Noise occupational diseases, occupational disease hazards noise standards

Noise hazards should be prevented from three aspects: the sound source, the transmission path and the receiver.

l) control and elimination of noise sources, which is a fundamental measure to prevent noise hazards; Different solutions should be taken on a case-by-case basis. The use of silent or low-noise equipment instead of noisy equipment, such as hydraulic pressure instead of high-noise forging, welding instead of riveting, shuttleless instead of shuttled fabric, etc., can be better results. For noise sources such as fans and motors that are allowed to be remotely placed in production, they should be moved outside the workshop or isolated measures.

In addition, finding ways to improve the precision of the machine, minimizing the impact, friction and vibration of the machine components, can also reduce the production noise.

When designing a plant, the sound source should be reasonably configured. Noise hazards can also be reduced by separating high-noise factories from residential areas, and high-noise workshops from low-noise workshops.

2) There are generally the following measures to control noise transmission.

1) Sound absorption: Use sound-absorbing materials to decorate the inner surface of the workshop, such as walls and roofs, or hang the space sound absorber in the workshop to absorb radiation and reflected sound energy, so that the noise intensity is reduced. Materials with good sound absorption effect include glass wool, slag wool, foam plastic, felt, cotton wool, aerated concrete, sound-absorbing board, wood wool board, etc.

2) Silencer A device that prevents sound from propagating and allows air flow to pass through, i.e., a muffler. This is the main measure to prevent aerodynamic noise. Mufflers include resistive mufflers that use sound-absorbing materials to muffle sound, resistant mufflers that are manufactured according to the principle of filtering, and impedance composite mufflers designed using the above two principles.

3) Sound insulation In some cases, certain materials and devices can be used to close the sound source and isolate it from the surrounding environment, such as sound insulation cover and sound insulation room. The soundproofing structure should be tight so that resonances do not affect the soundproofing results.

4) Vibration isolation In order to prevent vibration and noise transmitted through solid materials such as floors and walls, vibration damping devices are set at the junction of the foundation of the machine and the floor and wall, such as rubber pads and asphalt.

5) Health care measures Strengthen personal protection, for the noise in the production site can not be controlled temporarily, or when it is necessary to work under special high-noise conditions, wearing personal protective equipment is an effective measure to protect the hearing organs. Earbuds are the most commonly used one, and the sound insulation effect can reach about 30 decibels. The sound insulation effect of earmuffs and hats is better than that of earplugs, but it is not convenient to use and the cost is also high, so it needs to be improved.

Workers who are exposed to noise should have regular health check-ups, especially hearing tests, to observe hearing changes, so as to detect hearing loss early and take appropriate protective measures in time. Workers participating in noisy operations should be subject to pre-employment physical examinations, and patients with auditory, cardiovascular and nervous system diseases should not participate in noisy operations.

For noisy workers, it is necessary to reasonably arrange rest time, such as the implementation of work breaks, and often supervise and inspect the implementation and effect of preventive measures.

According to the Occupational Disease Directory, noise-related is noise deafness.

According to the "Noise Occupational Health Standards", occupational exposure is 8 hours, the allowable standard for noise at the workplace is 85db (a) for 4 hours for occupation, the allowable standard for noise at the workplace is 88db (a) for 2 hours, the noise at the workplace is 91db (a) for 1 hour, the noise at the workplace is 94db (a) for occupational exposure hours, and the noise at the workplace is 97db (a) for occupational exposure hours. The allowable standard for noise at the workplace is 100 dB (a) for occupational exposure hours, and the allowable standard for noise at the work site is 103 dB (a) but the maximum can not exceed 115 dB (a).

