This topic will provide an overview of occupational safety and health, including the importance of workplace safety, key terminology, historical context, and relevant regulations.
Introduction to Occupational Safety and Health (OSH)
Key concepts, objectives, and foundational elements for creating safe workplaces.
1. What Is Occupational Safety and Health?
| Term |
Definition |
| Occupational Safety |
Practices that protect workers from accidents, injuries, and hazardous incidents that occur while performing job duties. |
| Occupational Health |
Measures that preserve and promote workers’ physical, mental, and social well‑being, focusing on disease prevention, ergonomics, and exposure control. |
| OSH (Occupational Safety and Health) |
Integrated approach that combines safety and health to prevent work‑related injuries, illnesses, and fatalities. |
2. Core Objectives of OSH
- Prevent Injuries & Illnesses – Eliminate or reduce hazards before they cause harm.
- Comply with Legal Requirements – Meet national and international regulations (e.g., OSHA, EU‑OSHA, ILO conventions).
- Promote a Safety Culture – Foster attitudes, beliefs, and behaviors that prioritize health and safety at all organizational levels.
- Enhance Productivity – Healthy workers are more efficient, have lower absenteeism, and contribute to higher quality output.
- Protect Assets & Reputation – Reduce costs from accidents, legal claims, and damage to brand image.
3. Legal Framework (U.S. Example)
| Level |
Description |
| Federal |
Occupational Safety and Health Act (OSHA) – sets standards, enforces compliance, provides training. |
| State |
State‑run OSHA programs (e.g., California’s Cal/OSHA) may have stricter rules. |
| Industry‑Specific |
Standards for construction, maritime, agriculture, etc. |
| International |
ILO Convention 155, ISO 45001 (Occupational Health & Safety Management Systems). |
Key legal concepts:
- Employer duties – provide safe workplace, training, PPE, hazard communication.
- Employee rights – receive training, report hazards, refuse unsafe work without retaliation.
- Enforcement tools – inspections, citations, fines, possible criminal penalties.
4. Hazard Identification & Risk Assessment
4.1 Types of Workplace Hazards
| Category |
Examples |
| Physical |
Noise, vibration, radiation, extreme temperatures, machinery. |
| Chemical |
Solvents, gases, dust, fumes, hazardous substances. |
| Biological |
Bacteria, viruses, fungi, mold. |
| Ergonomic |
Repetitive motion, awkward postures, manual handling. |
| Psychosocial |
Stress, harassment, shift work, workload pressure. |
| Safety |
Unguarded equipment, slips/trips/falls, electrical hazards. |
4.2 Risk Assessment Process
- Identify hazards (walk‑throughs, job safety analyses, incident reports).
- Analyze likelihood and severity of potential outcomes.
- Evaluate risk level (e.g., low, medium, high) using a risk matrix.
- Control hazards (apply hierarchy of controls).
- Review and update regularly or after any change.
5. Hierarchy of Controls
| Level |
Control Method |
Typical Application |
| 1. Elimination |
Remove the hazard entirely. |
Automate a dangerous task. |
| 2. Substitution |
Replace with a less hazardous alternative. |
Use water‑based paint instead of solvent‑based. |
| **3. Engineering |
