Recognise consequences on processes using cryogenic materials

Control measure knowledge

Cryogenic materials are frequently used to provide an inert atmosphere or cooling in an industrial process, predominately to ensure that flammable materials do not have access to oxygen and thus preventing combustion. Cooling is typically used to control the rate at which reactions occur. Controlling the reaction rate limits the potential for thermal runaway reactions and of an explosion or fire in the reaction process. Release of the cryogenic material therefore not only creates hazards relating to the material itself, but also a loss of control of the process in which the cryogenic material was being used.

Strategic actions

Fire and rescue services should:
  • Ensure that personnel are aware of sites using cryogenic material in an industrial process

  • Develop site-specific response plans for sites using cryogenic materials in industrial processes that are assessed as high risk

Tactical actions

Incident commanders should:
  • Liaise with on-site personnel to ensure all processes that were supported by the cryogenic material are stopped, where it is safe to do so

  • Evaluate the need for evacuation

  • Determine with on-site personnel whether emergency arrangements are available for maintaining control of the process
