Summary

Understanding Fire Sprinklers

Fire sprinklers have a heat-sensitive element that breaks and releases water when exposed to high temperatures, similar to a TXV sensing bulb. Physical damage to the sprinkler, like being bumped, usually triggers the release of water, which can cause significant property damage. The podcast emphasizes the importance of being cautious around fire sprinklers, especially during hot work.

Best Practices to Prevent Accidents

Technicians are encouraged to use safety precautions when working near fire sprinklers. The episode suggests protecting the sprinklers during hot work using wet rags, avoiding blunt force injuries by being aware of surroundings, and ensuring proper training when using lifts. Signage and communication about the presence of fire sprinklers on job sites are crucial.

Emergency Preparedness

The podcast stresses the need for awareness and preparedness if a fire sprinkler activates. Knowing who can quickly access the fire shutoff and having a clear emergency contact plan can prevent extensive property damage. Proper training and proactive communication are highlighted as essential to safeguarding not only property but also the overall work environment.

Show notes

In this short podcast episode, Bryan talks about fire sprinklers and how to avoid setting them off on job sites.

Fire sprinklers have an element in the center that expands when exposed to heat (like a TXV sensing bulb) and breaks the glass. When the glass breaks, the fire sprinkler starts pouring out water. In some cases, fire sprinklers are linked to a larger fire suppression system in which several may go off at once, but most of the time, only a single fire sprinkler will go off if bumped or exposed to heat.

If you're using torches or doing any form of hot work in a closet or other location with a fire sprinkler, make sure to keep torches away from the heat-sensitive bulb or at least cover the sprinkler with a wet rag (and follow your company's guidelines). Blunt force is another possible issue, so we want to avoid hitting the sprinklers with lifts, ladders, or building materials like studs. Keep clearances in mind, and watch out for your colleagues.

You can get some specialty-built cages to protect the sprinklers, but awareness is one of the best ways to protect fire sprinklers. If possible, make sure signage is posted or that you alert other people in the area about the fire sprinklers.

If the fire sprinkler does go off, make sure you can quickly reach the person(s) who can access the fire shutoff or direct you to the fire shutoff. While fire sprinklers won't pose much of a personal safety hazard, property damage is a major concern. Training and awareness are the keys to preventing property damage due to fire sprinklers.
