Description

Technical Field

[0001] This invention relates to the field of laboratory safety risk assessment technology, and in particular to a method and system for safety assessment of physical and chemical laboratories. Background Technology

[0002] Physicochemical laboratories are widely used in various fields such as university scientific research, testing and inspection, pharmaceutical research and development, and industrial production. Their daily operation involves various hazardous chemicals, high-temperature and high-pressure equipment, special electrical devices, and complex experimental procedures. They pose multiple safety risks such as fire, explosion, poisoning, and corrosion, and are key targets for safety production and safety supervision.

[0003] Safety assessment, as a core component of safety risk management in physical and chemical laboratories, is a key means of identifying safety hazards, implementing control measures, and preventing safety accidents. As the national requirements for laboratory safety management continue to rise, higher demands are being placed on the standardization, accuracy, and full-process control capabilities of safety assessments in physical and chemical laboratories.

[0004] In the existing technology, the safety evaluation of physical and chemical laboratories mostly adopts an evaluation model based on human experience, which relies on the professional ability and subjective judgment of the evaluators. It lacks a standardized and quantifiable evaluation system, which is prone to problems such as biased evaluation results and incomplete identification of hidden dangers. Summary of the Invention

[0005] The purpose of this invention is to provide a method and system for safety evaluation in physical and chemical laboratories to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] As a further improvement to this technical solution: the laboratory safety evaluation basic information filing module includes a basic information collection submodule, an evaluation index system configuration submodule, and an index weight pre-configuration submodule.

[0009] As a further improvement to this technical solution: the compliance data and on-site verification and evidence collection module includes a data compliance review submodule, an on-site verification mobile input device, a verification result summary submodule, and a verification draft generation submodule.

[0010] As a further improvement to this technical solution: the multi-dimensional risk quantification and grading evaluation module includes a veto item determination submodule, a quantitative scoring calculation submodule, a risk level classification submodule, and a risk root cause analysis submodule.

[0011] As a further improvement to this technical solution: the quantitative scoring calculation submodule constructs an indicator judgment matrix based on the analytic hierarchy process (AHP), verifies the rationality of the indicator weights through consistency checks, and calculates the comprehensive score of the laboratory safety evaluation based on the verified valid weight values; the consistency check adopts the following formula: In the formula To determine the consistency ratio of the matrix, To determine the consistency index of a matrix, To determine the average random consistency index of the matrix, the comprehensive score is calculated using the following formula: In the formula The final score for the laboratory safety evaluation is calculated based on the overall score. This represents the total number of primary evaluation indicators. For the first The weight values ​​corresponding to the first-level evaluation indicators. For the first The actual score corresponding to each primary evaluation indicator.

[0012] As a further improvement to this technical solution: the veto item judgment submodule presets a veto item list and performs a pre-judgment process before the comprehensive score calculation. When the laboratory has any non-compliance item in the list, a high-risk level judgment is directly triggered, terminating the subsequent regular score calculation process. The risk level classification submodule performs a four-level risk level classification based on the comprehensive score calculation result, with corresponding score ranges of greater than or equal to 90 points, 75 to 89 points, 60 to 74 points, and less than 60 points, which correspond to four levels: low risk, general risk, relatively high risk, and high risk, respectively. The veto item is directly judged as high risk.

The invention is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0030] Please see Figure 1 In this embodiment of the invention, a physical and chemical laboratory safety evaluation system includes a laboratory safety evaluation basic information filing module, a compliance data and on-site verification and evidence collection module, a multi-dimensional risk quantification and grading evaluation module, an evaluation report generation and grading disposal module, a non-conformity rectification closed-loop verification module, and a periodic review and evaluation system iteration module.

