SAFETY RULES

CHEMISTRY is an experimental science. In the laboratory, you will get your hands dirty. The experiments chosen for this class are designed to be safe. However, carelessness or foolish behavior can change a safe experiment to a very dangerous one. Chemicals should be treated with respect. READ the lab experiment before coming to class. KNOW which chemicals will be used. Let's make our chemistry lab the fun place it should be.
GENERAL

0. Be on time! If you show up late, you will miss the prelab quiz and may not have enough time to complete your experimental work.
1. Do not perform any unauthorized experiments. If you wish to try something different than what is in the Manual, ask the Instructor.
2. Never work in the lab unless the Instructor is present.
3. Eating and drinking in the lab is not permitted.

4. Open-toed shoes and sandals are not permitted.
5. Keep your work area clean. Know where the bottles are for acid spills.

6. You must go to the Infirmary for treatment of any cuts or burns. The Instructor will arrange for transportation if necessary. EYE PROTECTION 7. Safety goggles must be worn when chemicals are being mixed or heated by anyone in the lab. Eyeglasses do not provide for splash protection.

8. If you do get a chemical in your eyes, go immediately to the fountain and wash them with flowing water for several minutes.

FIRE PROTECTION
9. Know where the fire extinguishers and safety shower are located.
10. If clothes should catch fire, go immediately to the safety shower and pull the chain or use the fire blanket..

11. Persons with long hair or beards must secure them away from the burner flame. Scarves or loose clothing should also not be worn.
12. Never leave lighted bunsen burners unattended. When finished using them, be sure the gas is turned off.

CHEMICAL HANDLING 13. Reagents (chemicals) to be used in the day's experiment will be on the Reagent table. If something is missing, see the Instructor. DO NOT take any chemicals from the storage cabinets.

14. Never take any chemical substance out of the laboratory. This is grounds for expulsion from the course and possible expulsion from the University.
15. Always use the smallest amount of reagent possible. Take out of a bottle only what you need. NEVER return unused portions of a reagent to their original bottle.

16. When it is necessary to smell a gas or vapor, first waft a tiny amount of vapor toward your nose. Never fully inhale an unknown vapor.
17. Never add water to a concentrated acid or base. Always add the reagent to water. Remember "A to W".
APPARATUS HANDLING
18. When using glassware, clamp it in place.
19. Before using any glassware, check it for cracks. Replace any defective glassware before using it in an experiment.
20. Do not use heat "soft" glass test tubes. Use tubes made of borosilicate glass (Pyrex, Tekk, Kimax).
=======================================================================
After all these warnings, you may be afraid to step into the lab. Fear is the worst attitude. Be cautious... be careful... be thoughtful... but do not be afraid. You are here to learn and learning safety is part of the course. Every precaution will be taken by the Instructor and the University for your protection. Remember that the ultimate responsibility for safety in the lab rests on your own shoulders.

Laboratory Equipment Shapes

The following laboratory equipment shapes are included in professional version Edraw Maxscientific illustration software. Every chemical lab symbol are smart. The designers can easily create the chemical lab diagrams with the shapes.

Basic Chemical Lab Equipment Shapes

Dropper is ideal for simplistic liquid handling for pharmaceutical, laboratory chemical, cosmetic, aroma therapy and herbal uses.

Gas Jar is a container used for collecting gas from experiments. It looks like a tube with a broad base and a broad opening.

Beaker is usually used as containers in which to mix various liquids or as measuring devices.

Flasks are all containers or vessels, usually designed to carry a liquid and often made of glass. The software includes flat bottomed flask, circle bottomed flask, conical flask, pear-shaped flask and suckion flask.

Test Tube is usually used to hold the substance in place and that u can observe reactions taking place.

Measuring Cylinder is used to measure the volume solutions, liquids or water.

Acid Burette and Alkaline Buretteare simultaneously occupied by the presence of a liquid measuring and transferring this derailment.

Condenser is used to cool hot vapors or liquids. A condenser usually consists of a large glass tube containing a smaller glass tube running its entire length, within which the hot fluids pass.

Kipp's Apparatus is a laboratory apparatus for producing a gas by the action of a liquid on a solid without heating.

Separator Funnel is used to separate the components of a mixture between two immiscible solvent phases of different densities.

A funnel is used to transfer liquid or fine-grained substances into containers with a small opening without a spillage.

Desiccator is a short glass jar fitted with an air-tight cover, and containing some desiccating agent, as sulphuric acid or calcium chloride, above which is suspended the material to be dried, or preserved from moisture.

Crucible is used to hold small amounts of chemicals during heating at high temperatures.

Alcohol Burner is used to provide a hot, consistent flame for lab experiments or for heating something for a science project.
