Could your data centre benefit from advanced server room fire safety?

The vast majority of people never think about data centres. Yet, if they were all to disappear for even a single hour, modern life would collapse into chaos. They are the invisible, unglamorous backbone of our entire existence, as they process billions of bits of data every second of the day, keeping the internet ticking.

Because we expect them to work flat out without breaks, the sheer volume of electrical heat generated is staggering. It is a technological pressure cooker, with rows and rows of servers running white-hot, all packed in tightly next to miles of heavy cabling, high-voltage power units, and layers of plastic insulation. This could quickly become a delicate, high-tech tinderbox, where a single rogue spark could trigger a catastrophic electrical fire, scorching the digital lives that everyone takes for granted.

A standard building fire strategy is rarely enough to protect a data facility. Traditional fire safety systems are made to keep the walls standing long enough for people to make it to the emergency exits. That is obviously great for humans; less so for your priceless, hyper-sensitive server racks. Even a minor fire can trigger catastrophic hardware failure, causing huge financial losses, and erasing years of irreplaceable data. Implementing advanced server room fire safety measures is essential to shield delicate physical assets from thermal destruction, and to secure business continuity when a moment of downtime is a moment too long.

Understanding server room fire safety requirements

Compliance for both national and international standards needs to be the foundation of any risk-management strategy. Meeting your server room fire safety requirements will  involve understanding the unique environment of a server enclosure and how it compares to other locations. Traditional water sprinkler systems, for example, can cause as much damage to electronic circuitry as the flames themselves, making passive fire protection and specialised suppression systems the industry standard.

A key part of regulatory demands is that critical infrastructure compartments are able to withstand intense heat and structural stress. Specifically, these requirements dictate that server rooms must be isolated from the rest of the facility using tested fire barriers. This isolation serves to contain any internal electrical fire while simultaneously protecting the server racks from external building fires.

To achieve this level of compartmentalisation, you will need materials that are able to offer both integrity and insulation. Integrity is the term used to describe a barrier’s ability to prevent flames and hot gasses from progressing. Insulation measures the capacity of said material in restricting temperature rise on the unexposed side, therefore preventing radiant heat from igniting any sensitive media in adjacent rooms.

Stopping explosions, break-ins, and water damage

Sadly, fires are not the only hazards that data centres face. Electrical faults in heavy switchgear or backup generator rooms can occasionally result in sudden and catastrophic overpressure explosions. By integrating blast protection into the structural perimeter, you can ensure that the physical shockwaves from an external plant room explosion will not breach the server vault itself.

Then there’s the human risk. Data storage facilities hold highly valuable corporate and personal information, making them potential targets for physical intrusion. Steel faced panels can provide high-level security resistance from forced entry. Plus, this can be further expanded by utilising impact-resistent composite barriers to get a dual purpose shield, deterring physical attacks and maintaining absolute thermal separation.

The most often forgotten about aspect of a major fire incident is that of water damage. Emergency services use high pressure water streams to suppress the fire, adding to the already damp environment created by sprinkler systems. Many traditional fire rated materials absorb this water and will quickly lose their structural stability, especially when subjected to the high pressure water streams. Durasteel panels have been designed to withstand this and maintain their structural integrity and barrier performance, even when subjected to thermal stress, and then water force. This is vital for preventing wall breaches once the firefighting operation begins.

Don’t let cables and ventilation shafts become a weak point

Upgrading your server room fire safety can offer advantages beyond simply safeguarding data centres against worst-case incidents, providing benefits to various other areas of the site.

A complex network of power cables, data lines, and ventilation systems run throughout data centres and each of them, at different points, will need to breach the fire-rated perimeter, potentially creating weak points in the barrier.

Ventilation ducts themselves can be encased in fire-rated ductwork, to ensure that the cooling air pathway cannot become a conduit along which the fire can spread. These ducts are tested in the same manner as other fire-rated materials, to ensure that they will maintain their structure and containment properties, even under extreme conditions.

Power distribution cables generate heat even during normal operation, and as such can represent a notable fire risk. Enclosing primary cable routes in fireproof cable encasements ensures that an internal cable fault remains contained within the protective channel. It also protects critical data lines from being severed by an external fire, preserving the communication lines of the facility during an emergency.

Why all of this is vital for preventing business downtime

Fire protection is not cheap, but investing in advanced passive fire barriers provides clear advantages when used alongside physical protection, and not just in protection of the most important items during a catastrophic fire. Even minor events can disrupt a business and any prolonged downtime can destroy client trust and result in severe financial penalties. Recovering from a catastrophic hardware loss can take months, whereas containing a fire to its zone allows for a swift resumption of business operations.

It can cost you more in the immediate future too. Insurance providers are thorough when they evaluate the risk profile of a commercial property before setting its premiums. Demonstrating that your data centre utilises certified, high-performance passive fire protection systems can lead to reduced insurance costs. Insurers recognise that a facility built with robust compartmentation is far less likely to suffer a total loss event.
