Question 1

How does future PSM address the growing issue of cybersecurity?

Accepted Answer

Future Process Safety Management technologies can address cybersecurity through the integration of advanced AI-powered threat detection and prevention systems, which allows constant surveillance for anomalies and suspicious activities in network activities by taking a proactive approach to cybersecurity.

Question 2

What is the role of digital twins in PSM?

Accepted Answer

The role of digital twins in PSM is important as they provide virtual replicas of physical systems that enable simulation and prediction of system behaviour under various scenarios. Digital twins can monitor, detect, and analyze potential hazards, leading to improved safety and decreased risk of accidents.

Question 3

What role will AI play in Process Safety Management in the future?

Accepted Answer

In the future of PSM, AI can use primarily to predict potential risks, facilitate real-time decision-making, and improve maintenance procedures. It allows for the analysis of large data sets to spot patterns and predict equipment failures or disruptions in operations, thus improving efficiency and safety. Moreover, AI can aid in making real-time decisions by providing actionable insights, greatly reducing the risk of human error.

Question 4

What is the future trend in process safety?

Accepted Answer

The future of process safety is moving towards increased use of digital technologies, such as AI, IoT, advanced analytics, robotics and digital twins for real-time risk assessment and predictive maintenance.

Question 5

What is HAZOP in process safety?

Accepted Answer

HAZOP stands for Hazard and Operability Study, which is a systematic and structured method of identifying and evaluating hazards in industrial processes.

Question 6

Why is HAZOP required?

Accepted Answer

HAZOP can help to identify and solve the common operability issues such as maintenance, startup, isolations, etc. as it provides a rigorous and systematic check of the design in terms of safety, operability, and conformity to the standards.

Question 7

How is HAZOP carried out?

Accepted Answer

HAZOP is a brainstorming session – carried out in workshop format – with objectives to identify any design or operability issue within the facility that might lead to safety or operation problems. HAZOP session should consist of a team with a multidisciplinary background, guided
by a Facilitator. To help the brainstorming done systematically list of guidewords is used during the workshop and a Scribe will minutes the points result from the brainstorming.

Question 8

What is the main purpose of the HAZOP study?

Accepted Answer

HAZOP study is done to identify design or operational faults etc. leading to safety or operability problems.

Question 9

How do you prepare for HAZOP?

Accepted Answer

Typically, the scope of the HAZOP is discussed in the document known as the Terms of Reference. This document will be passed to the attendees, along with marked-up P&IDs which indicate how the process is split up into nodes.

Question 10

When should HAZOP be done?

Accepted Answer

HAZOP can be done at any stage of a project as long as sufficient information is available such as piping and instrumentation diagram (P&ID). HAZOP can be revisited when there’s a design change impacting the P&IDs.

Question 11

What are the types of HAZOP?

Accepted Answer

(a) HAZOP for Continuous Operations
(b) HAZOP for Batch Operations
(c) Procedural HAZOP (i.e., Start-Up)
(d) Control HAZOP (CHAZOP)
(e) Electrical HAZOP (EHAZOP)/ Electrical Systems Safe Operability Review (SAFOP)

Question 12

What is difference between PHA and HAZOP?

Accepted Answer

Process Hazards Analysis (PHA) is a study of process hazards that include methods like HAZOP, What-If and Checklist. Hazard and Operability Analysis (HAZOP) is a structured and systematic technique for identifying possible hazards in a work process.

Question 13

How do you identify nodes in Hazop?

Accepted Answer

Identified nodes through:
1) Design Intent
2) Significant change of process conditions
3) Equipment/System
