ABC of Safety in the Biological Sciences
(Carbon Dioxide, Liquid Nitrogen, Liquid Oxygen)
Safe handling of cryogenic liquids requires a knowledge of their properties and a common sense approach to precautions and procedures. Before using any cryogenic fluid ensure the laboratory has the necessary safety facilities (see below) should any spill occur, and that all staff are adequately trained in the hazards, handling and use of that fluid. Hazard data sheets must be obtained on all cryogenic liquids used.
The following are some general points related to the safe handling of cryogenic fluids.
This list is by no means comprehensive always obtain specific information on the particular cryogenic fluid intended for use.
