Hazard Identification and Risk Analysis

A thorough Hazard Identification and Risk Analysis, or risk, system is the core element in the RBPS pillar of understanding hazards and risk. The chapter describes the meaning of risk for RBPS purposes, the attributes of a risk system, and the steps an organization might take to implement a robust program for identifying hazards and analyzing risk. Introduction to Hazard Identification and Risk Analysis

Guidelines for Identifying and Mitigating Thermal Hazards of Sustainable Materials

Mar 14, 2011
Delmar R. Morrison
Sustainable materials and technologies (a.k.a. ?Green?) are those that are ?delivered with progressively less negative impact upon the Earth.? Thermal hazards such as self-heating, thermal runaway, fires, and explosions may be associated with a particular sustainable material or process technology...

The Buncefield Explosion: Were the Resulting Overpressures Really Unforeseeable?

Mar 14, 2011
Jérôme R. Taveau
On Sunday 11 December 2005, a severe unconfined vapour cloud explosion followed by several tank fires occurred at the Buncefield oil storage depot in England, causing widespread damage to homes and businesses surrounding the site, hopefully without any victim. The damage caused by the resulting...

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 (...

A Work Process for Revalidating LOPAs and Other Risk Analyses

Mar 14, 2011
Timothy J. Wagner
The Chemical Process Industry (CPI) has long recognized the necessity of periodically revalidating Process Hazard Analyses (PHAs), such as Hazard and Operability Studies and What-if analyses. CCPS has published a book which describes this work process titled Revalidating Process Hazard Analyses...

On the Potential of Mitigating Vapour Cloud Explosions Using Flame Inhibitors

Mar 13, 2011
Kees Van Wingerden
Very few measures are taken to mitigate the possible consequences of vapour cloud explosions. The main attention is given to prediction of the consequences, which is used to consider strengthening structurally or re-locate occupied buildings such as control rooms. However little is undertaken to...

Using LOPA for Sil Assignment: A Tale of Two Plants

Mar 13, 2011
Michael S. Schmidt
Two plants operated by the same company have ?identical? ammonium nitrate (AN) solution pump installations. Yet the LOPA teams concluded that the safety instrumented functions to protect those pumps needed different safety integrity levels (SILs). Despite the similarity of the installations, the...

Safety Studies for Reformatsky Chemistry In a Meso-Scale Continuous Process System

Mar 13, 2011
Gabriel Loh
The production of fine chemicals and pharmaceuticals has been traditionally achieved via batch processes. More recently, there has been interest in using multiscale (meso- and micro-) reactors for the production of these fine chemicals and pharmaceuticals. These efforts in process intensification...

Incident Investigation – Addressing the Worst That Could Have Happened

Mar 13, 2011
Samuel A. Rodgers
Incident Investigation techniques typically start with a detailed description of the actual consequence and work backward toward the root causes. A lot of time is spent to qualify and quantify the actual consequence so as to appropriately apply resources to prevent recurrence. A frequent outcome of...

Kinetic Modeling of the Reactions Involved in the T2 Explosion

Mar 13, 2011
Ronald J. Willey
The runaway reaction at the chemical preparation facility called T2 laboratories in Jacksonville, Florida on December 19, 2007 is analyzed. The approached involved estimating kinetic parameters based on temperature time traces presented in the CSB final report for ARSST (Advance Reactive System...

Inherently Safer Reactor Design for Complex Reactions Based On Calorimetry Studies

Mar 13, 2011
Alba Lucia Pineda
A number of reactive processes of the agrochemical, fine-chemicals and pharmaceutical industries involve thermally unstable and/or toxic reactants, products or intermediates, for which the chemistry, thermochemistry and thermodynamic properties are barely known. They frequently employ multipurpose...
