The following safety rules must be observed while performing any of the scheduled laboratory experiments in one of the Chemistry Laboratories. Students who are found in violation of the safety rules will be given a warning for the first offense, will be dismissed from the lab room for the second offense, and will be withdrawn from the class (lab as well as lecture) for the third offense. If a violation is observed at a particular lab table (such as spilled liquid - water or hydrochloric acid etc), and those working at that lab table deny responsibility, all students working at that table will be considered to be in violation of the safety rules. Please sign the accompanying sheet (Safety Certification) after you have read through the safety rules and regulations. Please ask your instructor if any of the items need clarification.
