A flash explosion occurred in a thermal power plant in Dingyuan, Anhui Province, killing 6 people! How to avoid such an accident?
Flash explosion accident Flash explosion accident refers to that flammable and explosive gases gather to a certain concentration in a relatively closed space with no air circulation, and once they encounter an open flame or electric spark, they will immediately deflagrate and explode. Generally speaking, there will only be one explosion. If flammable and explosive gases can be supplemented, there will be many explosion accidents.
What are the characteristics of flash explosion? Flash explosion is sudden and dangerous. There are often no obvious signs before the incident. The whole reaction process is even less than 0. 1 second from the occurrence to the end, which does not give people time to react at all. The products produced and stored by chemical enterprises are mostly oil products, and most of them are volatile, with low flash point and ignition point. Long-term contact with air is easy to produce explosive mixed gas. In case of open fire or electric spark, it may explode first and then burn, or burn first and then explode, both of which are instantaneous, which will cause great harm to on-site personnel and rescuers. ?
How to avoid flashover at work? Strengthen risk identification and control measures
Fully understand the major safety risks of special operations such as entering confined space and hot work, and upgrade and manage all hazardous chemicals that constitute major hazard sources when hot work in tank farm and entering confined space. The person in charge must personally organize and strictly confirm the safety conditions of on-site operations to ensure the safety of operations. Strict implementation of the work permit approval system, comprehensive safety risk identification and analysis, strict scientific detection of flammable gas, toxic gas concentration and oxygen content in confined spaces, practical implementation of various preventive measures, and strengthening the whole process monitoring.
Strengthen the safety management of the change process.
Relevant enterprises should establish, improve and strictly implement the change management system according to the requirements of chemical process management elements, and comprehensively identify and control the risks brought by various changes. When the process, equipment, materials, chemicals, public works, production organizations, personnel and contractors change, the enterprise should be included in the change management, and analyze the possible new safety risks, take measures to eliminate and control the safety risks, and modify the relevant operating procedures or construction plans in time. Before implementing the change, the enterprise shall organize professionals to conduct audit and confirmation inspection to ensure that the change has safety conditions.
Do a good job in safety production in summer flood season
High temperature, high humidity, heavy rain and lightning occur frequently in summer. All regions and related chemical and hazardous chemicals enterprises should attach great importance to it, strengthen the prediction and early warning of disastrous weather and natural disasters, formulate effective preventive measures in advance, and conscientiously do a good job in the safety production of hazardous chemicals enterprises in summer and flood season. Since the second quarter, some enterprises have a strong desire to catch up with the construction period and output. In addition, the efficiency of the chemical market continued to improve this year. Once they relax their mentality and lower their requirements, they are prone to accidents. It is necessary to urge enterprises to carry out in-depth safety risk identification, control and hidden danger investigation and management according to the characteristics of safety production in summer flood season, strengthen daily safety management and ensure safety production.
