Urban planning changes to town and country planning

In recent years, rural fire safety situation remains very serious, the fire occurred, loss and casualties high fire safety in the village. New work from fire fire protection law, the adaptation of global and building new Socialist countryside, at the request of a harmonious society, dedicated to rural fire service, specific provisions identified local governments should strengthen rural fire service leadership, to take measures to strengthen public fire facilities construction, the Organization establish and supervise the implementation of responsibility for fire safety.

New fire protection law will be the fire method of "urban planning" was changed to "urban planning", "local people's Governments at all levels should include fire safety layout, fire station, fire service, fire, fire engines, fire equipment, fire planning into town and country planning, and is responsible for organization and implementation. Urban-rural fire safety layout does not comply with the fire safety requirements, it should be adjusted, perfect; public fire-fighting, fire protection equipment, inadequate or not adapted to actual needs, should be built, rebuilt, configuration or technical renovation ". A word of variable, "City" and "rural", reflects the work of the rural fire.

Construction of multiple forms of fire power

Fire prevention practice shows that the establishment of various forms of fire power is determined by China's national conditions, is the development and protection of the essential foundation of people's livelihood is well-off social requirement.

New fire law inheritance and development of a completely original fire services law relating to the construction of many forms of fire forces the creation of multiple forms of fire forces the overall requirements, the distinction between cities, towns, explicit construction of different forms of fire power requirements. Provisions of the "people's Governments at or above the county level shall, in accordance with national provisions on the establishment of public security fire fire brigade, allied, and in accordance with the national standard are equipped with fire-fighting equipment, fire fighting work. Township government shall, in accordance with the local economic development and the need for fire prevention, establish a full-time volunteer fire department, fire department, fire suppression work. "

Bear emergency rescue work

The 17th CPC National Congress proposed the "perfect emergency rescue system" requirement, which is to protect our country's economic and social development, security, development of important strategic tasks. Fire brigade as the maintenance of public security forces to bear many emergency rescue work, this is the common practice in the countries of the world and the development trend of the international community.

According to our emergency rescue force construction of actual needs, take full account of the fire brigade in active systems, equipment, training, management, and other advantages, as well as in recent years, the fire brigade emergency rescue work results, new fire protection law further strengthened by the fire brigade and Government allied fire brigade emergency rescue capacity-building and the necessary safeguards to provide public security fire service, Government, professional fire brigade in accordance with State regulations assume major disasters and other emergency personnel life-based emergency rescue work.

Specialized supervision "increase"

Have the right to have the responsibility, authority, infringement of the right to compensation, it is illegal to pursue, in accordance with the administrative and establish the rule of law and Government, responsible government requirement. In order to strengthen the fire protection supervision, new fire protection law specifically add "supervision" chapter, focus on norms and constraints on Government and Government departments, in particular the police and fire agencies exercise of the powers and strengthening of its supervisory duties according to law, the police and fire agencies supervise management also raised higher and more stringent requirements.

Perfect fire administrative sanction system

New fire protection law adapted to the needs of the development of the fire service, the relevant provisions of the legal responsibilities on a larger amendment to increase the intensity of the fire administrative sanction, supplementary improve fire administrative sanction system.

New fire protection law increases should be administrative punishment of violations of fire-fighting regulations of the Act, a solution to the original fire protection law for violating fire regulations do not provide full, not tight, some of the violations are not promptly halt, correct and punished according to law, maintain the seriousness and authority of the law.

New fire protection law adjusting the types of administrative penalty. New fire protection law set the warning, a fine, detention, be ordered to cease (stop construction, stop use), confiscation illegal obtained, be ordered to stop practising (revocation of the corresponding qualification, qualification) six types of administrative penalties, increased order ceased to practise (revocation of the corresponding qualification, qualification), a kind of administrative penalty on a number of serious violations of fire-fighting regulations of the Act in particular acts of endangering public safety an additional penalty of detention, the law of the deterrence.

