Author : Time : 2018-03-02
As a pillar industry in local economic construction, Fujian's footwear industry plays an important role in helping local governments to find employment and increase tax revenues. Therefore, the development of footwear industry has always been encouraged and supported by the government.
But at the same time we also see the footwear industry currently exists fire hazard. Still remember the night of October 21, 2007, Putian City, Fujian Province, Shiyu Island Shitou Zhen Feida vamp factory suddenly caught fire, the raging fire eventually led to the tragedy of 37 people died, temporarily shocked the country.
November 24, Shishi Bao sent a town shoe factory fire, resulting in millions of dollars in economic losses, which is the last month of 21 in Putian City, "triple play" of the nature of the Feida uppers workshop occurred 37 death 19 injuries after the extraordinary safety accident in Fujian footwear industry. November 26, Fuzhou Crayon Lei Village another shoe factory fire, but fortunately these two fires did not cause casualties. Continuous fire accidents, Fujian footwear safety situation is alarming.
In order to better ensure the normal operation of footwear manufacturers, and to ensure the safety of footwear workers, National Anderson Fire Technology (Xiamen) Co., Ltd. try to analyze the footwear industry from the fire hazards, put forward the appropriate fire, fire prevention measures for readers reference.
First, the characteristics of footwear fire
According to the shoe production characteristics and the actual level of actual management, shoe fire hazards mainly in the following areas:
1, flammable, flammable items, fire load. Footwear in the production process, the use of a large number of PVC leather, PU leather, non-woven fabrics, nylon cloth, paper and other combustible items, and toluene, solvents and other flammable and explosive items, these items are easily lead in use A fire broke out. Moreover, the combustion of these articles will generate toxic gases such as carbon monoxide, sulfur dioxide, cyanide and nitrogen oxides, posing a great threat to the lives of employees. Some shoe factories due to the smaller factory area, not set up an independent warehouse, workshop and warehouse mixed, or even stacking shoes in the evacuation routes, in a fire situation, can easily lead to fire camp situation.
2, staff-intensive, lack of evacuation width. As a labor-intensive enterprise, the shoe industry uses a large number of skilled workers in sewing, semi-finished products, blanking and forming processes. In order to ensure fire safety, the required plant must have a certain evacuation width, but the actual situation is serious shortage of the shoe factory evacuation width, failing to meet the regulatory requirements. For example, a five-storey factory building with a single-storied building area of 2,000 square meters and 800 workers in a five-storey sewing machine workshop shall be built. According to Article 3.5.4 of the Code for Fire Protection of Building Design, For 1 meter, the total evacuation width of 800 workers should be 8 meters, but the actual evacuation width of the workshop is only 3.6 meters, only reaching 45% of the stipulation. In the event of a fire, they often cause evacuation difficulties. In addition, most of these workers did not undergo fire safety training prior to their appointment. They lacked the necessary knowledge on fire prevention and escape and had poor self-help capabilities. In the event of a fire, they could easily lead to serious consequences of casualties.
3, building fire prevention facilities are inherently inadequate. A large part of the shoe factory is leased to other factories for production. These factories do not have the fire inspection, acceptance and fire hydrant house, fire pump room and indoor and outdoor fire hydrant which are not necessary, and fail to meet fire safety requirements. Some fire extinguishing equipment configured by shoe factories is also used to extinguish B, C class fire sodium bicarbonate powder fire extinguishers, the existence of the wrong model, the number of issues such as the lack of fire after the use of these fire-fighting equipment is very difficult to start an effective fire fighting, resulting in Fire caused by a small fire, resulting in irreparable economic losses.
4, the layout of electrical wiring is not standardized, lighting selection error. The number of electrical equipment, lighting fixtures and distribution lines in the unit is large and widely distributed. However, most of the electrical wiring and equipment in the factory are installed by non-professional electrician, there are chaotic random connection of electrical lines, switch fuse cross-section and air switch rated work Current is too large, the motor phase-phase operation, switch under the stack switch combustible materials, the use of fluorescent lamps in the warehouse lighting and other issues, these are the hidden dangers of electrical fires.
