Resource Review: Cryogen Safety (ESH 0170)

This online training purpose was to communicate the main hazards and controls associated with work involving cryogens so that workers have a foundation for working safely. It is intended as a support to on-the-job training so that workers have a foundation in understanding the potential risks associated with cryogens and the measures the Lawrence Berkeley National Laboratory uses to mitigate and prevent these. The training incorporates lessons learned as a way for participants to identify safety issues, some of the factors that led to their occurrence and how they can be prevented. At the end of this course, it is expected that the trainee will be able to:
  • Identify three primary hazards associated with cryogens and methods used to control these
  • Identify PPE requirements for working with cryogens
  • Given a series of lessons learned, be able to identify causes of injuries and factors that could have prevented them
  • Identify first aid response measures associated with working cryo splash and cryo burns
  • Identify requirements for transporting and shipping cryogens
  • Identify how to safely fill transfer Dewar from a large 160L Dewar
  • Locate information for determining the rules related to transporting cryogens
