Code Update for Antifreeze Systems

Written by Beth Faris | Jun 13, 2023 6:45:58 PM

At PSI, your business’s fire and life safety is our priority.  We take pride in protecting the safety of your people, property, and organization by ensuring that your systems meet NFPA codes and standards. 

We want to inform you of a major code change that may require a change to your antifreeze system, especially if it was installed prior to September 30, 2012.

Why the Code Has Changed

Antifreeze solutions installed prior to September 30, 2012 (and sometimes even after that date) were found to be potentially combustible, serving as fuel to a fire and in extreme cases resulting in flash fires or explosions upon deployment.

Current Code Requirements

The current code requires that all antifreeze systems must use non-combustible UL-listed solutions. Any antifreeze system found to have a combustible non-UL listed solution installed must be fully flushed and the antifreeze replaced with a non-combustible UL listed solution. All antifreeze systems must also display proper signage with details about the solution installed.

How PSI Can Help Keep Your System Code Compliant

At your next annual antifreeze inspection or upon request, we will verify that your system has proper signage and contains a non-combustible UL-listed solution.

If your system meets code, no further action is required. If your system does not meet code, our team will provide you a quote to:
  • Drain your system
  • Refill it with a non-combustible UL-listed solution
  • Attach required signage
