Always wear safety glasses!

Never work alone. The instructor or TA should always be present.

Know the physical, chemical and physiological properties (as far as possible) of the reactants, solvents and products for each preparation and use appropriate precautions. You should treat every chemical as if contact is hazardous to your health.

Know where the fire extinguishers, eye washes, and emergency showers are located and do not hesitate to use them.

Know the proper disposal methods for chemicals you will be using.

When a reaction is left alone for extended periods of time (or any time you are not present) leave a note next to it with important facts for others working in the vicinity.

Check the entire lab carefully before using a flame to seal a glass ampule and make it known to others working in the lab when you are using flammable solvents, evoling H₂, etc.

Make sure you determine and follow any special safety prevautions required for your experiments (e.g., precautions for photochemical reaction, high pressure reactions, etc.)