5, warehouse fire safety management chaos. Raw materials, finished products warehouse is an important part of the shoe production unit, but the owners often only focus on anti-theft measures, but ignore the fire safety, there are more fire hazards, mainly in: First, the warehouse and workshop mixed without effective fire separation ; Second, irregular storage of goods in the warehouse, stack distance, lamp spacing does not meet the "fire safety management regulations" requirement; Third, there is no special warehouse for dangerous goods, not implemented in the classification of storage, warehouse middle warehouse A, Fourth, the use of open-type freight elevators within the warehouse, destroying the fire district of the warehouse; Fifth, no check-in check-in system has been set up, and it is easy to bring the hidden troubles into the warehouse.
6, overload operation easily lead to accidents. Footwear is generally produced according to the order, time is tight, the task is heavy. To complete the order task, the owners often require employees to work overtime, mechanical equipment overworked for a long time, workers can not keep up, "people sleepy" situation is more prone to fire safety accidents.
Second, preventive measures
For the footwear industry, fire hazards, some owners due to the lack of fire safety common sense, which do not recognize the fire risk, while others are lucky, do not attach importance to fire fighting, rectification of the fire hidden attitude is not positive. In order to effectively eliminate the fire hazards of the footwear industry, to protect the lives and property of owners of property safety, to ensure the smooth progress of local economic construction, the author believes that the government should strengthen the leadership of the footwear industry in fire safety, public security agencies to strengthen supervision and inspection of fire, shoe consciously fulfill Fire safety responsibilities of these three aspects, work together to do a good job in the shoe factory fire safety.
First, the government needs to strengthen its strong leadership mechanism as follows:
Strengthen the leadership of fire safety and ensure leadership is in place. Public security fire control agencies to promptly report the fire hazards of the shoe production units to the local government to obtain the government's attention and support for fire prevention work. The government earnestly strengthens the leadership of the fire safety work in the footwear industry and organizes the Economic and Trade Bureau, the Township Enterprises Bureau, the Safety Supervision Bureau, the public security fire department and other relevant departments to carry out the special fire safety management work for the footwear industry. Through concerted efforts and joint enforcement, Urged owners of shoe factories to take effective measures to rectify fire hazards; at the same time, they should give full play to the media supervision functions of news media such as television and newspapers, vigorously publicize positive examples of rectifying and reforming fire hazards, resolutely expose units that have been exposed to long- Encourage advanced, spur the purpose of promoting the shoe factory to promote fire safety in-depth work.
Second, the public security fire agencies to perform a good supervision and inspection, the content is proposed as follows:
1, increase fire supervision, to ensure law enforcement in place. In carrying out the work of special fire safety footwear management at the same time, public security fire agencies to organize the footwear industry to conduct serious supervision and inspection, the existence of the fire hazards to be issued in time legal instruments to inform the owners to take measures to eliminate hidden dangers within a time limit. At the same time, based on the principle of "strict law enforcement, enthusiastic service", according to the actual situation of the shoe factory, we actively help the owners to formulate feasible rectification plans that can rectify and deal with the fire hazard with less capital investment, Cause too much impact. For example, the use of natural lakes, rivers, groundwater wells as a firefighting cistern for shoe factories, adjust the floor of the workshop, try to make the staff-intensive needle car, blanking workshop located in the first floor, second floor of the plant. For those who refuse to rectify the hidden dangers of fire enterprises, public security fire agencies to effectively fulfill their statutory responsibilities, make full use of sufficient laws and regulations severely punished to completely solve the safety evacuation, the establishment of dangerous goods warehouse, shop and warehouse fire separation, building fire Facilities and other hard problems, and resolutely prevent and curb the footwear industry, the occurrence of a major catastrophic fire accident.
