LAB SAFETY
SAFTEY OF STUDENTS
The Biochemistry laboratory can be a place of discovery and learning.
It can be a place of danger if proper common-sense precautions aren't taken

GOOD LABORATORY CONDUCT
Follow all written and verbal instructions carefully.
If you do not understand a direction or part of a procedure, ASK YOUR TEACHER BEFORE PROCEEDING WITH THE ACTIVITY
![Page 9: Laboratory safety ppt](https://reader035.fdocuments.net/reader035/viewer/2022081417/554b18e0b4c90569098b4ed6/html5/thumbnails/9.jpg)
GOOD LABORATORY CONDUCT
Never work alone in the laboratory.
No student may work in the laboratory without the
presence of the teacher.

GOOD LABORATORY CONDUCT
Perform only those experiments authorized by
your teacher. Carefully follow all instructions, both
written and oral. Unauthoriz
ed experiment
s are not allowed.
![Page 11: Laboratory safety ppt](https://reader035.fdocuments.net/reader035/viewer/2022081417/554b18e0b4c90569098b4ed6/html5/thumbnails/11.jpg)
GOOD LABORATORY CONDUCT
Keep hands away from face, eyes, mouth, and body while using chemicals or lab equipment.
Wash your hands with soap and water after performing all experiments.
![Page 12: Laboratory safety ppt](https://reader035.fdocuments.net/reader035/viewer/2022081417/554b18e0b4c90569098b4ed6/html5/thumbnails/12.jpg)
GOOD LABORATORY CONDUCT
Be alert and proceed with caution at all times in the laboratory.
Notify the teacher immediately of any unsafe conditions you observe.

PROPER HANDLING OF CHEMICALS AND EQUIPMENT
Labels and equipment instructions must be read carefully before use.
Set up and use the equipment as directed by your teacher.
![Page 14: Laboratory safety ppt](https://reader035.fdocuments.net/reader035/viewer/2022081417/554b18e0b4c90569098b4ed6/html5/thumbnails/14.jpg)
PROPER HANDLING OF CHEMICALS AND EQUIPMENT
Many common reagents, for example, alcohols and acetone, are highly flammable.
Do not use them anywhere near open flames.
![Page 15: Laboratory safety ppt](https://reader035.fdocuments.net/reader035/viewer/2022081417/554b18e0b4c90569098b4ed6/html5/thumbnails/15.jpg)
PROPER HANDLING OF CHEMICALS AND EQUIPMENT
Always pour acids into water. If you pour water into acid, the heat of reaction will cause the water to explode into steam, sometimes violently, and the acid will splatter.
![Page 16: Laboratory safety ppt](https://reader035.fdocuments.net/reader035/viewer/2022081417/554b18e0b4c90569098b4ed6/html5/thumbnails/16.jpg)
PROPER HANDLING OF CHEMICALS AND EQUIPMENT
Never point a test tube or any vessel that you are heating at yourself or your neighbor--it may erupt like a geyser.
![Page 17: Laboratory safety ppt](https://reader035.fdocuments.net/reader035/viewer/2022081417/554b18e0b4c90569098b4ed6/html5/thumbnails/17.jpg)
PROPER HANDLING OF CHEMICALS AND EQUIPMENT
Beware of hot glass--it looks exactly like cold glass.

LABORATORY HYGIENE
Never eat, drink or smoke in a laboratory
Never apply cosmetics
Never touch your face, mouth or eyes

ELECTRICAL
EQUIPMENT
Always do a visual check on electrical equipment before use, looking for obvious wear or defects

GENERAL TIDINESS
Keep your workplace tidy
Clear up waste, deal with washing up and put things away as you finish with them
![Page 22: Laboratory safety ppt](https://reader035.fdocuments.net/reader035/viewer/2022081417/554b18e0b4c90569098b4ed6/html5/thumbnails/22.jpg)
LAB SAFTEY
Report any accident (spill, breakage, etc.) or injury (cut, burn, etc.) to the teacher immediately, no matter how trivial it seems.
DO NOT PANIC
![Page 23: Laboratory safety ppt](https://reader035.fdocuments.net/reader035/viewer/2022081417/554b18e0b4c90569098b4ed6/html5/thumbnails/23.jpg)
FIRST AID
For all chemical splashes, wash with plenty of water for 10
minutesControl bleeding with direct
pressure, avoiding any foreign bodies such as glass
![Page 24: Laboratory safety ppt](https://reader035.fdocuments.net/reader035/viewer/2022081417/554b18e0b4c90569098b4ed6/html5/thumbnails/24.jpg)
HANDLING GLASSWARE AND EQUIPMENT
Never handle broken glass with your bare hands. Use a brush and dustpan to clean up broken glass. Place broken glass in the designated glass disposal container.
If you do not understand how to use a piece of equipment,
ASK THE TEACHER FOR HELP!

WASTE DISPOSAL
Dispose of all chemical waste properly.
Never mix chemicals in sink drains.
Sinks are to be used only for water.
Check with your teacher for disposal of chemicals and solutions.
