Occupational Hygiene Course

Lesson 1 • Defining Occupational Hygiene

Covers the history, definition, and global framework of occupational hygiene. Anchors all subsequent technical content in professional context.

Lesson 2 • Regulatory and Standards Framework

Surveys occupational health regulations, exposure standards, and enforcement mechanisms without jurisdiction-specific codes. Builds awareness of compliance obligations.

Lesson 3 • Occupational Hygiene Roles and Ethics

Defines professional duties, ethical codes, and stakeholder relationships. Prepares students to navigate conflicts of interest and confidentiality obligations.

Lesson 1 • Biological and Ergonomic Hazards

Addresses pathogens, allergens, musculoskeletal stressors, and psychosocial factors. Broadens hazard recognition beyond traditional chemical and physical agents.

Lesson 2 • Physical Hazard Recognition

Identifies noise, vibration, radiation, thermal stress, and lighting hazards. Links physical agents to physiological harm mechanisms.

Lesson 3 • Chemical Hazard Recognition

Covers identification of airborne contaminants, dusts, vapors, and gases. Connects chemical properties to exposure potential and health risk.

Lesson 1 • Skin and Systemic Chemical Hazards

Addresses dermal absorption, contact dermatitis, sensitizers, and systemic toxicants. Highlights skin as a significant exposure route often underestimated.

Lesson 2 • Fundamentals of Occupational Toxicology

Covers dose-response relationships, target organ toxicity, and toxicokinetics. Provides the biological foundation for evaluating chemical health risks.

Lesson 3 • Carcinogens and Reproductive Hazards

Covers occupational carcinogens, reproductive toxicants, and endocrine disruptors. Prepares students to apply precautionary principles for high-risk agents.

Lesson 1 • Statistical Analysis of Exposure Data

Applies lognormal distribution models, confidence intervals, and exceedance fractions to exposure data. Enables evidence-based compliance decisions.

Lesson 2 • Exposure Assessment Strategy Design

Covers similar exposure groups, sampling rationale, and tiered assessment approaches. Ensures students design statistically defensible monitoring programs.

Lesson 3 • Air Sampling Methods and Equipment

Introduces personal, area, and source sampling techniques with equipment selection criteria. Connects sampling method to contaminant type and exposure scenario.

Lesson 4 • Biological Monitoring

Explains biological exposure indices, specimen collection, and interpretation of biomarker data. Complements air monitoring with internal dose assessment.

Lesson 1 • Vibration Exposure and Assessment

Addresses hand-arm and whole-body vibration measurement, health effects, and exposure action values. Extends physical agent competency beyond noise.

Lesson 2 • Hearing Loss and Health Effects

Explains noise-induced hearing loss mechanisms, audiometric testing, and non-auditory effects. Links exposure data to health outcome prediction.

Lesson 3 • Noise Measurement and Surveys

Covers sound level meter and dosimeter use, survey design, and data recording. Connects measurement technique to accurate exposure characterization.

Lesson 4 • Acoustics and Noise Fundamentals

Introduces sound physics, decibel scale, frequency weighting, and noise metrics. Builds the quantitative foundation for noise measurement and assessment.

Lesson 1 • Non-Ionizing Radiation Hazards

Addresses UV, infrared, laser, and radiofrequency radiation sources, health effects, and controls. Covers the broad spectrum of non-ionizing radiation in workplaces.

Lesson 2 • Heat Stress Assessment and Control

Covers physiological heat strain, WBGT index, metabolic rate estimation, and acclimatization. Enables quantitative heat stress risk assessment in field conditions.

Lesson 3 • Cold Stress and Work in Cold Environments

Examines hypothermia, frostbite, wind chill, and cold work management strategies. Complements heat stress content with the opposite thermal extreme.

Lesson 1 • Control Verification and Effectiveness

Teaches post-control monitoring, performance metrics, and corrective action processes. Closes the control loop by confirming that implemented measures achieve target reductions.

Lesson 2 • Hierarchy of Controls Framework

Establishes elimination, substitution, engineering, administrative, and PPE controls in priority order. Provides the decision logic for all subsequent control design.

Lesson 3 • Confined Space and Process Safety Controls

Addresses permit-to-work systems, atmospheric testing, and emergency response for confined spaces. Extends control competency to high-hazard, non-routine work scenarios.

Lesson 4 • Personal Protective Equipment Selection

Guides selection, fit testing, maintenance, and limitations of respiratory and body protection. Ensures PPE is used correctly when engineering controls are insufficient.

Lesson 1 • Continuous Improvement and Performance Metrics

Establishes leading and lagging indicators, trend analysis, and management review processes. Drives ongoing program enhancement through data-informed decision-making.

Lesson 2 • Incident Investigation and Root Cause Analysis

Applies systematic investigation methods to occupational illness and near-miss events. Links root cause findings to corrective actions and program improvements.

Lesson 3 • Occupational Health and Safety Management Systems

Covers plan-do-check-act cycles, policy development, and integration with broader OHS frameworks. Positions hygiene as a structured organizational function.

Lesson 4 • Auditing and Inspection Techniques

Teaches internal audit planning, checklist development, non-conformance identification, and reporting. Builds capacity to evaluate program performance objectively.
