15、 SANS 10114 is not applicable to private domestic premises, its provisions can be applied to common access routes within multi-storey dwellings. 1.3 This part of SANS 10114 is not applicable to techniques that, when used in escape routes in addition to conventional emergency lighting luminaires, can
16、 enhance the effectiveness of the escape routes. NOTE This part of SANS 10114 should be read in conjunction with the requirements of the Building Regulations (SANS 10400) as well as the Environmental Regulations in legislation (see foreword). Amdt 1; amdt 2 2 Normative references The following stand

36、rgency lighting that is provided to enable normal activities to continue substantially unchanged 4 Objectives 4.1 General 4.1.1 For the purposes of this part of SANS 10114, emergency lighting is regarded as a generic term that covers a number of specific forms of lighting, as shown in figure 1. Figu
37、re 1 Specific forms of emergency lighting 4.1.2 The objective of emergency lighting is to ensure that lighting is provided promptly, automatically and for a suitable time in a specified area when the normal power supply to the normal lighting fails. 4.1.3 The objective of escape route lighting is to
38、 enable people to exit safely from a location by providing appropriate visual conditions and indications of direction pertaining to escape routes (see 5.1.1.3(a) to (g) and to ensure that fire-fighting and safety equipment can be readily located and used. SANS 10114-2:2009 Edition 1.2 7 4.1.4 The ob
39、jective of open area anti-panic lighting is to reduce the likelihood of panic arising and to enable the safe movement of people towards escape routes by providing appropriate visual conditions and indications of direction. 4.1.5 The objective of high-risk task area lighting is to contribute to the s
40、afety of people involved in a potentially dangerous process or situation and to enable proper shut-down procedures to be carried out for the safety of other people in the location. 4.2 Visibility considerations Vision varies from one person to the next, both as a result of the amount of light requir
41、ed to perceive an object clearly and of the time taken to adapt to changes in the illuminance. In general, older people need more light and take a longer time to adapt to the low illuminance along an escape route. 5 Lighting requirements NOTE The requirements given in this part of SANS 10114 constit
42、ute a minimum for design purposes and are calculated for the full rated duration of operation and for the end of design life of the equipment. The contribution of reflected light to illumination is ignored. 5.1 Emergency escape lighting 5.1.1 General 5.1.1.1 To provide enough visibility for evacuati
43、on purposes, lighting is required. Luminaires should be mounted at a height 2 m to 2,5 m above floor level. Illuminated signs, which shall be provided at all exits intended to be used in an emergency situation and along all escape routes, shall be so illuminated that they indicate the escape route u
44、nambiguously. 5.1.1.2 Where an emergency exit is not in direct view, an illuminated directional sign (or series of signs) shall be provided to assist the progression of people towards the emergency exit. 5.1.1.3 An escape lighting luminaire that complies with SANS 1464-22 shall be sited to provide a
45、 minimum illuminance of 5 lux for a horizontal distance of 2 m from each exit door and also where it is necessary to emphasize the existence of potential danger or the location of safety equipment. Amdt 1 Escape lighting luminaires shall be provided at the following: a) each exit door intended to be
46、 used in an emergency; b) near stairs so that each flight of stairs receives direct light; c) near any other change in level; d) where mandatory emergency exit and safety signs are installed; e) at each change of direction; SANS 10114-2:2009 Edition 1.2 8 f) at each intersection of corridors; g) out
47、side and near each final exit; h) near each first aid post; and i) near each piece of fire-fighting equipment and each call point. The positions denoted in (h) and (i), if not on the escape route or in an open area, shall be illuminated to at least 5 lux at floor level. 5.1.2 Colour identification I
48、n order to identify colours on safety signs, the minimum value for the colour rendering index Raof lamps used in emergency lighting systems shall be 40. The luminaire shall not substantially detract from this. 5.1.3 Duration The duration of operation (see 3.3) shall be at least 60 min. 5.1.4 Glare 5
49、.1.4.1 Disability glare shall be kept low by limiting the luminous intensity of the luminaires within the field of vision. 5.1.4.2 In the case of level escape routes, the luminous intensity of the luminaires shall not exceed the values given in column 2 of table 1 within the zone 60 to 90 from the downward vertical at all angles of azimuth (see figure 2).
