Description

Technical Field

[0002] Hazardous chemicals refer to the abbreviated name of dangerous chemicals, which refer to chemicals with dangerous characteristics such as flammability, explosiveness, toxicity, corrosion, and radioactivity during the processes of production, storage, transportation, and use. When improperly managed or operated, they may cause significant harm to human health, the environment, and property. Therefore, the management and use of hazardous chemicals require special attention and must comply with relevant safety regulations and standards. In a laboratory, the use of hazardous chemicals is inevitable because many experiments require chemical reagents and raw materials. However, since a laboratory is usually a small environment with relatively compact equipment and facilities, the management and use of hazardous chemicals are particularly important.

[0063] This embodiment provides a hazardous chemical usage management method for a laboratory, as Figure 1 shown, including:

[0064] Step 1: Decompose the current experimental project in the laboratory to obtain a material requirement plan corresponding to each experimental process, and search for the material data corresponding to each hazardous chemical in the MSDS respectively;

[0065] Step 2: Determine the usage amount and usage time period corresponding to each hazardous chemical according to the material requirement plan and the material data, and construct the hazardous chemical management rules for the laboratory;

[0066] Step 3: Use the hazardous chemical management rules to conduct real-time supervision and management of the current experimental project, and take inventory of the real-time remaining amount corresponding to each hazardous chemical after completing the previous experimental project;

[0067] Step 4: Locate the target hazardous chemical with abnormal real-time remaining amount, restrict the use of the target hazardous chemical by the experimental personnel and give an alarm in the laboratory.

[0068] In this example, the current experimental project refers to the experimental project currently being carried out in the laboratory;

[0069] In this example, the experimental process refers to the process that needs to be executed for the current experimental project;

[0070] In this example, MSDS refers to the Material Safety Data Sheet, which contains various important data about hazardous chemicals;

[0073] In this example, the hazardous chemical management rules represent the rules that need to be followed when picking up and using hazardous chemicals in the laboratory;

[0074] In this example, the target hazardous chemicals refer to the hazardous chemicals with insufficient remaining quantity and unable to continue to support the smooth progress of the current experimental project.

[0075] The working principle and beneficial effects of the above technical solution: Since different experimental projects use different materials, before the experimenter conducts the current experimental project, the process is decomposed first to determine the material requirements plan corresponding to each experimental process, and the material data of each hazardous chemical is searched to facilitate the subsequent management of the usage amount of hazardous chemicals. Then, based on the material requirements plan and material data, the usage amount and usage time period of each hazardous chemical are deduced, and the corresponding hazardous chemical management rules are constructed, so as to conduct real-time supervision and management of the experimenter's operations. By analyzing the real-time remaining quantity of different hazardous chemicals after completing the previous experimental project, it is judged whether the hazardous chemicals in the laboratory can meet the current experimental project and corresponding alarm reminders are given. In this way, the usage amount of hazardous chemicals in the laboratory can be predicted in advance, and the experimental process can be supervised to avoid insufficient or excessive usage of hazardous chemicals, effectively improving the safety level of the laboratory, reducing laboratory accidents caused by inaccurate usage, and ensuring the smooth progress of the experimental project.

[0079] Temporarily store the expired laboratory materials for scrapping, and restrict the experimenter from using the expired laboratory materials.

[0080] In this example, the specified period is 14 days.

[0081] The working principle and beneficial effects of the above technical solution: Since expired hazardous chemicals are more dangerous, it is necessary to regularly check the expiration date of the materials in the laboratory and dispose of the expired laboratory materials. To further avoid accidents, restrict the experimenter from using the expired laboratory materials, and ensure the personal safety of the experimenter.

[0082] Example 3

[0083] Based on Example 1, for the method of managing the usage amount of hazardous chemicals in a laboratory, Step 1 includes:

[0084] Step 11: Structurally decompose the current experimental project to obtain a number of sub - project elements, construct an element logic tree for the current experimental project according to the element relationships between different sub - project elements, identify a number of tree branches included in the element logic tree, and construct the experimental process of the current experimental project according to the tree branches;

[0085] Step 12: Construct the process progress corresponding to each experimental process respectively, assign corresponding element operation attributes to the corresponding sub - project elements in the process progress, screen the first sub - project elements belonging to the material attribute, and screen the first sub - project elements belonging to the operation attribute, and construct a material requirement plan corresponding to the experimental process according to the first sub - project elements and the second sub - project elements;

[0086] Step 13: Obtain the MSDS of the laboratory, search for each of the first sub - project elements in the MSDS respectively, determine several types of hazardous chemicals used in each experimental process according to the search results, and conduct a deep search for each hazardous chemical in the MSDS to obtain the material data corresponding to each hazardous chemical.

