Description

Technical Field

[0001] The present invention belongs to the field of occupational health evaluation of employing units, and specifically relates to a current status evaluation method, system and monitoring equipment for evaluating the level of exposure of employees of employing units. Background Art

[0002] With the acceleration of industrialization, many employers have various occupational hazards in their production environments, such as harmful chemicals, noise, dust, etc. Long-term exposure to these hazards will not only affect the health of workers, but may also lead to occupational diseases in severe cases. Therefore, how to effectively evaluate the occupational health status of employers and take timely control measures has become an important task to protect the health of workers and prevent and control occupational diseases.

[0003] At present, most of the existing occupational disease hazard assessment methods rely on traditional questionnaires and regular health examinations. Although these methods reflect the employer's occupational disease prevention and control work to a certain extent, they lack real-time monitoring and quantitative analysis of occupational disease hazard factors in the actual working environment, especially the lack of dynamic monitoring of the intensity and duration of exposure to hazard factors. Therefore, the existing technology cannot comprehensively and accurately assess the distribution of occupational disease hazard factors of employers and the impact of these factors on the health of workers.

[0004] In recent years, as the country pays more and more attention to the health rights and interests of workers, workers' health concepts have gradually changed from occupational disease treatment to occupational disease prevention. The current status evaluation of occupational disease hazard factors has become one of the important means to prevent occupational diseases. Through the current status evaluation, it is possible to accurately identify the occupational disease hazard factors in the working environment of the employer, clarify their degree of hazard, and evaluate the effectiveness of occupational disease protection facilities and management measures, thereby providing a scientific basis for the daily occupational disease prevention and control management of the employer, and providing data support for the health administrative supervision department to implement occupational health supervision.

[0005] However, at present, most of the current evaluation methods for occupational hazard factors in my country are still based on the checklist method, combined with on-site test results for evaluation. This method can usually only simply classify and summarize occupational hazard factors, and cannot accurately evaluate the occupational hazard risks of employers. Existing methods can often only reflect the employer's compliance with the current national laws and regulations and standards in terms of occupational hazard prevention and control, but cannot provide a comprehensive and dynamic evaluation, lacking real-time monitoring of risk factors and risk quantification.

[0006] Therefore, there is an urgent need for a new method that can comprehensively and dynamically evaluate the occupational disease hazard factors of employers. Summary of the invention

[0007] The purpose of the present invention is to address the deficiencies in the prior art and to provide a method, system and monitoring equipment for evaluating the current status of the occupational disease hazard level of employees of an employer by comprehensively evaluating the occupational disease hazard factors in the working environment through real-time monitoring and data analysis, quantifying the exposure level of employees, and timely judging their health risks, thereby providing a scientific basis for taking corresponding control measures.

Through real-time monitoring, data analysis and risk assessment, it effectively provides decision support for occupational health management for employers, helps to improve the working environment, protect the health of workers, and comply with relevant laws and regulations and standards for occupational disease prevention and control.

[0067] Embodiment 1: A current status evaluation method for evaluating the level of exposure of employees of an employer

[0068] A method for evaluating the current status of the level of exposure of employees of an employer comprises the following steps:

[0069] S1. Collect basic information of the employer: By analyzing the production and operation history of the employer and the existing occupational health survey data, understand the basic occupational health status of the employer; by analyzing the production and operation conditions of the employer and the above collected data, understand the distribution of occupational disease hazard factors of the employer;

[0070] The basic information of the employer collected in step S1 includes the following: the personnel composition and job responsibilities of the employer, the production equipment, production process and types of occupational hazard factors that may be involved of the employer, and the employer's past occupational disease prevention and control records; the employer's past occupational disease prevention and control records include employee health files, historical health monitoring results, and occupational disease incidence rates.

[0071] S2. Evaluate the employer's occupational disease hazard factor data: Use portable monitoring equipment equipped with high-precision sensors to monitor the intensity level of occupational disease hazard factors that employees are exposed to in real time in the employer's workplace to obtain initial data;

[0072] The real-time monitoring data in step S2 includes the following:

[0073] Real-time monitoring of the concentration of harmful chemicals in the air, including but not limited to toxic gases, dust, and noise;

[0074] Real-time monitoring of air temperature, humidity, and air pressure environmental parameters;

[0075] Real-time monitoring of workers’ physiological parameters such as body temperature, heart rate, and respiratory rate to assess the health risks of their working environment.

[0076] S3. Develop an evaluation plan for the current status of occupational disease hazard factors in employers:

[0077]

[0078] In the formula, C exposure is the level of occupational disease hazard factors that workers are exposed to; C actual is the concentration actually detected in the workplace to which workers are actually exposed during work; t actual is the time of exposure during work; C standard limit is the workplace exposure limit specified by the state;

[0079] The current situation evaluation scheme in step S3 includes the following contents:

[0080] According to the work characteristics of different positions, set different monitoring cycles and data collection frequencies;

[0081] In different production environments, different standard limits are used for comparison based on monitoring data;

[0082] Use charts and data analysis to show the time distribution and concentration levels of workers' exposure to occupational disease hazards.

