Going beyond the Minimum – Fire Safety Standards

Evaclite outlines current thinking within the industry and how specifiers have new innovations in their toolbox that can ensure compliance…and beyond.

It is possible to design a building to comply with the standard codes of practice, as set out in Approved Document B (ADB) of the Building Regulations and the Regulatory Reform (Fire Safety) Order 2005 (or RRO)

But while the regulations provide a minimum standard of fire safety, for many building owners it is not simply about complying with the regulations.

Approved Document B has recently been updated to restrict the use of desktop studies or assessments in lieu of testing. This approach has been commonly used and is where previous test data is used to suggest how a system or materials will perform in the event of a fire. However, in reality, it is often impossible to accurately predict how it will react in practice as even small changes to the design or build up can significantly affect its fire performance. Similarly, what other systems and procedures that are accepted as the norm should we now be looking at?

Historical events have highlighted the need to not only ensure compliance with the regulations but have also opened up discussions on whether compliance with the minimum provides a solution for all?

An example of this is The King’s Cross Underground Fire on November 18th,1987. Most of the people that died, did so because they took the wrong route out of the station, they took an evacuation route that leads them into the path of the fire. Thirty two years on and now in the 21st century, with new technologies in adaptable, intelligent emergency exit signage, is it still acceptable for instance to be using dumb “standard” exit signs that can potentially lead people towards a hazard?

Is it even possible today to design a building that’s fireproof? Probably not 100%, and if it does burn it’s going to produce smoke, heat and toxic gases. Fire design engineering is also about making sure we can get people out of that structure as quickly and efficiently as possible, eliminating bottlenecks and directing people to the safest exits and avoiding smoke-filled corridors, as set out in BS5266-1 :2016 Annex B. Integration of building systems such as fire detection and emergency lighting can enable quicker, safer and more decisive evacuation.

Fire safety engineering is not just about compliance with a set of prescriptive codes, it is about developing performance-based solutions that are not only safer but can be cost effective without having to implement complicated systems or change the original design and thus satisfying the architect’s aspirations.

While the regulations provide a minimum standard of fire safety, the events of recent years have demonstrated the importance of going beyond the minimum to optimise the safety of building occupants.

Dynamic and Adaptive Signage: We Make No Secret Of Our Signs

Up until now, fire design engineers and fire risk assessors when specifying some type of “Smart” Emergency Exit signage to stop people entering a building or exit, have had to rely on old tech, essentially what is known as “Secret Signs”.

These are generally big black boxes placed above an exit door with an apparent dark fascia to the front. Once an alarm activation has occurred these boxes light up usually with a worded message such as “Do Not Enter”.

Talking to architects and installers of this type of signage, they all commented that these signs are ugly and bulky and do not blend into the aspirations of the building design. The worded message can also present language barrier issues during an evacuation. Sometimes they must install this type of sign and an emergency exit sign alongside, so essentially two signs.

At Evaclite we make no secret of our emergency exit signs. They are constantly in view, providing a compliant sign at all times. They have the ability to adapt to a given emergency situation and if the exit is no longer viable then a Red Cross will automatically appear across the fire exit sign and flashing Red LEDs attract the eye to the sign’s message. Similarly, if the exit is viable a Green pulsing arrow will appear within the white arrow pictogram of the sign. Being intuitive and with no words, they are easily understood by all languages.

Dynamic and Adaptive Emergency Exit Sign — “being detected twice as fast, and three times faster at decision making.”

So no more big, bulky boxes hanging from your airport concourse or prestigious new apartment building. It’s no secret that architects and installers prefer the Evaclite option. New IP65 signs are now available.

Dynamic and Adaptive Signage: Product Explanation

What is dynamic and adaptive signage?

Dynamic and adaptive signage is a very recent phenomenon. It’s still in development and newly emerging into the market, so people are only just beginning to get their head around how it works and why it’s effective. There’s a huge variety of acronyms around ‘dynamic’ signage, it’s been referred to as: dynamic, intelligent, adaptive, smart, among other terms. All of these terms essentially mean the same thing and they all lead to one unique selling point of the product. Instead of being ‘passive’ like the other fire exit signs on the market, they are both ‘reactive’ and ‘adaptive’ to their environment.

Up until now, when the alarms go off in most buildings, emergency exit signs don’t do anything more than they did before the alarm went off. They’re illuminated. They show you which exit to go to. The only problem is that the arrow is pointing to the right. That could be where the fire is, so this is a pain point that the Evaclite product targets and is able to solve. Currently, fire exit signs are passive and that’s the issue, Evaclite is making the move to dynamic signage.

How do dynamic signs work?

The signs have been made both adaptive and dynamic at the same time. The emergency exit sign is attached to the ceiling and connected to a smoke detector, which may only be a metre or two away from the emergency exit sign. This is one of the triggers for the sign to activate into adaptive mode. A fire engineer would then inspect the fire panel and do some cause and effect programming, this would determine if smoke is detected in a specific zone and acknowledge that we don’t want people going out of that specific exit, this would then activate a red cross to appear in the form of a 3 pulse array across the sign. This is now a negated X. It’s no longer a fire exit, but people are still able to see that it was a fire exit.

A lot of design for the product takes into account people’s behaviour. Evaclite could have flushed the red sign with a constant flashing X. But then this creates some confusion, is the sign faulty? Should we ignore the X? I’m not sure it’s working. This all cuts into valuable time and in a fire, the second’s matter.

Why use LED pulses?

To try and combat any confusion that could be caused by a flashing X across the sign, Evaclite uses LED lights that pulsate at the outer corners, so the sign is static yet eye-catching. It’s important to note that the lights aren’t just there for purely practical reasons, there is a psychological reason for the pulses. It’s intuitive and people have to instinctively understand the message without stopping to think about its meaning. The 3x pulsing array only activates when the alarm has sounded, ensuring that building occupants will not become too familiar with the concept, reducing the likelihood of learned irrelevance. The enhanced design also has the advantage of being fail-safe – if the LEDs failed to operate, the sign would remain compliant, as a standard passive emergency exit sign. The way the flashes present is from left to right, if you’re to follow the flashes with your head, you’re turning your head from one side to the other and saying ‘no’. This may sound a little simplified, but psychologically it’s another effective deterrent.

How do we know they work?

Evaclite have conducted a number of trials on the dynamic signs. Evaclite found that 60% of people don’t actually notice passive signs (standard emergency exit signs) during an evacuation. It all comes down to what is known as ‘learned irrelevance’. When you see something every day it loses its impact. It’s not something that’s relevant to you now, so you block it out and gradually this becomes a learned behaviour. During a trial conducted at the University of Greenwich. Participants had to run down a corridor with the passive signs present and the majority of people didn’t notice them, and if they did, they didn’t follow the way that the sign recommended.

Evaclite replicated that trial, and this time, they put in the dynamic exit signs, and received twice better detection. The majority of the people not only noticed but verbally acknowledged the signs. The key in this trial was the time it took to make the decision. In the first trial participants were spending on average 6 seconds deciding which way to go. However, when presented with the dynamic signs they didn’t stop and think they just acted, and these few seconds could be vital in the event of a real fire.

Why is this so important?

As we’ve said multiple times, if you’re in an emergency, every second is crucial. If you find yourself in a high rise building, you start to multiply the seconds and quickly the seconds turn into minutes and suddenly it’s been 10 minutes. This is really the USP of the product, reaction time. Although the design is brilliant and loved by architects the product focuses heavily on human behaviour and instinct to get you out of danger as quickly as possible.
