Such mutual influences may stem from various factors such as chemical reactions. Once not accurately monitored and evaluated, it may trigger a chain reaction and lead to the occurrence of safety accidents.
[0006] 2. With the continuous progress of science and technology and the rapid development of the chemical industry, new chemicals are constantly emerging, and the properties of existing chemicals may also change due to environmental changes or adjustments of operating conditions. However, the prior art seems unable to cope with these changes. They often lack sufficient flexibility and adaptability and cannot adjust adaptively according to the introduction of new chemicals or the changes in the properties of existing chemicals.

After linear normalization, the comprehensive risk assessment value between the two hazardous chemicals is calculated, and the calculation formula is as follows:

Description of the Drawings
[0044] Figure 1 It is a schematic structural diagram of the hazardous chemical safety information management system of the present invention. Detailed Embodiments
[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0046] Please refer to Figure 1 , the present invention provides a hazardous chemical safety information management system, including: a hazardous chemical information input module, a hazardous chemical risk assessment module, a hazardous chemical matrix analysis module, and a hazardous chemical management module; wherein,
[0047] The hazardous chemical information input module is used to input the basic information of hazardous chemicals, including basic information, physical properties, chemical properties, hazard classification, and first aid measures, in a structured manner;
[0048] The basic information includes ID (unique identifier), name, CAS number (Chemical Substance Registry Number), molecular formula, molecular weight, manufacturer, production date, expiration date, storage conditions, etc. The physical properties include state (solid, liquid, gas), color, odor, melting point, boiling point, density, solubility, etc. The chemical properties include reactivity, stability, flammability, explosion limit, oxidizing property, corrosiveness, etc. The hazard classification includes United Nations Hazardous Goods Number (UN number), hazard class (flammable, explosive, toxic, corrosive, etc.), health hazard, and environmental impact, etc. The first aid measures include emergency treatment methods in different situations such as skin contact, eye contact, inhalation, ingestion, fire extinguishing method, and leakage handling;
[0049] The structured data entry method defines a clear data structure, including field name, data type, data length, etc., ensuring that the data entered by different users is consistent in format and structure, thus reducing data errors and chaos caused by inconsistent formats;
[0050] The hazardous chemical risk assessment module calculates the combustion risk assessment value, explosion risk assessment value, and gas release risk assessment value after mixing any two of the entered hazardous chemicals based on the basic information of all the entered hazardous chemicals, and further calculates the comprehensive risk assessment value;
[0051] Obtain the basic information of all the entered hazardous chemicals, and detect the heat released by the mixture per unit time and the mass released per unit time when any two of the entered hazardous chemicals are mixed. "Per unit time" refers to per second (s). Through the heat released per unit time and the mass released per unit time, after dimensionless processing, the combustion risk assessment value is calculated. The calculation formula is as follows:
[0052]
[0053] Among them, Rv represents the combustion risk assessment value, Q t represents the heat released by the mixture per unit time, m t represents the mass released by the mixture per unit time, t represents the number of several unit times, t = 1, 2,..., T, and T is a positive integer;
[0054] It should be noted that when it comes to flammable chemicals, their own properties inherently contain potential combustion risks. Once these flammable chemicals generate a large amount of heat during the mixing process, then this risk will increase significantly. The generation of heat is often accompanied by chemical reactions, and in some cases, these reactions may be highly exothermic, that is, releasing a large amount of thermal energy. The rapid release of this energy may not only cause a sharp rise in the temperature of the mixture, but also trigger a chain reaction, thus forming combustion or even explosion.
[0055] Obtain the basic information of all the entered hazardous chemicals, and detect the explosion temperature and explosion pressure when any two of the hazardous chemicals are mixed and the mixture explodes. Through the explosion temperature and explosion pressure, after dimensionless processing, calculate the explosion risk assessment value. The calculation formula is as follows:
[0056]
[0057] Among them, Ev represents the explosion risk assessment value, and Et k represents the explosion temperature, and Ep k represents the explosion pressure, k represents the combination number of two hazardous chemicals, k = 1, 2,..., K, and K is a positive integer;
[0058] It should be noted that when two hazardous chemicals are mixed and the mixture does not produce an explosion reaction, the explosion risk assessment value is assigned 0. When the mixture produces an explosion reaction, the higher the explosion temperature and explosion pressure of the mixture, the higher the degree of explosion danger, and the higher the explosion risk assessment value. On the contrary, the lower the explosion temperature and explosion pressure of the mixture, the lower the degree of explosion danger, and the lower the explosion risk assessment value;
[0059] Based on the information in the safety data sheet (SDS) of chemicals or similar resources and the degree of harm that the toxicity of chemicals may cause to the human body, classify the toxicity of hazardous chemicals into five levels. Obtain the basic information of all the entered hazardous chemicals, and detect the toxicity, release concentration, and release speed of the gas released after mixing two chemicals. Through the toxicity, release concentration, and release speed of the gas released after mixing two chemicals, after dimensionless processing, calculate the gas release risk assessment value. The calculation formula is as follows:
[0060]
[0061] Among them, Tv represents the gas release risk assessment value, Tf represents the toxicity level of the released gas, Cfi represents the release concentration, Rfi represents the release speed, and i represents the number of the gas release time, i = 1, 2,..., M, and M is a positive integer;
[0062] It should be noted that during the processing of chemicals, when chemicals are mixed, reactions may occur and toxic gases may be released. Such reactions may occur quietly, but their potential poisoning risks cannot be ignored. The released toxic gases may not only directly harm the health of operators but also pollute the surrounding environment. Therefore, by detecting the toxicity, release concentration, and release speed of the gas released after mixing two chemicals, evaluate the toxicity risk of the released gas;
[0063] Obtain the combustion risk assessment values, explosion risk assessment values, and gas release risk assessment values of any two of all the entered hazardous chemicals, evaluate the risk of chemical reactions occurring between the two hazardous chemicals, and after linear normalization processing, calculate the comprehensive risk assessment value between the two hazardous chemicals. The calculation formula is as follows:
[0064] Cr = μ 1 *Rv + μ 2 *EV + μ 3 *Tv
[0065] Among them, Cr represents the comprehensive risk assessment value, Rv represents the combustion risk assessment value, Ev represents the explosion risk assessment value, Tv represents the gas release risk assessment value, and μ 1 、μ 2 and μ 3 represent the weight coefficients, 0 < μ 1 < 1, 0 < μ 2 < 1, 0 < μ 3 <1.
