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
