Fire Damper Testing and Repair

Protecting your building is an ongoing effort, and it’s vital to verify every protection system’s efficacy and promptly repair malfunctioning mechanisms. Of all the components that make up a fire protection system, fire dampers are the most difficult to maintain. However, fire dampers are also critical safety features for hospitals or medical care facilities. These unseen mechanisms inside the air ducts and HVAC systems close when a room’s temperature reaches 165°F or higher — a sure sign of a fire. Fully functioning dampers prevent fires from spreading.

Whether you maintain a small practice or a large-scale hospital, the experts at Alliance Environmental can inspect and repair your fire dampers. Our technicians know the inner workings of fire dampeners and how to ensure their peak performance. Get in touch for services from one of the west coast’s top fire damper inspection companies.

Due to a recent leak in my home, I had the pleasure of working with Ryan from Alliance Environmental on removing asbestos. Ryan was very communicative with coordinating the timeline with me. The work area was nicely set up and isolated so I felt safe being in close proximity. Removal of the setup was very clean and no waste was left behind. I’m very happy with Alliance Environmental’s professionalism and work quality, I’d recommend them to anyone!

Fire Damper Testing

Testing your fire damper is important in preventing flames from spreading through your heating, ventilation and air conditioning (HVAC) ducts. According to the National Fire Protection Association (NFPA), dampers require inspection a year after installation and every four subsequent years. Inpatient hospital dampers require inspection every six years. A damper’s installation and performance must meet International Building and Fire Code (IBC) and National Fire Protection Agency (NFPA) standards.

Alliance Environmental’s inspection services will ensure you comply with relevant fire damper regulations by:

– Locating, marking and operating all fire dampers.
– Verifying the damper closes by removing and resetting the fusible link.
– Developing a report that documents damper location and life safety plans, inspection logs, failure explanations and repairs for noncompliant dampers.

Fire Damper Repair

Under NFPA 80 and NFPA 105, inoperable dampers require immediate repair, so call Alliance Environmental for assistance. Our crews can:

– Adjust damper linkage.
