      • Toxics, exposure limits, Safety Datasheet.
      • Low temperature burn.
      • Fluid behavior hazards:
      • Heat addition/removal consequences on closed circuit: pressurization, thermal expansion, vessel under vacuum, temperature drop due to vaporization, icing…
      • LPG storage pressure control: vapor condensation, cooling systems.
      • BLEVE: description of the phenomenon, different consequences, prevention and mitigation.
      • Examples of different hazardous situations and correct behavior: normal operating conditions (operator field check, purges, sampling), incidents (leak, fire), startup/shutdown operations, maintenance activities…

Learning Objectives

  • Upon completion of the course, the participants will be able to:
  • Describe the procedures for sampling liquefied gases related to the quality criteria and their compositions,
  • List, according to the regulations, the characteristics of the equipment used for storage, transfer, (de-)loading.,
  • List the operating rules, guaranteeing safety, to ensure good pumping conditions and to remedy malfunctions of the associated equipment,
  • Appreciate operating instructions for safe operation.

Ways & Means

  • The pedagogy is active and refers essentially to participants’ experience. The documentation delivered to the participants as training medium is also a reference document useful after the training session.
  • Case studies based on industrial situations.

Learning assessment

  • Final quiz.
