American Agriculture
Uses:
• Modern chemicals
• Mechanical
technology
• Power
Produces:
• Food
• Clothing
• Shelter
• Recreation &
relaxation
• Other basic needs
For the WORLD!
Successful workers need
Knowledge & skills to:
– construct;
– repair; and
– maintain
•
•
•
•
Residences
Buildings & fences
Machinery & equipment
Our environment
Agricultural mechanics
• Part of a well-rounded education to:
– Reduce labor & material costs
– Select & properly use tools & equipment
– Save time
– Solve mechanical problems, and
– Be neat accurate & safe while completing
tasks
Safety rules protect
• Ourselves
• Others
• The environment
Safety rules
• Help people develop good work habits
• Prevent injuries
• Increase productivity
Safety rules may vary based
on:
•
•
•
•
Tools
Equipment
Chemicals used
Tasks performed
ALWAYS wear appropriate
PPE
• Eye protection - ANSI Z87.1 standard
• Includes: welding helmets, goggles,
face shields
• Includes: aprons, work boots, hard hats,
gloves
• Includes: hearing protectors, safety
harnesses, respirators
ALWAYS keep the facility
clean & tools in their proper
place
• Keep tools in proper place when not in
use
• Keep benches & floors clean;
a clean facility is a safe facility
• Store fire hazards (oily rags, sawdust,
etc.) in proper containers
ALWAYS practice safety
procedures
• Scuffling or horseplay endangers everyone
• Unsafe behaviors:
running, playing w/tools, disrupting others,
unnecessary loud noises, disobeying safety
rules
• Ignoring lockout tags endangers someone in
another part of the facility
• One reckless / inconsiderate worker makes
the entire facility unsafe
ALWAYS pay attention to
safety & warning signs
Safety dynamics enhances safety with:
• Printed signs
• Flashing lights
• Color-coded information
Basic safety color-coding
• RED = danger; fire extinguishers, Stop
buttons, hazards, flammable liquid containers
• ORANGE = warning; moving parts, crush
hazards, pinch points
• YELLOW = caution; operating controls,
aisles, handrails, fall hazards
• YELLOW & BLACK stripes = safe zones or
lanes; caution signs & traffic lanes
More safety colors
• Safety Gray / Vista Green = safety; safe body
parts of equipment, tool storage containers
• Ivory = improved visibility; edges of benches
& equipment, insides of cabinets
• Safety green = medical attention-getter;
safety equipment & first aid kit locations
• Safety blue = information; ‘out-of-order’ or ‘do
not operate’ signage
Even more safety colors
• Safety purple & radiation hazard logo=
radiation hazards; x-ray equipment
• Safety Orange-Red & biohazard logo =
biological hazards; bodily fluids,
infectious waste
ALWAYS use proper
tools & equipment for the task
• Each tool is designed for a particular
use
• Improper use results in accidents and /
or broken tools
• Check condition of tools & equipment
before using
• Do not use broken or damaged tools &
equipment
ALWAYS think before you act
• Do not endanger yourself or anyone
else while you are working
• Accidents can be avoided when people:
– Think about what they are doing, or
– Ask for help
General Safety Reminders
Moving heavy objects by hand
• Lift with your legs – avoid back &
stomach injuries
• Feet apart, knees bent, back straight
• Do not shift hands or body while lifting
• Lower the load the same way it was
lifted
• If the load is too heavy, ask for help
Main causes of hand tool
injuries
•
•
•
•
Improper use of the tool
Using the wrong tool for the task
Using damaged tools
Using dull tools
Hand tool precautions
• Never leave tools laying around if not in
use
• Do not carry tools in your pocket
• Secure small work; use a vise
• If possible, make cuts/ point tools away
from body
Basic rules - electrical
equipment
• Locate main disconnect & branch circuit
switches before using equipment
• Use branch circuits equipped with equipment
safety ground conductors & grounded
receptacles
• Use branch circuits equipped with GFCI's
with portable electric equipment outdoors or
in damp areas
• Check GFCI operation periodically
Check electrical tools &
extension cords &
For:
• Damaged parts
• Damaged plugs
• Damaged insulation
• Damaged grounding
prongs
Before use
More basic electrical rules:
• Use extension cords properly sized for the
load
• Don NOT place extension cords
– Across aisles
– Under heavy objects
– Where they will drag across sharp edges
• NEVER operate power tools in damp or wet
areas, unless specifically designed for such
use
• Wear rubber-soled shoes when using
electrical equipment
Texas Eye Safety Act
• Students MUST wear appropriate eye
protection devices when working in
educational laboratories
• Use only eye protection that meets ANSI
Z87.1 Standard – OSHA standard
• Glasses MUST have side shields
• Use chemical / splash goggles when needed
• “Three Strikes & Out” industry policies
Hearing Protection
OSHA requires hearing protection when
working around noises averaging:
– 90 dB in an 8-hour workday,
– 95 dB for 4 hours,
– 100 dB for 2 hours, or
– When peak noise level reaches 115 dB for
15 minutes
Noise Reduction
• Most industrial quality earplugs &
earmuffs rated at 20 – 30 dB
• Properly-worn ear plugs can reduce 100
dB noise entering the ear canal to the
75 dB range
• Do NOT reduce hearing to the point
where you cannot safely communicate
with other workers
Special Hazards
• Chemical hazards – paints, thinners, fuels,
lubricants, cleaning solvents – can be:
– Caustic
– Flammable
– Explosive
– Toxic
But SAFE when used properly.
MSDS Sheets
• Material Safety Data Sheets
• Label information - Chemical composition
• Instructions on:
–
–
–
–
Use
Handling
Storage
Disposal
• Post in a conspicuous location
• “Right to Know” center
Chemical Safety Guidelines
• NEVER handle hazardous chemicals without
proper training
• NEVER handle hazardous chemicals without
proper PPE
• ALWAYS store chemicals in properly marked
& labeled containers
• ALWAYS clean up solvent / chemical spills
immediately, using recommended method
Compressed air &
Volatile fluids
• NEVER point an air nozzle directly at yourself
or anyone else
• NEVER kink a hose to shut off flow
• NEVER use compressed air to remove fine
metal shavings
• ALWAYS use lowest possible air pressure
• ALWAYS use only pressure-regulated,
OSHA-approved safety air nozzles