New fire safety violations

New fire protection law new fire violations are: (1) fire design via public security fire agencies according to the random unqualified, not stop construction; (2) a construction works in use by police and fire agencies representing non-qualified according to the law, do not stop using; (3) construction units not legally will fire design document reported the fire services of public security organ for the record, or failing to report after the completion of public security fire agencies for the record; (4) the construction of the building design unit or building construction enterprises reduce fire technical standards for the design, construction, and (5) construction and design units do not follow the fire technical standards mandatory requirements for fire protection design; (6) construction supervision units and construction units or collusion, falsification of construction enterprises, construction quality to reduce fire; (7) the personnel-intensive sites in door and window effect escape and set on fire-fighting and rescue of obstructions; (8) production, storage and management of inflammable dangerous places and living place settings in the same building, or not and keep a safe distance from the place of residence; (9) the production, storage, operation and other items of place and a place to live in the same building that do not meet the technical criteria for fire fighting; (10) the illegal carrying flammable explosive hazard access to public places or by public transport; (11) hinder police fire agency personnel from legally performing their official duties; (12) in the fire stop alarm, or have reporting responsibilities of staff not timely alarm; (13) the unauthorized use of the seal or by publicAn Office fire agencies place, parts of sealed; (14) the personnel-intensive sites use unqualified fire products or countries explicitly eliminated fire products; (15) fire product quality certification, fire detection, fire technical facilities services agencies provide false, inaccurate file.

These acts, there is a fire works adjusted the new situation, some socio-economic development of the new situation, new problems, there is the recent serious fire accidents of highlight, there are also more prominent, the greater danger. Therefore, the provisions of the new fire protection law should be given to the corresponding administrative punishment.

Increase in temporary seizure measures

New fire protection law in the original fire legislation concerning compulsory measures on the basis of the practice of law enforcement, fire fighting increased temporary closure measures.

New fire law police fire agencies in fire inspection found the fire danger, it shall notify the entity or individual to take immediate steps to eliminate risks; not timely elimination of hazards may be a serious threat to public safety, police and fire agencies should follow the provisions on dangerous sites or places of temporary closure measures.

Police station fire supervision duties in accordance with the provisions of the

Our more than 60% of fires and more than 60% of fire deaths and injuries occur in rural areas and towns. Considering that the public security organs fire agencies only in people's Governments at or above the county level, and the public security organs established police station covering the vast rural areas and urban communities, new fire protection law gave the police station, fire supervision duties require police station can be responsible for the day-to-day supervision and inspection of fire protection, fire safety education and awareness.

【 Weak current College 】 smoke control in high-rise building facilities design and construction analysis of and solutions to common problems

