(OP)
we have MCC system equiped with co2 supresion system,we like to remove this system
is that normal  practice?

RE: co2

Is the motor control center (MCC) in a building protected by an automatic sprinkler system?

Is the MCC located in a building in the US?

If not - not a problem.

RE: co2

I think it's unusual to have CO2 in a building that is normally occupied due to the life safety risk if the system ever discharged with someone in it.  

If an organisation has a CO2 system they may consider taking it out for safety reasons.  

RE: co2


Are there liquid filled transformers?  Probably so.

There is not enough information to be able to help you.   Somebody thought it was necessary to the system in.  Find out why and then mitigate that risk in a different way, if possible.  Only then remove the CO2.

to *put* the system in.

the MCC is inside a building

RE: co2


Again, you have not spent the time to enter the readily available and pertinent information, so that people here can give you free technical advice..

If you can't even do that much, and further more haven't bothered to look up any codes and standards on your own, then I don't see how you expect to make an informed decision.   Might as well flip a coin to get your answer.  Good luck with your project.

RE: co2

Your question is not clear.  Either you are asking whether it is normal practice to remove systems, or you are asking whether it is normal practice to have CO2 systems within a MCC "system".

Normal practice is to maintain fire suppression systems, not remove them.

If you are asking whether it is normal practice to have a CO2 system within a MCC, more informaton is required.

I thought of the following questions right off, there are probably a lot more:

1. Why do you want to remove the suppression system?
2. Has something changed to make the CO2 system unsafe? (Is the space now occupied, or normally unoccupied, as opposed to unoccupied.)
3. Is it spot or total flood system? Is it a high pressure CO2 or low pressure CO2 system?
4. Is the system protecting the area within an enclosure for just the equipment or is it within a larger room that houses the equipment?
5. What kind of equipment is being protected?
6. How old is this system?

If it is an older installation there may be a better way to protect the area and resolve other concerns.  

Normal practice may have changed, but I doubt that going from something to nothing is a good idea.
