Hazardous propagation of noise in a surface mine industry: An Occupational Health study
( Dayal Dev S ),( Vignesh K. S ),( Radha Krishnan R ) 한국감성과학회 2023 한국감성과학회 국제학술대회(ICES) Vol.2023 No.-
Noise risk assessment is an essential component of occupational hazard management in workplace safety, whether it is underground or open pit mining, workers are exposed to loud noise during work such as heavy machine drilling, blasting, trucks are some loud noise emitters. Globally, occupational noise is responsible for approximately 16% of the disabling hearing loss in adults, equivalent to over 4 million Disability-Adjusted Life Years (DALYs), in India prevalence rate of Noise Induced Hearing Loss (NIHL) is 12.8% among mine employees in various environments. Main parameter was to measure the exposure level of noise using dosimeter in various operating conditions. Findings of our study states the noise exposed around various working environments 86.6 dB(A) near rock breaker and 92.9 dB(A) near Xcentric ripper which is higher than the Recommended Exposure Limit (REL) recommended by National Institute of Occupational Study and Health (NIOSH) and Directorate General of Mines Safety (DGMS). Employees exposed to noise more than PEL for a prolonged period of time have higher risk of Tinnitus, NIHL and other hearing ailments. Usage of hearing protectors for employees should be made compulsory and breaks between working hours need to be improvised by the employers according to the standards prescribed.
