Porong Posted October 15, 2020 Report Posted October 15, 2020 Hi I am wondering if there is a way to freeze protect a back pack fire extinguisher 19 L with foam would be to drop a plastic soda bottle with diluted rv anti freeze ( propylene glycol ) in it any ideas? thank you I do not need this as a code requiried unit ideas please thank you Quote
AnthonyB Posted October 16, 2020 Report Posted October 16, 2020 No, only use the manufacturer's approved anti freeze agent in the correct amount otherwise you invalidate all warranties and more importantly could degrade the foam removing it's class B capability. Quote
