Read and follow direction carefully- note any special warnings. Lab partners should double-check each other. Double-check labels to make sure you are using the correct chemical. Wear goggles when indicated-always wear goggles when using, burners, acids, or bases. No exceptions to this rule.
Accidents do happen.
Report broken equipment immediately. Report any chemical spills immediately. Keep working area free of unnecessary materials. When heating a test tube, hold it tilted and point it away from other students. Never eat or drink anything during lab-some of the chemicals you will use are toxic.