[0031] Specifically, the Laboratory Safety Evaluation Basic Information Filing Module is used to complete the basic preparation and system construction before the evaluation; the Compliance Documentation and On-site Verification and Evidence Collection Module is used to complete the data collection and fact confirmation during the evaluation process; the Multi-dimensional Risk Quantification and Grading Evaluation Module is used to complete the quantitative judgment and risk grading of the laboratory safety status; the Evaluation Report Generation and Grading Disposal Module is used to complete the output of evaluation results and the issuance of disposal instructions; the Non-conformity Rectification Closed-Loop Verification Module is used to complete the full-process tracking and closed-loop management of problem rectification; and the Periodic Review and Evaluation System Iteration Module is used to complete the continuous optimization and long-term control of the evaluation system.

[0032] The laboratory safety assessment basic information filing module includes a basic information collection submodule, an evaluation indicator system configuration submodule, and an indicator weight pre-configuration submodule.

[0033] Specifically, the basic information collection submodule is used to input, store, and update all basic data of the laboratory, including core basic information such as laboratory qualification documents, personnel ledgers, hazardous chemical ledgers, instrument and equipment ledgers, safety management systems, emergency plans, and historical safety incident records, providing complete basic data support for subsequent safety assessments;

[0034] The evaluation index system configuration submodule is used to build a three-level quantitative evaluation system of primary, secondary and tertiary indicators, clarifying the scoring rules, compliance requirements and deduction standards for each indicator, covering all dimensions of evaluation scenarios such as hazardous chemical management, instrument and equipment safety, electrical explosion protection, fire emergency, personnel operation, environmental facilities, waste disposal and system construction;

[0035] The indicator weight pre-configuration submodule is used to assign weights to each evaluation indicator. It uses the analytic hierarchy process to allocate the initial weights and supports dynamic adjustment of the weight ratio based on the laboratory's risk characteristics, providing a calculation benchmark for subsequent quantitative scoring.

[0036] The compliance documentation and on-site verification and evidence collection module includes a documentation compliance review submodule, an on-site verification mobile data entry device, a verification result summary submodule, and a verification working paper generation submodule.

[0037] Specifically, the data compliance review submodule is used to check the completeness, standardization, and timeliness of laboratory records against the established evaluation indicator system, mark items with missing, non-standard, or non-compliant data, and form a list of non-compliant data review items;

[0038] The on-site verification mobile data entry device is a portable mobile terminal device used by evaluators to enter verification results in real time during the on-site verification process, upload on-site photos, videos and other evidence materials, and simultaneously sign to confirm the on-site verification situation, so as to realize the real-time entry and upload of on-site verification data and avoid the secondary entry error of offline records;

[0039] The verification results summary submodule is used to integrate the full results data of the compliance review of documents and on-site verification, and to uniformly collect non-conformities, evidence, and verification records to form a complete verification dataset, providing input data for subsequent risk quantification assessment;

[0040] The verification documentation generation submodule is used to automatically generate standardized on-site verification documentation based on the summarized verification data, clearly identifying the location of non-conformities, specific issues, and violated standard clauses, thus forming a traceable and verifiable formal verification document.

[0041] The multi-dimensional risk quantification and grading evaluation module includes a veto item determination submodule, a quantitative scoring calculation submodule, a risk level classification submodule, and a risk root cause analysis submodule.

[0042] Specifically, the veto item judgment submodule is used to perform pre-judgment of high-risk items, avoiding the problem that conventional scoring cannot cover major security risks;

[0043] The quantitative scoring calculation submodule is used to complete the quantitative scoring of laboratory safety evaluation. It uses a standardized algorithm to verify the rationality of indicator weights and calculate the comprehensive score, thereby achieving the standardization and quantification of safety evaluation and avoiding the subjective bias of human evaluation.

[0044] The risk level classification submodule is used to classify laboratory safety risks based on quantitative scoring results, clarify the control requirements for different risk levels, and provide a basis for subsequent graded disposal.

[0045] The risk root cause analysis submodule is used to trace and classify the root causes of all non-conformities found during the inspection, clarify the core reasons for the problems, provide targeted directions for subsequent rectification, and avoid only rectifying superficial problems.

