【 Weak current College 】 on Arcade fixed fire facilities of---Power By 【 China power house network 】

In recent years, with the scale of urban commercial establishments and the number of the shopping centre fire occurred and losses also rendered rise trends.　　Explore and research strategies for the prevention of Mall fire has become a top priority. First, the Mall kind of fixed fire facilities and its main function (1)
Arcade Fire-fighting facilities include fixed automatic fire alarm systems, fire control, fire hydrant system and automatic sprinkler systems, smoke, fire, emergency lighting, emergency broadcast evacuation signage, lighting, fire doors, fire shutter and fireproofing system linkage control system, etc. (2) main functions
1, alarm. Arcade heat, smoke, gas, hybrid detector able to fire, smoke from the burning heat and light radiation, physical quantity, into electrical signal that is transmitted to the fire alarm controller and at the same time show the fire site and log fire occurs. Arcade Fire sprinkler system in the automatic start sprinkling also can issue a fire signal.
2, the initial fire fighting. Arcade Fire sprinkler system, able to fire in the early days, up to a certain physical quantities automatically after the fire. Fire main pump automatic changeover, power distribution Cabinet of standby power can switch automatically to the indoor hydrant, fire box office and fire control, remote start, you can set the initial fire-fighting water gun position.
3. control of the fire from spreading and expanded. The Mall of smoke control system can effectively control the flow direction of the flue gas, mechanical smoke extraction system when the entrance of the flue gas temperature of more than 280 ° c, could be automatically turned off smoke fire dampers, prevent the proliferation of high temperature smoke caused by fires expanded; normally closed fire doors in the daily time remain closed, normally open fire door can automatically turn off the fire, the fire shutter automatically and manually start forming fireproofing, effective in curbing the spread of fire and expanded.
4. Security and safety of evacuation.　　Arcade mechanical pressurization smoke control facilities guarantees that the staircases 40-50pa pressure front room or shared room 30-25pa pressure, prevent the infiltration of the flue gas, the Mall of emergency lighting, emergency broadcast, lighting evacuation signs were trapped for fire safe evacuation. Second, the impact of fixed fire-fighting role played by the main reason for the adoption of this province, the investigation of a large shopping centre and many shopping malls fire analysis and demonstration, the author believes that currently fixed fire-fighting arcade cannot fully play its role in the prevention and disposal of fire a number of factors, but the main reason is the following two aspects: (a) the construction of fire-fighting facilities failing to comply with the prescribed procedures caused by deficient, make shopping centres do not have a fixed fire protection system design features
Individual construction units because of their special function did not fully understand, some construction work during construction due to insufficient funds or any other reason, feel free to change the design of programmes, arbitrarily cut fire facilities in certain projects, resulting in a lack of fire-fighting facilities, some units because of the interest-driven, one-sided pursuit of low prices, while neglecting the quality of products, resulting in fire-fighting facilities at work process often fails. (Ii) the fixed fire-fighting arcade daily management are not in place, their prevention and extinguishing of fire and give full play to the
Number of units installed on the Arcade Fire confined to police and fire departments to review and acceptance, periodic checks, maintenance, upkeep, resulting in some facilities often work with fault: construction units fire expertise, coupled with weak units staff training and awareness is not enough, the fire so that technology with a high level of fire-fighting facilities exist in name only. 3. make full use of the fixed fire-fighting arcade of basic strategies based on actual examples of fire analysis and research, the authors recommended that system design, quality inspection, construction, auditing, inspection, day-to-day management, and several links, do the following: (a) design of building fire facilities must comply with the national fire regulations and technical specifications
New, alteration, and expansion of engineering and construction projects, design units must be in accordance with relevant State regulations and technical specifications for fire to fire design, cannot lower the standards; the actual fire design often occur with defects and problems of leakage, fire design must be equipped with related fire technical theoretical knowledge and practical experience of professional staff, certificates, should strengthen the fire protection regulations and technical specifications of learning and on fire qualified engineering and research work, fire supervision departments shall regularly conduct on fire safety design personnel-related business training and design qualification review. (Ii) strict construction of fixed fire-fighting product quality
Various types of building fire facilities must be chosen by the national fire protection products quality inspection agency inspection qualified products, with the appropriate inspection bodies and inspection certificate and the factory certification; specification size deviation should be consistent with existing standards, must be a high-quality long lasting products that can be used, should have compatibility and stability, and effectively coordinated.　　　Firmly to eliminate the use of those properties are not stable, quality of inferior products. (C) the installation of fire-fighting facilities must comply with fire safety requirements, to achieve the necessary reasonable and well-equipped
Construction unit should be building fire design drawings and related information submitted to firefighting agencies audited unaudited or audited not qualified, the construction of administrative authorities shall not grant a construction permit, construction unit shall not construction; audit, should strictly follow the requirements of the original design, and construction of the building project sync because of insufficient funds, or for any other reason, feel free to change the design of programmes, arbitrarily cut fire facilities in certain projects, at the same time, you must use a certain technology strength, fire-fighting installation qualification of construction units.　　Stop using the low level of installation technology, the quality is poor, not responsible for the construction team to ensure a smooth installation of fire protection installations, test, acceptance. (4) fire departments should keep a tight control on audit inspection clearance
Before construction, public security and fire fighting supervisory body to submit to the construction of the building fire safety design drawings for strict audit, at the same time, to the construction unit of the quality assurance system intoLine checks, do not have the construction qualifications and construction units to resolutely stopped construction, at the same time strict construction qualification examination and approval procedures; fire-fighting installation has been completed, as designed on strict acceptance of project quality, necessary to make some fire equipment, fire simulation test to detect whether it is consistent with the design and the fire code requirements. (V) sound management system, ensure that the fire-fighting facilities at all times in good running condition
With fixed fire-fighting facilities of major shopping malls, to establish and strengthen the special fire safety management of institutions, facilities. Main responsible shopping malls as fire safety first responsible person, Arcade Fire facilities responsible for safety at work, to regular meetings of fire-fighting facilities existing problem, solution, as well as improving and strengthening of measures and is responsible for the Organization on the shopping centre staff knowledge of fire safety education, various forms of fire business training, universal access to prevention, fire fighting knowledge so that they understand and master the fixed fire-fighting facilities performance and usage; malls fixed fire-fighting facilities management staff should have strong sense of responsibility, a higher education degree, a certain expertise in engineering and technical personnel, certificates, responsible for fixed fire-fighting technology overhaul, maintenance and troubleshooting; building on duty, inspection, operation, archives, testing, and maintenance of the system, the fire-fighting facilities management are implemented to ensure that the facilities at all times in good condition.
