The safety and hygiene in technical drawing are essential because they seek that projects are free of dirt and have a flawless presentation. It is imperative that a technical drafting professional's workplace is free of ink stains, dust, or eraser residue.
You must always be careful that the work elements such as squares, compass, rulers, bevel are clean since they are the elements that will be in contact with the surface of the drawings.
Working safely and hygienically can involve changes in how art materials are selected and how they are handled. Cleanliness and neatness in drawing work are very important requirements. Definitely the hallmark of excellence for any technical draftsman.
Technical drawing is important because it helps companies to visualize a concept with which they can easily communicate a physical element for their production.
Companies use technical drawings for item prototypes and the final version for production.
These drawings must be detailed and follow the specifications required in industry, such as engineering. Technical drawings are often made using computer software such as SolidWorks or AutoCAD, and they can be two-dimensional or three-dimensional drawings.
Engineers who make these drawings typically follow a process that involves developing a drawing in the software, analyzing the structure of the model, creating a virtual prototype, testing the prototype to make sure it works properly and meets health and safety specifications, to then perform a final analysis.
Safety and hygiene standards in technical drawing
- Drawing materials can be: Toxic, can cause physical injury by inhalation, ingestion or by contact with the skin. They can be irritating, cause inflammation of the skin, eyes, mucous membranes or pain.
- Do not eat or drink near the work area (to avoid accidental ingestion).
3. Become familiar with substances that are dangerous.
4. Hands must be kept clean at all times during work.
5. Wash your hands thoroughly after working with baby oil, soap and water, 6. Keep the work area clean and try to keep it in order.
7. Ask your doctor if you are taking medication or are pregnant about what precautions you should take regarding working instruments such as ink, which can affect health in some way.
8. All drawing instruments should be kept clean with a cloth or towel.
9. Identify the location of the fire extinguishers and the first aid box.
10. Notify your boss of any health conditions or medications that may affect your job.
11. Always have adequate ventilation.
12. When using liquid drawing media like ink try to use alcohol-based ones as they are less toxic.
13. Never paint your body with markers or drawing inks. Body painting should be done with cosmetic colors.
14. Dangers: Drawing inks are generally water-based but there are some solvents that generally contain solvents like xylene so you should take precautions.
15. Permanent felt tip markers used in design or graphic arts contain solvents. Xylene is a highly toxic aromatic compound
16. Newer markers often contain propyl alcohol which, although less toxic, is irritating to the eyes, nose, and throat. The biggest risk of using permanent markers is using them at close range.
17. Try not to oil the compass.
18. Always try to keep the eraser free of ink and graphite.
19. Have a brush to clean up the remnants of the eraser.
20. Never submit a project with small holes caused by the use of the compass.
21. Always try to have natural light in your workplace
22. When using the pencil sharpener, make sure your hands are clean and free of any traces of graphite.
23. Never put your work objects in your mouth.
24. The pencil must always be kept sharp and must be used properly. It should be kept away from the drawing sheet and other instruments.
25. Avoid direct hand contact with the drawing sheet.
26. Rubbing or erasing should be done correctly with a soft eraser.
27. If you suffer from allergies or have sensitive eyes, you should always try to protect your eyes with lenses.
28.If long hair is worn, try to collect it so that it does not interfere with the process of creating the drawing.
29. Every 30 minutes try to rest your eyes for 10 minutes.
30. Ink containers and all working instruments should be kept at a safe distance from the technical drawing work in progress.
31. Glasses should never be left near the project that is being carried out.
32. You should try to have the least contact with the drawing you are working on.
33. You should never lean your elbows or your body on the drawing project in progress.
34. Always try that the entrance of natural light or the lamp that you use to have a light source is on the left.
35. The paper you are working on must always be on the left side of the board and if you are left-handed, on the right side.
36. Always keep your drawings protected in a cylinder or folder to prevent them from getting dirty.
37. As for the drawing lines, you should always try to make sure that they are sharp, and that they are never blurred.
38. When using a compass, its lead should always be sharp.
39. Before submitting your project, seek a second opinion from a colleague who will give you their point of view regarding the hygiene of your drawing.
40. After finishing your project, clean your work area, your instruments, and always keep your area spotless.
