Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of production safety management, and in particular to a new operation safety management method based on operation safety analysis. Background Art
[0002] JSA, which stands for Job Safety Analysis, is a widely used risk assessment tool in the field of safety management. It plays a vital role in the operation process. It is used to identify and control potential hazards in the operation process and provide strong support for safety management.
[0003] At present, the existing job safety management method includes a job task module and a JSA analysis module, wherein the job task module is used to display the job task creation template to the user, realize the creation of the job task, receive the approval result of the job task, and send the approved job task to the JSA analysis module; the JSA analysis module is used to receive the job task that has passed the job task approval, and display the JSA analysis module to the user according to the user's instructions, so that the user can perform JSA analysis on the selected job task on the JSA analysis module to generate a JSA analysis form.
[0004] However, these measures currently adopted contain at least the following three problems: 1) Highly subjective: The existing operation safety management method, when conducting risk analysis on each operation activity, confirms the possible accident type of each operation activity from the preset accident types, and determines the severity, possibility and risk level of the possible accident type. However, different personnel may have different opinions when determining the accident type of the same operation activity. Everyone has his or her own opinion, which is highly subjective. 2) Low management efficiency: When analyzing a work activity, the existing work safety management method needs to first receive the approved work tasks through the work task module, and then perform JSA analysis on the approved work tasks. The JSA analysis includes first decomposing into work steps and work activities in sequence, and then analyzing the work activities. Therefore, this work safety management method is cumbersome and inefficient; 3) The risk level classification is not clear. The existing operation safety management method automatically divides the overall risk level of the operation, lacks a clear risk operation level classification standard, and cannot accurately and effectively identify operation risks. Summary of the invention
[0005] In response to the above three problems, the purpose of the present invention is to propose a new job safety management method based on job safety analysis. By using the JSA tool to compile job tables and using the LEC risk assessment method to score the risk of each work step in the job activity process, the subjectivity in job safety management is reduced. At the same time, the risk levels are clearly divided, which helps safety managers to more effectively identify and control job risks and improve the efficiency and effectiveness of safety management.
[0006] This is achieved through the following technical solutions: A new method for job safety management based on job safety analysis, the method comprises the following steps: S1, using the JSA tool to compile a job table, including: classifying job activities, decomposing the job activity process into multiple work steps, identifying the hazard factors existing in each work step, and evaluating the impact caused by the hazard factors and the risk analysis of the consequences; S2, using the LEC risk assessment method to score the risk of each work step in the job activity process, where "L" represents the possibility, "E" represents the exposure frequency, and "C" represents the severity of the consequences. Different scores are used to represent the possibility, exposure frequency and severity of the hazard events occurring in each work step in the job activity process, and then The risk factor of each work step is calculated according to the formula D=L×E×C; S3. The risk factor of each work step is calculated according to the LEC risk assessment method, and the risk factor is divided into four levels: risk factors of 1-9 are divided into low risk, risk factors of 10-29 are divided into medium risk, risk factors of 30-49 are divided into high risk and risk factors ≥50 are divided into extremely high risk; S4. According to the risk factor level, each work step in the operation process is divided into two types of violation levels: general violation and serious violation, among which low risk and medium risk are judged as general violation, and high risk and extremely high risk are judged as serious violation; and according to the operation level, formulate and implement corresponding safety measures.
[0007] The present invention uses the LEC risk assessment method to score the potential hazards in the operational process and clearly divides the risk levels according to the risk scores, thereby reducing the subjectivity in operational safety management, enhancing the practicability and operability of operational safety analysis, and improving the efficiency and effectiveness of safety management.
