Foundations of Workplace Health and Safety
1-2 weeksLearn the historical development of occupational health from Ramazzini to modern regulatory frameworks. Understand key agencies (OSHA, NIOSH, ILO, WHO) and foundational legislation such as the OSH Act of 1970.

Hazard Recognition and Classification
2-3 weeksStudy the major categories of workplace hazards: chemical, physical, biological, ergonomic, and psychosocial. Learn to identify hazards through workplace inspections, job hazard analyses, and safety audits.
Industrial Hygiene and Exposure Assessment
3-4 weeksMaster the principles of anticipating, recognizing, evaluating, and controlling workplace exposures. Learn sampling strategies, air monitoring techniques, noise measurement, and interpretation of occupational exposure limits (PELs, TLVs, RELs).
Hierarchy of Controls and Risk Management
2-3 weeksDeeply understand the hierarchy of controls framework. Practice applying elimination, substitution, engineering controls, administrative controls, and PPE to real-world workplace scenarios through case studies.
Occupational Toxicology and Disease
3-4 weeksStudy dose-response relationships, routes of exposure, acute versus chronic effects, and major occupational diseases including pneumoconioses, occupational cancers, dermatoses, and hearing loss. Learn biological monitoring principles.
Ergonomics and Musculoskeletal Health
2-3 weeksStudy the biomechanical, physiological, and psychophysical bases of ergonomics. Learn to conduct ergonomic assessments using tools such as RULA, REBA, and the NIOSH Lifting Equation, and design interventions for common WMSDs.
Occupational Epidemiology and Surveillance
2-3 weeksLearn epidemiological study designs used in occupational health (cohort, case-control, cross-sectional), surveillance systems, and how to interpret occupational health data to identify trends and causal relationships.
Psychosocial Health, Total Worker Health, and Emerging Issues
2-4 weeksExplore psychosocial hazards, workplace mental health, shift work, and the Total Worker Health framework. Examine emerging challenges such as nanotechnology hazards, telework ergonomics, gig economy protections, and climate-related occupational risks.
