The focus of industrial hygiene in occupational health nursing is primarily on the identification, evaluation, and control of environmental factors that may adversely affect workers' health. This area of practice is dedicated to recognizing potential hazards in the workplace, such as chemical exposures, physical agents (like noise or radiation), and biological hazards. By assessing these environmental conditions, industrial hygienists can then implement control measures to mitigate risks and enhance worker safety.

The core principle of industrial hygiene revolves around understanding how workplace exposures can lead to health issues, and taking proactive steps to minimize these exposures. This ensures not only compliance with regulations but also promotes a healthier work environment, ultimately benefiting both employees and employers through reduced illness and injury rates.

Other choices revolve around immediate healthcare needs, physical health promotion, or first aid; however, they do not encompass the broader scope of preventive measures and environmental control that defines the primary role of industrial hygiene in occupational health.
