Making Safety a TOP Priority Ag Mechanics II
Safety IS… • Safety is when workers are free from danger, risk, or injury • Safety in agricultural mechanics shops depends mostly on the people who use the shop • The major cause of accidents are unsafe actions by people and unsafe working conditions
The Basics • Follow the 12 safety rules listed on the handout. • The best protective clothing for agricultural workers is coveralls • Minimum protection is safety glasses • Prevention • Protective Devices • MSDS sheets
In the Beginning… • National organizations worked together to determine colors • American Society of Agricultural Engineers and the Safety Committee Of the American Vocational Association published a code • Occupational Safety and Health Administration
To be safe and efficient, a shop must be large enough to have a reasonable space for each person working in the shop • A clean and well organized shop decreases the chance of accidents • An approved flammable materials cabinet improves shop safety by providing a safe place to store those materials and by automatically closing if there is a fire
Tools and materials should be put in their proper places to save time and prevent accidents • To help prevent back injuries, heavy objects should be lifted with the legs and not the back • Loose clothing, jewelry, and long hair can cause serious injury by getting caught in saws, drills, and other equipment with rotating or turning parts
Causes of Accidents • Farm Machienery--------44%--almost half • Drowning------------------12% • Hit by objects--------------9% • Electrical current----------7% • Firearms--------------------5% • Falls-------------------------5% • Others----------------------18% Includes burns, animals, poisons etc.
Different Types of Eye Protection • Safety Glasses • Safety Goggles • Face Shield • Welding Helmet
Always wear the appropriate eye protection Safety glasses will ALWAYS be worn Eye Protection

Review What color means danger? What is a dangerous level of noise? What is the best protective measure for someone in the shop setting?
Noise Levels • Unit of measure for sound is decibels • Hearing loss caused by level and time exposed • 90 decibels or higher is dangerous
How to extinguish a FIRE • http://www.fireextinguisher.com/ • P pull the pin • A aim at the base of the fire • S squeeze the operating lever • S sweep from side to side
Class A- is caused by ordinary combustibles such as wood or paper. The symbol is a green triangle • Class B- is caused by flammable liquids such as gasoline or solvents. The symbol is a red square
Class C- is caused by electricity. The symbol is a blue circle • Class D- is caused by combustible metals. The symbol is a yellow star • Class K- Fires in cooking oils and greases such as animal fats and vegetable fats
Types of Extinguishers • Water is used for type A • Carbon monoxide (CO2) used for Class B and C fires • Dry Chemical is used for Class A, B, and C fires • Wet chemical is used on Class K
Types of Extinguishers • Only Class D extinguishers will work on burning metals • Extinguishers should be located 3 ½ to 5 feet above the floor so that they will be easy to reach
Hand Tool Safety • Use the right SIZE and TYPE of tool for the job • Follow the correct procedure for using every tool • Keep cutting tools sharp and in good condition
Don’t work with oily or greasy hand tools • Handle sharp or pointed tools with care • Always carry sharp or pointed tools with the point down
Never carry tools in your pocket • Don’t use tools that are loose or cracked • Chisels or punches with mushroomed heads should be ground smooth
Don’t use screwdrivers as chisels or pry bars • Don’t use a “cheater” with a wrench • Don’t use a file without a handle
After using a tool, clean it and return it to its proper place • If anything breaks or malfunctions, report it to your instructor at once • Never place tools & materials where they hang on the edge of the table
Don’t use tools for things they weren’t meant for Cut away from yourself when using sharp tools Don’t pry or hammer with file.
Hammers • Hold hammer near the end away from the hammer to improve accuracy and leverage • Large nails require the use of a heavier hammer than small nails • Using nails to fasten wood is fast, but is the weakest method
Hammers • Many types of nails are available. The correct type should be used for the job. Common nails are used most in construction, but finishing nails should be used when the head needs only be set below the surface of the wood
Measuring and Marking Tools • “Measure twice, cut once “ is a good rule to follow to reduce the amount of wasted materials and time • Most measuring tools are divided into 1/16” marks. The shortest lines on the rule a usually 1/16th measurements
Measuring and Marking Tools • The string of a chalk line should be stretched tight and snapped in the middle to mark an accurate long straight line • A scratch awl, file, or scriber can be used to mark a scratch on metal • Soapstone can be used to mark metal without leaving a permanent scratch
Metal Cutting Tools • Files- since files only cut on the forward stroke, pressure should be reduced on the backstroke • Hacksaws- Teeth should be pointed away from the handle because most of the cutting is done on the forward strokes • Taps and Dies- When used to cut metal, oil should be used for lubrication
Use the correct size and type for the job A heavy duty screwdriver has a square shank so that a wrench can be used to help remove large screws Screwdrivers
Saws • Do not saw out the marked line because the board will be too small is it was measured and marked accurately. Saw on the waste side of the mark
Squares • Handle should be held firmly against the edge of the board
Don’t operate a machine until: • A) receiving proper instruction • B) you fully understand how to use it • C) you have permission • Always wear eye protection • Know and understand all the manufacturers’ safety rules
Use all guards exactly as they should be used • Make all adjustments with the power off • Power tools should be inspected and serviced at regular intervals by qualified repair people
Make sure everyone is clear BEFORE you turn on the power • Start and stop the machine yourself-STAY WITH THE MACHINE UNTIL IT STOPS !!! • Keep a safe distance between your hands and all moving parts
Operate the machine by yourself - unless you need a helper • Be sure all power tools are grounded with a 3-wire conductor cord when required • Before connecting to a power source, make sure the switch is “OFF”
