NEBOSH HSE PSM
Definition of Process Safety Management - correct answer A blend of engineering and management skills
focused on preventing catastrophic accidents and near misses, particularly structural collapse, explosions, fires and toxic releases associated with loss of containment of energy or dangerous substances such as chemicals and petroleum products.
Sources of Process Safety Management information: - correct answer Safety Data Sheets (SDS)
Process design criteria.
Process Flow Diagrams (PFD)
Standard Operating procedures (SOPs) setting safe limits, such as for temperatures, pressures, flows, compositions and levels as well as evaluation of the effects.
Inspection, audit and investigation reports.
Maintenance records.
Piping and Instrument Diagrams (P&Ids).
Process Control Systems, including software integrity.
Relief system designs.
Fire detection and protection plans.
Management Of Change - MOC - correct answer MOC is a management control approach to make sure that proposed changes are properly assessed and authorized.
Management Of Change - MOC - Requirements: - correct answer Hazard and Risk Analysis.
Process for all changes to be authorized.
Changes documented.
Consult and inform.
Training.
Workers Consultation - correct answer The two-way exchange of information between parties. In this case, between employer and worker. Definition of Competence - correct answer A combination of practical and thinking skills, experience and knowledge.
Elements of a Process Safety Management System - correct answer Element 1: Strong Leadership.
Element 2: Hazard Analysis.
Element 3: Management Of Change.
Element 4: Operation within design intent.
Element 5: Competence management. (Training).
Element 6: Control of Contractors.
Element 7: Asset Integrity.
Element 8: Emergency Response.
Element 9: Process Safety Incident Investigations.
Element 10: Performance Monitoting and Auditing.
Leading Indicators - correct answer Proactive measurements of conditions that monitor process safety before something goes wrong and to see if things are operating as intended.
Lagging Indicators - correct answer Reactive measures that took at failures, such as the number of injuries, the number of near misses and the number of spills that are reported, or excursions where plant is operated outside the intended operational envelope.
Five Steps for Risk Assessment - correct answer Step 1: Identify the hazards.
Step 2: Identify the people who might be harmed and how.
Step 3: Evaluate the risk and decide on precautions.
Step 4: Record the significant findings.
Step 5: Review and update as necessary.
Risk Assessment Techniques - correct answer 5 WHs: What, Where, When, How, Why.
