Process Safety Competency

Developing, sustaining, and enhancing the organization’s process safety competency is one of five elements in the RBPS pillar of committing to process safety. Resources in this section relate to what process safety competency means, the attributes of process safety competency, and how organizations might enhance their own competency. Start by reading an Introduction to Process Safety Competency and then explore the resources listed below.

Dust Explosions: Case Study of Dryer Explosions and Poor Explosion Vent Design

Apr 4, 2012
Scott G. Davis
Four recent explosions occurred in a single burner, recirculating solids ring dryer. The dryer was equipped with a recirculating fan, a burner section, a section to introduce the solids, a ring duct, a pre-separator and four cyclones. Seven explosion doors were also used to protect the integrity of...

Impact of Guidelines for Independent Protection Layers and Initiating Events

Apr 4, 2012
J. Wayne Chastain
Layers of Protection Analysis (LOPA) was introduced about 15 years ago as a simplified risk assessment method between HAZOP (Process Hazard Analysis [PHA]) and quantitative risk assessment (QRA). This introduction was timely; LOPA was quickly adopted world-wide. The rules for independent protection...

The Structured What If/Checklist A New Twist On An Old Approach

Apr 3, 2012
C. Curtis Clements
The purpose of Process Hazards Analysis (PHA) is to identify and understand the hazards associated with the process being reviewed, to understand the potential resultant hazardous events, and to prevent those events by identifying all the potential routes to those events and ensuring that adequate...

An Introduction to Assessing Process Hazards

Apr 3, 2012
Seshu Dharmavaram
A surprising number of process incidents occur due to a lack of general understanding of process hazards and lack of basic hazards assessment, subsequently resulting in the absence of or inadequate Process Hazards Analysis (PHA) to provide appropriate safeguards for minimizing process risks...

Continuing Our Process Safety Management (PSM) Journey: How Time and Technology Have Helped Change the Public's View (A Case Study for Where We Are Today and Where We Can Go Tomorrow)

Apr 3, 2012
Bruce K. Vaughen
This paper briefly explores the history of basic PSM principles, first describing a historical view of how PSM developed into today's PSM Elements. Then this paper covers a proposed direction for PSM's future that may help address the changing nature of the public's view of the chemical industry –...

Challenges in Applying PSM to Production Pilot Plants & Laboratories

Apr 3, 2012
Bruce D. Bullough
The CordenPharma Colorado, Inc. (CPC) site in Boulder includes at least eight production facilities. The majority (six) are production laboratories and pilot plants, with synthesizers and vessels of a few liters to a few thousand liters. All of the production process systems are connected to at...

Process Safety - Management or Leadership?

Apr 3, 2012
Charles J. King
Process Safety Management is often presented as technically complex, requiring a large staff of engineers and specialists with an array of tools and techniques that appear to grow in intricacy and sophistication year by year. Large companies are generally well positioned to operate in this arena –...
