1. Objective 2.01 Recognize safety procedures and practices in a technological world

2. General Safety Rules

3. 1. Ask my teacher to approve all work that I plan to do. 2. Report all injuries, however small, immediately to my teacher. 3. Wear suitable eye protection when engaged in any activity where eye injury may happen. 4. Be sure clothes are safe and suitable for lab work. Remove or fasten any loose clothing and jewelry. Roll loose sleeves above the elbows. Keep hair away from equipment in operation (students with shoulder length hair must put-up or tie-back their hair.) 5. Observe rules concerning operator safety zones, and stand clear of zones in use.

4. General Safety Rules 6. Cooperate with my classmates in the safe operation of my lab. 7. Caution any student I see breaking a safety rule, and report it to the teacher. 8. Report to the teacher any equipment that does not seem to work properly. 9. Keep tools and materials clear from aisles and from projecting over the edge of workbenches. 10. Use a brush to clear away scrap materials and use a rag to clean oily areas.

5. General Safety Rules 11. Keep the floor clear of scraps and litter. 12. Do not work in the lab while under the influence of prescription or non-prescription drugs. 13. Immediately wipe up any liquid spilled on the floor. 14. Never operate equipment without passing a safety test and without knowing its safe use. 15. Place oily rags in a covered metal container and other combustible materials in a flammables cabinet.

6. General Safety Rules 16. Exercise care in handling large, heavy, or long pieces of material. 17. Know and practice procedures to follow in case of fire, tornado, hurricane or other disaster. 18. Maintain your judgment and behavior while working in the laboratory at all times. 19. Always make sure that computers, chairs, and desks are adjusted for safe use over time. 20. Take breaks every hour or so when working at computers for long periods of time.

7. Machine Safety Rules

8. Band Saw Safety Rules 1. Never get fingers close to the blade. 2. Use a push stick for close cuts. 3. Use relief cuts for long irregular cuts. 4. Always keep the blade guards in place. 5. Use a wood blade for wood and a metal blade for metal. 6. Keep the blade guard that protects the fingers and steadies the blade at a height that will not allow the “pinky” finger to slide under and contact the blade.

9. Band Saw Safety Rules 7. Check the blade tension with a piece of wood. 8. Check the blade tracking by observing the blade position in the guide blocks and bearing and by finally pulsing the machine. Check the throat plate clearance. 9. Do not reach behind the blade. 10. Never operate the machine without the guards in place. 11. Never stand to the right of the saw where the blade could come out if broken.

10. Belt and Disk Sander Safety Rules 1. Only use the down side of the disk sander. 2. Only abrade metal on a sander that has been used for sanding wood, then you may create a fire safety hazard because the metal will create sparks that can ignite wood dust. 3. Never dig corners of stock into the belt or disk. 4. Always use the support of the backstops or sanding tables.

11. Belt and Disk Sander Safety Rules 5. Do not abrade small stock; you could get your fingers caught by the disk or belt. 6. Do not bear down on the abrasives. This will help you to avoid tearing the belt or disk, and tearing could cause injury. 7. Before using the machine, make sure the belt is tracking properly and the disc is adhered well. 8. No more than one person may use the machine at a time. Often sanding machines have both a belt and disk, but only one person may use the entire machine at a time.

12. Drill Press Safety Rules 1. Set depth of cut to avoid drilling into the drill press table. 2. Generally, the softer the material you are drilling and the larger the twist drill or bit, then the slow the rpm should be set. The harder the material being cut and the smaller the twist drill, then the faster the rpm should be set. 3. On large floor model drill presses, set the rpm while it is running using the speed adjustment hand wheel. On many of the bench-top models, set the rpm while the drill press is stopped and unplugged using the pulley and belt. 4. Use a coolant when drilling metal. 5. Feed the drill so a steady stream of chips flow from the flutes of the twist drill. Metal should produce a continuous ribbon as its chip.

13. Drill Press Safety Rules 6. If chips become clogged in the flutes of twist drills, then remove the drill from the hole. 7. Clamp stock for specialty bits such as Forstner bits, speed bores, hole saws, expansion bits, etc. 8. Generally, use as slow a speed as possible for specialty bits, but make sure the cutter does not simply rub the stock and overheat. 9. Clamp irregular stock. 10. Always secure the drill in the chuck. 11. Always remove the chuck key before operation.

14. Computer and Ergonomic Safety Rules 1.Always make sure computers, chairs, and desks are adjusted for safe use over time. 2.Take breaks every hour or so when working at computers for long peroids of time.
