See the security knowledge of access control locks from the fire of Jilin

We gradually learned that the lock on the factory door was one of the important reasons for the heavy casualties in this accident. As for the reasons for locking the door, it was said that it was to prevent employees from going to the toilet, and it was said that they were afraid of stealing things. However, it fundamentally reflects the weak awareness of corporate safety production and the indifference to employee rights. The current enterprises have more or less certain risks, and there is no 100% security. However, if accidents occur one after another, and there are factors such as “door locks and closed locks”, this is a factor that will increase the accident losses. It reflects the degree of awareness of the safety production of supervisors.

We have seen that many companies have anti-lock doors during production to prevent employees from going out privately. Most of them use conventional locks to lock the door. In the event of an emergency, this door becomes a "life-and-death door"! So, do we have more advanced locks that can solve the problem of opening a door in time when an emergency occurs? Many of our lock companies know that some access control locks can do it.

In fact, it is very simple, people with security awareness will think that if the fire door is equipped with an electromagnetic lock (magnetic lock), when the fire occurs, the electromagnetic lock is immediately opened after the power is cut off, thus achieving the effect of escape. We first understand the working principle of the electromagnetic lock: the design of the electromagnetic lock (or magnetic lock) is the same as that of the electromagnet. It uses the principle of electromagnetism. When the current passes through the silicon steel sheet, the electromagnetic lock will produce a strong suction tightness. Suction the suction iron plate to achieve the effect of locking the door. As long as the small current electromagnetic lock will generate a great magnetic force, the access control system that controls the electromagnetic lock power supply will be powered off after the correct identification personnel, and the electromagnetic lock will lose its suction to open the door. Because the electromagnetic lock has no complicated mechanical structure and the structure of the bolt, it is suitable for the passage control of the escape door or the fire door.

In this way, we have strengthened the level of corporate safety production prevention and avoided unnecessary casualties. Enterprises often say that hidden dangers are in the fire, prevention is better than disaster relief, and responsibility is more important than Taishan. But only when it is truly implemented, we will not see a regrettable security incident. Instead, we will apologize and review afterwards. Always mind.

The fire has already happened. What we have to do is to remember this disaster. We can't predict disasters, but we can make sure we are safe to escape when disaster strikes. At the same time, we also warned our company's responsible person, enterprises, units in the production and life process, can not only focus on economic benefits and anti-theft, but should also pay attention to fire safety work and escape from danger.

At the time of the accident, according to media interviews, Wang Xiaoyun, a 42-year-old packaging woman in the company, introduced that the company has three connected workshops, one is the slaughter workshop, the second workshop is the split packaging workshop, and the third workshop is the freezing workshop. "I can't see exactly where the fire started, just smelling a pungent smell." Wang Xiaoyun said, "The lights are gone, so everyone starts to run out along the previous working channel."

But when I arrived at the door, I found that the fire had blocked the door, so everyone ran to another exit. "We all ran out of the clothes of the people in front, and we were afraid that we could not climb if we fell." Feng Yan said.

According to other wounded people, some people used iron shovel to open and escape.

Agricultural industrialization enterprises, the most important production links, especially production lines, chemical reaction equipment, explosion-proof, fire-proof, anti-corrosion areas are more special monitoring and monitoring areas, using professional high-definition explosion-proof cameras with zoom lens clear monitoring and monitoring, Through the on-screen display, the labor situation of the production workshop staff can be notified or directed at any time, and enterprises with higher automation can reduce the staff and realize automatic control.

The management of the finished products and raw materials warehouses of enterprises has always plagued the security problems of enterprises, especially some flammable, explosive and perishable products. By installing a monitoring and monitoring system, it prevents products that have been left unattended for a long time and are unmanaged. In the above situation, the situation of stock products can be handled in the field, and the finished products and raw materials can be applied in time to install high-definition explosion-proof zoom cameras, and the products are clearly reflected to the supervision center, so that timely and effective treatment can be taken to prevent further deterioration of the situation.

Making full use of security high-tech products is a weapon to remove security risks

At present, hazard source monitoring, video surveillance, access control, tracking and positioning, disaster prevention early warning, emergency rescue technology and product input and application in security products, such as safety production emergency monitoring and control system, can video surveillance system, intelligent automated production The monitoring equipment system is organically integrated and data collected to achieve monitoring of dangerous sources, dangerous goods and information data collection, and to achieve automatic alarm and critical police processing and event reporting.

The detection of dangerous gases can be achieved by toxic and harmful gases and flammable and explosive gas detectors. Once the gas concentration reaches the explosion risk factor, the system will automatically issue an alarm. Through the fire remote monitoring system, the unified and effective management of the subsystems of the enterprise can be realized. The multi-level monitoring enables the synergistic effect between the subsystems to avoid the false alarms and false negatives generated during the single operation. Greatly improved management level and security factor. The required security is not only to prevent fire and explosion, but also to prevent the leakage of harmful gases and liquids, so as to be safe and environmentally friendly.

Preventing problems before they occur, increasing security supervision

In the production process of the enterprise, some harmful gases are also released, which seriously threatens the health of the staff and the residents nearby. How can security facilities be used to protect life and keep people's property? The lessons of every accident are very painful. What can we do before the accident, in order to prevent problems before they occur, it is essential to improve the application of security technology. In general, the causes of explosion accidents can be mainly attributed to two types: one is caused by criminal suspects; the other is due to illegal operations in the production process. However, no matter what causes the explosion and causes casualties, it will seriously endanger public safety.

Since the chemicals themselves and their combustion products are mostly highly toxic and corrosive, they are highly susceptible to poisoning, burns and environmental pollution. In the event of a fire or explosion accident of a dangerous chemical, if it is improperly disposed, it will not only effectively extinguish the fire, but will further expand the disaster. Therefore, in response to the explosion accident situation, the relevant national safety supervision departments should supervise and urge relevant enterprises to immediately launch a “pull-net” safety inspection, and vigorously promote the application of safety prevention technology, improve the monitoring system of key hazard sources, and popularize safety precautions. The best efforts are to avoid the recurrence of major and extraordinarily serious accidents to protect the lives and property of the people.
