of occupational hygiene can often be referred to as the "art" of occupational hygiene and is used in a similar sense to the "art" of medicine. In fact "occupational hygiene" is both an aspect of preventive medicine and in particular occupational medicine, in that its goal is to prevent industrial disease, using the science of risk management, exposure assessment and industrial safety. Ultimately professionals seek to implement "safe" systems, procedures or methods to be applied in the workplace or to the environment. Prevention of exposure to long working hours has been identified as a focus for occupational hygiene when a landmark United Nations study estimated that this occupational hazard causes an estimated 745,000 occupational fatalities per year worldwide, the largest burden of disease attributed to any single occupational hazard. Industrial Hygiene refers to the science of anticipating, recognizing, evaluating, and controlling workplaces to prevent illness or injuries to the workers (Geigle Safety Group, Inc., 2020). Industrial hygienists use various environmental monitoring and analytical methods to establish how workers are exposed. In turn, they employ techniques such as engineering and work practice controls to control any potential health hazards. Anticipation involves identifying potential hazards in the workplace before they are introduced. The uncertainty of health hazards ranges from reasonable expectations to mere speculations. However, it implies that the industrial hygienist must understand the nature of changes in the processes, products, environments, and workforces of the workplaces and how they can affect workers' well-being. Recognition of engineering, work practice, and administrative controls are the primary means of reducing the workers` exposure to occupational hazards. Timely recognition of hazards minimizes the workers' exposure to the hazards by removing or reducing the hazard's source or isolating the workers from the hazards. Evaluation of a worksite is a significant step that helps the industrial hygienists establish jobs and worksites that are a potential source of problems. During the evaluation, the industrial hygienist measures and identifies the problem tasks, exposures, and tasks. The most effective worksites assessment includes all the jobs, work activities, and operations. The industrial hygienists inspect research and evaluations of how given physical or chemical hazards affect the workers' health. If the workplace contains a health hazard, the industrial hygienist recommends appropriate corrective actions. Control measures include removing toxic chemicals and replacing harmful toxic materials with less hazardous ones. It also involves confining work operations or enclosing work processes and installing general and
