Process Safety Boot Camp

Instructor-led (classroom) Course
This intensive 4-day course is also offered periodically throughout the year to the broader chemical engineering public. Taught jointly by process safety veterans with decades of experience at major companies from the process industries, the course is highly interactive.

Center for Chemical Process Safety (CCPS)

CCPS was established in 1985 to focus on engineering and management practices that can prevent and mitigate catastrophic accidents involving release of hazardous materials. CCPS is supported by sponsors in the chemical and hydrocarbon process industries and active worldwide via conferences, books, databases, education, research, and more.

Good Engineering Practices - Inspection and Test Frequencies

Mar 15, 2011
Richard Prugh
The "Process Safety Management" standard of the Occupational Safety and Health Act [OSHA] requires that "The frequency of inspections and tests of process equipment shall be consistent with applicable manufacturers' recommendations and good engineering practices, and more frequently if determined...

Risk Assessment of a Propane Storage Sphere: Maintain or Decommission?

Mar 15, 2011
Russell A. Ogle
Ten years ago, the authors were asked to assist a utility with a risk management decision. Specifically, the utility was considering whether they should maintain or decommission an 800,000 gallon propane storage sphere. The 30-year old sphere was the fuel storage vessel for a peak-shaving power...

The Challenge to Implement and Maintain An Effective PSM Program

Mar 15, 2011
Ken Hanchey
While researching to develop responses to help a client respond to OSHA citations, we discovered a presentation to the same industry segment from 1997; we could change the date and present the same presentation today. OSHA is still finding the same gaps as 14 years ago. Chemical plants generally...

A Frequency Based Approach to Hole Size Selection for Consequence Analysis

Mar 15, 2011
Mike W. Stahl
When performing a consequence based facility siting study, it is often necessary to choose a criteria for the maximum credible hole size that is the source for a hazardous release. Many companies choose a variable hole size using a fraction of the pipe size to determine the source hole. Other...

An Update on OSHA's PSM National Emphasis Programs

Mar 15, 2011
Lisa Long
Since 2007, OSHA has initiated two major National Emphasis Programs (NEPs) in process safety. The Petroleum Refinery Process Safety Management NEP (Refinery NEP) was effective on June 7, 2007; the PSM Covered Chemical Facilities NEP (Chemical NEP) was effective on July 27, 2009. This presentation...

QRA Method for Land-Use Planning around on-Shore Oil and Gas Facilities

Mar 15, 2011
Eelke S. Kooi
In the Dutch legislative context, facilities that handle or store large amounts of hazardous substances must carry out a quantitative risk analysis (QRA) for land-use planning purposes. The outcomes of the QRA determine the kinds of activities that are tolerable in the surroundings of the facility...

Acid Release From Catalyst Tanks

Mar 15, 2011
R. Wayne Garland
This is the story of how the cumulative effects of several seemingly innocent changes to a catalyst system resulted in a near miss Process Safety incident. Several aspects will be discussed including cumulative effects of multiple changes to the system, identification of potential scenarios in...

The Obvious-to-Obscure Process Safety Checklist for Plant Engineers

Mar 14, 2011
John T. Perez, Simon R. Layton
The recent process safety performance of the energy industry has led to scrutiny of industry and company-specific process safety standards, guidelines, and best practices. Several elements of process safety focus directly on the knowledge-base and experience of a facility's workforce. Plant...

LOPA – Validating Human IPLs and Ies

Mar 14, 2011
Bill Bridges
Layer of Protection Analysis (LOPA) is a simplified risk assessment method that provides an order of magnitude estimate of the risk of a potential accident scenario. Humans can be the cause on an accident scenario (the Initiating Event [IE]) or human can serve as an independent protection layer (...

Portfolio Risk Management for Process Safety

Mar 14, 2011
Georges Melhem
A majority of PSM tools and risk methodologies are focused on risks at individual sites or process units. For example, PHA risk ranking matrices are frequently cast in terms of consequences that occur at a plant level. However, corporations with many operating facilities need to find ways to...

Using the HAZOP Study and LOPA to Generate Ideas for Inherently Safer Designs

Mar 14, 2011
Steven T. Maher
Fundamental changes in a chemical process are most cost-effective at early stages of a design, and specific Inherently Safer Design evaluations are frequently performed at these early stages to identify fundamental improvements that can signicantly decrease the magnitude of the consequences...
