125 Rated Info Computer media is the most fragile method of storing vital information assets. Computer media is destroyed as the temperature rises above 120°F and is lost at 125°F (52°C). Many vaults on the market can provide protection for paper documents (Class 350 Fire Rating) and some for microfilm (Class 150 Fire Rating), but anyone representing a Class 150 Vault or Server Room as being protective of computer equipment and the more valuable information contained on computer tapes, hard drives, disks and servers is not presenting the client with a real solution in the event of a catastrophic fire. The goal of your vault should be to maintain an interior temperature below 125°F and less than 80% relative humidity for the duration of your desired time period of protection. Representing a Class 150 Vault as offering a 90-minute solution deceives the client into believing the media is safe for 90 minutes when the recorded information is destroyed at 45-60 minutes. Fire brigades simply cannot guarantee to have a fire in an office building or data center extinguished in as little as 60 minutes from the arrival on site. The fire fighting setup and the search and rescue that must occur in the site prior to actually activating the hose stream can use up most of this time. Common sense tells the owner of the data center or office that a prudent design is one that allows proper time for fighting the fire, extinguishing and then the lengthy cool down period. The entire vault must be stable for this five-hour period or everything is at risk.