[0083] S4. Result determination: If C exposure is less than 1, it means that the worker’s exposure level to the chemical substance is within an acceptable range;

[0084] When C exposure = 0.5, it means that the worker's exposure level to the chemical is half of the standard limit, indicating that the risk of worker exposure to the chemical is relatively low, but continuous monitoring is still required;

[0085] When C exposure is greater than 1, it means that the level of worker exposure to the chemical exceeds the standard limit, the risk is high, and measures need to be taken to reduce the exposure level. Improvement measures should be taken immediately to optimize the ventilation system in the workplace, provide personal protective equipment, or adjust work shifts to ensure the health and safety of workers.

[0086] Furthermore, when C exposure is less than 0.5, it means that the level of workers’ exposure to the chemical is very low and the risk is small, so regular monitoring is sufficient;

[0087] When C exposure is between 0.5 and 1, appropriate occupational health examinations should be conducted on workers, and the management and monitoring of the working environment should be strengthened.

[0088] Example 1.C 接触 <1 Example and calculation process and suggestions

[0089] Suppose a worker is exposed to another chemical during a work week.

[0090] The actual concentration of the chemical substance detected in the workplace C 实际 and t 实际 as follows:

[0091] Tuesday: C 实际1 =1mg / m 3 , contact time t 实际1 = 3 hours;

[0092] Thursday: C 实际2 =0.5mg / m 3 , contact time t 实际2 =2 hours

[0093] The national standard limit value of this chemical substance C standard limit value = 5mg / m 3

[0094] Calculation process:

[0095] First calculate

[0096] Tuesday: C 实际1 *t 实际1 =1mg / m 3 *3 hours = 3 mg / m 3

[0097] Thursday: C 实际2 *t 实际2=0.5mg / m 3 *2 hours = 1 mg hour / m 3

[0098] The product of the concentration of the chemical to which the workers were exposed on Tuesday and Thursday and the exposure time was calculated to obtain the exposure amount in each time period.

[0099]

[0100] Add the exposures on Tuesday and Thursday to get the worker's total exposure for the week, and then calculate

[0101] Since C contact = 0.1 < 1, it means that the level of workers' exposure to the chemical is far below the standard limit and the risk is low. However, it is still necessary to regularly monitor the concentration of chemical substances in the workplace to ensure the continued safety of the working environment.

[0102] Example 2.C 接触 =0.5 implementation examples and calculation process and suggestions

[0103] Suppose a worker in a factory is exposed to a chemical during a work week.

[0104] The actual concentration Cactual of the chemical substance detected in the workplace and the contact time tactual are as follows:

[0105] Monday: C 实际1 =2mg / m 3 , contact time t 实际1 =4 hours

[0106] Wednesday: C 实际2 =3mg / m 3 , contact time t 实际2 =3 hours

[0107] Friday: C 实际3 =1.5mg / m 3 , contact time t 实际3 =2 hours

[0108] The national standard limit value of this chemical substance C standard limit value = 5mg / m 3

[0109] Calculation process:

[0110] First calculate

[0111] Monday: C 实际1 *t 实际1 =2mg / m 3 *4 hours = 8 mg / m3

[0112] Wednesday: C 实际2 *t 实际2 =3mg / m 3 *3 hours = 9 mg / m 3

[0113] Friday: C 实际3 *t 实际3 =1.5mg / m 3 *2 hours = 3 mg / m 3

[0114]

[0115] suggestion:

[0116] Because C 接触 =0.5<1, indicating that the level of workers' exposure to the chemical is below the standard limit and the risk is relatively low. However, we still need to continue to pay attention to the workplace environment to prevent the concentration from increasing.

[0117] Example 3.C 接触 >1 implementation examples, calculation processes and suggestions

[0118] Suppose a worker is exposed to another chemical during a work week.

[0119] The actual concentration Cactual of the chemical substance detected in the workplace and the contact time tactual are as follows:

[0120] Monday: C 实际1 =4mg / m 3 , contact time t 实际1 =5 hours;

[0121] Wednesday: C 实际2 =6mg / m 3 , contact time t 实际2 =4 hours;

[0122] The national standard limit value of this chemical substance C standard limit value = 5mg / m 3

[0123] Calculation process:

[0124] First calculate

[0125] Monday: C 实际1 *t 实际1 =4mg / m 3 *5 hours = 20 mg / m 3

[0126] Calculate the product of the concentration of the chemical substance to which the workers were exposed on Monday and the exposure time to obtain the exposure amount on Monday.

[0127] Wednesday: C 实际2 *t 实际2 =6mg / m 3 *4 hours = 24 mg / m 3

[0128] The product of the concentration of the chemical to which the workers were exposed on Wednesday and the exposure time was calculated to obtain the exposure amount on Wednesday.

[0129]

[0130] Finally calculate the C contact:

[0131] suggestion:

[0132] Since C contact = 1.1>1, this indicates that the level of workers' exposure to the chemical exceeds the standard limit, posing a high health risk. Immediate measures should be taken, such as improving ventilation systems, providing workers with more effective personal protective equipment, etc., and re-evaluating chemical control measures in the workplace to ensure the health and safety of workers.
