Auntie CeCe's Modern Workshop Technology Course: Shop Safety, Then and Now | Lesson 2

Lesson 2 of 13 in Auntie CeCe's Modern Workshop Technology Course, Part 1 (foundations). We learn to stay safe in the machine shop: the hierarchy of controls, guards and interlocks, entanglement, lockout/tagout, grinding wheel safety with a surface speed worked example, eye, ear and lung protection with a noise worked example, safety data sheets, and fire classes, comparing the classic shop rules with today's OSHA standards. In this lesson: Welcome Back to the Shop; The Hierarchy of Controls; Guards and Interlocks; Rotating Parts Grab; Lockout and Tagout; Grinding Wheel Safety; Worked Example: Wheel Speed; Eyes, Ears and Lungs; Worked Example: Noise; Chemicals and Safety Data Sheets; Fire in the Shop; Then and Now; Auntie's Recap. Course path: Part 1, foundations: 1 What is modern workshop technology · 2 Shop safety, then and now · 3 Metals and how we change them · 4 Measuring: calipers to CMMs · 5 Speeds, feeds and CNC Part 2, trade-exam build-up: 6 Casting · 7 Furnaces and induction heating · 8 Heat treatment and powder metallurgy · 9 Screw threads and angles · 10 Inspection: Taylor's principle to SPC · 11 Surface finish and machine alignment · 12 Grinding · 13 EDM, ECM, lapping, honing and crack detection The course follows the syllabus of a classic 1970s workshop technology textbook for technicians, rewritten from scratch and brought up to date with CNC, 3D printing, digital measuring and modern safety rules. There's a 3-question quiz at the end (pause and work it out), then the answers and the course path. This course is general education. Follow your instructor, the machine manual, OSHA rules and your shop's safety procedures for any real work. #WorkshopTechnology #AuntieCeCe #Machining #CNC
