3 days HSE/AREACLASSGB
Level
Foundation
Audience
  • Engineers, technicians and staff, not familiar with the concepts of safety engineering, involved in operating oil and gas field processing facilities or in designing oil and gas projects architecture
Purpose
  • To explain the flammability hazards associated to production of oil & gas and to describe how to define a hazardous area and the applicable procedures to operate
Learning Objectives
  • To explain the flammability hazards associated to production facilities
  • To describe a scenario of loss of containment and to identify the most common hydrocarbon release points
