The primary purpose of a Pre-Startup Safety Review (PSSR) under OSHA PSM is to verify that:
Answer: Construction and equipment meet design specifications and safety systems are operational before introduction of highly hazardous chemicals
PSSR confirms that construction matches design, safety systems are functional, procedures are in place, and training is complete before highly hazardous chemicals are introduced to a new or modified process.
In safety instrumented systems, 'proof testing' is conducted primarily to:
Answer: Detect dangerous undetected failures that could prevent the SIS from performing its safety function on demand
Proof tests reveal dangerous undetected (dormant) failures in SIS components—failures that could prevent the system from actuating when a hazardous condition occurs.
A facility subject to EPA's RMP rule must review and update its hazard assessment at least every:
Answer: 5 years
EPA's RMP rule (40 CFR 68.36) requires that the hazard assessment be reviewed and updated at least every five years or whenever the process changes significantly.
Which of the following risk assessment matrices aligns hazard severity with mishap probability to determine risk levels as defined in MIL-STD-882E?
Answer: Risk Assessment Code (RAC) matrix
MIL-STD-882E uses a Risk Assessment Code (RAC) matrix that combines mishap probability categories with mishap severity categories to produce an overall risk level.
A chemical plant must report a catastrophic release of a listed substance under EPA's Emergency Planning and Community Right-to-Know Act (EPCRA) Section 304. The report must be submitted to:
Answer: State Emergency Response Commission and Local Emergency Planning Committee
EPCRA Section 304 requires immediate notification of releases of extremely hazardous substances to the State Emergency Response Commission (SERC) and the Local Emergency Planning Committee (LEPC).
The concept of 'defense in depth' applied to safety-critical systems means:
Answer: Layering multiple independent protection layers so that failure of one does not result in a catastrophic outcome
Defense in depth uses multiple independent protection layers (IPLs)—each capable of preventing the hazardous outcome alone—so that no single failure leads to catastrophe.
Under the OSHA Hazard Communication Standard (HazCom 2012 / 29 CFR 1910.1200), employers must maintain Safety Data Sheets and make them accessible to employees:
Answer: During all work shifts when chemicals are present
HazCom 2012 requires that SDS be readily accessible to employees during their work shifts whenever they may be exposed to hazardous chemicals in their work area.
