ASP Risk Assessment and Control 5

Question 1

A company wants to determine the likelihood that a fire suppression system will fail on demand. Which technique is MOST appropriate?

Accepted Answer

Fault Tree Analysis (FTA)

Answer

Fault Tree Analysis uses Boolean logic to calculate the probability of a top-level system failure by tracing contributing component failures.

Question 2

The concept of 'Defense in Depth' in risk control means:

Accepted Answer

Using multiple, independent layers of protection so no single failure causes an incident

Answer

Defense in Depth places multiple independent barriers between a hazard and harm so that a single barrier failure does not result in a loss.

Question 3

Under ANSI/ASSP Z10.0, the primary purpose of the 'Check' phase in Plan-Do-Check-Act (PDCA) is to:

Accepted Answer

Evaluate whether implemented controls achieved desired safety performance

Answer

The Check phase measures actual results against planned objectives to determine whether controls are working as intended.

Question 4

A 'Preliminary Hazard Analysis (PHA)' is MOST useful during which project phase?

Accepted Answer

Early concept or design stage

Answer

PHA is a high-level technique performed early in design when detailed information is limited but changes are least costly to make.

Question 5

Which of the following is an example of an 'inherently safer design' strategy?

Accepted Answer

Reducing the inventory of flammable solvent stored on-site

Answer

Minimization — reducing hazardous material quantities — is one of the four inherently safer design strategies (Minimize, Substitute, Moderate, Simplify).
