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...

Christine Browning
The focus of most laboratory experiments and piloting operations is the development of a new, innovative chemical process or the improvement of an existing chemical process. These activities are designed to, and focus on, evaluation of the intended chemistry for the process being studied. The...

Selection of Appropriate Ignition Models for Fire and Explosion Assessments

Apr 3, 2012
Anna Qiao
A release of flammable substances can result in various fire or explosion events depending on whether there is an immediate or delayed ignition. Although developments have taken place in producing fit-for-purpose ignition models, there remain significant uncertainties, including how to identify the...

This paper will share the UK's experience of risk control for major hazards and will emphasise the key role corporate governance and leadership plays in the management of major hazard risks. The paper will outline the joint work undertaken between industry and the Health and Safety Executive in...

Improving the Performance of Established PSM Programs

Apr 2, 2012
James A. Klein
Many facilities have now implemented and maintained PSM programs for 20 years or more, but these facilities continue to have sometimes serious incidents and injuries suggesting a continuing need to improve their PSM performance. Of course, new requirements are often added to upgrade PSM programs,...

Safety System Impairments and the Need to Manage Peak Risk

Apr 2, 2012
David K. Lewis
The catastrophic incident which occurred at Bhopal is often referenced with respect to inherent safety issues. Did intermediate chemicals need to be present? Should the neighboring community start at the fence line? Although likely not as important as the above fundamental considerations, the...

Glenn Young
OSHA's National Emphasis Program (NEP) on refineries has concluded. The two most cited elements of the Process Safety Management standard (PSM - 1910.119) in the NEP were Mechanical Integrity and Process Hazard Analysis (PHA). [1] This session will focus on common problems in PHA and how to avoid...
