2. Unit 8: Demonstrate personal safety measures in the use of tools, equipment, materials, and fire prevention techniques that are utilized in agricultural engineering facilities 681012

3. Safety awareness principles Safety awareness involves developing an environment or the state of being free from danger, risk or injury. The number one key factor to shop safety is the people who use the shop - Workers should always be trained in proper tool operations of shop tools and equipment - Workers should always pass a safety test before using the shop Safety awareness is being prepared since almost 50% of all farm related accidents involve working with machinery and equipment

4. Shop Safety Depends On Students Teacher Shop design

5. Principles of shop safety Keep the shop in an orderly manner to prevent tripping and related injuries Remove unnecessary hazards such as oily rags Minimize danger by making certain all machines and equipment have safety shields in place prior to and during operation Wear appropriate protective clothing and devices

6. Safety glasses or goggles Prevent eye injury from dust and flying objects

7. Leather steel-toed shoes Offers protection should items be dropped or fall on the individual’s feet

8. Ear plugs or ear muffs Are used to prevent hearing loss when the noise level exceeds 90dB (decibels)

10. Safety Shields For safety purposes, moving parts on machines should be shielded

11. Students Must stay in assigned areas when working in the shop Wear proper clothing Use or wear safety glasses at all times

12. Enhancements to Shop Safety Maintain a clean and orderly shop Proper instruction Machines adjusted properly

13. Shop Accidents Electrical contact or shock is an example of a shop accident

14. Noise Duration Length of time a person is exposed to sound Noise of 90 decibels can damage an individual hearing

16. CPR Is the first aid technique use to provide oxygen to the body and circulate blood

17. Farm accidents The most common accident among farm workers is farm machinery accidents

19. Color Coding Paint areas in the shop with specific colors to warn or alert workers or individuals of specific dangers or hazards provides information to help individuals react quickly in an emergency in the shop

20. The Shop Color Coding System Was developed by: American Society of Agricultural Engineers, they were the first organization to publish a shop safety color coding system for agricultural shops, Safety Committee of the American Vocational Association, and National Safety Council

21. Orange Orange = warning or hazard This color is used to designate dangerous (hazardous) moving parts of equipment that may cut or otherwise injure Use as the background for electrical switches, levers and controls on shop equipment

22. Yellow Yellow = caution This color used to designate caution Is the safety color used to identify wheels, levers, or knobs that control or adjust shop equipment or machines

23. Red Red = danger This color is used to designate the location of fire fighting equipment and safety switches Also to identify areas or items of danger or emergency equipment such as safety switches and fire extinguishers

24. Green Green = safety This color is used to designate the location of safety and first aid equipment and medical practice

25. Blue Blue = information This color is used to designate caution against starting equipment that is defective or out of order is also used on signs as “out of order” to identify broken shop equipment that does not work properly

26. Ivory This color is used to reflect light and show the way

27. White This color is used to mark work areas around objects in the shop

28. Dust Mask Reduces hazards of breathing dust and spray paint

29. OSHA Stands for the Occupational Safety and Health Administration

30. Leather gloves and shoes Leather gloves used when doing metalworking Leather footwear is a type of footwear that is strong and durable when working in the agricultural shop

31. Earplugs Are worn when the: noise intensity is high Noise frequency is high or when noise duration is long

32. Terms related to potential hearing damage Noise intensity Noise frequency Noise duration

33. Coveralls Best item of protective clothing for agricultural workers

34. Hearing Protection Should be used when working with a radial arm saw, planer, or router

35. Protective Clothing Should be fire resistant Fit properly, and Be clean

36. Hard Hats Are made of lightweight, impact resistant material used to protect individuals from head injuries when working on construction jobs

37. Eye Protection Provides protection when using chemicals, When using grinding tools or machines, When using welding equipment and tools

38. Classes of fires Class A fire: are ordinary combustibles which include wood, papers, leaves, rags and trash Class B fire: are flammable liquids which include fuels, greases, paints, and other liquids Class C fire: involves electrical equipment and wiring which involve the presence of electricity (electrical fire) Class D fire: combustible metals are metals that burn. Burning metals are very difficult to extinguish

39. Fire Extinguisher information Know the kind of fire extinguisher that is used for different kinds of fires prior to the fire. For example: Class A fires are extinguish using Class A fire extinguishers that uses water or gas pressure to control ordinary combustible materials Know the placement of fire extinguishers in the shop so that time is not wasted looking for the extinguisher if a fire occurs and the fire can be quickly extinguish. Fire extinguishers should be hung on walls within easy reach in areas of shops where fires are most likely to occur, this insures that a fire extinguisher will be available if it is needed

40. Using the fire extinguisher -Generally, when using a fire extinguisher, it is held upright, the ring pin is pulled, and the lever is pressed -The nozzle of the extinguisher is directed toward the base of the fire to discharge the extinguisher contents -The quickest method of extinguishing a fire with a fire extinguisher is to hit the base of the flame with the fire extinguishing material -When the user knows what type of fire a fire extinguisher will control prior to a fire occurring, fires can be controlled safety

41. Types of fire extinguishers Class A fire extinguisher may consist of a dry chemical material or water with a pump or gas pressure to extinguish Class A fires, Class B/C fire extinguishers may use carbon dioxide gas (CO2) to extinguish Class B and C fires Class A, B, and C extinguishers may use a dry chemical material to extinguish Class A, B, or C fires

42. Standardized symbols on fire extinguishers Class A fire extinguisher: will have a Green Triangle decal — for ordinary combustibles Class B fire extinguisher: will have a Red Square decal --- flammable liquids Class C fire extinguisher: will have a Blue Circle decal --- electrical equipment Class D fire extinguisher: Yellow star decal ---- combustible metals

43. Fire Triangle components Fuel: any combustible material that will burn, example: oily rags, sawdust, paper, etc Heat: most materials will burn if they are made hot enough in the presence of oxygen Oxygen: Gas in the atmosphere that is not a fuel, but must be present for fuels to burn

44. Fire Prevention Take away one of the components of the fire triangle and you cannot start a fire or a existing fire will will stop Safe storage of fuels is the easiest fire prevent technique Clean shop facilities also decrease the chance of a fire

45. Smothering fire technique Is used on a person whose clothes are on fire Wrap the person in the firev blanket to cut the oxygen off to the clothing on fire
