 Dear students, the topic which we are going to discuss is Hazard Assessment, Prevention and Control. Now we are going to discuss with the help of workers' compensation and noise. Whenever we talk about workers' compensation, it means that we are talking about incentives, benefits of the employees which they are getting from the organization. Workers' compensation and noise. In making determinations of such a relationship, physicians consider the following factors. Onset and progress of the employees' history of hearing loss. The employees complete work history. Employees are seen to have a lot of loyalty with the organization in their historical perspective for the whole life. If there is a loss, hearing loss or physical problems, then the employee is compensated for. Results of implies ontological examination. Results of hearing studies that have been performed. Determinations of weather causes of hearing loss originated outside the workplace. The problem which we have to face is within the organization. Is it done outside the organization? If it is outside the organization, then the organization will not take its responsibility. Why and assessing hazardous noise conditions in the workplace involve number one, conducting pre-automatic noise survey, conducting pre-automatic automatic test, record keeping and follow-up actions. These four things are basically a process in which we see that the employees' noise, organizational noise, workplace noise is affecting the employees. Pictorial effect dear students. Right ear, left ear, left ear, left ear and this is the complete detail of how these technical things are fit for them and whether they are eligible or not to work physically. Noise control strategies, noise receiver, noise path and noise source. Noise can be reduced by engineering and administrative control. Engineering control dear students, that control is in which technical, electronic, mechanical, mechatronics, technical experts are involved. Administrative control is the top management, supervisor, marketing head, finance head, these people are involved. So here if you want noise control, you will have to technically and administrative control both of them have to be applied to the organization. Noise control strategies, noise can be reduced as its source by enclosing the source, altering the acoustical design at the source. Sometime organization may come to a change in machine so that the source creates noise and it ends in the start. Noise control strategies, noise can be reduced along its path by moving the source further from the receiver and improving the occupational design to the path. The technical path from where the noise is being submitted and where it is being received is enhancing the space in the middle. Sometime the noise created is also snubbed. Number two, when the space is enhanced, the noise can be reduced. Number three, technical expertise required can be used to help the noise. Noise control strategies, safety and health professionals, if they want safety and noise control in the organization, they will have to follow two things. First, engineering control and second, administrative control. Administration control has technical expertise and administrative control has management expertise. If both of them work together, then you can be able to control hazard assessment, prevention and control in the organization.