[0046] The quantitative scoring calculation submodule constructs an indicator judgment matrix based on the analytic hierarchy process (AHP), verifies the rationality of indicator weights through consistency checks, and calculates the comprehensive score for the laboratory safety evaluation based on the verified valid weight values. The consistency check uses the following formula: In the formula To determine the consistency ratio of the matrix, To determine the consistency index of a matrix, To determine the average random consistency index of a matrix, the overall score is calculated using the following formula: In the formula The final score for the laboratory safety evaluation is calculated based on the overall score. This represents the total number of primary evaluation indicators. For the first The weight values ​​corresponding to the first-level evaluation indicators. For the first The actual score corresponding to each primary evaluation indicator;

[0047] Specifically, this submodule constructs an indicator judgment matrix based on the analytic hierarchy process, builds a relative importance judgment matrix for each pair of indicators through expert scoring, and then verifies the rationality of the matrix through a consistency check formula to ensure the logical consistency of indicator weight allocation and avoid subjective contradictions in weight allocation.

[0048] The consistency check formula is used to verify the consistency of the judgment matrix. When the CR value calculated by the formula is less than 0.1, the judgment matrix meets the consistency requirements, the corresponding indicator weight values ​​are valid, and can be used for subsequent comprehensive score calculation. When the CR value is greater than or equal to 0.1, the judgment matrix has a logical contradiction and needs to be readjusted until the consistency requirements are met.

[0049] The purpose of the comprehensive score calculation formula is to calculate the weighted score of the laboratory safety evaluation based on the verified effective indicator weights and the actual scores of each primary indicator, so as to obtain a standardized percentage evaluation result and make the safety status of different laboratories and different evaluation cycles comparable and quantifiable.

[0050] The veto item determination submodule has a pre-set list of veto items. Before the comprehensive score calculation, a preliminary determination process is performed. When a laboratory has any non-compliance item on the list, a high-risk level determination is directly triggered, terminating the subsequent regular score calculation process. The risk level classification submodule performs a four-level risk level classification based on the comprehensive score calculation results. The corresponding score ranges are greater than or equal to 90 points, 75 to 89 points, 60 to 74 points, and less than 60 points, which correspond to low risk, general risk, relatively high risk, and high risk, respectively. Items that trigger a veto item are directly determined to be high risk.

[0051] Specifically, the veto item judgment submodule has a pre-set list of veto items that covers major safety hazard scenarios in physical and chemical laboratories. These include scenarios such as failure to implement double-person, double-lock management for easily explosive and highly toxic hazardous chemicals, lack of effective safety emergency plans, unqualified special operation personnel, serious blockage of fire exits, and failure to rectify major safety hazards. Through the pre-judgment process, laboratories with major safety hazards are directly identified and directly judged as high-risk, without the need for subsequent routine scoring calculations, ensuring the priority identification and control of major safety hazards.

[0052] The risk level classification submodule completes the standardized classification of four risk levels through a clear scoring range, clarifies the scoring range corresponding to each level, achieves standardization of risk level judgment, avoids subjective bias of manual judgment, and clearly defines the direct judgment of the triggering veto item as high risk, so as to achieve dual judgment coverage of major hidden dangers and routine scoring.

[0053] The evaluation report generation and tiered handling module includes a standardized evaluation report generation submodule, a tiered handling instruction matching submodule, and a rectification responsibility binding submodule;

[0054] Specifically, the standardized evaluation report generation submodule is used to automatically generate a standardized formal safety evaluation report based on the risk assessment results. The report content covers basic evaluation information, evaluation scope and basis, indicator system, scoring results, risk level, non-conformity list, rectification suggestions, and control requirements. It supports custom editing and export to form a formal evaluation result document.

[0055] The graded disposal instruction matching submodule is used to automatically match the corresponding disposal requirements and control measures according to the laboratory's risk level, clarify the rectification requirements, control methods, and scope of work suspension for different risk levels, and achieve precise matching between risks and disposal measures;

[0056] The rectification responsibility binding submodule is used to clarify the corresponding person in charge of rectification, rectification requirements, and rectification deadline for each non-compliance item, so as to implement the rectification responsibility to specific entities and ensure that the rectification requirements are implementable and traceable.

