Safety in the Laboratory

Perform laboratory work only when your teacher is present. If you would like to try something “creative” ask your teacher if it is safe and do it under her supervision.

Never play or goof around with the laboratory instruments. All instruments and materials have a specific use or purpose.

Check chemical labels twice to make sure you have the correct substance. Some chemical formulas and names may differ by only a letter or number.

You may be asked to transfer some laboratory chemical from a common bottle or jar to your own test tube or beaker. Do not return any excess materials to its original container unless authorized by your teacher.

Avoid unnecessary movement and talk in the laboratory. FOOD and DRINKS are not allowed in the laboratory.

If you are instructed to smell something, do so by fanning some of the vapor toward your nose. Do not place your nose near the opening of the container. Your teacher will show you the correct technique.

Never look directly down into a test tube; view the contents from the side. Never point the open end of the test tube toward yourself or your neighbor.

Any laboratory accident, however small, should be reported immediately to your teacher.

Minor skin burns should be placed under cold, running water.

Return all materials to their designated locations.

Before leaving the laboratory, make sure that all faucets and electrical devices are shut off.

Put back the chairs under the table.

Always clean your work area (table top, floor area under your chair and table. )

If you are unclear or confused about the proper safety procedures, ask your teacher for clarification.

If in doubt, ASK.