2, according to the requirements of establishing the system, urge the system to put in place. In the process of strengthening supervision and inspection, the public security fire protection agency should focus on Article 4 of Chapter 1 of the new "Fire Prevention Law of the People's Republic of China" to help the owners to establish a true sense of the subject of fire safety responsibility. The owner shall, in accordance with the provisions of this content, voluntarily perform the duties of fire safety and cooperate with the fire department to carry out fire prevention work to establish a set of internal fire safety management mechanisms for enterprises with "safety self-examination, self-concealment, self-responsibility and supervision" Self-defense and self-help ability.
Third, enterprises should focus on the establishment of fire safety agencies, internship fire exercises, the effective procurement of fire products and use, reflected in:
(1) implement the fire safety responsibility system. Enterprises should be based on the characteristics of footwear production, establish and improve fire organizations, identified from the factory department, workshop, warehouse to the team responsible for fire safety, clear fire safety responsibilities, implementation of fire safety responsibility system, organize the development of fire inspections, inspections, Safety evacuation facilities management, fire hazard rectification, fire, electricity management, flammable and explosive hazardous materials and places of fire and explosion, warehouse fire safety management, fire emergency evacuation plans drills, and electrical equipment inspection and management of fire safety management system , The development of fire safety equipment to protect a variety of operating procedures and raw materials, finished products warehouse, use, storage of flammable and explosive dangerous goods venues and staff intensive workshop identified key parts of fire safety, strict implementation of the management.
(2) Seriously carry out fire inspection. Enterprises should conduct a fire inspection at least once a month, focusing on checking the operation of indoor and outdoor fire extinguishing systems, fire extinguishing equipment configuration and effectiveness, the use of fire, electricity without violation, safety evacuation facilities, warehouse fire safety management, and easy Explosion-proof dangerous goods and places of fire and explosion prevention measures, and to determine the enterprise fire managers, plumbers and security personnel to strengthen the night inspections of fire-fighting workshops, warehouses, timely rectification of illegal behavior, proper handling of fire hazards, to ensure that enterprises, especially Fire safety when working overtime during rush hours.
(3) increase the intensity of rectification of hidden dangers. Business fire inspection found hidden danger of fire or public security fire agencies ordered to correct the fire risks within a time limit, business owners should be funded, staff to ensure the implementation of rectification measures to ensure that the workshop and warehouse fire separation, flammable and explosive dangerous goods warehouse, safe evacuation Facilities, indoor and outdoor fire hydrant systems, the laying of electrical wiring, electrical equipment installation, warehouse fire safety management, warehouse lighting and freight elevators set in line with fire safety technical regulations.
(4) Strengthen employee fire training. Enterprises should organize new posts and new posts for employees before the fire safety training, take a colorful, close to the actual form of the factory to carry out regular fire safety publicity and education, to enhance staff awareness of fire safety, basic fire safety knowledge And fire-fighting skills at the same time, actively guide employees from the actual shoe factory, serious thinking about the shoes fire safety measures, fire-fighting methods, and vigorously enhance the effectiveness of publicity and education training.
(5) organize fire drills. In accordance with the characteristics of the footwear industry, shoe factories in a timely manner to develop fire and emergency evacuation plans to the backbone of the team, security personnel composed of voluntary fire brigade consisting mainly of a fire and emergency evacuation plans to organize a drill, through the inspection of fire fighting and organizational command, Alarm and alarm handling procedures, emergency evacuation, fire fighting and fire fighting and communication links, security protection and rescue procedures and measures, and constantly improve the fire fighting and emergency evacuation plans to enhance the psychological quality of employees and improve the resilience of enterprises to withstand fires.
