Table VII. Undergraduate Laboratory Safety Lecture Outline (based on OU LSSP coupled with OU Laboratory Safety Audit Form).

The organic chemistry laboratory is potentially one of the most dangerous of undergraduate laboratories. That is why you must have a set of safety guidelines. It is a very good idea to pay close attention to these rules, for one very good reason ... 

There are three cooling media commonly used in the laboratory crushed ice, solid carbon dioxide (Dry Ice , Drikold , Cardice ) and liquid nitrogen. You are unlikely to use liquid nitrogen in the undergraduate laboratory - if it is required you must consult your demonstrator about the special safety protocols required for its use. 

Safety note Because of its flammability and tendency to form explosive peroxides, the use of diethyl ether for extractions in many undergraduate laboratory has effectively been discontinued. Use dichloromethane or ethyl ethanoate instead. 

Energy consumption for chemical reactions (particularly for undergraduate laboratory reactions), since this is never measured in literature procedures, although guesses can be made based on reaction temperature and pressure conditions and operational procedures such as distillation it should be noted that reactions are never carried out above 1 atmosphere in the undergraduate laboratory due to safety concerns and the use of expensive and specialized equipment such as autoclaves... 

In research universities the inherent problems of transmitting good laboratory training to undergraduates can be compounded by the conflicting demands for resources and attention between research and undergraduate teaching. Commitment of the entire faculty to laboratory safety and the responsible disposal of chemicals is a crucial factor in the initiation of all students into the laboratory culture at every level. 

We conclude this introduction to safety with a key element to guide you in the undergraduate laboratory—the student safety ethic f In Section 1.3.2 we will introduce the the safety ethic, which expands the student safety ethic to include a full range of topics for practicing chemists and researchers.
