If the fire pump room already has backup lighting, is evacuation lighting still needed?

Thread Content

During a safety inspection, experts found that there was no emergency evacuation lighting in the fire pump room of a certain factory. The relevant personnel explained that backup lighting had already been installed, so there was no need for additional evacuation lighting; after all, the load rating of the backup lighting system is also quite high. Do you guys think that’s right? Let’s see what the standard says. \"General Code for Fire Protection in Buildings GB55037-2022\": \"10.1.11 Backup lighting shall be provided in fire control rooms, fire pump rooms, generator rooms, power distribution rooms, smoke control and exhaust systems rooms, as well as in rooms containing fire protection equipment that needs to continue operating during a fire. The minimum illuminance on the working surfaces in these areas shall not be lower than that of the normal lighting.\" It mentions backup lighting, but does not refer to evacuation lighting. Other clauses 10.1.8 and 10.1.9 of this standard address evacuation lighting, but do not mention the need for evacuation lighting in fire pump rooms. Is it that it’s not needed? There is another standard, the “Technical Standards for Fire Emergency Lighting and Evacuation Indication Systems GB51309-2018”. Clause 3.8.1 states that in areas such as refuge rooms (floors), switchgear rooms, fire control rooms, fire pump rooms, and generator rooms that must remain operational or manned in case of a fire, standby lighting, evacuation lighting, and evacuation indication signs should all be installed. ” This proves it. The provisions state: 3.8.1 In shelters (floors) and areas such as power distribution rooms, fire control rooms, fire pump rooms, and generator rooms that need to remain operational and staffed in the event of a fire, backup lighting, evacuation lighting, and evacuation signs must all be provided; in other words, backup lighting should not replace emergency fire lighting. Emergency lighting includes standby lighting, safety lighting, and evacuation lighting. What is emergency lighting for? When normal lighting fails, it provides a minimum level of illumination for general work areas, thereby meeting basic operational needs. Evacuation lighting is used to indicate the locations of safety exits, evacuation routes, and shelters, helping people to evacuate quickly and in an orderly manner in emergency situations. Evacuation lighting typically includes evacuation sign lights and lighting for evacuation routes. In fact, there may be other people in the fire pump room; firefighters need to stay, while the others need to evacuate, and this is where evacuation lighting comes in handy. Backup lighting is intended to ensure proper operations or prevent major accidents; it is not primarily designed for evacuation purposes. Even if used as a substitute, it may not necessarily meet the required illuminance distribution and response speed for evacuation.
