local ventilation systems. Controls change how the task is performed. Some of the basic work practice controls include: following the laid procedures to reduce exposures while at the workplace, inspecting and maintaining processes regularly, and implementing reasonable workplace procedures. Industrial hygiene in the United States started taking shape in the early 20th century. There before, many workers risked their lives daily to work in industrial settings such as manufacturing, mills, constructions, and mines. Currently, the statistics on work safety are usually measured by the number of injuries and deaths yearly. Before the 20th century, these kinds of statistics were hard to come by because it appeared no one cared enough to make tracking of the job injuries and deaths a priority. The industrial hygiene profession gained respectability back in 1700 when Bernardino Ramazzini published a comprehensive book on industrial medicine. The book was written in Italian and was known as De Morbis Artificum Diatriba, meaning “The Diseases of Workmen” (Geigle Safety Group, Inc., 2020). The book detailed the accurate description of the occupational diseases that most of his time workers suffered from. Ramazzini was critical to the industrial hygiene profession's future because he asserted that occupational diseases should be studied in the workplace environment and not in hospital wards. Industrial hygiene received another boost in the early 20th century when Dr. Alice Hamilton led an effort to improve industrial hygiene. She began by observing industrial conditions first and then startled mine owners, factory managers, and other state officials with evidence that there was a correlation between workers` illnesses and their exposure to chemical toxins. She presented a definitive proposals for eliminating unhealthful working conditions. As a result, the US federal government also began investigating health conditions in the industry. In 1911, the states passed the first workers` compensation laws. The social role of occupational hygiene Occupational hygienists have been involved historically with changing the perception of society about the nature and extent of hazards and preventing exposures in the workplace and communities. Many occupational hygienists work day-to-day with industrial situations that require control or improvement to the workplace situation. However larger social issues affecting whole industries have occurred in the past e.g. since 1900, asbestos exposures that have affected the lives of tens of thousands of people. Occupational hygienists have become more engaged in understanding and managing exposure risks to consumers from products with regulations such as REACh (Registration, Evaluation,
