How Better Access to PHA Data Can Inform Your MOC Process

© Vanderbilt University Center for Teaching

In Bloom’s Taxonomy, “evaluation” is the fifth of six levels. Learners progress from remembering, to understanding, to applying, analyzing and then evaluating and finally creating.

One of the most important “evaluating” exercises in Process Safety Management (PSM) is the Process Hazard Analysis (PHA).

In a PHA, a group of people with expertise in the process (operators, engineers, etc.) gather to look at all the equipment and chemistry and technology involved.

They detail out each possible hazard, cause, consequence and safeguard. They review the risks, make recommendations, and put all of this information into a report.

Re-Evaluating in Process Safety

When you re-evaluate something, it’s typically done with an eye towards any changes or new information.

In PSM, we re-evaluate the hazards when we make a change through the management of change (MOC) process or when there has been an incident and we want to see what went wrong and if we missed something in the first evaluation of the hazard.

When you want to evaluate something again, it would seem natural to look at the original evaluation.

In significant incident investigations, the PHA report is often pulled up to determine if something was missed or a recommendation wasn’t completed.

But during the course of an MOC, it is very rare for the original PHA to be referenced.

Even if the project involves significant change and generates its own PHA, it is not always standard practice to reference the original unit PHA.

One reason for this is the great complexity of the information in a PHA and the challenges in finding a specific area.

In short, the PHA details aren’t always easily accessible.

And as I said, it’s not a standard practice.  Most MOC procedures I’m familiar with do not include a checkbox for looking at the original PHA.

In my many years as a process engineer, I was never advised to look at the PHA for the unit when doing a change. We simply did our own mini-PHA with the group of engineers and operators on hand.

PHA Data Can Be a Valuable Resource

But what about the great level of time and expertise that had already been invested in the most recent PHA? What if something we changed had been counted on for a safeguard? Maybe we caught it in our project group, but what if we didn’t?

There are many advantages to making PHA results and comments more structured and searchable.

One of those is the opportunity for engineers and operators to easily reference nodes and sections of a unit and review the hazards when a change is being proposed and reviewed.

It is one more way we can all have the best information on hand to make wise and safe decisions.


Our Managing Partner Patrick Nonhof presented a webinar on “Can PHA Be Big Data”. He discusses applicable, practical ways to make your PHA data more useful by addressing the barriers to its usability – lack of structure and lack of accessibility. The possibilities for data analysis and continual value-add on your PHA data is an untapped resource at many facilities. Let us help you realize that potential.

How to Protect Your Ship from Process Safety Hazards

In Star Trek, the ship is protected by a force field called a “shield”.  When under attack, the tactical officer will call out the status of the shield’s integrity, e.g. “shields at 70%, Captain.”  When shields are down to 10%, you know that a breach is imminent unless they retreat or find a way to defeat their attacker.

In a refinery or chemical plant, there is no one calling out the integrity of our protection systems and procedures every few minutes.

But OSHA has specified three specific process safety elements that are critical to Protect Against the Hazards (one of the Five PSM Mindets™) – Pre-Startup Safety Reviews, Mechanical Integrity, and Hot Work Permits.

Taking Action to Prevent Disaster

Once we’ve identified the hazards, it’s time to do something about it. We’ve seen where danger may strike, so we go to the possible sources. We anticipate what could go wrong and prepare for it.

  • We put procedures in place to create consistency and avoid mistakes. But are the procedures being followed? 
  • We add alarms and limits to alert us to known unsafe conditions. Will the appropriate alarms overwhelm the operator in the event of an emergency? 
  • We install systems such as relief valves and automatic shutdowns to react as quickly as physically possible if a dangerous limit is exceeded. Are the safety relief devices and shutdown systems being maintained according to industry standards?  What about the mechanical integrity of the pipes, pumps, or vessels? 

In a process hazard analysis (PHA), safeguards and layers of protection are identified and counted on.  And in our industry, there is a great deal of focus on mechanical integrity and maintaining safety instrumented systems.

The Shield Doesn’t Replace the Crew

In a successful process safety culture, the success or failure of the facility is the responsibility of everyone together – like the crew on Star Trek.

If you are going to help ensure the shields are at maximum strength, here are a few places to start:

  • First, know your enemy – become familiar with the hazards that have been identified and communicated to you.
  • Get to know what the protection layers are for the areas you work in.
  • When there are safe work practices and procedures in place, follow them closely. When you know the “why” behind the procedure, you can be on the lookout for any gaps or concerns.

The safety of a star ship isn’t just dependent on its shield. It depends upon each crew member doing their part and working as a team.

The safety of a facility isn’t just based on the safeguards put in place, but upon each person inside the gate doing their part.

You are more than helping maintain the “shield” – YOU are an integral part of the shield preventing catastrophe so that we may all “live long and prosper”.

How Telling Stories Creates Hazard Transparency

Most people enjoy a good mystery.

Writers like Agatha Christie are successful in bringing us into the intrigue by giving just enough clues for us to come up with our own hypothesis of “whodunit”, while withholding enough insight so that at the end, the master detective solves the case and uncovers the unexpected villain.

We are excited by the challenge of looking for clues, reading between the lines, searching for the truth.

For me as an engineer, that love of investigating a mystery contributes to the thrill of problem solving.

Dangers of “Whodunit” in Process Safety

When it comes to understanding process hazards in a facility, knowing the “whodunit” of process hazards goes beyond elementary entertainment.

OSHA designated the elements of Compliance Audits and Trade Secrets to make sure that everyone at the facility knows the whole story, not just a few clues.  Nothing is meant to be hidden from the employee, and no one wants a “surprise ending.”

These two elements also make up the fifth PSM Mindset™, Transparency.

Audits and sharing trade secrets allows everyone who needs it to see the real story of the process:  What are the risks, the protections, the gaps, and the strengths of the processes and procedures in place?

We Don’t Need Sherlocks – We Need Storytellers

As a mindset, it is also about each person on-site being willing to be transparent.

Are you willing to share your stories – what worked and, even more important, what hasn’t worked and why?

We all learn more from stories than from a list of facts.  We can put ourselves into the story, and our minds remember stories especially when the story invokes an emotion – This makes the memory more “sticky.”

If you have years of experience in the petrochemical industry, you have stories to share.  If you are new to the industry, there are lots of stories to hear, so be listening.

Sharing Experiences is Safer and Smarter

I have a vivid memory of a leak detected in the Hydrofluoric Acid Alkylation Unit flare accumulation drum.

Typically the unit would be shut down so the pipe could be replaced.  But that would send all the hazardous materials in the unit right through the leaking pipe.

I remember meetings with operators, engineers, maintenance, mechanical integrity inspectors and others to come up with a plan to safely address the issue.

We came up with a solution and put a temporary Management of Change form in place, formally getting everyone to sign and stack hands on the plan.

The plan worked, the pipe was bypassed and replaced, and I was left with a lesson on the importance of all eyes looking at the potential solution.

I remember the arguments, the concerns, the checking and double checking that was involved.  In the end, it was a success.

The hazard was addressed because everyone was transparent about their ideas and concerns.

What Should We Share?

If you see something that doesn’t align with a procedure or standard, that is a story that needs to be shared.

Is a level gauge not reading accurately? Don’t dismiss it, share that information.

Is a procedure or policy cumbersome and difficult to navigate? The complexity may be necessary but on the other hand, a simpler approach may work instead.

These are also stories that need to be told.  Each story may be part of a bigger picture.

Remember, there is no Sherlock Holmes or master detective on staff, so we all must work as a team to ensure the hidden risks are brought to light and the hazards are exposed.
