NFPA 13 is the standard for design and installation of automatic fire sprinkler systems. It governs placement, spacing, hazard classification, and water supply requirements.
Storage must be kept at least 18 inches below sprinkler deflectors to avoid blocking water spray. This ensures proper coverage during activation.
Sprinklers must also be replaced if damaged, corroded, painted, or previously activated.
Not always. Local codes may require exposed sprinkler piping to be painted red, but hidden piping often has no color requirement. Sprinkler heads themselves should never be painted.
