Survey Of Noise Pollution In Weaving Unit Of Parsabaft Textile Factory And Providing Some Noise Control Ways
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2016, Vol 10, Issue 7
Abstract
Introduction: One of the risks always threatening human is the workplace hazards disturbing his life in various forms. One harmful factor in textile industry is the noise pollution existing in almost all units, affecting the health of workers, area residents and environment negatively.Material and Methods: This is a field study investigating the risk of noise pollution in weaving unit, north part of the factory and administration office (which is located) next to the weaving unit in a textile plant in Tehran. To measure the noise environmentally we use A noise analyzer model “TES 1358” was used to measure simple noise and with frequency analysis in octave frequencies and also noise dosimeter model “TES 1355” was used to investigate individual exposure.Results: For this purpose, the level of noise was measured in 111 stations in different parts and the results were compared with standards defined in ACGIH and EPA and The level of pollution spread were demonstrated using GIS maps charts and based on justified charts. The results Showed that noise level in most Stations exceeded the permissible level authorized (higher than 85 dBA in production unit and higher than 65 dB in administration unit). Also, based on the questionnaire investigating the comfort and protection level of the helmets it was revealed that used helmets were not were used not able to protect the workers against the existing noise.Discussion and conclusion: To control noise it was designed and suggested to install a 3 layer KENAF partition surrounding winder machines and also suspended acoustic tile and foam on top of the machine. Thus, some plans and schemes were developed to decrease the level of the noise pollution. Proposition: Substitution some weaving machines (for example electronic machines that are 6 meter instead of electronic and mechanical machines that are 3 meter) or changing some parts of machines (using Teflon gears instead of metal gears), periodical services, some environmental renovations are needful for noise reduction.