[0087] In this example, the sub - project element represents an element required for the process of a project included in the current experimental project, including: materials, experimental operations, etc.;

[0088] In this example, the element logic tree represents a logic tree constructed according to the element relationships between different sub - project elements;

[0090] In this example, the process progress represents the progress required to complete an experimental process;

[0091] In this example, the element operation attribute represents the operation that a sub - project element needs to perform;

[0092] In this example, the material attribute indicates that the sub - project element belongs to laboratory materials, and the operation attribute indicates that the sub - project element belongs to experimental operations.

[0093] Working principle and beneficial effects of the above technical solution: In order to better supervise the experimental process, first divide the current experimental item into several sub-item elements, then analyze the logical relationships between different sub-item elements to construct an element logic tree, and then determine the experimental process of the current experimental item according to the tree branches included in the element logic tree. Furthermore, assign corresponding attributes to each sub-item element according to the process progress of the experimental process, construct a material requirement plan for the experimental process, and lay a foundation for subsequent material management. Then, search for each sub-item element in the MSDS of the laboratory, determine several hazardous chemicals required for this experimental process, and at the same time conduct a deep search for the hazardous chemicals in the MSDS to determine the material data of each hazardous chemical. In this way, comprehensive supervision can be carried out on the hazardous chemicals to ensure the smooth progress of the experiment and the personal safety of the experimental personnel.

[0094] Example 4

[0095] On the basis of Example 3, the method for managing the dosage of hazardous chemicals for a laboratory constructs a material requirement plan corresponding to the experimental process according to the first sub-item element and the second sub-item element, including:

[0096] Perform a first mark on each of the first sub-item elements respectively in the process progress, and perform a second mark on each of the second sub-item elements respectively;

[0097] Determine several material usage processes corresponding to the experimental process according to the marking results, and identify the laboratory materials included in each material usage process;

[0098] Estimate the dosage of the corresponding laboratory materials according to the material usage processes, and generate a material requirement plan for the experimental process.

[0099] In this example, the first mark and the second mark represent the results of distinguishing and marking the first sub-item element and the second sub-item element in the process progress;

[0100] In this example, the material usage process represents the order and usage method of using different laboratory materials.

[0101] Working principle and beneficial effects of the above technical solution: By separately marking the first sub-item element and the second sub-item element in the process progress to determine the material usage processes of the experimental process, and then estimating the dosage of the laboratory materials included in each material usage process, a material requirement plan for the experimental process is generated. In this way, multiple first sub-item elements and second sub-item elements can be processed in a short time, and the laboratory materials used in different experimental processes are determined to improve the accuracy of subsequent dosage supervision.

[0102] Example 5

[0103] Based on Example 1, for the method for managing the usage amount of hazardous chemicals in a laboratory, in step 2, it includes:

[0104] Step 21: Construct a hazardous chemical calling process corresponding to each experimental process according to the material demand plan and the material data, and perform chronological adjustment on the hazardous chemical calling processes according to the process sequence of each experimental process in the current experimental project to generate the total hazardous chemical calling process of the current experimental project;

[0105] Step 22: Determine several calling times corresponding to each hazardous chemical and the calling amount corresponding to each calling time according to the material demand plan, map the calling amount corresponding to each hazardous chemical into the corresponding process time period in the total hazardous chemical calling process respectively, and adjust the usage amount of hazardous chemicals in the process time period;

[0106] Step 23: Determine the usage amount and usage time period corresponding to each hazardous chemical according to the adjusted total hazardous chemical calling process, create a hazardous chemical usage model for the laboratory, and run the hazardous chemical usage model to analyze the collision risk probability between different hazardous chemicals by using the corresponding material data;

[0107] Step 24: Adjust the process time period of the total hazardous chemical calling process according to the collision risk probability, and construct the hazardous chemical management rules for the laboratory according to the adjusted total hazardous chemical calling process.

[0108] In this example, the hazardous chemical calling process refers to the process that needs to be executed when taking different hazardous chemicals during an experimental process.

[0109] The working principle and beneficial effects of the above technical solution: Generate the total hazardous chemical calling process of the current experimental project by constructing the hazardous chemical calling process corresponding to each experimental process, then adjust the usage amount of hazardous chemicals in each time period in the total hazardous chemical calling process according to the material demand plan, and analyze the collision risk probability between different hazardous chemicals by creating a model, and then adjust the time period of the total hazardous chemical calling process, effectively avoiding the phenomenon of collision accidents when experimental personnel take different hazardous chemicals at the same time. Finally, construct the hazardous chemical management rules for the laboratory according to the adjusted total hazardous chemical calling process, and use this rule to supervise and manage the experimental process of experimental personnel, improving the safety of the laboratory.