[0008] Preferably, in step S1, classifying the operation activities includes: classifying according to the nature and type of the operation, classifying according to the environmental conditions of the operation, and classifying according to the equipment and tools used in the operation; wherein, the classification by nature and type at least includes: production operation, maintenance operation and loading and unloading operation, the classification by the environmental conditions of the operation at least includes: indoor operation, outdoor operation and high temperature operation, and the classification by the equipment and tools used in the operation at least includes: mechanical equipment operation and electrical equipment operation. By classifying the operation activities, different types of operation risks can be better understood and managed, and the efficiency of operation safety management can be improved.
[0009] Preferably, in step S1, the hazard factors include: physical hazards, biological hazards, ergonomic hazards and psychological and physiological hazards. By describing each hazard factor in detail and evaluating the severity of the impact and consequences that each hazard factor may cause, it is convenient to provide a basis for subsequent risk assessment and control.
[0010] Preferably, in step S2, the scoring criteria for possibility include: 1-2 points for possible occurrence, 3-4 points for very likely occurrence, and 5-10 points for frequent occurrence; the scoring criteria for exposure frequency include: 1-2 points for weekly exposure, 3-5 points for daily exposure, and 6-10 points for continuous exposure; the scoring criteria for severity of consequence include: 1-2 points for minor, 3-4 points for moderate, 5-9 points for severe, and 10-15 points for catastrophic. By finely dividing the scoring criteria for risk scoring, it is helpful for safety managers to effectively identify and control operational risks.
[0011] Preferably, in step S4, the safety measures for low-risk operations include: training operators on safety knowledge and providing operation manuals, setting up warning signs on site and conducting regular inspections, and warning or deducting points and fining violators. By formulating corresponding safety measures for low-risk operations, it is helpful for operators to become familiar with the operation steps and potential dangers, and understand how to avoid potential dangers in each operation step, thereby improving operators' understanding of the correct approach to each operation step and enriching operators' safety knowledge.
[0012] Preferably, in step S4, the safety measures for medium-risk operations include: in-depth safety knowledge training and skills training for operators, setting up warning signs and frequent inspections on site, and recording or suspending and fining violators. By formulating corresponding safety measures for medium-risk operations, operators can understand accidents and causes that have occurred in similar operations, thereby improving their risk awareness.
[0013] Preferably, in step S4, the safety measures for high-risk operations include: conducting special training and assessment for operators, setting up special personnel to monitor and strictly control the site, and suspending, fining, demoting or dismissing violators. By formulating corresponding safety measures for high-risk operations, operators can be equipped with rich safety knowledge and experience, while reducing the occurrence of dangerous accidents in the operation area.
[0014] Preferably, in step S4, the safety measures for extremely high-risk operations include: in-depth training of operators and repeated assessments and drills, strict on-site control measures and review and evaluation of operation plans, and immediate dismissal, heavy fines or criminal liability for violations. By formulating corresponding safety measures for extremely high-risk operations, the safety awareness and operating skills of operators are strengthened, ensuring the safety of the working environment.
[0015] Compared with the prior art, the present invention has the following beneficial effects: The technical solution of the present invention provides a standard risk assessment and violation operation level judgment process by using the JSA tool to compile the operation table and utilizing the LEC risk assessment method to perform risk scoring on each work step in the operation process, thereby reducing the subjectivity in operation safety management and clearly dividing the risk levels, which helps safety management personnel to more effectively identify and control operation risks, enhances the practicability and operability of operation safety analysis, and improves the efficiency and effectiveness of safety management. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 The flowchart of a new job safety management method based on job safety analysis is shown in the figure. DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0018] like Figure 1As shown in the figure, it is a flow chart of a new type of job safety management method based on job safety analysis. First, the JSA tool is used to compile the job table, including: classifying the job activities, decomposing the job activity process into multiple work steps, identifying the hazard factors in each work step, and evaluating the impact and consequence risk analysis caused by the hazard factors; then the LEC risk assessment method is used to score the risk of each work step in the job activity process, and different scores are used to represent the possibility, exposure frequency and consequence severity of the hazard incidents in each work step in the job activity process, and then the risk coefficient of each work step is calculated according to the formula; then, according to the risk coefficient of each work step calculated by the LEC risk assessment method, the risk coefficient is divided into four levels; according to the risk coefficient level, each work step in the job activity process is divided into two types of violation levels: general violation and serious violation, and according to the job level, the corresponding safety measures are formulated and implemented.
