    Evaluation of Heat Stress Exposure to Occupational Workers at Workplace

    By Pallavee Vitti Krushna, Nishith Ghosh, Jagdish D Sharma, Alok Srivastava

    Abstract: Heat stress is considered as an occupational health hazard encountered in indoor as well as outdoor environments. In industries, many operations are carried out which involve either heat generating sources like boiler, furnace, dryers etc. or hot operations like welding, melting, glass blowing and pouring. Moreover, the extremes of temperature in summer also add to the level of exposure to heat stress. Exposure of occupational workers to heat stress can …

    Occupational Exposure to Vibration – Hazards, Evaluation and Control

    By Nishith Ghosh, Garima Singh, G.L.N. Padmavathi, Aparna Sawatkar, M.D. Patel, Alok Srivastava

    Abstract: Mechanical vibration is known to cause occupational health hazards. Exposure to vibration has potential to cause musculoskeletal disorders. Chronic exposure to hand-transmitted vibration causes occupational disease like vibration induced white finger (VWF). This article describes the harmful health effects caused due to exposure to hand-transmitted vibration (HTV) and whole-body vibration (WBV) and the control measures to minimize the exposure. Specifically, focus is kept on the evaluation of vibration exposure to …

    Assessment of Acoustic Noise Generated from Machines in a Mechanical Workshop Using 1-Octave Band Frequency Analysis

    By Nishith Ghosh, Aparna R. Sawatkar, J. D. Sharma, A. S. Vajarekar

    Abstract: Acoustic noise is one of the prominent occupational health hazards, particularly in manufacturing and process industries. Prolonged exposure to loud noise can cause noise induced hearing loss of the exposed personnel. Limiting the exposure to noise intensity within its permissible exposure limit is adopted as one of the administrative control measures to reduce the risk of hearing loss. However, frequency specific assessment of occupational noise exposure is limited. Here, we …
