Working with extreme temperatures, both high and low, is an integral part of many laboratory operations. For many, mentioning a laboratory instantly evokes the mental picture of a Bunsen burner. Bunsen burners and hot plates are used extensively in small and large operations in research laboratories and industries, thus making it necessary for all users to be aware of their safe handling procedures. Hot plates and Bunsen burners are high temperature heat sources, while low temperatures are obtained using dry ice and cryogenic liquids, such as liquid nitrogen. Both dry ice and liquid nitrogen can pose significant hazards to the user if not handled carefully.

While the use of Bunsen burners, hot plates, dry ice, and liquid nitrogen is commonplace in the laboratory environment, all of them can cause potential hazards if not handled carefully. It is thus the duty of every user to follow all the safety guidelines to eliminate hazards to themselves and their co-workers.
