First, I would say get with your management and let them know your concern and for the safety of families and properties you want to have an inspection of your fire extinguishers. Here is a little tidbit, now understand your state and city have their requirements, so use what I write here as an example only. Normally a minimum of a 5 pound ABC dry chemical or 3 gallon water extinguisher is mandatory).
I would get the maintenance man and get the old one collected up. Numerous was to do it, but I would say doing 10 or 20 at a time with temps put in place while the older ones are tested. Then the ones that have been tested. replace the collected ones with them and keep the process up until you have gone through all of your fire extinguishers.
Normally coordinating with the fire department ahead of time will save time with inspections and replacements. You could even have a resident rodeo in the evening where they bring their extinguishers get them checked, charged or replaced and make it a fun event where the fire department can even give some safety tips.
Now I am going above the fire extinguisher thing as if there was a problem there, I am sure there are others. Here is a sample from one location. Check with your city or country and I am sure they have the same kind of documents for you.