Fourth, the footwear manufacturers fire design and selection of fire-fighting equipment
From the footwear industry's fire situation and fire rating requirements, we have a fire-fighting equipment in the selection of highly targeted, in order to really play a fire safety role. From the fire extinguishing agent point of view, to dry powder fire extinguishing agent is appropriate; from the fire efficiency point of view, with the fastest start, automatic fire extinguishing equipment fire extinguishing efficiency is appropriate; fine dry powder fire extinguishing agent and water mist, foam, carbon dioxide and other phases Than in the fire efficiency, fire area, the equivalent unit cost of fire far better than the latter three aspects. Its advantages include: its fire extinguishing efficiency, the use of a wide temperature range, no special requirements on the environment; installation, maintenance, simple and convenient; does not require external power, water, does not cause secondary disasters, easy to clean. At the same time, it also has the advantages of non-toxic, pollution-free, safe and so on. Can be said that the most suitable footwear industry fire fighting products.
Ultrafine powder and series of automatic fire extinguishing devices (systems), compared with other fire extinguishing devices, has the following main advantages:
1, excellent fire performance
Ultrafine powder efficient fire extinguishing agent identified by the national science and technology department, is a national initiative and won the national invention patent, currently leading the world's cutting-edge level, the fire extinguishing concentration of 100g / m3, extinguishing rate is 40 times the fire extinguishing agent series, the fire fighting efficiency is Ordinary ABC powder fire extinguishing agent 6-10 times, is 2-3 times of halon fire extinguishing agent, is 10-12 times of heptafluoropropane fire extinguishing agent.Applicable to military, civil facilities and all kinds of places to save. A, B, C, E Fire and Al-based fires whose price / performance ratio is incomparable with other fire-extinguishing products. Can reach 5-10 seconds fast extinguishing. This will effectively control the fire in the initial state, so as to avoid the fire extinguishing stage caused by the stage of development of the fire.
2, chemical inhibition
The combustion process is a chain reaction process. OH and H radicals are the key free radicals that maintain the combustion chain reaction. They have high energy, are very lively and have a short lifespan. Once they are generated, they immediately initiate the next reaction to generate more More free radicals, the combustion process to continue and continue to expand.
When the dry powder fire extinguishing agent is added to the combustion zone and mixed with the flame, the free radicals are instantaneously adsorbed on the surface of the powder when the dry powder contacts the free radicals in the flame, The reaction, with the aid of the powder, consumes free radicals OH and H in the combustion reaction. When a large amount of powder is sprayed into the flame in the form of a mist, a large amount of free radicals in the flame are adsorbed and converted, so that the number of free radicals is drastically reduced, causing the chain reaction of the combustion to be interrupted and eventually the flame is extinguished.
3, three kinds of start-up mode, to ensure effective start
Ultrafine powder series uses the most advanced and reliable temperature control, electronic control and superconducting three start-up methods, when the temperature reaches the set value, the temperature control system on the fire extinguishing device automatically opens, release of ultra-fine powder fire extinguishing agent , Quickly extinguish the fire. Under certain circumstances, when the fire extinguishing system needs to be rapidly extinguished and multiple starters are simultaneously activated, the superconducting induction line rapidly transmits a fire signal to the fire extinguishing apparatus and promptly discharges the ultra-fine dry powder extinguishing agent to extinguish the fire momentarily. In addition, the hanging automatic fire extinguishing device electronic control device can be connected with all the alarm controller, with signal feedback. Once the smoke, temperature detectors found a fire, the fire controller immediately start the command, the fire extinguishing device receives the signal automatically open the moment after the release of fire extinguishing agent.
4, easy to install and use
Easy maintenance, easy installation, small amount of work, without perforating the wall and a large number of pipelines and ancillary facilities.
As can be seen, the correct choice of fire safety products is the first step in security. Only the correct selection of safety fire products have a real sense of safety. Only in this way can life and property safety be protected in the true sense. National Anda produced by the company, "Extreme Anda" ultrafine powder can be said that the best choice for the fire fighting footwear industry in the footwear industry in the process of development for the escort!
But at the same time we also see the footwear industry currently exists fire hazard. Still remember the night of October 21, 2007, Putian City, Fujian Province, Shiyu Island Shitou Zhen Feida vamp factory suddenly caught fire, the raging fire eventually led to the tragedy of 37 people died, temporarily shocked the country.
