Diagnosis and identification of occupational noise defects

I. Materials for Applying for Occupational Noise and Diagnosis

Workers who apply for diagnosis of occupational diseases should submit an application, proof of their own health damages, and proof of the occupational history provided by the employer. The content of the proof of occupational history shall start from the time when noise exposure begins, including the type of work, length of service, contact noise or operating characteristics, daily or monthly contact time, continuous exposure to noise, environmental conditions at the workplace, and Noise facilities and their effects, workplace noise detection data, personal protection, etc.

The employer shall truthfully provide the occupational history of the occupational disease and the exposure history of occupational hazards and occupational hazards, and the detection results of occupational hazards in the workplace. The safety production supervision and administration department shall supervise, inspect and urge the employer to provide the above-mentioned information; And related organizations should also provide information related to the diagnosis and identification of occupational diseases.

Second, in the process of occupational disease diagnosis and appraisal, how does the employer not provide relevant information?

In the process of diagnosis and appraisal of occupational diseases, if the employing unit does not provide data on the detection results of occupational hazards in the workplace, the diagnostic and appraisal agency shall combine the clinical manifestations of the workers, the results of the auxiliary examinations, the occupational history of the workers, and the exposure history of occupational hazards, and Refer to the self-reported by the laborer, the day-to-day supervision and inspection information provided by the production safety supervision and administration department, and if the occupational disease diagnosis and appraisal conclusion is made, and the laborer cannot provide a proof of the occupational history, the labor relationship certification materials may be submitted as supporting evidence. The proof of labor relations shall be based on the labor contract, the arbitral award of labor relations or the judgment of the court, and the materials recognized by the employer.

When an employer has not signed a labor contract with a laborer or the labor contract expires, and the employer has terminated the labor contract, when the laborer applies for occupational disease diagnosis, if the employer denies the labor relationship with the laborer, the laborer provides any of the following The certificate has been confirmed by the labor department that occupational disease diagnostic institutions can serve as the basis for occupational noise and diagnosis:

Data that can prove labor relations, such as wage payment vouchers or records (payroll payroll), records of various social insurance premiums paid, etc.; information that can indicate the identity of the laborer, such as "identity card", employer to laborer Certificates such as “work permits” issued; information that can prove the relationship between employers and recruiters, such as employer recruitment recruitment “registration form”, “registration form” and other recruitment records; attendance records and testimony of more than three other laborers Wait.

Third, how to do with the information provided by the employer?

If the laborer has any objection to the results of the occupational hazards test results provided by the employing unit, or if the employer’s employer is dissolved or bankrupt, if the employer provides the above information, the diagnostic and appraisal agency shall submit it to the safety production supervision and management department. Conduct an investigation. The safety production supervision and administration department shall, within 30 days from the date of receiving the application, make a determination on the data on objections or the occupational hazard factors in the workplace, and the relevant departments shall cooperate.

If the laborer has disputes over labor relations, types of work, work positions, or on time, he may apply to the local labor and personnel dispute arbitration committee for arbitration. The labor and personnel dispute arbitration committee that has received the application shall accept the application and make an award within 30 days.

If the laborer cannot provide evidence concerning arbitration claims held by the employing unit, the arbitral tribunal shall require the employing unit to provide within a specified time limit; if the employing unit does not provide within a specified time limit, it shall bear adverse consequences.

Workers who are dissatisfied with the arbitral award may file a lawsuit with the people's court according to law.

Fourth, where to diagnose occupational noise?

The State stipulates that the diagnosis of occupational noise sickness must be carried out by a medical and health institution that has undertaken occupational disease diagnosis approved by the health administrative department of the people's government of the province, autonomous region or municipality directly under the Central Government. Workers may conduct occupational noise diagnosis at the medical and health institutions that are legally responsible for the diagnosis of occupational diseases at the place where the employing unit is located, where the person's household registration is located, or where they frequently live.

V. Classification and Diagnosis of Occupational Noise Caries

Continuous noise work for more than 3 years of service, pure tone audiometry sensorineural hearing loss, hearing loss showed a high-frequency drop type, based on better hearing frequency (500Hz, 1000Hz, 2000Hz) average hearing threshold, to make a diagnostic rating.
Mild noise: 26dB to 40dB (HL)
Moderate noise 聋: 41dB to 55dB (HL)
Heavy noise 聋: ≥56dB(HL)

Sixth, what factors do you need to diagnose occupational noise?

There is a clear history of exposure to occupational noise; there are conscious hearing loss or tinnitus symptoms, pure tone audiometry is sensorial hearing loss; combined with occupational health examination data and on-site hygiene surveys over the years; there is no evidence to deny noise and noise deafness between patients. Those who are inevitably linked should be diagnosed as occupational noise.

7. What to do if there is objection

If a worker disagrees with the diagnosis of occupational noise, he or she may apply for appraisal to the health administrative department of the local people's government where the medical institution that made the diagnosis is located.

The occupational noise and diagnostic disputes shall be submitted by the health administrative department of the local people's government at or above the municipal level according to the application of the parties, and an occupational disease diagnosis and appraisal committee shall be established to conduct the appraisal.

If workers are still dissatisfied with the appraisal conclusions of the municipal-level occupational disease diagnosis and appraisal committee, they may apply for re-appraisal to the health administrative departments of the people's governments of provinces, autonomous regions and municipalities directly under the Central Government. Provincial occupational disease diagnosis and identification is the ultimate identification.

Eight, the principle of treatment for patients diagnosed with occupational noise

Observers do not need to be removed from the noise workplace, but at the same time there are exceptions for tinnitus; patients with mild, moderate, and severe noise should be removed from the noise workplace, labor capacity appraisers need to be identified, and labor capacity appraisal “Injury and occupational disability rating” treatment; patients with severe noise should wear hearing aids; sensitive to noise (that is, check the normal hearing before starting work, work in a noisy environment for 1 year, high frequency 3000 Hz, 4000 Hz, 6000 Hz any Frequency, 65 dB (HL) on either ear should be removed from the noise workplace.

Nine, occupational noise treatment

There are currently no effective treatment methods for occupational noise. Therefore, hearing protection should be conducted in the early stage, and noise reduction earmuffs or earplugs should be selected in accordance with the work environment. It is important to strengthen prevention and control measures.
