MEASURES TO REDUCE NOISE IN PRODUCTION WORK
Noise pollution in Industrial production is a collection of sounds emitted by machinery and equipment during production activities, causing workers to feel uncomfortable and, in the long run, affecting their working health. workers.
PERMITTED NOISE LEVEL IN INDUSTRIAL PRODUCTION
- Continuous sound level at the workplace must not exceed 85 dBA in 8 working hours
- Noise exposure time is reduced by half, the allowable noise level increases by 5 dBA, specifically as follows:
  • For 4 hours exposure, the allowable level is 90 dBA.
  • 2-hour exposure is allowed at 95 dBA.
  • The permissible exposure level for 1 hour is 100 dBA.
  • 30-minute exposure level is 105 dBA. (/)
- During the remaining working time of the working day, you can only be exposed to noise below 80 dBA.
- To achieve high productivity at different working positions, it is necessary to ensure that the sound pressure level does not exceed the following values:
+ Rooms for mental labor, design research, statistics, computer programming, theoretical laboratories and experimental data processing sound levels must not exceed 55 dBA.
+ Work places of workers, areas where workers work in workshops and factories, sound levels must not exceed 85 dBA.
+ Remote monitoring and control rooms without telephone information, laboratories, experimental rooms, and computer rooms with noise sources with sound levels not exceeding 80 dBA.
+ Remote monitoring and control room with telephone information, coordination room, precision machine installation room, typing sound level no more than 70 dBA.
+ Functional, administrative, accounting, planning, and statistical departments have sound levels not exceeding 65 dBA.
SAFE WORKING MEASURES:
- Isolate the source of noise: The factory should be designed far away from the office area. The surrounding wall design helps shield it with foam materials, soundproofing cotton, and planting trees.

- Regularly check and lubricate grease and replace rotating shaft bearings to keep the machine running smoothly.
- Employees working in noisy environments need to be equipped with earmuffs and noise-canceling earplugs.
- Do not assign people with hearing damage, neurological impairment, or cardiovascular disease to work in environments that generate noise in excess of allowed hygiene standards.
- Reduce working time exposed to noise, take breaks in between shifts in quiet areas. Organize mid-shift training to prevent diseases and ensure workers' health if all toxic factors in the working environment have not been overcome.
- Annually measure the working environment and examine and detect occupational deafness.
- Regularly and periodically train workers exposed to noisy environments to know the harmful effects of noise and safe working measures.
