CSP Hazard Identification and Risk Assessment 3

Question 1

A Preliminary Hazard Analysis (PHA) is typically performed at which stage of a project or system's life cycle?

Accepted Answer

In the early conceptual or design phase, before detailed design is completed

Answer

PHA is conducted early in the conceptual or design phase to identify potential hazards when changes are least costly to make, before detailed engineering is finalized.

Question 2

What distinguishes quantitative risk assessment (QRA) from qualitative risk assessment?

Accepted Answer

QRA uses numerical probability values and consequence estimates to calculate risk; qualitative uses descriptive categories like high/medium/low

Answer

Quantitative risk assessment assigns numerical probabilities and consequence magnitudes to calculate specific risk values, while qualitative assessment uses descriptive scales without precise numerical calculations.

Question 3

In a risk assessment, 'inherent risk' (also called 'gross risk') refers to:

Accepted Answer

The risk level before any controls or safeguards are applied to the hazard

Answer

Inherent (gross) risk is the level of risk present before any controls are applied — it represents the raw hazard potential without mitigation measures in place.

Question 4

When conducting a hazard identification walk-through, which approach is most consistent with best practices for the CSP exam?

Accepted Answer

Use a systematic, pre-planned checklist covering all work areas and tasks, involving workers who perform the tasks

Answer

Best-practice hazard identification walk-throughs use systematic checklists covering all areas and actively involve workers, who have valuable firsthand knowledge of hazards in their tasks.

Question 5

Which of the following best describes an 'acceptable risk' level in occupational safety?

Accepted Answer

A risk level that society or an organization deems tolerable given the benefits and costs of further risk reduction

Answer

Acceptable risk is not zero risk but a level deemed tolerable by stakeholders (workers, management, regulators, society) after weighing the benefits of an activity against the costs and feasibility of further risk reduction.
