Social HAZOP At Oil Refine Industry

Apr 2, 2012
Salvador ¡vila Filho
Introduction Maintenance of process safety in the industry several tools are used such as Risk Analysis, Failure mode and events Analysis (FMEA), a Hazard operability analysis (HAZOP), Quantitative Risk Analysis (QRA), and Mapping Risk. Each tool or technique, if used at the right time can prevent...

Explosion Hazards of Multicomponent Combustible Gas Mixtures

Apr 2, 2012
Alfonso F. Ibarreta
Laminar and turbulent premixed flame burning velocities are two parameters that are sometimes needed to evaluate explosion hazards. There is ample information in the literature regarding the burning velocities of most common ignitable gases and vapors in air. Little information, however, is...

The CCPS Reactivity Evaluation Software Tool

Apr 2, 2012
Edward M. Davis
Incidents involving uncontrolled chemical reactions continue to result in injuries, fatalities and economic loss and harm in industry. These incidents are often the result of not identifying or understanding the chemical reactivity hazards involved in storage, mixing or processing operations. The...

Guidelines for Engineering Design for Process Safety, 2nd Edition

April, 2012
The book focuses on process safety issues in the design of chemical, petrochemical, and hydrocarbon processing facilities. It discusses how to select designs that can prevent or mitigate the release of flammable or toxic materials, which could lead to a fire, explosion, or environmental damage.

Exposing the Blurry Lines Between Personal Safety and Process Safety Education

Oct 17, 2011
Delmar R. Morrison
Chemical engineering curricula have long been focused on instilling the fundamentals of chemical engineering science in undergraduates and advancing the state of the art through postgraduate study. Unfortunately, a comprehensive focus on safety has never been in the core of the chemical engineering...

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...

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...

PSM Metrics Impact on Process Safety Culture

Mar 15, 2011
Bill Patton
Several years ago our facility recognized the need to expand from a PSM Program managed by a small group to a PSM Culture owned by the full facility. Development and implementation of effective and consistent PSM metrics were utilized to achieve the following: (1) Set the vision for a PSM Culture (...

Methods for Precluding the Existence of a Dust-Explosion Hazard

Mar 14, 2011
Richard Prugh
The "generic" standard for preventing fires and explosions involving combustible dusts is the National Fire Protection Association publication NFPA 654. In this document, fifteen of the requirements are prefaced with the phrase "if an explosion hazard exists", and an additional four requirements...