Summary: on the tall buildings of smoke control system design and construction issues analysis and countermeasure
Keywords: tall buildings, natural smoke exhaust system
Usually tall buildings of smoke control facilities include smoke staircase and vestibule, fire the elevator room, combined with front room, enclosed stairway, refuge layer (room), and other places set of smoke, the basement, in the aisle, Atrium, no form or with fixed window room and set the smoke extraction facilities, smoke partition between the vertical wall of smoke. Smoke management facilities is tall buildings to protect life and property safety indispensable fire safety facilities, but as part of the design and construction personnel on smoke control facilities of structure, function, performance, lack of awareness, understanding of national regulatory standards, not often leads to the design, construction, there are some problems, mainly in the following areas:
A, natural smoke extraction facilities up to exhaust purpose
Natural gas is an economical, simple and easy operation, maintenance, management convenience of exhaust smoke, but as part of the works in the design and construction process is not carried out according to specifications, often lead to project completion, natural smoke extraction facilities do not have the effect of its smoke causes mainly has following several aspects:
A is the set of natural smoke exhaust was misaligned window. From natural smoke effect, exhaust window should be as close as possible to the top of the wall, there are a considerable number of natural smoke exhaust window is set in the upper part of the wall, but is lower, from the roof, the greater the distance from the ceiling, is not conducive to natural gas.
Second, natural smoke exhaust window window area does not meet specifications. National standards for the design of tall building fire safety norms on the use of natural smoke exhaust parts of fenestration area shall be clearly defined, but due to some designers do not press specifications carefully calculated, or the fixed window area within the exhaust window area, causing some projects don't exhaust window area to the specification requires that directly affect the smoke effect.
The third is the natural structure of exhaust window. Have made the smoke exhaust window is not open, fixed window, the upper portion of the form to make a fixed window, the window can be opened by the smoke in the lower portion of the window, seriously affect the smoke extraction functionality.
4. installation height high exhaust window missing easy to open the operating organization. According to specification, exhaust window should have opened the device easily, but some of the installation height high, difficult exhaust window are not installed on the negative operating device, fire smoke exhaust window opens.
2. set the mechanical pressurization smoke control equipment parts required to form a top pressure value, mechanical smoke extraction facilities of smoke effect is not evident.
Air and exhaust air, port Yu ya value does not meet the regulatory requirements of the phenomenon is more prevalent in the project, some air, exhaust port speed or even close to zero, this might be caused by more complex, mainly has following several aspects:
1. improper fan selection. According to specification, smoke staircase and vestibule, combined with front room and fire the elevator room of mechanical pressurization air flow, the calculation should be identified, when the calculated values and norms stipulated values do not match, whichever the greater value determines the design directly, according to the specification for a given value determines that often lead to the selection of the blower air flow, pressure is small, can not meet the requirements of the design uses combined ventilation and smoke extraction system, construction was not as designed selection two-speed fan; construction units not complying with the design of the fan model ordering, purchasing power specifications smaller fan, led to a serious shortage of fan.
2. mechanical pressurization system and natural gas facilities in the repeat settings. For building height more than 50 meters of a class of public buildings and buildings of more than 100 meters of residential buildings, in accordance with the requirements of the regulations should set mechanical pressurization system, some projects in this area while using natural gas, resulting in fire, mechanical pressurization system for smoke control window with nature while opening, smoke stairs difficult to form a positive pressure, can not reach the smoke effect.
3, combined with the positive pressure ventilation system was not designed pressure regulation device. According to specification, mechanical pressurization for smoke control staircase and combined with former room, to independently set the air supply system, when you must share a system should be on the way to the front room with air duct pressure difference set on automatic control device. There are many design combined with the positive pressure ventilation system does not have design pressure regulation device, unable to form a staircase of residual pressure is higher than the front room.
4. smoke partition not complying with the specifications set smoke facilities. A considerable part of the project, especially the large shopping centres set up smoke part not specifications set down in the ceiling smoke vertical walls, basement while using architecture beam for smoke, smoke extraction system in the exhaust vent is not according to specification, located in the ceiling or wall near the ceiling, which is located below the beam.
5. air settings do not meet the requirements. Some vertical smoke control system for air fixed louvres-normally open air outlet, outlet sizes basically the same, caused by the layer of air volume and air speed serious imbalances, far away from the fan supply outlet of the air flow is inadequate, even at the end of the diffuser of wind speed, wind rate close to zero.
6, duct shaft construction, air quality is poor. A considerable number of works by ventilation shafts not plastering, plumbing connections are not closed position, normally closed air leakage is not tightly closed, causing very serious air, exhaust air flow of wind speed, the specification requirements, construction unit or even cancel the shaft connection ceiling diffusers for air pipe, use ceiling stuffy air duct space instead of a top, often causing air duct outlet wind speed close to zero.
While some will exhaust system fan exhaust port is set in the Interior, fire smoke from indoor Interior to not only lose the smoke effect, but also may cause the spread of fire.
3. smoke fan of distribution does not conform to specification
One is the fan's power supply to the load level of tall buildings. Some of the power supply line not received since the fire power, but rather add to floor lighting, power distribution box, some design uses single circuit distribution lines, design is not set at the end of the power supply automatic switching device, not a secondary power supply load requirements, exclusive dual-circuit, located at the end of the automatic switching device.
Second, the downlead distributionInstallation of electric lines does not meet the requirements. Some smoke fan distribution line wear PVC plastic pipe, some wear metal tube not brushing fire retardant coating, does not comply with the wearing of fire performance requirements.
4. setting up machinery parts of smoke control facilities specifications set by
1, with podium of smoke control in high-rise building stairwell and front room, fire the elevator room or shared room, when the podium above use can be opened for natural smoke outside Windows, podium section does not have natural smoke condition, its front room or room is not in accordance with the former specifications set positive pressure ventilation system.
2. no more than 20 meters of natural gas in the aisle, some designers who connected smoke before room stairs have natural smoke, think it has the natural smoke conditions, according to the specifications set mechanical smoke extraction facilities.
5. strategies
In view of the above problems, I think the Fire Department should be from the following aspects to strengthen building smoke facilities design and construction supervision:
1, should strengthen smoke facilities design and construction of business mentoring and training. Around the Fire Department for fire alarm and General Electric, fixed (automatic) fire-fighting facilities design and construction of business mentoring and training attaches great importance to the training process often overlooked smoke facilities design and construction professionals.
2. should implement smoke facilities construction by fire facilities construction unit of the system. Smoke management facilities is building automatic fire-fighting facilities, an important part, in accordance with the provisions of its construction by fire facilities construction units, but there are many items of smoke control facilities construction by air conditioning unit is responsible for the installation of construction professionals.
3, fire supervision departments of the examination staff at construction drawing examination, should focus on smoke control facilities design review should focus on the natural smoke exhaust window settings, window size, mechanical smoke extraction facilities set parts, fan selection, the air exhaust port settings, smoke partition until the review, while in construction should be strengthened to smoke the supervision and management of facilities, smoke control facilities as construction supervision and inspection of important content, make timely detection of problems, guidance, supervision and construction units for rectification.
