3. Lab Safety Rules
A few reminders when working in the lab and classroom:
No food or drink in the lab unless I specifically tell you otherwise.
Always read, re-read, re-re-read instructions, and be sure to ask questions before you get too far into an experiment.
Please be mindful of the fact that there will often be close to 30 people in the lab with you and that your safety and theirs is ALWAYS your first concern.
Familiarize yourself with lab equipment, safety symbols, and the location of first aid materials before beginning an experiment.
