Question 1

Discuss the advantages and disadvantages of using competent third-party auditors for facility process safety audits.

A. Third-party auditors eliminate the need for internal audits

B. Third-party auditors provide independence but may lack site-specific knowledge and can be costly

C. Third-party auditors are always less effective than internal auditors

D. Third-party auditors only provide benefits with no disadvantages

Question 2

A process calls for the addition of a reactant over a certain period of time. The flow controller on the reactant' s feed line was out of calibration and reduced the flow rate of the reactant. The operator noticed the addition rate was too low and, contrary to the operating procedures, he opened a bypass valve around the flow control valve to increase the flow rate. As a result, the operator added the remaining reactant too quickly, and a runaway reaction occurred. Weaknesses in which of the following Risk Based Process Safety elements could have contributed to the cause of this incident? (Select all that apply)

A. Training and Performance Assurance

B. Asset Integrity and Reliability

C. Incident Investigation

D. Conduct of Operations

E. Workforce Involvement

Correct Answer: A,B,D

Question 3

Which of the following can be considered applicable inspection methods as part of an Inspection/Testing
/Preventive Maintenance program under the Asset Integrity and Reliability Element? (Select all that apply)

C. Work Orders

D. Ultrasonic Thickness Measurements

Question 5

For a vapor explosion in an unconfined and uncongested area, the amount of thermodynamic energy that ends up in the overpressure is approximately:

A. 2-5%

B. 10-15%

C. 50-75%

D. 0%

E. 100%

Question 6

A vessel has a rupture disc and pressure relief valve in series to protect against high pressure in the vessel.
There is a pressure gauge on the pipe between the rupture disc and the relief valve. The gauge normally reads zero. As part of regular maintenance inspections, these pressure gauges are supposed to be routinely checked.

Today, a pressure of nearly 50 psig (~3.5 barg) was observed by an operator. There is a significant hazard now. Identify the hazard and discuss which elements of Risk-Based Process Safety could have been involved in the development of this situation.

A. The pressure gauge is faulty and can be ignored

B. No hazard exists because the relief valve will always protect the system

C. The system is operating normally under transient conditions

D. The rupture disc may have failed or leaked, compromising the relief system and creating overpressure risk

Correct Answer: D

Question 7

Which of the following are best used to verify that an operator adequately understands training? (Select all that apply)

A. A written quiz or test that must be passed upon completion

B. A form signed by the operator indicating that the training was completed

C. An attendance sheet from the training course

D. Documentation from the trainer that the operator demonstrated understanding

Question 8

Which of the following Risk-Based Process Safety elements are expected to be most directly and frequently involved with the Emergency Management Element? (select all that apply)

A. Management of Change

B. Stakeholder Outreach

C. Training and Performance Assurance

D. Hazard Identification and Risk Analysis
