PSM 314: Prevention of Loss of Containment

COURSE DESCRIPTION                                                                                  DURATION: 3 Days

Loss of Containment of hazardous materials, toxic or flammable, is the primary cause of process safety incidents.  There are several causes which are the initiating events for Loss of Containment:

  • Operating outside of the safe operating envelope for process equipment
  • Poor management of process equipment integrity, and
  • Opening piping or equipment without proper clearing of material or adequate isolation of energy sources

This course shall discuss the types of events that could result in Loss of Containment and present administrative controls that can be utilized for preventing Loss of Containment in your plant.


  • Learn to prevent loss of containment incidents through previous incidents from across industry
  • Learn to prevent loss of containment through assessment of hazards, consequences, and risks
  • Learn to identify, maintain, verify and manage process-safety critical elements through case-study examples
  • Learn the tools to conduct near-miss and incident investigations

  • Managers, process safety coordinators, operators and others responsible to handle or manage hazardous materials, toxic or flammables in the plant

  • None
