Shenyang emergency fire lighting It is suitable for theaters, shopping malls, hotels, banks, hospitals, apartments, private air defense works, underground facilities and other places requiring uninterrupted lighting. In case of fire, earthquake and other natural disasters, please use emergency lights for refuge Disaster relief, etc. However, some people neglect this important equipment. Improper products and improper installation fill the potential security problems. Therefore, when purchasing products, do not choose unqualified products for small profits. Also, be careful when installing. To ensure a smooth escape in case of fire, please pay attention to the following:
The location, location and installation height of fire emergency lighting fixtures are clearly specified in the "High Level Regulations" and the specifications of relevant buildings, but some improper practices are still found in the review:
1. In many cases, enclosed staircases, smoke proof staircases, and evacuation passages are only equipped with electrodeless lights and guide lights, and no evacuation lights. Electrodeless lights and guide lights can be used as part of the evacuation lighting, but they often meet the requirements. Evacuation lights are usually installed under the wall or ceiling, which are relatively high. They are mainly used in the early stage of a fire. There are many evacuees. When a fire occurs, the smoke rises and diffuses, and is often blocked first. At this time, the low-level induction lights are not the same in time and effect. They cannot be replaced, let alone taken one. The article "Description" in the Code for Fire Protection Design of Civil Air Defense Works has a good analysis of this.
2. Escalators cannot be used as evacuation exits Marker lamp And relevant guiding lights or shopping guide signs in shopping malls, airport, station and other functional signs can not be included in the evacuation lighting system, but can be used. As an ordinary standby lighting power object.
3. The emergency light shall be installed near the often neglected evacuation passageway, front room fire alarm button, fire hydrant button, fire telephone jack and other fire-fighting equipment.
4. The upcoming "Low Level Regulation" also stipulates that evacuation stairs with more than four floors shall be marked with the floor at the obvious position of each stair landing, and shall not be blocked when the door is opened or closed. Article C.3.6 in the appendix of the "Civil Code" JGJ/T16-92 also stipulates that "the evacuation sign light in the stairwell should be installed at the corner or wall above the rest board, and the upper and lower floor numbers should be clearly marked with arrows and Arabic numerals. The purpose of these provisions is to inform people (including firefighters) of the location of the fire so that they can make decisions. Therefore, it is necessary to combine the floor indicator with the evacuation light. In most cases, no attention is paid to design.
5. Large public buildings have large area, complex floor plan, many fire compartments, many exits and many fire rolling shutters. Some designers did not specify the boundaries between fire compartments to which each emergency exit belongs., Moreover, the arrangement of light guide lamps for fire fighting is quite random, which may even mislead people to enter the exits of other fire prevention areas. When the fire shutter is lowered, the survivors are at a loss. In addition, it is difficult to install the light guide lamp. In shopping malls and other places, counters are all around, so they should be installed at a lower position. If it needs to be hung, the height should not be too arbitrary. If the installation is too high, it should be controlled within 2.20~2.50m. It is easily blocked by fire and smoke, affecting visibility.
6. For large civil air defense basements, it is difficult to design cross evacuation lighting, because there are some personal defense units, some fire compartments, and wartime exits are not the same as conventional exits The normal emergency exit should be blocked in wartime, while some of the wartime exit should be closed in peacetime. The distance between the wartime and peacetime guidance lights is different, and the direction is also different.
Many designs are mixed and expressed on a single drawing, with no difference in legends and no "note" added on the drawing. Therefore, it is necessary to advocate that the wartime and peacetime lighting should be plotted separately. On the premise of understanding the building discipline zoning plan, the boundaries of civil air defense, unit and fire compartment should be clearly indicated, so that all parties involved in design, review, construction and supervision can understand it, which can greatly reduce errors, It is also convenient for conversion and installation in battle. Of course, the relatively simple civil air defense basement can be clearly expressed with legends and illustrations, and can also be undivided.
