Industrial Hygiene is the science and art dedicated to the anticipation, recognition, evaluation, and control of workplace hazards that can cause worker injury, illness, or impairment. As a specialized field within industrial engineering, it applies scientific and engineering principles to analyze and mitigate environmental factors and stresses, such as chemical exposures, physical agents like noise and radiation, biological contaminants, and ergonomic risks. The primary objective is to engineer controls and modify work processes to create and maintain a safe and healthy environment, thereby protecting the well-being of the workforce and preventing occupational disease.
