If your warehouse stores A2L refrigerants, you could be out of compliance with fire code even if you think you’re playing by the rules.
That’s because while the 2024 model fire codes offer more flexibility for storing A2Ls, most jurisdictions haven’t adopted the new standards yet. If your local fire marshal is enforcing an older code (and many are) you’re still bound by outdated storage limits.
The new code updates how flammable gases are classified. Instead of lumping everything into one category, it now distinguishes between:
This shift allows for higher storage limits of A2Ls, but only in jurisdictions that have formally adopted the 2024 code. Until then, older limits still apply. And in many cases, that means you’re limited to just 300 pounds per control area.
If you’re over the limit under your current code, you’re at risk of:
This has nothing to do with the actual risk A2Ls pose. It’s simply a legal compliance issue you can address if you know what to do.
The 2024 fire code brings helpful changes, but they don’t apply until your local jurisdiction adopts them. Until then, your business is judged by the version that’s already on the books, whether it reflects current science or not.
Check your code. Know your limits. And take action before it becomes a problem.