[0019] The method specifically comprises the following steps: S1. Use the JSA tool to compile a worksheet. The workflow is as follows: first classify the work activities; then decompose the work process into multiple work steps according to the order of the work steps; then identify the hazard factors in each work step, and describe in detail the source, nature, transmission path, and impact on the human body and the environment of each hazard factor. Among them, hazard factors include: physical hazards, biological hazards, ergonomic hazards, and psychological and physiological hazards; finally, identify the impact on the health and safety of workers, damage to equipment and facilities, impact on production progress and quality, and pollution to the environment after the hazard event occurs, and comprehensively consider historical data, industry experience, expert opinions, and the environment of the work site to determine the probability of the occurrence of the hazard event. At the same time, evaluate the severity of the consequences of the hazard event from the degree of casualties, the size of property losses, the degree of environmental damage, and the size of the social impact. Classification of operational activities includes: classification based on the nature and type of the operation, classification based on the environmental conditions of the operation, and classification based on the equipment and tools used in the operation; specifically, classification based on the nature and type of the operation includes at least: production operation, maintenance operation, and loading and unloading operation, classification based on the environmental conditions of the operation includes at least: indoor operation, outdoor operation, and high-temperature operation, and classification based on the equipment and tools used in the operation includes at least: mechanical equipment operation and electrical equipment operation.
[0020] In this embodiment, when using the JSA tool to compile a work sheet, the work activities are first classified. The classification of work activities can better understand and manage different types of work risks and improve the efficiency of work safety management; after the work activities are classified, the work activity process is decomposed into multiple work steps to ensure a comprehensive understanding of the work activities. At the same time, when the hazard factors are described in detail later, the hazard factors can be analyzed and described in more detail and accurately; after the work activities are decomposed, the hazard factors existing in each work step are identified, and the hazard factors are described in detail; finally, when evaluating the impact and consequence risk analysis caused by the hazard factors, the severity of the impact and consequences that may be caused by the hazard factors can be quickly evaluated through the detailed description of the hazard factors, providing a basis for subsequent risk assessment and control.
[0021] In this embodiment, JSA, which stands for Job Safety Analysis, is a widely used risk assessment tool for identifying and controlling potential hazards in the operation process. Through the JSA tool, safety managers can analyze each step in the operation process in detail to ensure a comprehensive understanding of the operation, describe the hazard factors in each step, identify possible risks, and then conduct risk analysis on the impact and consequences caused by the hazard factors to assess the severity of the consequences of potential hazards.
[0022] S2. Use the LEC risk assessment method to score the risk of each work step in the operation process, where "L" stands for possibility, which refers to the probability of a hazardous event, "E" stands for exposure frequency, which refers to the frequency of exposure of workers to hazardous environments, and "C" stands for severity of consequences, which measures the severity of the consequences that may be caused after a hazardous event occurs. Then different scores are used to represent the possibility, exposure frequency and severity of consequences of hazardous events occurring in each work step during the operation process. Among them, the scoring criteria for risk scoring are: the scoring criteria for possibility include: 1-2 points for possible occurrence, 3-4 points for very likely occurrence and 5-10 points for frequent occurrence; the scoring criteria for exposure frequency include: 1-2 points for weekly exposure, 3-5 points for daily exposure and 6-10 points for continuous exposure; the scoring criteria for severity of consequences include: 1-2 points for mild, 3-4 points for moderate, 5-9 points for severe and 10-15 points for catastrophic. After obtaining the scores corresponding to the possibility, exposure frequency and severity of consequences of hazardous events occurring in each work step through the LEC risk assessment method, the corresponding risk coefficient of each work step is calculated according to the formula D=L×E×C.
