Society has become more educated on the impacts on human health and environment, and there has been a noticeable decrease in the acceptance of this risk by workers and the public.However, to ensure a higher level of worker protection, a revised approach to industrial hygiene is needed focusing on risk-reduction.This second edition of Industrial Hygiene focuses on implementation of an industrial hygiene program, using a risk-based approach, in an operational environment.Key elements of this book include balancing the art and science of industrial hygiene, risk-based industrial hygiene approaches, recognizing, evaluating, and controlling workplace hazards, medical monitoring for workers, emergency response, training, and evaluating industrial hygiene programs.Updated concepts on leadership, emergency response and monitoring, management of industrial hygiene projects, and risk communication are addressed in this edition.The book incorporates the ISO 45001 standard, “Occupational Health and Safety,” into an industrial hygiene program, which further demonstrates a risk-based approach that is internationally recognized.This is an ideal read for any student, researcher, or practitioner in the fields of occupational health and safety, industrial hygiene, risk management, and hazard control.New case studies with proposed solutions underpin the learning, and the instructor resource pack comprising PowerPoint presentations, question bank, and resources to enhance learning are available in this edition for qualified textbook adoption.
