Occupational Hazards Identified A. Physical Agents The physical agents identified as a health hazard during our industrial visit were noise and temperature. Large furnaces and boilers are being used for production in one portion of the factory. This leads to an increase in temperature in the surrounding work area. The building where the furnaces are in is left open with some ventilation shafts but the surrounding area in still warm. Water cooler stations should be provided in order to prevent dehydration during prolonged work hours.
