Explosions in Transformer and Circuit-Breaker Tanks Due to Arcing Events

Apr 4, 2012
Timothy L. Morse
Industrial transformers and circuit breakers operate with large voltage differences between current-carrying internal components and the grounded tank walls. A breakdown in the dielectric strength of the insulating oil in the tank due to contamination or other causes can lead to the formation of an...

International Comparison on the Application of Societal Risk Criteria

Apr 4, 2012
Robin Pitblado
Quantitative risk assessment is now a common tool used for planning and approval of high risk process facilities globally. The initial focus was towards individual risk contours as these were easier to apply and communicate, but a number of regulators and companies also wish to see societal risk...

Dust Explosions: Case Study of Dryer Explosions and Poor Explosion Vent Design

Apr 4, 2012
Scott G. Davis
Four recent explosions occurred in a single burner, recirculating solids ring dryer. The dryer was equipped with a recirculating fan, a burner section, a section to introduce the solids, a ring duct, a pre-separator and four cyclones. Seven explosion doors were also used to protect the integrity of...

Flash Fire From a Hot Combustible Liquid

Russell A. Ogle
A truck driver loading a tanker was fatally injured in a flash fire. The accident occurred at the loading rack of a petroleum refinery. The truck driver was on top of the tank trailer loading a liquid petroleum byproduct material similar to asphalt through an open hatch on the trailer. The material...

Working Under Pressure (How do you manage pressure hazards?)

Apr 4, 2012
Dr. Angela E. Summers
Industry is increasingly moving towards utilizing High Integrity Protective Systems (HIPS) to reduce flare loading and prevent the environmental impact of pressure venting. HIPS are becoming the option of choice to help alleviate the need to replace major portions of the flare system in existing...
