Question from Steve

Does anyone know what the least toxic fire extinguishers are? I know the foam and chemical residue they leave behind are very toxic and require a severe clean up job.  Are there newer safer materials being used.  Many fire fighting foams use highly toxic PFAS chemicals.

Also, do extinguishers emit trace amounts of chemicals when stored in homes?

If anyone can recommend a brand available in the U.S. that would be appreciated.


Lisa’s Answer

I am not aware of any fire extinguishers that do not use PFAS chemicals.  Readers, any suggestions?

I would not expect the chemicals to release from the extinguisher when not in use but I am not aware of any testing that confirms this.
