- Usage: For correcting mistakes.
- Types: rubber, kneaded, and vinyl erasers.
Health, Safety, and Environment (HSE) Measures
- Workspace Organization
- Keep the drawing area clean and free of clutter.
- Ensure proper lighting to avoid eye strain.
- Instrument Safety
- Handle sharp instruments like compasses and cutters carefully.
- Store instruments properly to avoid accidents.
- Material Safety
- Use non-toxic materials when possible.
- Ensure proper ventilation when using adhesives or markers.
- Personal Protective Equipment (PPE)
- Use safety goggles if necessary.
- Wear gloves when handling chemicals or sharp tools.
- Ergonomics
- Maintain a comfortable posture while drawing.
- Take breaks to avoid repetitive strain injuries.
Conclusion
This lab introduces essential drawing instruments and emphasizes the importance of adhering to HSE measures while engaging in geometrical drawing activities. Proper tool usage and safety practices are crucial for effective and safe learning experiences.
