NOTE

SAFE WORKING HABITS, INSTRUMENTS, EQUIPMENTS AND MATERIALS. CARE OF EQUIPMENTS

Safe working habits in a technical drawing workshop are crucial for maintaining a productive and hazard-free environment. The following are some essential practices:

  1. Maintain good posture: Sit or stand in a comfortable and ergonomic position to prevent strain on your back, neck, and wrists during long drawing sessions.
  2. Use proper lighting: Ensure adequate lighting to avoid eye strain and to accurately see details on the drawing surface.
  3. Handle drawing tools with care: Sharp instruments such as compasses, rulers, and drafting pencils should be handled carefully to prevent injury. Always cap or cover sharp points when not in use.
  4. Keep work areas clean: Organize drawing tools and materials neatly to prevent clutter and make it easier to find what you need. Clean drawing surfaces regularly to remove dust and debris.
  5. Avoid distractions: Focus on your work and avoid distractions such as loud noises or conversations that could lead to errors or accidents.
  6. Take breaks: Give yourself regular breaks to rest your eyes and prevent fatigue during extended drawing sessions.
  7. Use ventilation: If using materials such as ink or solvents, ensure proper ventilation to prevent exposure to fumes.

Instruments, equipment, and materials

 commonly used in technical drawing workshops include:

1. Drawing board: A flat, smooth surface mounted on a stand, used as a base for drawing paper or tracing sheets.

2. Drafting table: An adjustable table specifically designed for technical drawing, typically equipped with a drafting machine for precise measurements and angles.

3. Drawing paper: High-quality paper suitable for pencil, ink, or marker drawings. Different weights and textures are available depending on the intended use.

4. Drawing tools: Compasses, rulers, T-squares, triangles, protractors, and templates for accurate measurements, angles, and geometric shapes.

5. Writing instruments: Pencils, technical pens, markers, and ink pens for creating lines of various thicknesses and styles.

6. Erasers and correction tools: Kneaded erasers, eraser shields, and correction fluid for removing mistakes and making corrections.

7. Drawing aids: French curves, ellipse guides, and stencils for drawing curves, arcs, and other complex shapes.

Care of drawing equipment

  1. Wipe down drafting instruments with a clean cloth to remove dust and debris, and keep them in a protective case or pouch when not in use.
  2. Check drawing tools for signs of wear or damage, such as bent rulers or worn-down pencil points, and replace them as needed to ensure accurate and precise drawings.
  3. Keep drawing tools and materials in a clean, dry environment away from moisture and direct sunlight to prevent damage or deterioration.
  4. Avoid dropping or mishandling drawing tools, as this can lead to damage or deformation that affects their performance.
  5. Refer to the manufacturer's guidelines for specific care instructions for each drawing tool or equipment, such as cleaning methods or storage recommendations.
