According to the introduction of the Zibo Municipal Government of Shandong Province on the morning of the 29th, a local chemical factory had a deflagration accident on the evening of the 28th. As of 11:00 this morning, three people were killed and eight others were injured. According to another report, a deflagration accident occurred in a workshop of Shandong Baoyuan Chemical Co., Ltd. in Tangshan Town, Huantai County, Zibo City, Shandong Province. Two people were killed on the spot, one was seriously injured and eight were slightly injured.
At 8:23 on the morning of the 27th, Shaanxi Bao Nitrogen Industry Group Co., Ltd. (formerly Baoji Nitrogen Fertilizer Plant) exploded, and a large group of black smoke was raised on the spot. The top of a tower-shaped device in the plant area was destroyed. Fortunately, there were no casualties. The cause of the accident was initially identified as a result of equipment being in disrepair and gas leakage.
Chemical plant explosions have occurred frequently in recent times. How can security facilities help to ensure life safety and protect people's property? The lessons of every accident are very painful. What can we do before the accident to achieve prevention? In the first place, 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.
From a technical point of view, security monitoring measures can be taken. For example, riot cameras can also be called high security cameras, anti-shock cameras, anti-strike cameras, and tamper-proof cameras. A camera that can still guarantee the normal operation of components under the attack of external violence. Its characteristic is that its outer casing has strong impact resistance and can cope with the harsh environment.
In general, chemical plant sites are large in scale, and production and management safety factors are high. The combination of on-site monitoring and production command and dispatching of many production workshops, semi-finished warehouses and other functional departments can greatly improve the intelligent management level of the factory.
A chemical enterprise, the production process is the most important, especially the production line, chemical reaction equipment, explosion-proof, fireproof, anti-corrosion area is a place for special monitoring and monitoring, using professional high-definition explosion-proof cameras with zoom lens clear monitoring and control, through The screen display can inform or direct the labor situation of the production workshop staff at any time. The enterprises with higher automation can reduce the staff and realize automatic control.
The management of finished products and raw materials warehouses of chemical enterprises has always plagued the security problems of enterprises, especially some flammable, explosive and perishable products. By installing surveillance and monitoring systems, it prevents the occurrence of unattended, unmanned products for a long time. In the above situation, the situation of inventory 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. In order to get timely and effective treatment, prevent the situation from further worsening.
According to industry experts, accidents in chemical companies must meet the conditions of temperature, concentration, and fire source. Because the industry is a high-risk industry, the protection measures are generally strict, and the accidents are controllable through some technical and procedural settings.
Making full use of security high-tech products is a weapon to remove security risks. At present, hazard source monitoring, video surveillance, tracking and positioning, disaster prevention early warning, emergency rescue technology and product input and application in security products can all be used in explosion-proof, anti-chemical, anti-radiation, anti-collapse, anti-traffic accidents, etc. To an important role. Such as safety production emergency monitoring and control system, the video surveillance system, intelligent automatic production monitoring equipment system can be organically integrated and data collection, to achieve monitoring of dangerous sources, dangerous goods and information data collection, to achieve automatic alarm and critical police treatment and Event reporting function.
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. However, the fire protection environment of chemical sites is complex, with the characteristics of difficult management and many monitoring systems. How to comprehensively apply and manage a variety of detectors, alarm systems and fire extinguishing equipment is the biggest difficulty at present. Through the fire remote monitoring system, the unified and effective management of various subsystems in the chemical industry can be realized. Through multi-level monitoring, the synergistic effect between the subsystems can be realized, and the phenomenon of false positives and false negatives generated during the operation of the single unit can be avoided. The management level and safety precaution coefficient of the chemical plant have been greatly improved.
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 frequent occurrence of chemical explosion accidents, the relevant national safety supervision departments should supervise and urge relevant enterprises to immediately launch “pull-net†safety inspections, vigorously promote the application of safety prevention technologies, improve the monitoring system of key hazard sources, and popularize safety prevention knowledge. We will do our utmost to avoid the recurrence of major and mega-security incidents to protect the lives and property of the people. |
