Question
search the internet for ( 5 ) safety videos that are specific to general chemistry lab safety (example “Lab Techniques & Safety: Crash Course Chemistry #21 via http://www.sciencebuddies.org/science-fair-projects/project_ideas/Chem_Safety.shtml ).
Take notes while you watch each video to completion. Prepare a report with a paragraph for each video including several things that you learned, found interesting, and observations like correct lab safety practices or improper attire. If you find flaws, provide critiques. It may be helpful to read through some of the feedback of other viewers (like in the comments section on Youtube). Then rate the videos from best to worst and write a summary
Explanation / Answer
Laboratory Safety are the principle which govern laboratory practitioner in order to be safe when handling his procedure in a laboratory
1.Wear safety glasses/goggles whenever you are in the lab. Aprons are required for some experiments. You may wear aprons at your discretion for any experiment to avoid staining or ruining your clothing.
2.Do not taste, touch, or smell any reagents unless directed to do so by your teacher. When smelling chemicals or gases, use a wafting motion to direct the odor toward your nose.
3. Keep flammable and combustible materials away from open flames. Some examples of flammable materials include alcohol, carbon disulfide, and acetone.
4. When heating a substance in a test tube, be careful not to point the mouth of the test tube at another person or yourself.
5. Use caution and the proper equipment to handle hot objects. Cool glass looks just the same as hot glass.
6. Handle chemicals carefully. Check the label of all bottles before removing the contents. Take only as much as your need. Do not return unused chemicals to reagent bottles. Report all spills or incorrect procedures to the teacher.
7. Handle toxic or combustible gases or chemicals only under the direction of the teacher. Use the fume hood when using these materials or when directed to do so.
8. Know the correct procedure for mixing acid solutions. ALWAYS add the acid slowly to the water. Never add water to a large amount of acid.
9. Never handle broken glass with your bare hands. Use a brush and dustpan to clean up broken glass. Dispose of the glass as directed by your teacher. Record and report all breakage or loss of apparatus to your teacher.
10. Keep insoluble waste material out of the sink. Dispose of waste material as instructed by your teacher.
11. Work areas should be clean and tidy at all times.
Chemical safety
Electrical safety
When you are adjusting any high voltage equipment or a laser which is powered with a high voltage supply, USE ONLY ONE HAND. Your other hand is best placed in a pocket or behind your back. This procedure eliminates the possibility of an accident where high voltage current flows up one arm, through your chest, and down the other arm
