In a subject such as this, dealing largely with appliances and fittings in daily use in the home and other buildings, the student has excellent opportunities of combining practical investigations with book knowledge. Despite daily familiarity, the average adult will give surprising figures when asked about the height of an ordinary W.C. seat or dimensions of an average lavatory basin. Therefore, students should sketch these familiar objects from actual observation using a two-foot rule or tape measure and a sketch-book in hand. Information gathered this way and coordinated with textbook statements will make a lasting impression on their minds.
Some examples of sanitary work are not as easy to see daily, but time spent lifting off manhole covers of drains, visiting building sites when drains are being laid, watching fittings being fixed, and inspecting water supply and waste pipes is well repaid. Visits to museums and showrooms can provide practical help in most large towns.
The ability to sketch freely or with simple instruments like setsquares accurately showing proportions without scale is an asset. Architectural students generally have a natural aptitude for drawing, but others may need to study sanitation without this skill. Sketches should aim at essential principles of design and keep general proportions as accurate as possible even when drawn freehand.
Using colored pencils or crayons can help make sketches clear during study or revision. The use of vertical lines or water levels as guide lines helps in sketching symmetrical or asymmetrical objects accurately. British Standard Designs are important for standardizing specifications and reducing the number of types manufacturers need to produce, simplifying work for builders and architects.
The historical development of sanitary fittings is covered extensively because many readers will inspect and maintain older buildings with outdated fittings.
Key Takeaways
- Combining practical observations with book knowledge enhances understanding of sanitation practices.
- Sketching from actual observation is crucial for accurate and lasting impressions.
- Visiting sanitary museums, showrooms, or building sites provides valuable hands-on experience.
Practical Tips
- Carry a sketchbook and measuring tools to observe and record dimensions accurately.
- Use colored pencils or crayons during study sessions to enhance clarity of sketches.
- Refer to British Standard Specifications for standardized designs in sanitation fittings.
Warnings & Risks
- Avoid relying solely on memory when sketching familiar objects; always measure and observe.
- Be cautious while lifting manhole covers as it can be dangerous without proper safety measures.
Modern Application
While the chapter focuses on historical methods of studying sanitation, its emphasis on hands-on learning remains relevant today. Modern survival preparedness benefits from understanding how to accurately assess and maintain plumbing systems in older buildings, which often require knowledge of outdated fittings and practices.
Frequently Asked Questions
Q: What are some practical ways to study sanitation according to this chapter?
The chapter suggests combining book learning with hands-on observation by sketching familiar objects from actual measurements rather than relying on memory alone.
Q: Why is it important to visit sanitary museums and showrooms during studies?
Visiting these places provides practical help in understanding the latest designs and fittings, which can be beneficial for both study and professional practice.
Q: How does the chapter recommend using colored pencils or crayons?
Using colored pencils or crayons during sketching sessions can enhance clarity and make it easier to understand sketches later on.
