Keep guards in place, remove chuck key before starting, and stop the machine before cleaning or measuring. Maintain a clean, dry floor, know emergency stops and first-aid locations, and report all accidents. ## Answer Workshop safety means working in a way that prevents injury to people and damage to machines. The main rules are grouped below. #### Personal safety - Wear close-fitting overalls or an apron, with sleeves buttoned or rolled up; no loose clothes, ties, rings, watches or scarves near rotating parts. - Tie long hair back or cover it with a cap. - Wear safety shoes, goggles or a face shield (grinding, chipping, welding), gloves (welding, hot work) and ear protection where noise is high. - Never wear gloves while working near a rotating drill or lathe spindle. #### Machine and tool safety - Learn the machine and its emergency stop before starting it; operate it only with the instructor's permission. - Keep guards fitted over belts, gears, chucks and grinding wheels; never remove them. - Clamp the job and tool firmly; remove the chuck key before starting the lathe. - Stop the machine before measuring, cleaning, oiling or changing speed. - Do not remove chips with bare hands; use a brush or hook. Do not use compressed air to clean clothes. - Use sharp, undamaged tools with properly fitted handles. Grind off mushroomed chisel heads. #### Housekeeping and general rules - Keep the floor clean, dry and free from oil, chips and obstructions; keep passages clear. - Store tools in their proper place; keep heavy items low and stable. - No running, joking or distracting a person who is operating a machine. - Know the position of the first-aid box, fire extinguishers and exits. #### Electrical and emergency - Check the earthing of machines; do not touch switches with wet hands; report damaged cables. - Report every accident, however small, and give first aid at once. - Keep flammable liquids in closed metal containers away from sparks. ## Check yourself The answer's key points as multiple-choice questions, with the correct option and why. 1. Why must gloves NOT be worn while working near a rotating drill or lathe spindle? A. They reduce grip on the job B. They can be caught by the rotating part and pull the hand in C. They get dirty with cutting oil D. They make measuring impossible Answer: B. Loose items such as gloves can be caught by rotating parts and drag the hand in, so they are avoided near drills and lathe spindles. (Key point: Gloves near rotating parts) 2. Which action is required before starting a lathe? A. Remove the chuck key B. Remove the guards for a clear view C. Loosen the job slightly D. Oil the spindle while it runs Answer: A. A chuck key left in the chuck can be thrown out at high speed, so it is removed before starting. (Key point: Before starting the lathe) 3. When should the machine be stopped? A. Only at the end of the shift B. Only when the instructor is absent C. Before measuring, cleaning, oiling or changing speed D. Only when the job is finished Answer: C. Measuring, cleaning, oiling and changing speed are done with the machine stopped to avoid contact with moving parts. (Key point: Stopping before adjustment) 4. What is the correct way to remove chips from a machine? A. Blow them off with compressed air B. Sweep them with bare hands C. Use a brush or hook D. Wipe them with a loose cloth while running Answer: C. Chips are sharp and hot, so use a brush or hook; bare hands and compressed air are unsafe. (Key point: Chip removal) ## Related in Workshop Technology - [Hacksaw parts and blade selection](https://www.bctengineer.com/question.md?key=semester_2%2Fworkshop_technology%3Ahacksaw-parts-blade-pitch) — Workshop Technology, chapter 2 - [Classes of fire and fire extinguishers](https://www.bctengineer.com/question.md?key=semester_2%2Fworkshop_technology%3Afire-classes-extinguishers) — Workshop Technology, chapter 1 - [Shaper machining time calculation](https://www.bctengineer.com/question.md?key=semester_2%2Fworkshop_technology%3Ashaper-machining-time-numerical) — Workshop Technology, chapter 6 - [Gear manufacturing and simple indexing](https://www.bctengineer.com/question.md?key=semester_2%2Fworkshop_technology%3Agear-milling-indexing-numerical) — Workshop Technology, chapter 11 ## Related in other subjects - [Basic electrical safety rules and regulations](https://www.bctengineer.com/question.md?key=semester_8%2Fhigh_voltage_engineering%3Aelectrical-safety-rules) — High Voltage Engineering, chapter 2 - [Short note: Fire regulations and site safety](https://www.bctengineer.com/question.md?key=semester_8%2Fconstruction_management%3Afire-regulations-safety-site) — Construction Management, chapter 11 - [Short note: Electrical safety rules](https://www.bctengineer.com/question.md?key=semester_1%2Fbasic_electrical_and_electronics_engineering%3Ashort-note-electrical-safety-rules) — Basic Electrical and Electronics Engineering, chapter 4, asked 2× - [General electrical rules for installation and wiring](https://www.bctengineer.com/question.md?key=semester_6%2Findustrial_power_distribution_and_illumination%3Aelectrical-rules-installation) — Industrial Power Distribution and Illumination, chapter 1, asked 3×
