Know Your Onions

We’ve been commissioned to develop a set of cards based on the Initiating Events (IE) and Independent Protection Layers (IPL) from the AIChE – American Institute of Chemical Engineers CCPS LOPA Book (Layer of Protection Analysis: Simplified Process Risk Assessment) which has been industry best practice for over 20 years. The following references have been operationalised &Continue reading “Know Your Onions”


We have now completed our 1st deck of Incidents Cards based on 52 famous (and less well known) Process Safety (Loss of Primary Containment) events researched, evaluated & summarised by Peter Marsh of XBP Refining. These have been peer reviewed by members of the IChemE Safety & Loss Prevention Special Interest Group. Their work isContinue reading “Incidentally”

Don’t Gamble with Safety

Inspired by playing cards created by ICI and Esso, we designed our decks to be informal as well as informative, fun as well as functional to provide Users (‘Players’) with a familiar format to learn through gamification e.g. to play ‘conventional’ card games with their teammates or co-workers. However, we recognise (and respect) that differentContinue reading “Don’t Gamble with Safety”

Simple Layer of Protection Exercise The CCPS book “Layer of Protection Analysis: Simplified Process Risk Assessment” has been the definitive reference for performing Layer of Protection Analysis (LOPA) since it was published in 2001. LOPA is a simplified form of risk assessment which typically uses order of magnitude categories for Initiating Event Frequency (IEF), ConsequenceContinue reading “SLOPE”

Managing the Safety of Processes

Our Process Safety Management (PSM) cards have been updated to represent a full set of human characters to act as a reminder that we need people to execute the processes and procedures within PSM frameworks. Cards are organised into the following topics: Organisation Analysis & Implementation Operation & Maintenance Excursions & Modifications The PSM manualContinue reading “Managing the Safety of Processes”

Incident Infographics

Today marks another anniversary of the BP Texas City Refinery explosion of March 23rd 2005. There is no doubt that Incident Investigation reports provide valuable insight into the immediate and root causes of major accidents like this, however can you really digest & communicate all the key messages and apply the lessons which have beenContinue reading “Incident Infographics”

CHASE – Cyber Challenges & Controls

Hybrid warfare is now (sadly) a reality, and the threat of digital attacks has placed national & local infrastructure assets on heightened alert, however there is a wealth of information available to help evaluate your cyber security vulnerabilities & measures. The UK Health & Safety Executive (HSE) operational guidance (OG-0086) includes two clear statements associatedContinue reading “CHASE – Cyber Challenges & Controls”

VESTA – Ignition Insights

THE UK Health & Safety Laboratory conducted research [HSL0609] into ‘Unidentified Ignition Sources of Unplanned Flammable Releases‘ and found that ” … following investigations into major accidents that had a release and an ignition, about 60% of those incidents did not have an ignition source identified by the investigation” – so if you don’t knowContinue reading “VESTA – Ignition Insights”
