18 Essential Siting Of Emergency Luminaires BS5266 pt 7:1999 n EXIT DOORS (Intended for use in emergency) Within 2 metres horizontal distance

19 Essential Siting Of Emergency Luminaires BS5266 pt 7:1999   External escape routes may need lighting   Consider muster points / roll calls Within 2 metres horizontal distance

20 Essential Siting Of Emergency Luminaires BS5266 pt 7:1999   STAIRS / ESCALATORS   FLOOR LEVEL CHANGES / MOVING WALKWAYS   Each tread should receive direct light   (Painting stair nosings in a light colour can assist safety)

23 Essential Siting Of Emergency Luminaires BS5266 pt 7:1999 Within 2 metres horizontal distance NB - 5 lux minimum on floor if not on escape route FIRST AID SAFETY SIGNS & EQUIPMENT

24 Emergency Signs BS EN 50172:2004 Required to ensure ESCAPE ROUTES are APPARENT from ANY LOCATION Series of signs may be req’d. MAINTAINED where occupants will be unfamiliar with building layout

25 Sign Formats & Status Now ILLEGAL (since 1999) UK PREFERENCE BS5499-4:2000 (wht man – internally lit / green man externally lit.) MOST COMMONLY AVAILABLE SI341 HSE Signs Directive Format NB All signs should be of the same format HTM65 – NHS HOSPITALS

26 Externally or Internally Lit? BS5266 pt 7:1999 h EXTERNALLY LITINTERNALLY LIT 100 X h ( 15m?) 100 lux vertical illumination (mains) and 5 lux (battery) (Minimum values) 200 x h ( 30m?) > 2 cd/m 2

27 Signage

28 Direction Arrows: BS5499-4:2000

29 Luminaire Photometric Data BS5266-1:2005 Spacing Tables via Dialux

30 Direct light only BS5266-1:2005 zero reflection factors for all surfaces

31 Uniformity Requirements Escape Routes & Open Areas BS5266 pt 7:1999   Max : Min = 40 : 1   Escape Route 40 lux/1 lux   Open Area = 20 lux/0.5 lux

32 Individual Luminaire Failure BS EN Minimum 2 luminaires per compartment (where practical) Use more low powered luminaires rather than fewer higher powered

33 Avoiding Disability Glare BS5266 pt 7:1999

34 Conclusions BS5266-1:2005   Client’s Fire Risk Assessment should be consulted   Guidance needed on requirements over minimum levels and locations   Points of emphasis need to be finalised!   Designer undertakes legal responsibility! (Signed Declaration of Conformity req’d)

38 Maintained or Non Maintained ? BS5266-1:2005   Maintained Exit signs when building users will be unfamiliar with its layout.   Maintained within common circulation areas of shopping malls.   Maintained usually saves installation points (regular luminaires converted)   Lamp Integrity needs close attention   Temperature/Battery life issues

39 Luminaire Specifications BS EN   CE Marked: declaring compliance with all relevant standards   (Tech File includes EMC test certification)   Makes site conversions very dubious

40 LEDs  Light output now high enough  Long life  Low power consumption

41 LED Exit Signs  100,000 hr life = over 11 years continuous illumination  NiMh batteries – 8 years rated life

42 Agenda 1.Legislation/Standards/Guidance 2.Design Requirements 3.Equipment – latest developments 4.Ownership 5.Automatic Testing Products and Systems 6.Summary

43 Good Housekeeping! As part of a Safety Culture: Regular Inspections/Maintenance and Risk Assessment Reviews Escape Routes permanently unobstructed No locked/blocked exit doors

44 Servicing   Regular servicing is essential   “Responsible Person” should appoint a “Competent Person” with authority to ensure correct testing/maintenance/logging

45 Inspection & Testing BS EN 50172:2004  Commissioning Full 3 hour duration (after 24 hours uninterrupted charge time)  Monthly Short test to ensure emergency lamp functionality  Annual (NEW, was after 3 years) Full rated battery duration test

46 Agenda 1.Legislation/Standards/Guidance 2.Design Requirements 3.Equipment – latest developments 4.Ownership 5.Automatic Testing Products and Systems 6.Summary

47 Autotest Products & Systems  Product Standard  BS EN 62034:2006 – Standard for Automatic Test Systems

48 Basic Principles  Self-monitoring  Timing Circuit  Charging  Lamp  Communications  Compliant test schedule  Test result status indication  Minimise risk by randomising/staggering testing

49 Solutions  Stand-alone Luminaires  Network Systems

50 Stand-alone Luminaires & Exit Signs  Each device tests itself  Indication by status LED  Use of bi-colour LEDs  May use audible sounder  Test procedure – automatic but results need to be recorded manually every 30 days Healthy Flashing Red = Faulty

51 Stand-alone  Advantages  Easy to specify  Easy to install  Simplifies testing procedures  Reduces possibility of error  Disadvantages  Increased cost – typically £30 - £40  User has to remember to inspect on a regular basis  Test results need to be manually recorded

52 Networked Monitoring Systems  Luminaires & Signs linked back to central monitoring & reporting device  Luminaire, zone & central status indication  Detailed test reports  NOT rely on central device to initiate emergency mode

53 Latest Generation Technology  Remote reporting using web/  Pro-active – system lets you know when there’s a fault  Multiple Buildings  Fault identification  Reduces time spent diagnosing fault  Helps ensure maintenance engineer arrives with correct parts  Records Archive

54

55 Networked Systems  Advantages  Constant self- monitoring  Central status indication speeds up inspection process  Test results are prepared/stored automatically  Pro-active – ideal for remote monitoring  Disadvantages  Increased capital cost  Installation of signal cable & zone/central controllers – not so easy to retrofit

56 Summary  Stand-alone  Easier to specify & install  User must still inspect every month  Manual record keeping  Networked systems  Simplifies inspection – usually to one central location  Significant reduction in test/inspection costs  Automatic record generation & archiving  Pro-active remote reporting

58 Capital Outlay Option 1 – Standard Emergency Luminaires Option 2 – AutoTest Emergency Luminaires Option 3 – Networked System Cost of Equipment & Installation £ 15,000 £ 19,000 £ 21, %127%145%

59 Annual Testing Costs Option 1 – Standard Emergency Luminaires Option 2 – AutoTest Emergency Luminaires Option 3 – Networked System Annual Testing Cost £ 3,000 £ 1,500 £ 600 Total over 10 years (3% infl. pa) £ 34,400 £ 17,200 £ 6, %50%20%

60 10 yr. Life-Cycle Costs Option 1 – Standard Emergency Luminaires Option 2 – AutoTest Emergency Luminaires Option 3 – Networked System Equip. & Inst £ 15,000 £19,000 £ 21, yr Testing £ 34,400 £ 17,200 £ 6, Yr Life Costs £ 49,400 £ 36,200 £ 28, %73%57%

61 Life-Cycle Costs Graph

62 Summary  Modest increase in capital outlay = large saving in testing/inspecting/ recording through life of building  Greater peace of mind, compliance & security

63 Conclusions  Statutory requirement to provide effective emergency lighting  Code of practice specifies requirements  Client’s Fire Safety Risk Assessment should be consulted  Technology can provide solutions  Life-cycle costs should be calculated, not just capital expenditure
