Give Fire Extinguishers a pressurized gas reservoir as well as their normal reagent reservoir. Give it 1 litre of gas capacity that is capped at 500 kPa. Spraying the extinguisher depletes both the gas and reagents at equal amounts per tile sprayed, so that a fully-filled extinguisher would fully empty both the reagent and gas reservoirs at the same time during normal usage. All fire extinguishers would come pre-filled with Nitrogen and firefighting foam, and firefighting foam reservoirs would have an integrated gas canister that recharges foam and gas at the same time. (Some basic "hacking" of the machine would let you dispense either gas or foam individually.)

Allow fire extinguishers to be attached to gas tanks and placed into O2 Vendors/repressurizers/etc. in order to recharge them with any gas you want. Using the extinguisher would add a proportional amount of gas from the cartridge into the sprayed environment. Spraying an extinguisher with no reagent and only gas would still let you spray gas and propel yourself in space, but wouldn't apply any chems. Spraying an extinguisher with no gas would dribble the reagent inside the extinguisher at your feet in a sad puddle.

This would allow for more creative uses of fire extinguishers depending on the gasses added (and the temperature of the gas added), while making it slightly harder to refill extinguishers with random reagents on the fly due to the extra gas-filling step. Using fire extinguishers for regular fire fighting is unaffected, as the firefighting foam dispensers deal with the gas filling for you. It also reflects how similar in-game items (i.e. the flamethrower, which requires a pressurized gas tank) and IRL fire extinguishers work.

Also, let me spray cryostylane from a fire extinguisher, you cowards. Why is that even on the fire extinguisher chem blacklist anyways? Don't tell me that the justification is that the nozzle is getting frozen over by ice.
