2. Shop Safety Awareness and Principles for Safety  Of all farm related accidents, nearly 50% involve working with machinery  Safety involves developing an environment free from danger, risk, or injury  Number one key to shop safety is the people who use the shop  Those who work in a shop should always:  Be trained in safe and proper tool operations  Pass a safety test prior to using the shop

3. Shop Safety Awareness and Principles for 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 sure all machines have safety shields in place prior to and during operation

4. Shop Safety Awareness and Principles for Safety  Wear appropriate personal protective clothing and devices:  Safety glasses or goggles should always be worn to prevent eye injury from dust and flying objects  Leather steel-toed shoes offer protection from items dropped or falling on the feet  Ear protection (plugs or muffs) can prevent hearing loss when the noise level exceeds 90 dB (decibels)  Other safety clothing may be required for certain work such as welding

6. Safety Color Coding in the Agricultural Mechanics Shop  Development of Safety Color Coding  National organizations worked together to develop the system  The American Society of Agricultural Engineers and the Safety Committee of the American Vocational Association published the code  Color coding alerts people to dangers and hazards, provides information to help on reacting quickly in an emergency  Each color or combination of colors conveys a special message based on a standard code

7. Basic Safety Code Colors  RED  Identifies areas of danger  Used on safety switches and fire extinguishers  Red = Danger  ORANGE  Designates machine hazards, such as edges and openings  Also used as background for electrical switches, levers and controls  Orange = Warning

8. Basic Safety Code Colors  YELLOW  Identifies wheels, levers, and knobs that adjust or control machines  Yellow = Caution  BLUE  Used on signs such as “Out of Order” to identify broken shop equipment that does not work or does not work properly  Blue = Information  GREEN  Indicates the presence of first aid and safety equipment  Green = Safety

9. Fire Hazards in the Agricultural Mechanics Shop  The Fire Triangle – components necessary for a fire:  Fuel – any combustible material that will burn  Oily rags, sawdust, paper, ect.  Heat – most materials burn if they are made hot enough  Oxygen (O) – gas in the atmosphere that is not a fuel, but must be present for fuels to burn

10. Fire Hazards in the Agricultural Mechanics Shop  Fire Prevention  Take away one of the components of the fire triangle and fire will not start or will stop if already started  What is one thing we can take away from the triangle to prevent a fire?  Safe storage of fuels or combustible materials is the easiest fire prevention strategy  Store fuels in approved containers  Clean shop facilities also decrease the chance of fire and injury

11. Extinguishing Fires  Fire Extinguishers  Know the kind of fire extinguisher that is used for different kinds of fires prior to the fire  Example: Class A Fire Extinguishers use water to control ordinary combustibles  Know the placement of fire extinguishers so that time is not taken looking for the extinguisher if a fire occurs  Fire Extinguishers should be hung on walls within easy reach in areas where fires would most likely occur  Where is our fire extinguisher in the classroom?  Why do you think it is located there?  Know how to use the fire extinguisher

13. Extinguishing Fires  Using a Fire Extinguisher:  Generally, extinguishers are held upright  The ring is pulled  Lever is pressed  Nozzle of the extinguisher is directed toward the base of the fire to discharge the extinguisher  Other examples of extinguishing fires:  Wrapping a person in a blanket whose clothes are on fire to eliminate oxygen from getting to the fire  Cooling with water from a hose or bucket
