5 days SEC/SAFENGRC-E
- Managers, engineers, technicians in charge of the design, the modification, the maintenance or the operation of industrial facilities.
- This course provides an overview of safety studies in a project and shines a light on how to define the main principles behind the design of systems of prevention, detection, mitigation and protection.
- To understand and apply the Codes and Standards used for Safety in Process design.
- Upon completion of the course, participants will be able to:
- use the consequence analysis at the very beginning of the project,
- apply the main codes and Standards for Safety Design (NFPA, API).
- Basic knowledge in Process, Instrumentation, Static and Dynamic Equipment.
Ways and means
- The main principles for safe design in simple installations are applied:
- interactive lecturing, by experienced lecturer(s),
- numerous exercises and applications (50% case studies or tutorial exercises),
- a number of Visual aids (Videos, Learning from Incidents (Texas City, Buncefield, Flixborough)).
RISK IDENTIFICATION 1 day
- Risk identification and acceptability with regards to people, environment and assets - Hazard and risk - Residual risk - Risk assessment matrix.
- Review of phenomena: gas dispersion, toxic release, thermal radiation, overpressure blast.
- Preliminary risk quantification: evaluation of risk consequences (grass root project or revamping) based on HAZID/HAZOP reviews.
INHERENT SAFETY DESIGN & LAYOUT OPTIMIZATION 0.5 day
- Layout optimization based on safety reviews: Safety distances - Fire zones - Deluge zones - Escape, egress and access systems.
- Minimizing the inventory: leak control, disposal (flare, diked area, …) and drainage systems.
TYPE OF SAFETY BARRIERS 0.25 day
- Safety barriers: technical, organizational, human; prevention, mitigation, protection, active/passive.
PREVENTION BARRIERS 1 day
- Pressure Equipment and Atmospheric Storage Tanks: selection of material of construction, corrosion, pressure resistance - Piping Classes.
- Overpressure and negative pressure protection: pressure safety valves, rupture discs: selection criteria, design, implementation, inspection.
- Safety Instrumented Systems (SIS) and Safety Integrity Level (SIL) - Typical architecture of Safety Instrumented Systems: hierarchy, interaction with process control system and Fire & Gas system.
DETECTION 0.5 day
- Fire & Gas system: technology of sensors, selection and location - Cause and Effect Matrix, Voting - Relationship with mitigation systems.
MITIGATION & PROTECTION SYSTEMS 1.25 days
- Minimizing ignition sources: ATEX, area classification, ventilation.
- Passive fire and blast protection: description of material, utilization, monitoring and inspection - Identification of surface/elements to be protected.
- Active firefighting systems: extinguishing agents (water, foam, dry chemicals, inert/inhibition gas).
- Fixed systems with water or foam: elements of the fire main system (main ring, fire water pumps, consumers, water tank, foam solution), application rate. Preliminary sizing of main ring, pumps and water/foam solution tank.
- Semi-fixed and mobile systems: description and operation of equipment.
HUMAN FACTORS 0.25 day
- Functioning of the human being - examples of systems embedding human behavior or human error: equipment accessibility, plant ergonomics, synoptic/graphic display design, alarm management, …
MANAGEMENT OF CHANGE 0.25 day
- Management of Change (MOC): technical, organizational and human expertise (reliability of documentation, suitability/application of the procedures, corporate specifications, …).
- Maintaining the efficiency of the barriers - Example of risk management tools: the bow tie.
