Fire Sprinkler Heads, Design, and Failure

  • R. I. Garber
Feature

Abstract

Sprinkler heads are a mature product that can fail to function via a variety of different mechanisms. Mechanical damage and corrosion can occur year round. Additionally, there can be seasonal failures due to creep of fusible alloys in summer. Serious problems also have occurred due to sticking of sliding O-ring seals. These problems have lead to product recalls, and subsequent revisions in design standards.
