Study Notes

Introduction to Occupational Hygiene

Occupational hygiene is a preventive science that aims to protect the health of workers and others affected by workplace hazards.
Occupational hygienists come from various backgrounds (engineering, physics, chemistry, biology) and acquire expertise in health effects and control measures through postgraduate study and experience.

Roles of Occupational Hygienists and Occupational Health Physicians

Occupational hygienists focus on preventing exposure to health hazards and controlling health risks in the workplace through monitoring, analytical methods, and engineering controls.
Their role is purely preventive, focusing on the source of the problem (hazard) and how to prevent or minimize contact.
Occupational health physicians, on the other hand, concern themselves with early disease detection through specific tests and examinations, and management of occupational poisoning and disease cases.
Their role is both preventive and curative.

Principles of Occupational Hygiene

Occupational or industrial hygiene is defined by the American Industrial Hygiene Association (AIHA) as a science and art devoted to anticipating, recognizing, evaluating, and controlling environmental factors and stresses in or from the workplace that may cause sickness, impaired health, or significant discomfort.
Occupational hygienists address chemical, physical, and biological hazards that may cause health risks to workers.
The principles of occupational hygiene involve:
- Anticipating potential health risks
- Recognizing existing health hazards at the workplace
- Evaluating exposure and assessing risk situations
- Controlling unacceptable risk situations

Anticipation of Potential Health Risks

Anticipation of potential health risks is crucial in preventing occupational diseases or poisoning, especially during the design stage of a process or in the formulation of new chemicals.
Early interventions can prevent costly interventions later on.
Factors to consider when anticipating potential health risks include process characteristics, chemical properties, health effects, past experiences, and similarity to known hazardous chemicals.

Chemical Hazards

Chemical substances pose significant health hazards to workers due to their potential to cause fires, explosions, health effects, or environmental damage.
Chemical hazards can be classified according to physical form or by their physicochemical properties.
