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.Read more

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.

OSHA Chemical NEP Panel Discussion

Mar 23, 2010
Lisa Long, Mark S. Dreux
This presentation will provide additional time for the session speakers to discuss additional aspects of the OSHA Chemical National Emphasis Program (NEP), as well as discuss additional questions and comments from the session attendees.

Evaluating Human Response to an Alarm for LOPA or Safety Studies

Mar 23, 2010
Robert J. Stack
Many LOPA scenarios have an independent protection layer (IPL) credit for operator intervention to prevent or mitigate the scenario. It is often difficult for the LOPA team or other safety teams to assess if the appropriate operator response credit is being taken. To allow a more consistent...

Burn Injury Caused by Mixing Incompatible Chemicals with Sodium Permanganate

Mar 23, 2010
Russell A. Ogle
This paper discusses the investigation of an accident caused by the mixing of incompatible chemicals, a strong oxidizing agent with a reducing agent. The exact mixture and sequence of mixing was unknown, but the materials included an aqueous solution of 40% sodium permanganate (NaMnO4) and possibly...

OSHA Refinery and Chemical NEP Findings

Mar 23, 2010
Lisa Long, Michael Marshall
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...

Hazards of Unplanned Power Outages: Implementing Appropriate Safeguards

Mar 23, 2010
Russell A. Ogle
Accident root cause investigations often may identify unplanned power outages as the cause of a catastrophic accident. Unplanned power outages can be an initiating event that leads to an emergency shutdown of a process unit. If the emergency shutdown is managed incorrectly, it can result in an...

Modular Procedural Automation Addressing the Post Recession Skills Gap

Mar 23, 2010
Maurice J. Wilkins
A procedural operation consists of a set of tasks that are conducted in a set way time-after-time to achieve a certain goal such as starting or shutting down a unit or making a product. As demonstrated by Paul McKenzie (Bristol Myers Squibb) at the WBF NA Conference 2007 in Baltimore, it could even...

Investigation of an Explosion in a Gasoline Purification Plant

Mar 23, 2010
Kees Van Wingerden
On May 24, 2007 an explosion and subsequent fire destroyed a tank farm located at a gasoline purification plant in Sløvåg, Norway. In addition to the tank farm, an office building and some neighboring tank trucks were destroyed. There were no casualties in the accident, but at least two people...

Preparing for the Chemical NEP

Mar 23, 2010
Mark S. Dreux
On July 27, 2009, OSHA issued a National Emphasis Program for the chemical industry (“the Chemical NEP”). Pursuant to the Chemical NEP, OSHA will conduct PSM inspections of numerous chemical facilities. This presentation will review lessons learned from OSHA's Refining NEP, particularly the OSHA...

Modification of Risk Using Barrier Methodology

Mar 23, 2010
Robin Pitblado
Risk assessments use frequency data mostly from generic sources, typically from the North Sea offshore environment or from process facility records mainly from Europe. As QRA's are being applied increasingly in North America and in the developing world, novel techniques are necessary to establish...

Condensation Induced Water Hammer: Principles and Consequences

Mar 23, 2010
Carlos A. Barrera
An explosion occurred in the boiler room of a food processing plant as the steam generation system was coming online after a maintenance shutdown. The explosion shattered the case of the condensate return pump fatally injuring an employee, while another employee was burned by the escaping steam...

Complying with OSHA's RNEP, CNEP, and VPP RAGAGEP

Mar 23, 2010
Chad Patschke
The OSHA Refinery National Emphasis Program (NEP) and OSHA Voluntary Protection Program (VPP) PSM Supplement ask specific questions relative to many recognized and generally accepted good engineering practices (RAGAGEP). Many of the same RAGAGEP can be expected in the planned OSHA Chemicals NEP as...

Imperial Sugar Refinery Combustible Dust Explosion Investigation

Mar 23, 2010
John Vorderbrueggen
On February 7, 2008, at about 7:15 p.m., a series of sugar dust explosions at the Imperial Sugar manufacturing facility in Port Wentworth, Georgia, resulted in 14 worker fatalities. Thirty six workers were treated for serious burns and injuries—some caused permanent, life altering conditions. The...

Objective Analysis of PSM Audit Data

Mar 23, 2010
Jerry Forest
In developing systems for Process Safety Management, compliance audits are integral with verification that practices and procedures are developed and are effective for compliance. Data collected during compliance audits is often subjective and findings are descriptive in nature. It is therefore...

An Integrated Toolkit for Addressing Human Factors Issues in Process Safety

Mar 23, 2010
David Embrey
This paper describes an integrated toolset, called the Human Factors Workbench, which addresses the proactive and reactive control of human error in process operations. It is a practical application of the tools described in the CCPS publication: ‘Guidelines for Preventing Human Error in Process...
