tasks
![Page 5: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/5.jpg)
Safety rules protect
• Ourselves
• Others
• The environment
![Page 6: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/6.jpg)
Safety rules
• Help people develop good work habits
• Prevent injuries
• Increase productivity
![Page 7: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/7.jpg)
Safety rules may vary based on:
• Tools
• Equipment
• Chemicals used
• Tasks performed
![Page 8: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/8.jpg)
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
![Page 9: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/9.jpg)
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
![Page 10: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/10.jpg)
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
![Page 11: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/11.jpg)
ALWAYS pay attention tosafety & warning signs
Safety dynamics enhances safety with:
• Printed signs
• Flashing lights
• Color-coded information
![Page 12: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/12.jpg)
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
![Page 13: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/13.jpg)
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
![Page 14: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/14.jpg)
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
![Page 15: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/15.jpg)
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
![Page 16: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/16.jpg)
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
![Page 17: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/17.jpg)
General Safety Reminders
![Page 18: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/18.jpg)
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
![Page 19: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/19.jpg)
Main causes of hand tool injuries
• Improper use of the tool
• Using the wrong tool for the task
• Using damaged tools
• Using dull tools
![Page 20: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/20.jpg)
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
![Page 21: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/21.jpg)
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
![Page 22: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/22.jpg)

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
![Page 26: Demonstrating Safety & Appropriate Laboratory Procedures 8411_PPT.](https://reader034.fdocuments.in/reader034/viewer/2022051820/56649da75503460f94a934a0/html5/thumbnails/26.jpg)
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
