Introduction
In legal and compliance contexts, industrial hygiene and occupational health play an indispensable role in ensuring workplace health and safety, and addressing the associated potential liabilities. As industries evolve and workplace complexities increase, these disciplines have become critical in both illness and injury prevention and litigation.
Defining Industrial Hygiene and Its Role in Workplace Safety
Industrial hygiene is the science of anticipating, recognizing, evaluating, and controlling workplace conditions that may cause illness or injury. This discipline focuses on hazards such as chemical and biological exposures, as well as physical exposures, such as noise and radiation. By identifying and mitigating these risks, industrial hygienists help ensure compliance with health regulations and safeguard employee well-being.
In a legal setting, industrial hygiene insights are invaluable. They provide the technical foundation for recognizing and evaluating potential exposures that may be associated with illness and injuries, compliance with standards like those set by OSHA (Occupational Safety and Health Administration) and demonstrating how failures to meet these standards may or may not lead to damages.
