Is a CO2 fire extinguisher safe to use to represent offensive magic or breath weapons in LARP?

In short: my friend, who is also a LARP organizer, has come up with the idea of representing breath weapons and some kinds of offensive weapons (those that are represented by a "cone template" in many games) via a CO2 fire extinguisher.
CO2 is basically just compressed air. However, I have experience of using it for cleaning purposes, and I know that it becomes extremely cold. So, I cannot be sure about its safety.
So, is one safe to use? If yes -- what safety measures do I need?

Does experience from SCA bouts count for such an answer?

CO2 is very much not "just compressed air".

CO2 extinguishers are not safe to use on people or in a room full of people.
Exit temperatures of the CO2 is -52°C in gaseous form and -78°C in snow form, enough to cause frostbite if it touches the skin. If that happens, it is recommended to remove most of it without rubbing it in and then seek medical advice.
It can also cause respiratory problems, especially among person who already have some troubles such as asthma, because the CO2 replaces the oxygen to put out the fire. While the risk is low when used outside, it is recommended to always open doors and windows wide if it's been used indoors to evacuate the CO2 and bring in fresh air.

DISCLAIMER: I am not a medical or safety professional.
They can be very dangerous
I would not recommend doing this. CO2 Fire extinguishers present 2 basic hazards.
Cold Burns
Do Not Touch the horn (the part that sprays CO2) when spraying a CO2 Fire extinguisher. The horn of a CO2 fire extinguisher becomes extremely cold during use, and can cause cold burns if skin comes into contact with it.
Additionally, while the CO2 rapidly warms once it is clear of the extinguisher, it is very hazardous at close range. You are spraying rapidly-evaporating dry ice out of this thing, which will cause cold-burns.
They displace oxygen.
This is the greater risk. The way a CO2 Fire Extinguisher works is that it pushes all of the oxygen in an area away, replacing it with CO2, thereby smothering the fire. This is obviously a problem, because humans need to breathe oxygen.
Based off this, here are two safety pointers if you do decide to point one of these at a person.
- Only use in a large, extremely well-ventilated area. Ideally, outdoors. In a confined space, a CO2 Fire extinguisher can lower the oxygen content of the space far enough to cause asphyxiation
- Do not sustain the spray for more than a few seconds at a time. Even in a well-ventilated area, the space that the extinguisher is spraying will quickly have too little oxygen to sustain a person. Sustained spraying can suffocate a person.
IMPORTANT: The CO2 continues traveling even after it is no longer visible as a cloud. Just because you can't see that you're spraying someone or something doesn't mean you aren't.
Conclusion
I would not, personally, recommend doing this.
But if you do, do so only in a very large and well ventilated space, stay several feet away from anyone while using it, and never spray for more than a few seconds at a time.
