Emergency Lighting InstaHation:The complete emergency lighting installation forms part of this contract and must besupplied and installed in accordance with SANS ()114-2. The emergency lightinginstallation shall include the following:Emergency escape lightingEmergency lighting that provides illumination for the safety of people who areleaving a location on the premises or who are attempting to terminate a hazardousprocess before leaving the location.Emergency escape route lighting.Emergency lighting provided to enable people to exit safely from an area byproviding visual information on the direction and exit points and safety equipment.High risk task area lighting.High risk task area lighting is provided in order for people to safely shut downpotentially dangerous equipment or processes during a failure of the main powersupply.Open area anti-panic lighting.Emergency lighting provided in large outdoor areas to prevent panic in the event of apower failure and if necessary to provide for the safe movement of people towards theexit points.4. Escape route requirements:In the case of escape routes of width up to 2m, the horizontal illuminance on the flooralong the centre line of the route shall be at least 0,3 lux. Escape routes of widthexceeding 2m can be treated as a number of strips each of width 2m, or they can beprovided with open area anti-panic lighting. In the case of horizontal illuminance, theratio of the maximum to the minimum illuminance shall not exceed 40:1 along thecentre line of the floor of the escape route. The escape route lighting shall activatewithin 25s to 30s of the failure of the normal lighting and shall reach the requiredilluminance within 60s.In the case of open area anti-panic lighting the horizontal illuminance shall be at last0,5 lux at the floor of the empty area and at a height of up to 0,5m on the perimeter ofthe area. The ratio of the maximum to the minimum illuminance shall not exceed 40:1.The open area anti-panic lighting shall activate within 25s to 30s of the failure of thenominal lighting shall reach the required illuminance within 60s.In areas where high-risk tasks are undertaken, the average horizontal illuminance shallbe equal to that demanded by the task. During emergency situations it shall be at least10% of the normal lighting level or 20 lux, whichever is the greater, abnd shall befree of any harmfull stroboscobic effect. The ratio of the illuminance measured at thetask to that measured at a horizontal distance 5m from the task shall not exceed 10:1The duration of operation shall be at least 30 min, or the period for which people areat risk, whichever is the greater. High-risk task area lighting shall either permanentlymaintain the full required illuminance, or that illuminance shall be reached within 0,5sdepending on the task.5. Emergency escape lichtinc：GeneralLuminaires should be mounted at a height 2m to 2,5m above floor level. Illuminatedsigns, which shall be provided at all exits intended to be used in an emergencysituation and along all escape routes, shall be so illuminated that they can indicate theescape route unambigously.Where an emergency exit is not in direct view, an illuminated directional sign shall beprovided to assist the progression of people towards the emergency exit.An escape lighting luminaire that complies with SABS 1464-22 shall be sited toprovide a minimum of 5 lux for a horizontal distance of 2m from each exit door andalso where it is necessary to emphasize the existance of potential danger or thelocation of safety equipment.Escape lighting luminaires shall be provided at the following:a) each exit door to be used in