[0113] Step 32: Determine the real-time use of hazardous chemicals by the experimental personnel based on the behavior valid information. After the completion of the previous experimental project, analyze the real-time usage amount corresponding to the real-time use of hazardous chemicals, determine the real-time remaining amount corresponding to each hazardous chemical, and display it.

[0114] In this example, the real-time experimental behavior refers to the behavior generated by the experimental personnel during the experiment in the laboratory;

[0115] In this example, the real-time standard behavior refers to the standard behavior that the experimental personnel should present at the current moment;

[0116] In this example, the behavior valid information refers to the behaviors that must be carried out for the execution of the current experimental project;

[0117] In this example, the real-time usage amount refers to the usage amount of various hazardous chemicals during the previous experimental project.

[0118] The working principle and beneficial effects of the above technical solution: By evaluating the real-time experimental behaviors of the experimental personnel using the hazardous chemical management rules to obtain the behavior valid information of the experimental personnel, the real-time use of hazardous chemicals by the experimental personnel is determined. When an experimental project is completed, the real-time remaining amount of each hazardous chemical is determined and displayed. On the one hand, it is convenient for the experimental personnel to understand the remaining amount of hazardous chemicals at any time, and on the other hand, it is convenient to judge whether the remaining amount of hazardous chemicals can meet the usage amount of the next experimental project.

[0119] Example 7

[0123] Construct violation remedial measures according to the violation consequences and transmit them to the display terminal of the laboratory for display, and at the same time transmit them to the warning terminal of the laboratory for warning.

[0124] In this example, the behavior hazardous chemicals refer to the hazardous chemicals affected by the experimental violation behavior.

[0125] The working principle and beneficial effects of the above technical solution: Using the hazardous chemical management rules to identify the experimental violation behaviors of experimental personnel, then conducting consequence analysis on the behavior hazardous chemicals of the experimental violation behaviors, and constructing corresponding remedial measures to remind the experimental personnel to handle the errors in time, avoid the expansion of the scope of danger, and at the same time use the warning method to remind all experimental personnel in the laboratory to pay attention to safety, effectively reducing the probability of dangerous accidents occurring in the laboratory.

[0126] Example 8

[0127] Based on Example 1, for the method for managing the usage amount of hazardous chemicals in a laboratory, step 4 includes:

[0128] Step 41: Determine several to-be-experimented hazardous chemicals for the current experimental project according to the material requirement plan, and the to-be-experimented usage amount corresponding to each to-be-experimented hazardous chemical;

[0129] Step 42: Screen the target hazardous chemicals whose real-time remaining amount is lower than the corresponding to-be-experimented usage amount, and search for the improper hazards corresponding to each target hazardous chemical in the MSDS;

[0130] Step 43: Construct a hazard reminder for the current experimental project according to the improper hazards, and restrict the experimental personnel from using the target hazardous chemicals for the current experimental project;

[0131] Step 44: Generate an alarm text according to the improper hazards and transmit it to the warning terminal in the laboratory for warning.

At the same time, to ensure the safety of experimental personnel, restrict the experimental personnel from using this target hazardous chemical, and at the same time give a warning reminder to avoid the experiment failing because it cannot continue halfway through.

Then, according to the material requirement plan and the material data, the usage amount and usage time period of each hazardous chemical are deduced, and the corresponding hazardous chemical management rules are constructed, so as to conduct real-time supervision and management of the operations of the experimenter.

[0158] The working principle and beneficial effects of the above technical solution: In order to better supervise the experimental process, first divide the current experimental item into several sub-project elements, then analyze the logical relationships between different sub-project elements to construct an element logic tree, and then determine the experimental process of the current experimental item according to the tree branches contained in the element logic tree. Furthermore, according to the process progress of the experimental process, assign corresponding attributes to each sub-project element to construct a material requirement plan for the experimental process, which serves as a basis for subsequent material management. Then, search for each sub-project element in the MSDS of the laboratory to determine several hazardous chemicals required for this experimental process. At the same time, conduct a deep search for the hazardous chemicals in the MSDS to determine the material data of each hazardous chemical. In this way, comprehensive supervision can be carried out for the hazardous chemicals to ensure the smooth progress of the experiment and the personal safety of the experimental personnel.
