Physical hazards noise exposure

It should be recognized that the maintenance of any closed system can pose a hazardous exposure problem since most maintenance is performed while the plant is in operation and requires that workers be in close proximity to the operating equipment for long periods of time. Under such conditions, it is necessary to consider not only local contaminant releases but also physical hazards that may be present, such as noise and thermal radiation. 

Physical hazards are defined as the types of hazards that can cause harm to a woiker from an external source. Types of physical hazards are loud noise (equipment), temperature extremes (working in personal protective equipment), radiation (exposures to the infrared or gamma rays), chemical bum (acids or caustics), fire, and explosions. Other physical hazards include, but are not limited to, slips and falls, exposed machinery because of improper guarding, live electrical circuits or conductors, equipment moving about on site, confined spaces, and falling objects. 

Description of hazard. Water plant operators and associated maintenance staff are frequently exposed to noise levels that can be harmful to hearing. Noise sources include pumping and process equipment, alarms, generators, compressors, and ventilation equipment. Excessive noise exposure can cause temporary or permanent hearing loss, stress, and other physical problems. 

The workers in the poultry industry in any region are exposed to a number of risk factors in the execution of their activities, including exposure to dust, harmful gases, excessive noise and heat stress, and is subject to biological hazards chemical, physical, mechanical, ergonomic, social and accidents.
