This course covers how to safely work with cryogens such as liquid nitrogen. The course is divided into two sections. In the first section, we discuss the general hazards posed by cryogens, first aid for cryogenic burns, oxygen depletion hazards and how to transport cryogens. Everyone who works with cryogens should complete part 1. In the second section, we discuss how cryogens are stored, risks of pressure explosions and the hazards of non-inert cryogens. Part 2 should be completed by researchers who are responsible for the maintenance of cryogenic Dewars and cylinders and those who work with non-inert cryogens such as liquid oxygen.
Everyone who uses cryogenic liquids
