Currently the high school is the oldest high, school in the district, over 40 years old, and is two different classrooms that house all the classes in the department . The facilities are old and outdated and with the new school, all classrooms will be state-of-the-art and be built to teach in for another 40 years .My project will give the department a design that will be used for ideas for construction. and give the teachers an equipment list made from the design. They will know where each machine should be placed in order to have the most available space in the classrooms and keep the classroom safe for students .Designing the shop before it is built gives the teacher a great advantage of knowing where machines will be placed and how much walking room will be available for students and faculty to move around so things are not placed too tightly together with no room to work . This design will also be approved by the department head and will give the teachers an idea of what the shop will look like when completed.LITERATURE REVIEWThe agricultural shop will be one that serves multiple purposes at the high school . It will teach students everything from what to call tools to advanced classes in welding, fabrication and design . A shop provides a place to do anything that involves using machinery to design and build a product used by the student . Technical and vocational skills are becoming more important in hard times because people cannot afford to pay someone to fix everything that breaks . The shop will also provide a central location to store and keep track of tools used throughout classes taken . With the new shop, the high school agriculture department will have the ability to fix and build almost anything they desire .Shop SetupImportant aspects when planning a shop are space requirements, equipment layout and access to all parts of the shop, storage, electrical, ventilation and other amenities needed .The size of the shop will regulate the number of machines that will be able to be purchased and placed . An outdoor area will also provide for a bigger working area other than just inside the shop . Tools and equipment need to be in a place easy to reach and convenient to make it easier to work in the shop Setup The electrical aspect of the shop is going to be very intricate and carefully planned . An electrical service of 200 amps, 240 volts is the minimum recommended electrical for a shop says Hofman and Hellevang . This service will provide for the machines and power tools that will be running . Use separate circuits for motors over horsepower and no more than two motors on a circuit . The welders need a 50 amp or larger 240 volt outlet and since there is many welders there will be many 240 outlets . Ground fault interrupters are needed around anywhere that can get wet or along the outside of the building . These outlets prevent the user from electrocuting themselves . Lighting in the shop will be planned to provide enough lighting throughout the shop so work can be done anytime day or night . Electricians and electrical inspectors will inspect the wiring before anything is finalized . Ventilation of the shop will be planned and the welding area will need its own exhaust hood to provide adequate exhaust of the welding gases and fumes created from welding . Tool benches and part storage is very important to keep tools organized and easy to access . An easy way of organizing tools is hanging them on a wallboard and outlining the individual tools . This way you can glance at a board and see what is missing very quick . Grouping alike tools will make finding tools easier when looking for a specific tool . Plywood or pegboard can be used to hang the tools on the wall . These will provide enough thickness to screw screws into or have nails to hang the tools on . Workbenches should be 34 to 38 inches high and adjusted to the principal users height . The bench depth is normally 24 to 30 inches and should be anchored securely (Hofman, Hellevang) . These benches will be covered with steel for durability The large, freestanding tools should be placed near the welding area and fabrication part of the shop . They cannot be placed in the corner because it limits the ability to work on large pieces of material . These tools should have stable bases but should not be anchored to the floor to provide flexibility of the machine placement when dealing with an oversized piece of material that does not fit within the space boundaries .There will be many storage areas around the shop and will be organized by style of material or tool . They will have shelving and drawers to be used for similar parts and materials . These areas will need to be kept clean and organized, so every day the students will need to clean and put everything away where they got it from .SafetyShop safety is the number one priority when working in the shop . Especially at a high school level, rules have to be created and followed . The hazards are special and require special safety considerations . The ASABE standards article talk about having a safety color code for educational and training laboratories . It discusses having color coded areas so people know what kind of hazards or dangers are present in that area . It says the different tools and hazards that should be marked and what colors should be used for those areas . These colors will tell the people using the tools exactly what to watch for not to get hurt .Shop SafetyFollow these guidelines for general shop safety:1. Know the hazards associated with your work . Be sure you are fully educated onthe proper use and operation of any tool before beginning a job .2. Always wear appropriate safety gear and protective clothing .3. Wear nitride gloves when cleaning with degreasers or ferric chloride (latex gloves do not provide adequate protection . )4. Ensure that there is adequate ventilation to prevent exposure from vapors of glues, lacquers, paints, and from dust and fumes .5. Maintain good housekeeping standards . Keep the work area free from slipping/tripping hazards (oil, cords, debris, etc . ) Clean all spills immediately Remove sawdust, wood chips, and metal chips regularlyIt is recommended that electrical cords pull down from an overhead pulley rather than lying on the floor .6. Leave tool and equipment guards in place .7. Know where fire extinguishers are located and how to us them .8. Make sure all tools and equipment are properly grounded and that cords are in good condition . Double insulated tools or those with three wire cords are essential for safety Use extension cords that are large enough for the load and distance.9. Secure all compressed gas cylinders . Never use compressed gas to clean clothing or skin .10. Always use flashback arresters on cutting/welding torches .11. Take precautions against heat stroke and heat exhaustion .12. Wear infrared safety goggles when appropriate .General hand tool safety1. Wear safety glasses whenever you hammer or cut, especially when working with surfaces that chip or splinter .2. Do not use a screwdriver as a chisel . The tool can slip and cause a deep puncture wound .3. Do not use a chisel as a screwdriver . The tip of the chisel may break and cause an injury .4. Do not use a knife as a screwdriver . The blade can snap and cause an injury .5. Never carry a screwdriver or chisel in your pocket . If you fall, the tool could cause a serious injury . Instead, use a tool belt .6. Replace loose, splintered, or cracked handles . Loose hammer, axe, or maul heads can fly off defective handles .7. Use the proper wrench to tighten or loosen nuts . Pliers can chew the corners off a nut .8. When using a chisel, always chip or cut away from yourself .9. Do not use a wrench if the jaws are sprung .10. Do not use impact tools, such as chisels, wedges, or drift punches if their heads are mushroom shaped . The heads may shatter upon impact .11. Direct saw blades, knives, and other tools away from aisle areas and other employees .12. Keep knives and scissors sharp . Dull tools are more dangerous than sharp tools .13. Iron and steel hand tools may cause sparks, which are hazardous around flammable substances . Use spark-resistant tools made from brass, plastic, aluminum, or wood when working around flammable hazards .Tool StorageImproper tool storage is responsible for many shop accidents . Follow these guidelines to ensure proper tool storage:1. Have a specific place for each tool .2. Do not place unguarded cutting tools in a drawer . Many hand injuries are caused by rummaging through drawers that contain a jumbled assortment of sharp-edged tools .3. Store knives or chisels in their scabbards .4. Hang saws with the blades away from someones reach .5. Provide sturdy hooks to hang tools on .6. Store heavy tools, such as axes and sledges, with the heavy end down Power Tool Safety1. Use the correct tool for the job . Do not use a tool or an attachment for something it was not designed to do .2. Select the correct bit, blade, cutter, or grinder wheel for the material at hand . This precaution will reduce the chance for an accident and improve the quality of your work .3. Keep all guards in place . Cover exposed belts, pulleys, gears, and shafts that could cause injury .4. Always operate tools at the correct speed for the job at hand . Working too slowly can cause an accident just as easily as working too fast .5. Watch your work when operating power tools . Stop working if something distracts you .6. Do not rely on strength to perform an operation . The correct tool, blade, and method should not require excessive force . If undue force is necessary, you may be using the wrong tool or have a dull blade .7. Before clearing jams or blockages on power tools, disconnect from power source . Do not use your hand to clear jams or blockages, use an appropriate tool .8. Never reach over equipment while it is running .9. Never disable or tamper with safety releases or other automatic switches .10. When the chance for operator injury is great, use a push stick to move material through a machine .11. Disconnect power tools before performing maintenance or changing components .12. Keep a firm grip on portable power tools . These tools tend to “get away“ from operators and can be difficult to control .13. Never leave chuck key in chuck .14. Keep bystanders away from moving machinery .15. Do not operate power tools when you are sick, fatigued, or taking strong medication .16. When possible, secure work pieces with a clamp or vise to free the hands and minimize the chance of injury . Use a jig for pieces that are unstable or do not lie flat .Welding and CuttingWelding and cutting are two forms of hot metal work that require special safety considerations . Unless they are done in a designated shop area, welding and cutting are strictly prohibited without proper authorization . Before conducting welding or cutting operations, inspect your equipment for the following:1. Welding leads must be completely insulated and in good condition .2. Cutting tools must be leak-free and equipped with proper fittings, gauges, regulators, and flashback devices .3. Oxygen and acetylene tanks must be secured in a safe place . In addition, follow these guidelines for most welding and cutting procedures:1. Conduct welding and cutting operations in a designated area free from flammable materials . When welding or cutting is necessary in an undesignated or hazardous area, have someone nearby act as a fire attendant . 2. Periodically check welding and cutting areas for combustible atmospheres . 3. Take care to prevent sparks from starting a fire . 4. Remove unused gas cylinders from the welding and cutting area .5. Keep hoses out of doorways and away from other people . A flattened hose can cause a flashback .6. Mark hot metal with a sign or other warning when welding or cutting operations are complete .PROCEDURES AND METHODSProcedures to design the shop start with knowing the important factors that will influence the design. Such as square footage of the building, square footage of areas which will be used for storage, working areas, learning areas, office areas, cleanup areas, and all other areas which will be built. The next step is to find out what the department wants in the building. What type of facilities are needed, what type of facilities are wanted and what other tools are needed to be included in the design. Having the current building acting as a building block/basis for the new building, all facilities in the current building need to be included as a minimum for the new building.
