Demonstrating Safety & Appropriate Laboratory
Procedures
8411_PPT
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 tosafety & 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 propertools & 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
