What is risk?
Risk is the possibility of losing something of value. Risk can also be defined as the intentional interaction with uncertainty. Uncertainty is a potential, unpredictable, and uncontrollable outcome; risk is a consequence of action taken despite uncertainty.
Risk perception is the subjective judgment people make about the severity and probability of a risk and may vary person to person, and company to company. Any human endeavor carries some risk, but some are much riskier than others.
So where does IndustryDocs What-If Process Hazards Analysis (PHA) play a role in risk minimization at your facility?
What-If PHA provides a systematic approach for evaluating risk in your workplace with an easy-to-use spreadsheet approach that is populated by those employees that understand the operation and maintenance, known hazards of the commodities, and have knowledge of previous incidents.
You begin by gathering ALL information related to previous incidents. What has happened? Why did it happen? Were there injuries? What was done to prevent a recurrence? Have there been “like” incidents since?
And don’t forget near-misses…were there “almost tragedies” that by a stroke of luck or the quick actions by employees that averted major incidents? What about incidents where there were no injurues; however, were there thousands of dollars of waste or off-specification product?
One of the great benefits of a process hazards analysis is that the PHA team can dig into countless areas where the bottom line of an organization can be adversely impacted.
Once previous incidents have been identified and reviewed, a true starting point to study hazards at your facility can begin.
You may not realize it or truly understand the organization of your facility but nearly every facility has some straightforward levels of organization. This can be areas and resources such as the following:
The above simply touches on how facilities have been organized; some facilities are organized down to micro levels of minutiae and this type organization can favorably influence risk evaluation by allowing the PHA team to dig deep into the details. However, to fully support a comprehensive full review of hazards in a facility such detail is not required.
Quick Start with What-if PHA
The most efficient way to begin the PHA process is to identify your physical areas of your facility then identify the equipment within each area. Next, place these data into a spreadsheet and use the Import Equipment feature within What-if PHA (see Lookup Tables; Import Equipment).
This list becomes “The Where and What you will be evaluating” for the entire PHA study. An inclusive list of AREAS and EQUIPMENT within the process is a must for any PHA! The software does a great job of allowing the user to populate a spreadsheet and performing an import.
Previous Incidents -- Once all areas and equipment have been organized, review this list against your account of previous incidents. From these previous incidents, devise a set of questions that cover each equipment item complete with a question and a scenario. As an example, based on a previous incident that resulted in an injury you would want to cover the following:
The above is an example and there are many more the team will most likely bring to the forefront. The object is to assure the actions accepted by management have all been implemented for all previous incidents since the most recent PHA.
What is the Master What-If Question Table?
The software provides a sampling of a set of questions that the user can either use or expand upon for their PHA study within the Master Question Table worksheet. For each question the user can apply a specific equipment type. Once the equipment reference has been made the user can use this as a library for present and future PHAs under the Select Questions worksheet. The Select Question worksheet allows the user to filter by a question category and equipment type; a feature that will add significantly to the management of a question set.
The What-If Matrix
Although the software provides an industry compatible risk ranking matrix, the user can customize this within the Risk Matrix worksheet. This section of the software is where the formula,
Risk = Likelihood x Consequence
is specified for the system to calculate risk for each What-If question. As an example, if we were to look at the risk of an airplane crash into the main process area of a facility we could say:
What is the likelihood of an airplane crash into our facility? The first question one might ask is, “How close is the facility to an approach path for an airport? Is this a commercial airport or a small airplane landing area? Has a plane crashed into the facility before? If the answers to the above are, no airport nearby, has never occurred, and the likelihood is deemed to be “Improbable” the software would assign the event a Value 1.
Next, we would look at consequence and completely erase the word likelihood out of the equation because consequence has NOTHING to do with the likelihood. Regardless, a crash into a facility would most likely be catastrophic. According to the consequence table the software would assign “Catastrophic” A.
The calculation for the over all risk would be 1A (likelihood X consequence). In summary the assessment value within the table provided classifies this as “Acceptable after review of the operation. Continued tracking and recorded action plans are required.”
This may require management to incorporate the crash of an airplane into the facility into their disaster recovery plan, which in most instances is a standard approach for most operators.
Load the software and begin your PHA?
Yes, a user can use the What-if Sample and begin by copying the workbook to a new name, erasing the contents, and begin. In fact, this may be the best way to get acclimated to the PHA process. You will soon see that all cells are unprotected; however, ensure the columns E, F, and G are preserved as this is the auto-population for the risk ranking. Otherwise, the user is free to remove and populate the worksheet as required.
Ad-hoc PHAs for review of new equipment, new process, new chemical, etc.?
The software is intended for regulation mandated hazards analysis; however, that said, it is an excellent tool for the evaluation of any change that a facility is looking at implementing. As an example, the management of change process can be embellished significantly if the proposed change includes a copy of the worksheet containing a small question set that includes the risk calculation. This would support government audits for showing the impact of the change per Process safety management of highly hazardous chemicals -- 29 CFR 1910.119(l)(1):
The employer shall establish and implement written procedures to manage changes (except for "replacements in kind") to process chemicals, technology, equipment, and procedures; and, changes to facilities that affect a covered process.
