Workplaces may contain factors with adverse health effects including chemical (vapor or particulates), physical (noise or radiation), biological (bacteria or viruses), ergonomic (bad working positions or heavy loading), social-psychological (pressure) factors. This course module introduce how to promote the health of workers through anticipating, recognizing, evaluating, and controlling hazardous factors.

This module includes the following seven required courses, which account for 15 credits. 

1. Principles of Environmental and occupational toxicology (2credits): The course introduces the principles of toxicology, including toxicokinetics, toxicodynamics, and mechanisms of toxic actions. Examples of environment toxicological studies and lab tours will also be provided.

2. Monitoring for Health Hazard at Work I (2credits): This course utilized both lectures and lab experiments to enable students to know the theories, methods, and interpretation of results on occupational hazards. The content includes the determination of occupational chemical hazards in the air such as organic solvent, vapor, suspended particulates, trace metals. The sampling and analysis of biological hazards in the air will also be discussed.

3. Monitoring for Health Hazard at Work II (2credits): Connecting with the above course, this course focuses on occupational physical hazards, such as noise, vibration, temperature and humidity, ionized and non-ionized radiations.

4. Industrial Ventilation (2 credits): This course includes both lectures and hands-on jobs, which introduces basic airflow principles, local exhaust system design and dilution ventilation system design, selection of air cleaner and measurement instruments.

5. Risk Assessment (3credits): This course introduces students to search for the best available scientific information, to integrate the info with updated methods used by the international community, to predict the probability of harms caused the chemicals of interests, and interpret results with potential uncertainties. The assessment can be the basis for making scientifically-sound public policies. 

6. Personal Protective Equipment (2credits): This course introduces various personal protective equipment such as respiratory protection apparatuses, clothes for preventing skin from absorption, isolation and control of noise, etc. The course content contains physiological effects, protection mechanisms, selection of protection equipment, and measurement of the protection efficiency.

7. Industrial Safety (2credits): This course introduces common hazardous factors that affect safety in the workplace, including machinery equipment, boilers and pressure vessels, electrical safety technology, fall disasters, and constructions. Course content includes safety theory, hazard analysis, case sharing, and precautionary measures.

After finishing this module, students shall be able to prevent and solve problems on factors impacting on occupational health and safety. Students can be the manager of occupational safety and health in industry, as a technical consultant after getting the license of occupational health technician, or work for a governmental agency if passing the official exams.
