You'll never get your insurance company to sign off on this. The US
Navy loses people to CO2 fire suppression systems from time to time;
acceptable risk on a warship and acceptable risk in a data center are
not even on the same page. This includes dumps that are unintentional
- having enough CO2 around to do meaningful fire suppression in a
moderate size datacenter has its own hazards associated with it.

Being in the same room as a halon or fm200 dump is bad enough. I
don't think I'd be willing to work at (or make my employees work at) a
datacenter that had CO2 fire suppression installed, no matter how
strenuous the assurances were that there were interlocks in place.
