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.

Use this checklist-based technique of process-hazard analysis (PHA) to identify and assess potential dust hazards and to evaluate safeguards that can mitigate risks.
LIKELIHOOD of IGNITION of RELEASED FLAMMABLES: CCPS Book—Scope, Status, and Relationship to Other CCPS Books
Mar 15, 2011
Mike Moosemiller
When a flammable material is released from process equipment, the result may be a fire, an explosion, or the release may simply dissipate with no apparent effect other than a minor environmental impact. Depending on the circumstances, the probability of ignition can range from 0 to 1. For anyone...
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...
What to Do When Nothing Has Happened?

Raymond "Randy" Freeman
Often during a Layer of Protection Analysis (LOPA) or a Quantitative Risk Analysis (QRA) study, historical information indicates no occurrences of a particular undesired event in the plant or system. The analyst must decide on an appropriate measure of the frequency of the undesired event. The...
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...
Application of the NFPA 654 Dust Layer Thickness Criteria – Recognizing the Hazard
Mar 14, 2011
Samuel A. Rodgers
This paper is an overview of the NFPA 654 layer thickness criteria, including the 2010 TIA, and potential misinterpretations that could result in failure to recognize the hazard. Potential misinterpretations include allowing excessive floor area coverage, failure to account for layers thicker than...
