Automatic Sprinklers Obstructions

When a sprinkler head activates, it's critical that the water reaches the burning material quickly. An obstruction not only impedes rapid water delivery — allowing a fire to grow — but also causes splashing and cooling that can prevent or delay additional sprinkler heads from opening.

That's why a well-designed sprinkler system minimizes obstructions, such as:

  • building structures
  • bar joists
  • bridge strapping
  • electrical conduits
  • lighting fixtures
  • ventilation ductwork
  • cable trays
