1. Demonstrating Safety & Appropriate Laboratory Procedures
8411_PPT

2. American Agriculture Uses: Modern chemicals Mechanical technology
Power
Produces:
Food
Clothing
Shelter
Recreation & relaxation
Other basic needs
For the WORLD!

3. Successful workers need
Knowledge & skills to:
construct;
repair; and
maintain
Residences
Buildings & fences
Machinery & equipment
Our environment

4. 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

5. Safety rules protect
Ourselves
Others
The environment

6. Safety rules Help people develop good work habits Prevent injuries
Increase productivity

7. Safety rules may vary based on:
Tools
Equipment
Chemicals used
Tasks performed

8. 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

9. 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

10. 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

11. ALWAYS pay attention to safety & warning signs
Safety dynamics enhances safety with:
Printed signs
Flashing lights
Color-coded information

12. 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

13. 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

14. 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

15. 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

16. 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

17. General Safety Reminders

18. 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

19. Main causes of hand tool injuries
Improper use of the tool
Using the wrong tool for the task
Using damaged tools
Using dull tools

20. 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

21. 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

22. Check electrical tools & extension cords &
For:
Damaged parts
Damaged plugs
Damaged insulation
Damaged grounding prongs
Before use

23. 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

24. 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

25. 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

26. 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

27. Special Hazards
Chemical hazards – paints, thinners, fuels, lubricants, cleaning solvents – can be:
Caustic
Flammable
Explosive
Toxic
But SAFE when used properly.

28. MSDS Sheets Post in a conspicuous location “Right to Know” center
Material Safety Data Sheets
Label information - Chemical composition
Instructions on:
Use
Handling
Storage
Disposal
Post in a conspicuous location
“Right to Know” center

29. 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

30. 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
