characterized by their extremely low temperature and by their extremely high expansion rate when their physical state changes from liquid to gas. Other examples of common cryogens include liquid helium, hydrogen, argon, oxygen and methane. Due to these characteristics, work involving cryogenics presents certain health and safety hazards.