[0057] The non-conformity rectification closed-loop verification module includes a rectification progress tracking sub-module, a rectification effect verification sub-module, and a rectification closed-loop archiving sub-module.

[0058] Specifically, the rectification progress tracking submodule is used to receive rectification plans and rectification progress reports submitted by laboratories, track the rectification progress of non-conformities throughout the process, issue early warnings for projects that have not been rectified by the deadline, and provide technical guidance for projects that are difficult to rectify, so as to ensure that the rectification progress meets the requirements.

[0059] The rectification effect verification submodule is used to conduct on-site verification after rectification is completed in the laboratory, to verify the rectification effect of each non-conformity item, to confirm whether the rectification meets the safety requirements, and to reissue rectification instructions for items that are not rectified in place until the rectification meets the standards.

[0060] The rectification closed-loop archiving submodule is used to implement closed-loop handling for non-conformities that have been rectified and met the standards. It archives all the information in the rectification plan, rectification progress data, and rectification review records in a unified manner to form a complete rectification closed-loop archive for future reference.

[0061] The periodic review and evaluation system iteration module includes a periodic review triggering submodule, an evaluation system update submodule, and a historical data archiving and querying submodule.

[0062] Specifically, the periodic review triggering submodule is used to automatically trigger special spot checks and annual comprehensive evaluation processes according to preset cycles, and automatically increase the review frequency for high-risk laboratories to ensure continuous control of laboratory safety risks;

[0063] The evaluation system update submodule is used to update the evaluation indicator system, weight assignment, scoring rules, and veto item list based on the latest laws and regulations, industry standards, newly added experimental projects and risk scenarios in the laboratory, and historical rectification status, so as to continuously optimize the evaluation system and adapt to the dynamic changes in laboratory safety management.

[0064] The historical data archiving and querying submodule is used to store the entire process of laboratory safety evaluation, including basic ledgers, verification drafts, evaluation reports, rectification materials, and review records. It supports multi-dimensional retrieval and traceability queries, providing data support for the long-term safety management of the laboratory.

[0066] S1. Basic information filing and evaluation system construction stage: Delineate the evaluation scope and core evaluation dimensions, collect and archive all basic data of the laboratory, build a three-level evaluation indicator system, and complete the assignment of indicator weights, setting of scoring rules and configuration of a list of veto items.

[0067] S2.

[0068] S3. In the risk quantification and grading evaluation stage, the pre-judgment of the veto item is first performed. If the veto item is not triggered, the rationality verification of the indicator weight is completed through consistency verification. Based on the verified and valid weight values, the comprehensive score of laboratory safety evaluation is calculated. The four-level risk level is divided according to the comprehensive score results. At the same time, the root cause tracing and classification of non-conformities are carried out.

[0069] S4.

The evaluation indicator system and weight assignments are updated, evaluation rules and scoring standards are adjusted, and full-cycle evaluation data is archived and multi-dimensional retrieval is supported.

[0073] The method of use and working principle of this invention are as follows:

[0074] Usage Method: First, the Laboratory Safety Evaluation Basic Information Filing Module completes the delineation of the evaluation scope, collection and archiving of basic laboratory data, and the establishment of a standardized evaluation system. Then, the Compliance Documentation and On-site Verification and Evidence Collection Module completes the compliance review of the ledger data and the full-area verification of the laboratory site, collects the verification results, and generates standardized verification drafts. Subsequently, the Multi-dimensional Risk Quantification and Grading Evaluation Module completes the preliminary judgment of major hidden dangers and the quantitative scoring and risk classification of the laboratory's safety status. Then, the Evaluation Report Generation and Graded Disposal Module generates a formal safety evaluation report, issues rectification and disposal instructions according to the risk level, and clarifies rectification responsibilities. Afterwards, the Non-compliance Rectification Closed-Loop Verification Module tracks the rectification progress, completes the rectification effect review, and completes closed-loop archiving. Finally, the Periodic Review and Evaluation System Iteration Module triggers the review process according to the preset cycle, synchronously updates the evaluation system, and completes full-cycle data archiving, forming a complete closed-loop process.
