ProjectAims and Description
Unwanted Polymerization
complete
Started: March 2022
Chair: Marek Moraczewski
Hydrocarbons with double bonds are known to undergo radical polymerization to form solid plastics from liquid or gasses. This polymer can be formed at unwanted places and form restriction and severe blockage of piping. Conjugated dienes such as 1,3 butadiene and isoprene or vinyl aromatics such as styrene can form “popcorn polymer” in mostly gaseous and occasionally liquid phase. The growth of “popcorn polymer” may exert enough pressure to rapture piping, heat exchanger shells, valve bodies and other metal equipment.
The Working Group focused on butadiene and isoprene and in addition other polymerising chemicals can be included (like propylene, ethylene and Styrene Monomer)..
Leadership & Organisational Effects
complete
Started: 2020
Chair: Steve McGrady
The basis for good process safety is Leadership and Organization. A strong process safety culture requires a strong leadership and an organization with the right specialists. How do you create such leaders, what criteria helps to select them? What are characteristics of effective process safety organizations? 
The EPSC WG produced a sheet with access to a leadership development program. It is based on real cases with a role play that can be provided by the named consultants.
Human Performance
complete
Started: 2018
Chair: Tijs Koerts / Hans Schwarz
Members of this Working Group investigated the role of human error on serious incidents and described best practices to improve.

complete
Started: Dec 2018
Last met: Sept 2020
Chair: Dirk Roosendans / Tijs Koerts
 

The EPSC Working Group on Process Safety Fundamentals drew up a set of safe operational principles to avoid incidents with hazardous chemicals. The current collection of EPSC process safety fundamentals addresses 18 typical hazardous operational situations.

Semi-Quantitative Risk Evaluation Methods
complete
Started: 2014
Last met: April 2018
Chair: Ulrich Hoercher
 This group will share experience in using semi-quantitative risk evaluation and risk matrix methods to determine their general suitability for process industry in Europe.
Inherently Safer Design
complete
started 2014
Last met September 2015
leader: Konrad Fischer
EPSC staff: Theo Reindorp
The principles of inherently safer design are generally well understood, giving a preference for processes in which a hazard is limited or not present. Most companies follow principles of ISD, but with varying degrees of experience in the methods. EPSC is motivated to move the concept on by members sharing their methods, success stories, barriers and how they may be overcome, and assessment methods for degree of implementation and conformance with the principles.
Corrosion Under Insulation
complete
started 2013
Last met March 2015
leader: Paul de Bruyn
EPSC staff: Lee Allford
Undetected corrosion of assets has been a primary cause in incidents and near misses with potentially high consequence. The objective of this working group is to share knowledge and experience in the early detection of corrosion under insulation with an emphasis on current and emerging inspection technologies.
Process Safety Indicators
complete
started 2008
last met April 2015
leader: Piet Knijff
EPSC staff: Lee Allford
This group works towards global or Europe-wide standard forms for reporting process safety performance through incident data. The group also serves to provide guidance on leading indicators of measurably good safety behaviours.
Risk Acceptance Criteria
complete
started 2013
last met July 2014
leader: Klaus-Juergen Niemitz
EPSC staff: Christian Jochum
There is no common understanding of how ALARA, ALARP and other risk acceptance criteria have to be applied in cases of many facilities operating within a single park. Neighbouring facilities may belong to different legal entities, and the interfaces between these organisations have to be managed. The objective is to analyse how these problems are handled by EPSC members and to develop guidance for best practice.
Enhancing Hazard Identification
complete
started 2012
Last met November 2012
leader: Thomas Wolff
EPSC staff: Richard Gowland
The Atypical Scenarios group which reported in mid 2012 suggested that a greater role should be played by Process Hazard Analysis and other procedures. There is general agreement that enhancing Hazard Identification and incorporating the identified hazards into Risk Management is a worthwhile task. Identifying hazards earlier in the life cycle of a new project may be of benefit, but the techniques would also be applicable to existing facilities.
Risk Assessment Methods
complete
started 2013
last met June 2013
leader: Eberhard Guntrum
EPSC staff: Richard Gowland
Risk assessment is a requirement under the Seveso directive, but multiple methods are possible and specific requirements can vary by country. This group compares risk assessment methods to document their benefits and pitfalls, and to examine modern developments in these approaches.
Global Consistency
complete
started 2013
last met March 2013
leader: Ulrich Hansen
EPSC staff: Richard Gowland
The objective is to analyse how Process Safety Management can be consistently applied across an international organisation, taking into account different legal systems and legislative requirements, different cultures and languages, degrees of seperation from organisational leadership, and varying physical environments.
Scenarios
complete
started 2011
last met October 2011
leader: Hans Schwarz
EPSC staff: Richard Gowland
Scenarios refers to the development and evaluation of chains of events during a hazard analysis and risk assessment procedure. The Scenarios group is working to identify deficiencies in risk assessment that may be resolved with enhanced scenario development. "Worst case" scenarios are one such example, with risk assessment methods such as HAZOP giving more focus to higher probability events, scenario evaluations may be used to review less likely but higher consequence events.
Ageing Assets and Facilities
complete
started 2010
last met October 2011
leader: Eberhard Guntrum
EPSC staff: Richard Gowland
Ageing assets and facilities are a prominent current topic following recent attention to the subject by authorities in France. Ageing has been defined by CAs as deterioration of plant and equipment by gradual damage. This group examines the management of ageing equipment and planning for sustainable maintenance.
Process Safety Competence
complete
started 2010
last met August 2011
leader: Paul Delanoy
EPSC staff: Christian Jochum
This group studies the methods by which a company can maintain high levels of competence, through hiring, training, managing experience and awareness of critical skills.
Safety Critical Equipment
complete
started 2009
last met October 2011
leader: Dirk Roosendans
