Presentation 1 for Unit 1 in HPEO 403

1. Unit 1 - Part 1:Introduction to Occupational Health HPEO 408 Occupational Health Hazards

2. Goal is to protect and promote the health, safety, and wellness of workers. Injuries Illnesses Diseases Deaths How? … PREVENTION! Occupational Health and Safety Program 2 Occupational Health

3. Written plan to prevent accidents and occupational diseases BC regulations (Part 3.1) Workplace >20 employees and moderate risk to create injury Workplace >50 employees Elements Responsibilities Written rules and standard operating procedures Maintenance of program records/statistics Provisions for inspections, meetings, investigations, and training 3 Occupational Health and Safety Programs

4. 4 Hygiene Paradigm

5. Proactive step, linked with recognition Through: Work process / job tasks Equipment /operations Materials (raw, intermediate, and end materials) Anticipation of new hazards Change in equipment/materials Future legislation/regulations New research Consider design stage vs. operational stage 5 Anticipation

6. All hazard types (3 main classes) Chemical Biological Physical Ergonomic*, Psychological*, Mechanical (safety)** Routes of exposure inhalation, skin absorption, ingestion Other considerations Multiple exposure effects (Synergistic/antagonistic ) Workforce (age, health conditions) Other non-occupational exposures 6 Recognition

7. The workplace: Historical data (exposure data, accident/incident or illness reports) Process information Walkthrough (observations, talking with workers) Regulatory or non-regulatory government agencies (ex. WCB, CCOHS, NIOSH): process, toxicological, control information injury and disease trends by sector regulations/guidelines 7 Hazard Identification Resources

8. Non specific references for process/toxicological/material information: textbooks, research journals, MSDSs, Other internet sites Suppliers/manufacture of equipment and materials Union or professional organizations processes, chemicals used, and controls available (sometimes) Consult Colleagues, Specialists (i.e. academics), or Consultants 8 Hazard Identification Resources

9. Sampling strategy (who, where, when, why, how) Measurement of hazards Exposure intensity (i.e. exposure levels) Probability of exposure (frequency, duration) Routes of exposure Data Evaluation (i.e. calculations) Exposure calculation Judgment Standards/regulations Other professional recommended guidelines Internal company standards 9 Evaluation

10. Hierarchy of control measures Elimination Substitution Engineering Administrative Personal Protective Equipment (PPE) Influences on selection of controls: Design phase vs. operational phase Costs (start up, ongoing, maintenance) Ease / usability / effectiveness Ability to integrate Availability 10 Controls

11. Important step often forgotten Re-evaluation needed: After controls put in place Effectiveness (initial and ongoing) Changes in operations/materials in process Annual review Regulation changes 11 Re-evaluation

12. The Occupational Health Team Managers HR Occupational health Safety Health Promotion Safety Safety officers/technicians Emergency or rescue workers Emergency Preparedness coordinator Security Health Promotion Rehabilitation Return to work coordinator Wellness coordinator Generalists OH&S coordinator HS&E coordinator Environmental Environmental coordinator Environmental sustainability Other specialists Industrial hygienist /technicians Ergonomists Audiologist Hazardous waste management coordinator Occupational nurse Occupational physician 12

13. Chapter 1 (pg 3 – 32) Provides an introduction of occupational health and the topics we will be covering throughout the course. Chapter 23-26 (pg 727 – 791) Skim/browse chapters only Provides information on various occupational health professions 13 Readings