Legal Analysis: Noise occupational disease patients who are identified as grade 5 or 6 disabilities shall enjoy the following treatments:

1. A one-time disability subsidy shall be paid according to the level of disability from work-related injury insurance, and the standard is: 18 months' salary for grade 5 disability and 16 months' salary for grade 6 disability;

2. Retain the labor relationship with the employer, and the employer will arrange appropriate work. If it is difficult to arrange work, the employer shall pay the disability allowance on a monthly basis, the standard is: 70% of the salary for the fifth grade disability and 60% of the salary for the sixth grade disability, and the employer shall pay all the social insurance premiums due to the employee in accordance with the regulations.

If the actual amount of disability allowance is lower than the local minimum wage, the employer shall make up the difference.

3. At the request of the injured employee, the employee may terminate or terminate the labor relationship with the employer, and the work-related injury insurance shall pay a one-time medical subsidy for work-related injury, and the employer shall pay a one-time disability employment subsidy. The specific standards for one-time medical subsidies for work-related injuries and one-time employment subsidies for disability shall be prescribed by the people of provinces, autonomous regions and municipalities directly under the Central Government.

Legal basis: Regulations on Work-related Injury Insurance

Article 21 Where an employee suffers a work-related injury and has a disability that affects his or her ability to work after the injury is relatively stable, an appraisal of his or her ability to work shall be conducted.

Article 22 The appraisal of labor ability refers to the grading appraisal of the degree of labor dysfunction and the degree of self-care impairment.

There are 10 levels of disability for labor dysfunction, with the most severe being level 1 and the least being level 10.

There are three levels of self-care disorders: complete inability to take care of oneself, inability to take care of oneself most of one's life, and partial inability to take care of oneself in life.

The standards for the appraisal of labor ability shall be formulated by the social insurance administrative department in conjunction with the health administrative department and other departments.

Abstract: Noise up to 80db constitutes an occupational hazard. According to the requirements of GBZ T Occupational Disease Hazard Classification in the Workplace Part 4: Noise, there are sounds that are harmful to hearing, harmful to health or other hazards, and noise exposure A is equivalent to 80dB for 8h d or 40h weeks is called noise work.

In the process of occupational disease certification, only workers engaged in noisy work can be diagnosed with occupational noise deafness. According to the GBZ Occupational Exposure Limits for Hazardous Factors in the Workplace Part 2: Physical Factors, the steady-state noise limit is 85dB(A) for 5 days per week and 8 hours per day, and the limit for the equivalent sound level of unsteady noise is 85dB(A); If the working day of the week is not 5d, the 40h equivalent sound level needs to be calculated, and the limit is 85 dB(a).

How much noise can be reached to constitute an occupational hazard.

Hello dear, I am the chair, I am happy to answer for you, your question has been received, please be patient and wait for you to answer

According to this, it is determined whether it is a noise occupational disease.

Dear, <>

The content of the occupational history certificate should be calculated from the time of the start of the noise exposure work, including the type of work, the length of service, the mode of exposure to noise or the characteristics of the operation, the daily or monthly exposure time, whether the noise is continuously exposed, and the environment of the workplace to determine whether it is an occupational disease.

Pro, the supplementary identification criteria generally refer to the continuous work in a noisy environment for more than three months, and the pure tone audiometry is relatively large or close to the auditory segment imitation mechanical examination shows high-frequency hearing loss, that is, meets the diagnostic criteria for noise-induced hearing loss, and the diagnostic standard for mild is an audiological examination between 26 and 40 decibels. The diagnostic criteria for moderate noise hearing loss are 40 to 55 decibels, and severe ones are greater than 55 decibels. [Love you grip].

Noise is a sound that people don't want. It often affects people's mood and health, interfering with people's work, study and normal life. Productive noise is divided into three categories:

Mechanical, aerodynamic and electromagnetic noise. Mechanical noise includes ball mill noise, shearing machine noise, locomotive noise and spinning machine noise. Aerodynamic noise includes fan noise, gas turbine noise, exhaust boiler venting noise, etc.

Electromagnetic noise includes generator noise, transformer noise, etc. Long-term work in a noisy environment without taking any effective protective measures will inevitably lead to permanent and irreversible hearing loss, and even severe occupational deafness.
