Conduct an Effective Incident Investigation

Frederick T. Dyke
Information that can reveal the root cause of an incident resides in many places — within the plant or process unit, in control rooms and offices, and even in witnesses’ minds. Here’s how to find the data and conduct effective witness interviews.

Reduce Thermal Risk in Industrial Synthesis

Richard C. Wedlich 
Knowing the safe operating conditions for a reaction allows us to select appropriate safety measures and thereby lower both the likelihood and the severity of a thermal runaway.

Properly Purge and Inert Storage Vessels

George R. Kinsley Jr.
Inert gases are used to prevent fires and explosions in the vapor spaces of equipment. Correct selection of oxygen concentration and inert gas flow rate are critical to ensuring safety.

Tackling the Human Challenges of Facility Security

Dennis A. Attwood, Bill Effron
The increased complexity of security systems may come at the expense of the user. Thus, they must be designed to match their operators' capabilities and limitations.

Consider Natural Hazards in Process Safety Management

Frank F. Liserio Jr.
Incorporating hurricanes, earthquakes and other forces of nature into an integrated process safety management (PSM) program can enable you to effectively identify these hazards and manage the risks.

Remember Hand Protection

Laura Randall
Setting up a hand-protection program involves understanding the hazards, choosing the appropriate glove, training personnel on glove use, and ensuring that employees use their gloves properly.

What Pressure Relief Really Means

Back To Basics
Brian D. Kelly
Poor design, inadequate maintenance, and improper operation can all lead to mechanical failure. The basic concepts of pressure relief, when understood and applied properly, can help prevent this failure

Designing Multiple-Diameter Relief Piping

John Garvin
Most design methods consider a single pipe diameter. Here's how to evaluate multiple-diameter systems and to calculate conservative single-pipe representations.

Guidelines for the Management of Change for Process Safety

March, 2008
Guidelines for the Management of Change for Process Safety provides guidance on the implementation of effective and efficient Management of Change (MOC) procedures, which can be applied to improve process safety. In addition to introducing MOC systems, the book describes how to design an initial...

Guidelines for Performing Effective Pre-Startup Safety Reviews

March, 2007
This book provides guidance to those with responsibility for scheduling and executing a Pre-Startup Safety Review (PSSR). It outlines a protocol and tool for use by project or turnaround teams, to effectively and efficiently schedule and execute a PSSR. Integrates PSSR throughout the project/...

Safe Design and Operation of Process Vents and Emission Control Systems

March, 2006
Process vent header collection systems are subject to continually varying compositions and flow rates and thus present significant challenges for safe design. Due to increasingly demanding safety, health, environmental, and property protection requirements, today's industrial designers are faced...

Guidelines for Chemical Process Quantitative Risk Analysis, 2nd Edition

October, 1999
Chemical process quantitative risk analysis (CPQRA) as applied to the CPI was first fully described in the first edition of this CCPS Guidelines book. This second edition is packed with information reflecting advances in this evolving methodology, and includes worked examples on a CD-ROM. CPQRA is...

RELEASE: A Model with Data to Predict Aerosol Rainout in Accidental Releases

March, 1998
This book documents CCPS's Aerosol Research Program to develop a model to predict liquid rainout from release of a pressurized, liquefied gas--and, hence the residual amount of material in a vapor cloud, which may be greater than the amount calculated from an enthalpy chart. RELEASE predicts the...

Dow's Fire & Explosion Index Hazard Classification Guide, 7th Edition

June, 1994
This popular safety best-seller is designed to help the user quantify the expected damage of potential fire and explosion incidents in realistic terms, identify the equipment likely to contribute to the creation or escalation of an incident, and communicate the fire and explosion risk potential to...

Minimize the Risks of Flammable Materials

Back To Basics
Daniel A. Crowl
Flammable materials can cause fires and explosions if they are not handled properly. Understanding these materials and the risks they pose is the first step to mitigating fire hazards.

Decoding Safety Data Sheets

Ronald J. Willey
A safety data sheet holds a wealth of information that can help you safely and effectively handle chemicals in the lab, at the pilot scale, and on the production floor.

The Case for Double Mechanical Seals

Back To Basics
Jack Berg
Using double mechanical seals as part of thermoplastic pumps can prevent costly downtime and environmental damage.

Nitrogen — Hazard and Safeguard

Process Safety Beacon
This Beacon is not focused on a single incident, but on incidents that continue to occur across industry — nitrogen asphyxiation.

Use Nitrogen Safely

Dennis Croll, Paul Yanisko
Understanding the potential hazards and taking the proper precautions will allow you to reap such benefits as improved product quality and enhanced process safety.

An Engineer’s Guide to Management of Change

Back To Basics
R. Wayne Garland
Using a formal change procedure promotes safe operations and prevents injuries and deaths, and it will also favorably impact the bottom line.
