1. Workshop Safety: Identifying and Managing Hazards Workshop Hazards

2. Introduction to Workshop Safety Why Safety Matters:  Prevent injuries, accidents, and property damage. Workshop Environment:  Tools, machinery, materials, and human factors. Goal of the Lesson:  Identify common hazards and learn how to prevent them.

3. Types of Workshop Hazards Physical Hazards Chemical Hazards Biological Hazards Ergonomic Hazards Electrical Hazards Fire and Explosion Hazards Psychological Hazards

4. Physical Hazards Definition: Physical dangers that can cause injury or harm. Examples: Sharp Tools: Blades, chisels, saws. Moving Machinery: Saws, lathes, routers. Heavy Objects: Lifting or moving large materials. Slippery Floors: From spilled liquids or sawdust. Noise: From power tools and machinery. Flying Debris: From cutting or grinding.

5. Physical Hazards Definition: Physical dangers that can cause injury or harm. Prevention: Use proper PPE (gloves, goggles, ear protection). Keep work area clean and organized. Use guards on machinery. Avoid loose clothing or jewelry.

6. Chemical Hazards Definition: Hazards from exposure to harmful chemicals. Examples: Wood Dust: Can cause respiratory issues. Lacquers, Paints, and Solvents: Toxic fumes. Cleaning Agents: Corrosive or irritating. Adhesives and Glues: May cause skin irritation.

7. Chemical Hazards Definition: Hazards from exposure to harmful chemicals. Prevention: Use proper ventilation. Wear respiratory protection (masks). Store chemicals in labeled, sealed containers. Use gloves and protective clothing.

8. Biological Hazards Definition: Hazards from living organisms or biological materials. Examples: Wood Dust Allergies: Can cause asthma or allergic reactions. Mold and Fungi: From damp wood or materials. Insect Bites or Stings: From pests in the workshop.

9. Biological Hazards Definition: Hazards from living organisms or biological materials. Prevention: Keep the workshop dry and clean. Use air purifiers or HEPA filters. Avoid working with damp or moldy materials. Use insect repellent and protective clothing.

10. Ergonomic Hazards Definition: Hazards caused by poor posture, repetitive motion, or improper tool use. Examples: Musculoskeletal Disorders (MSDs): Back pain, carpal tunnel. Repetitive Strain Injury (RSI): From repetitive tasks. Poor Posture: From incorrect tool handling.

11. Ergonomic Hazards Definition: Hazards caused by poor posture, repetitive motion, or improper tool use. Prevention: Use ergonomic tools and equipment. Take regular breaks. Adjust workstations to fit the user. Use proper lifting techniques.

12. Electrical Hazards Definition: Hazards from faulty or improperly used electrical equipment. Examples: Electrical Shock: From exposed wires or faulty tools. Overloaded Circuits: From too many devices on one circuit. Fire Risk: From overheating or short circuits.

13. Electrical Hazards Definition: Hazards from faulty or improperly used electrical equipment. Prevention: Use grounded and certified tools. Inspect cords and plugs regularly. Avoid overloading outlets. Keep flammable materials away from electrical equipment.

14. Fire and Explosion Hazards Definition: Hazards from fire or explosion due to flammable materials or equipment. Examples: Flammable Materials: Wood, solvents, paint. Open Flames: From torches or welding. Electrical Sparks: From faulty wiring or tools.

15. Fire and Explosion Hazards Definition: Hazards from fire or explosion due to flammable materials or equipment. Prevention: Keep flammable materials away from heat sources. Use fire extinguishers and smoke detectors. Store flammable materials in approved containers. Follow fire safety protocols.

16. Psychological Hazards Definition: Hazards that affect mental health and well-being. Examples: Stress and Anxiety: From tight deadlines or high-pressure environments. Fatigue: From long hours or lack of rest. Workplace Bullying or Harassment: Prevention: Encourage a positive and supportive work environment.

17. Common Hazards in Specific Workshop Types Woodworking Workshop: Hazards: Wood dust, sharp tools, noise, fire risk. Prevention: Use dust collection systems, wear PPE, keep area clean. Metalworking Workshop: Hazards: Cutting tools, heat, sparks, chemical fumes. Prevention: Use guards, wear heat-resistant gloves, ensure proper ventilation.

18. Common Hazards in Specific Workshop Types Electrical Workshop: Hazards:   Electrical shock, fire, overloading. Prevention:   Use grounded tools, avoid overloading circuits, keep flammable materials away. Painting and Finishing Workshop: Hazards:   Toxic fumes, slip hazards, fire risk. Prevention:   Use ventilation, wear respirators, store materials safely.
