AIChE CCPS Process Safety Professional Certification Sample Questions:

1. 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 system is operating normally under transient conditions
B) The pressure gauge is faulty and can be ignored
C) The rupture disc may have failed or leaked, compromising the relief system and creating overpressure risk
D) No hazard exists because the relief valve will always protect the system

2. A contractor has been hired to apply a proprietary coating in an unoccupied process area. The coating has hazardous properties. What documentation should the contractor provide to the site owner before starting work? (Select all that apply)

A) The contractor's procedure for handling and applying the coating
B) A plan on how the contractor will protect all site employees from exposure
C) The site owner is responsible for protecting the site employees, so no contractor documentation needs to be provided
D) No documentation is required since the contractor's technology is proprietary
E) A Safety Data Sheet (SDS) for the coating materials

3. Which of the following statements are true with respect to Compliance with Standards? (select all that apply)

A) It is valid for a company to develop its own internal standards
B) It is permissible to deviate from the requirements of the standard if compliance requires complex equipment modifications
C) Existing equipment must always comply with the most recent edition of the relevant standard
D) Standards should be updated to reflect new knowledge as it is acquired
E) Company internal standards are required to be updated before each process hazard analysis revalidation
F) Compliance with applicable codes and standards may not be sufficient to ensure safe plant operations

4. 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)

A) Work Orders
B) Positive Material Identification
C) Ultrasonic Thickness Measurements
D) Ultrasonic Leak Detection

5. Which of the following statements are true with respect to Compliance with Standards? (select all that apply)

D) Standards should be updated to reflect new knowledge as it is acquired
E) Company internal standards are required to be updated before each process hazard analysis revalidation
F) Compliance with applicable codes and standards may not be sufficient to ensure safe plant operations