[0066] It should be noted that based on the basic information of all the entered hazardous chemicals, it is possible to comprehensively evaluate the risks that may arise from mixing any two hazardous chemicals, and calculate the combustion risk assessment value, explosion risk assessment value, and gas release risk assessment value. These assessment values provide intuitive risk information for operators;
[0067] By real-time evaluating the combustion, explosion, and gas release risks of the mixed chemicals, early warnings can be issued in advance, enabling operators and managers to take timely measures to prevent accidents. For high-risk chemical combinations, their mixed use can be automatically restricted, thus fundamentally reducing the likelihood of accidents.
[0068] The hazardous chemical matrix analysis module establishes a hazardous chemical risk assessment matrix A through the comprehensive risk assessment values between any two of all the entered hazardous chemicals, and calculates the weights of each hazardous chemical;
[0069] Obtain the comprehensive risk assessment values between any two of all the entered hazardous chemicals, and establish a hazardous chemical risk assessment matrix A through the comprehensive risk assessment values between the two hazardous chemicals:
[0070]
[0071] Among them, a mn represents the comprehensive risk assessment value between the mth hazardous chemical and the nth hazardous chemical. m is the number of rows of matrix A, and n is the number of columns of matrix A;
[0072] Calculate the weights of each hazardous chemical through the hazardous chemical risk assessment matrix A. The calculation formula is as follows:
[0073]
[0074] Among them, ω m represents the weight of each hazardous chemical. j is a positive integer, 0 < j ≤ N, and N is the total number of columns of the matrix;
[0075] It should be noted that all chemicals are listed at the top of the matrix, and then the same chemicals are also listed on the left. In this way, each chemical will cross with other chemicals in the matrix. For any two hazardous chemicals, make a pairwise comparison, evaluate the comprehensive risk between them, and calculate the weights between each hazardous chemical accordingly. In addition, as new chemicals are introduced or the properties of existing chemicals change, the matrix should be updated regularly;
[0076] The hazardous chemical matrix analysis module comprehensively considers the interactions between hazardous chemicals. Through the comprehensive risk assessment value, it can more accurately evaluate the risks of hazardous chemicals, calculate the weights of each hazardous chemical, which helps to identify high-risk chemicals and key risk points, so as to carry out targeted management and control.
[0077] The hazardous chemical management module determines the comprehensive risk assessment value and the weight of the hazardous chemicals during transportation or storage through the hazardous chemical risk assessment matrix, calculates the risk assessment index, compares the risk assessment index with the risk threshold, and takes corresponding measures according to the comparison results.
[0078] During transportation or storage, obtain the list of hazardous chemicals to be transported or stored. Through the hazardous chemical risk assessment matrix, determine the comprehensive risk assessment value and the corresponding weights between the hazardous chemicals to be transported or stored. Through the comprehensive risk assessment value and the corresponding weights, calculate the risk assessment index. The calculation formula is as follows:
[0079]
[0080] Among them, Ra represents the risk assessment index, and Cr s represents the comprehensive risk assessment value between the s-th group of hazardous chemicals, respectively represent the weights corresponding to different hazardous chemicals in the s-th group of hazardous chemicals. s = 1, 2,..., S, and S is a positive integer;
[0081] Preset the risk threshold, compare the risk assessment index with the risk threshold, and take corresponding measures according to the comparison results. Specifically, it includes:
[0082] When the risk assessment index is less than the risk threshold, it indicates that the risk of the currently transported or stored hazardous chemicals is within an acceptable range, and normal transportation or storage operations can continue;
[0083] When the risk assessment index is greater than or equal to the risk threshold, it indicates that there is a relatively high risk for the currently transported or stored hazardous chemicals, and further measures need to be taken to reduce the risk. An early warning is automatically issued, and the comprehensive risk assessment values of the transported or stored hazardous chemicals are sorted. The hazardous chemical with the highest comprehensive risk assessment value is removed until the risk assessment index is less than the risk threshold.
[0084] It should be noted that during the operation of transporting or storing hazardous chemicals, to ensure the safety of the operation process, for all the entered hazardous chemicals, strict sorting is carried out based on their comprehensive risk assessment values. To minimize potential risks, the hazardous chemical with the highest comprehensive risk assessment value is removed from the original combination and transported or stored separately;
[0085] According to the risk assessment index, high-risk chemical combinations can be identified, thus avoiding their transportation or storage in the same batch. By dealing with high-risk chemicals separately, potential accident risks can be reduced, and the overall safety level can be improved. When the risk assessment index exceeds the preset risk threshold, an early warning is automatically issued to remind relevant personnel to take corresponding preventive measures, which helps to detect potential safety hazards in advance, avoid the occurrence of accidents, and reduce the losses caused by accidents.