[0023] In this embodiment, the LEC risk assessment method is used to assess the dangers and hazards of operators when they are working in a potentially dangerous environment. The present invention uses the LEC risk assessment method to score the risk of each work step in the operation process, assess the risk coefficient of each work step, and judge the level of illegal operations based on the risk coefficient, providing a standardized basis for operation safety management and improving the efficiency and effectiveness of operation safety management.
[0024] S3. According to the corresponding risk coefficient of each work step calculated by the LEC risk assessment method, the risk coefficient is divided into four levels: low risk, medium risk, high risk and extremely high risk. Specifically, the standard for risk factor classification is: after the safety management personnel analyze the probability of hazardous events in the operation activities, the frequency of exposure of operators to hazardous environments and the severity of the consequences after the hazardous events occur, they score them according to the LEC risk assessment method, and then calculate the corresponding scores according to the formula D=L×E×C to obtain the risk coefficient of the hazardous event, and then classify them according to the calculated risk coefficient. The risk coefficient is 1-9 for low risk, 10-29 for medium risk, 30-49 for high risk and ≥50 for extremely high risk.
[0025] S4. According to the risk factor level, each work step in the operation process is divided into two types of violation levels: general violation and serious violation. Among them, low risk and medium risk are judged as general violation, and high risk and extremely high risk are judged as serious violation; and according to the operation level, corresponding safety measures are formulated and implemented. Safety measures for low-risk operations include: regular safety knowledge training for operators and providing operation manuals for operators to consult at any time, as well as setting up basic warning signs on site to remind operators to pay attention to potential dangers, and arranging safety management personnel to conduct regular inspections. At the same time, warnings are given to personnel with general violations. If the same operator commits similar violations again, a written warning may be given and a certain performance score may be deducted or a fine may be imposed. Safety measures for medium-risk operations include: targeted safety knowledge and skills training for operators, reducing operational risks caused by improper operation, strengthening the setting of on-site warning signs, increasing the inspection frequency of safety management personnel, facilitating timely discovery and correction of operators' violations and potential safety hazards. At the same time, operators who commit general violations will be given written warnings and recorded, and required to participate in additional safety training courses. For operators who violate the rules again, more performance points will be deducted, and related work tasks may be suspended, fined and centralized safety learning will be imposed. Safety measures for high-risk operations include: special training and assessment for operators, setting up special personnel to supervise and strictly control the site, restricting the entry of unrelated personnel, and immediately stopping related work tasks for operators who commit serious violations, and imposing fines and demotions. If a safety accident occurs due to serious violations, the operator may face legal liability and dismissal. Safety measures for extremely high-risk operations include: in-depth safety training, repeated assessments and drills for operators, strict control measures on site and strict review and evaluation of operation plans. Operators who commit serious violations will be immediately dismissed and held legally accountable. If a safety accident occurs, the operator will be subject to heavy fines or criminal liability.
[0026] In this embodiment, the safety management personnel formulate corresponding safety measures in terms of training and education, on-site management and punishment measures for the four levels of low risk, medium risk, high risk and extremely high risk to reduce the operation risk. The formulation and implementation of these safety measures reduce the occurrence of dangerous accidents in the operation area, strengthen the safety awareness and operation skills of the operators, and ensure the safety of the operation environment.
[0027] In summary, the present invention uses the JSA tool to compile the operation table and uses the LEC risk assessment method to score the risk of each work step in the operation process, providing a standard risk assessment and violation operation level judgment process, reducing the subjectivity in operation safety management, and clearly dividing the risk levels, which helps safety managers to more effectively identify and control operation risks, enhances the practicability and operability of operation safety analysis, improves the efficiency and effectiveness of safety management, and is significantly progressive.
[0028] The above embodiments are only for illustrating the technical idea of the present invention, and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
