outlined in their document called NFPA 13: Standard for the Installation of Sprinkler Systems.
One of the standards for sprinkler head placement is the maximum allowed spacing between sprinkler heads. According to NFPA 13, sprinkler heads should be placed so that the maximum distance between any two heads does not exceed the coverage radius of each individual head. This ensures that the entire area is adequately covered.
Another standard is the minimum clearance between sprinkler heads and any obstructions. NFPA 13 specifies that sprinkler heads should have a minimum clearance of 18 inches between the deflector and any obstruction, such as beams or walls. This allows the sprinkler heads to function efficiently without obstruction.
