Emergency Lighting Lighting that is designed to operate during power failure Fire causing failure of mains? Generally 2 main types Open area lighting Escape route signage Will operate as set up during initial site risk assessment Copyright 2017 BSI. All rights reserved 5 09/03/2018

Emergency Lighting More recently has shifted toward LED technology Allows smaller, more discreet, luminaires Power consumption reduced Gives possibility of longer duration operation times Copyright 2017 BSI. All rights reserved 6

Central Battery Systems (CBS) Luminaires can be self contained (have their own batteries) or powered from a central point. Typically large cabinets of batteries. Power routed around the building to supply luminaires. Copyright 2017 BSI. All rights reserved 7 09/03/2018

Central Battery Systems (CBS) With smaller loads due to LED products these are shrinking and becoming more modular rather than one central point. Space issues removed and risk reduced Copyright 2017 BSI. All rights reserved 8 09/03/2018

Routine testing of emergency lighting Traditionally a manual task Dependent on someone carrying it out to a schedule Faults may not be detected in between tests/ inspections Becomes difficult in complex buildings Copyright 2017 BSI. All rights reserved 10 09/03/2018

Automatic test systems (ATS) Clear indication and status of the whole emergency lighting scheme. Automatic scheduling of tests Faults indicated within 24hrs Central reporting and recording Copyright 2017 BSI. All rights reserved 11 09/03/2018

Third Party Certification For such important systems there is a need to ensure everything is correct, compliant and works. This is where certification from independent third party CBs (certification bodies) like BSI comes in. These organisations often have a certification mark as BSI does with Kitemark Copyright 2017 BSI. All rights reserved 12 09/03/2018

Kitemark Process Type testing Initial Factory Assessment Continually reflecting the changing world In terms of: Standards Accidents Regulations Technology Market expectations Many certification schemes end here. They are a one-off process and do not offer much assurance for product supplied in the future. Scheme updating Audit testing of the product Regular Factory Inspections CONTINUAL ASSURANCE Copyright 2017 BSI. All rights reserved 13 09/03/2018

Evolutions in Emergency Lighting Significant development in emergency lighting LED technology Automatic testing More system focused rather than stand alone Still very passive with regards to what it does Copyright 2017 BSI. All rights reserved 14 09/03/2018

Dynamic Signage Systems (DSS) 15

What if our safe place is no longer safe? Could our static signs become less useful? 17

European Commission Study - Human Factors People tend to retrace their steps to evacuate rather than follow signs Only 38% actually notice the signs!! In complex sites with multiple routes, these behaviours can lead to loss of life (as in King s Cross Fire - 1987) even with legally compliant signage. 18

Dynamic Signage Systems 1) System takes real-time inputs from the world such as: Smoke detectors? Fire and heat sensors? Human security operatives? Video capture and image recognition? 19

Dynamic Signage Systems 2) System has intelligence to interpret real-time events and determine the optimum escape routes from within the building. 20

Dynamic Signage Systems 3) System adjusts signs to illuminate the path to the optimum escape routes from the building. 21

Example 1 22

Dynamic Signage Systems EU Funded in response to Kings Cross & Dusseldorf fires Studied by Fire Safety Engineering Group - University of Greenwich GETAWAY project 2011 to 2014 Researchers developed intelligent DSS During trials in London and Barcelona metro systems, DSS: Improved the decision time to select an exit Increased percentage choosing viable safe exit routes Systems are now commercially available from many suppliers 23

Commercial Dynamic Signage Systems 24

Issues around choosing Dynamic Signage Systems Currently no agreed standards for these systems Potential for misunderstanding range of symbols Defined safe state default position? Greater requirements for autonomous decision-making How do you know which system to trust? 25

How BSI is addressing the challenges Standards lag technology Potential for misunderstanding Defined safe state Industry focus group Need to make use of existing agreed standards as far as they can reasonably be applied to DSS IEC 60598 Series (Luminaires) EN 62034 Auto Test System EN 50171 Central Battery System Greater requirements for autonomous decision making systems built into hardware and software Principles of IEC 61508 functional safety 26

Summary The humble emergency luminaire is changing rapidly LED technology and central systems are bringing operational benefits Dynamic systems with intelligence can help in complex scenarios New threats and risks accompany many of the new technologies BSI continues to innovate and support industry in risk management Our Kitemark brand will continue to provide assurance well into the future 27
