NEBOSH HSE PSM questions with verified
answers
Asset Integrity Ans✓✓✓-The ability of the equipment or asset to operate as
intended effectively and efficiently over its entire lifespan while ensuring the
health and safety of those exposed to it, including the environment.
Asset Life Cycle Ans✓✓✓-Phase 1 - Design.
Phase 2 - Procurement, construction, installation and testing.
Phase 3 - Commissioning.
Phase 4 - Operations.
Phase 5 - Modifications.
Phase 6 - Decommissioning.
Brittle Fracture Ans✓✓✓-Occur suddenly when the material is put under
excesive stress and has no, or limited, elasticity.
Catalysed and Uncatalysed Reaction Ans✓✓✓-A Catalyst is a medium put into a
reaction vessel that changes the pathway (mechanism)of a reaction
so the particles are forced into closer proximity. This increase the speed of a
reaction by lowering the
activation energy. Catalysts are not destroyed or changed during a reaction and
are generally reusable,
although they may suffer from poisoning by contamination with undesaired trace
substances in the reaction.
Conditions for dust to become explosive Ans✓✓✓-Particle size.
, Dispersal.
Explosive concentrations. Dust has indicative values like LEL 25-50 g per cubic
meter and UEL ten times the LEL.
Ignition energy.
Heat and humidity.
Content of an Emergency Plan Ans✓✓✓-Systems for alerting and warning
workers.
Responsibilities in the event of an emergency.
Expertise of teams responding to an incident.
Evacuation and shelter arrangements.
Emergency shut down of plant and services.
Management of vulnerable people and communities.
Definition of systems for accounting of workers. (Roll Call).
Contractor Management Ans✓✓✓-Contractor selection.
Periodic review of contractor safety performance.
Contractor induction and obligations to provide information on site risks.
Contractor ownership and site supervision/representation.
Auditing contractor performance.
Contractor handover to client.
