You keep mentioning this government stuff, so...wouldn't that imply that (if you are in the US) you are supposed to be NIST 800-53 compliant? At a certain point, this stuff can become "gross negligence" as in "people have been told and just don't GAF", and certain legal remedies will be applied on you and them by external agencies outside your control. There are very specific controls around environmental systems that affect the availability of data and systems. AT-3(1) is one off the top of my head..."Environmental controls include, for example, fire suppression and detection devices/systems, sprinkler systems, handheld fire extinguishers, fixed fire hoses, smoke detectors, temperature/humidity, HVAC, and power within the facility. Organizations identify personnel with specific roles and responsibilities associated with environmental controls requiring specialized training." PE-14 is another that requires defining specific environmental settings, procedures to implement, AND ways to ensure compliance.

Seriously, you are one more bad move away from a disaster...these situations are why whistleblower protections exist. Someone at your org is RESPONSIBLE FOR ENFORCING this stuff, like legally responsible on a dotted line somewhere. You need to let your boss know that this is a "big deal", like potentially "getting called to testify in front of Congress" level if some national security related data gets fubared because your Facilities people lack the REQUIRED training to do their job concerning crititical IT equipment. You should have a registered FSO (facilities security officer) someplace, you need to contact them ASAP before you loose hundreds of thousands of dollars (tax-payer funded most likely) of equipment due to ineptness.
