Reflection on the electric welding accident in the chemical plant
" Materials for Reflection on an Electric Welding Accident in a chemical plant." I. Accident Review In the production and operation process of chemical plants, electric welding was a common operation, but once an electric welding accident occurred, it often brought serious consequences. A series of recent electric welding accidents, including the Henan factory's illegal electric welding caused a fire that killed 38 people, have sounded the alarm for us. In these accidents, the electric welding operation caused irreparable disasters due to illegal operations and inadequate safety measures. II. Cause Analysis of the Accident 1. human factor - Welder Skills and Qualification - Some welders had not undergone strict professional training and lacked in-depth understanding of the working principle, operating procedures, and potential dangers of electric welding. For example, in some accidents, if the welders were not familiar with the performance of the electric welding equipment, such as the influence of the adjustment of the voltage and current of the electric welding machine on the welding effect and safety, it might cause the welding process to be unstable and cause dangerous situations such as splashing sparks. - There was a phenomenon where welders operated independently without holding a safety operation certificate. This indicated that there were loopholes in the management of personnel, and the qualifications of personnel were not strictly controlled, causing unqualified personnel to enter the dangerous electric welding work environment. - safety awareness is weak - Many welders were not fully aware of the dangers of electric welding during the process. They may not strictly abide by safety regulations when operating. For example, in a flammable and explosive chemical plant environment, they did not realize that a small spark could cause a serious fire or even an explosion. For example, in the maintenance work of a chemical enterprise, there may be a large number of flammable and explosive chemicals around. If the welders did not take sufficient fire and explosion prevention measures during the operation and carried out the electric welding operation at will, it was easy to cause accidents. - The operator may have a fluke mentality during the work process, thinking that the accident would not happen to him, thus ignoring the safety operation procedures. For example, when conducting electric welding work in a space with poor ventilation, knowing that there may be a risk of gas accumulation causing an explosion, but still not taking effective ventilation measures. 2. Equipment and environmental factors - equipment management - The lack of regular inspection and maintenance of electric welding equipment was an important factor in the accident. During the long-term use of electric welding machines and other equipment, their circuits may be aged and damaged. If the welding wire was damaged, if it was not discovered and replaced in time, it might cause an electric shock accident or spark during the welding process, which could cause a fire. - Some chemical plants may have improper selection of electric welding equipment. In the special environment of the chemical industry, it is necessary to use electric welding equipment with special protective functions. If ordinary equipment is used, it may not meet the safety requirements. - environmental conditions - The environment of the chemical plant itself was highly dangerous, with a large number of flammable and explosive substances. If the surrounding environment was not effectively cleaned and protected during the electric welding operation, the high temperature and sparks generated by the electric welding could easily cause a fire or explosion. For example, if electric welding was carried out near a warehouse that stored chemical fluids, if the surrounding fluids were not isolated or removed, sparks could cause a fire. - Poor ventilation was also a problem that could not be ignored. When electric welding was carried out in some enclosed or semi-enclosed spaces, the smoke and harmful gases produced by the welding could not be discharged in time. Not only would it affect the health of the welders, but it was also easy to cause explosions in the presence of flammable gases. III. Protective measures and directions for improvement 1. personnel management - strengthen training - The chemical plant should establish a complete training system for welders, including theoretical knowledge and practical skills. The theoretical training should cover the working principle of electric welding, safety operation procedures, danger identification and prevention, etc. The practical operation training should allow the welders to operate in a simulated chemical environment and master the correct operation methods. - Regularly organize welders to undergo safety knowledge and skills re-training, and update their knowledge in time to adapt to the ever-changing safety requirements and new electric welding techniques. - qualification review - Strictly examine the qualifications of welders to ensure that every person engaged in electric welding operations has a legal and effective safety operation certificate. Set up qualification files for welders, and record the training records, test results, and operating experience of welders in detail for management and supervision. 2. Equipment and environmental management - Equipment maintenance and selection - A strict inspection and maintenance system for the electric welding equipment was formulated, and the equipment was checked regularly, including the wires, joints, pressure protectors, and other key components. Repair or replace the equipment in time to ensure that the equipment is in good operation. - According to the special environmental requirements of the chemical plant, select suitable electric welding equipment. For example, in areas with explosion-proof requirements, explosion-proof electric welding equipment should be used, and corresponding protective devices should be equipped, such as a shield that prevents sparks from splashing. - environmental security - Before the electric welding operation, a comprehensive safety assessment of the surrounding environment should be carried out, and the flammable and explosive materials around should be cleaned up. An effective fire and explosion-proof isolation zone should be set up. - To improve the ventilation conditions of the working environment and ensure that the smoke and harmful gases produced during the welding process can be discharged in time. For enclosed spaces with poor ventilation conditions, forced ventilation measures should be used, such as the installation of fans. Fourth, conclusion The occurrence of electric welding accidents in chemical plants is the result of a combination of many factors. We must reflect deeply on the personnel, equipment, environment and other aspects, and take effective preventive measures to avoid similar accidents from happening again. Only by attaching great importance to the safety management of electric welding operations, constantly improving the safety management system and operating specifications, and improving the safety awareness of all employees, can we guarantee the safety of production in the chemical plant, protect the safety of employees and the safety of the company's property.

Ancient Names of Weights and Weights
The name of weights and measures was first found in Shangshu·Yu Shu·Shun Dian. Through the study of ancient characters, it was found that the Chinese ancestors originally called "weights and measures" as "Liang Liang", and the pronunciation of the three was liang. Among them,"degree" represented the length of an object, which had already appeared in the oracle bone inscriptions. It was the model of "holding a ruler (measuring distance)". Humans first used the "body" to measure length, such as "steps" and other length units. The measurement of weight was called "Heng". In the ancient system of weights, there were units such as baht, liang, jin, jun, stone, etc. The first one baht was a medium-sized black millet grain. Ten grains were a burden, ten burdens were one baht, twenty-four baht was one liang, and sixteen liang was one jin (the situation in the Pre-Qin period).
