Process Safety Cards

Process Safety Cards have a simple goal – to improve the awareness of less technical personnel to potential Loss of (Primary) Containment (LoC) scenarios and increase their vigilance to such events & their potential causes so they can be promptly addressed.

We do that with memorable images representing typical events.

Users or ‘Players’ are encouraged & helped to learn & apply the principles using this simple mnemonic:

  • REMEMBER Events
  • RECOGNISE Threats
  • RESPECT Barriers
  • REPORT Concerns

Thereafter, there is an obligation on the duty-holder to:

  • RESPOND to Feedback
  • RECOVER Protection

Visualization is used to get and keep the workforce onboard with the process safety mission by challenging them with these simple questions:

  • Do you UNDERSTAND what can wrong i.e. HAZARDS & LoC Events?
  • Do you KNOW what the systems are to prevent this from happening i.e. BARRIERS?

It is anticipated that, not only will site personnel benefit from these cards, 3rd parties e.g. contractors, visitors or others who may fall outside company initiatives or training can become better informed on the hazards, threats & controls that they may be involved with or impacted by. As the workforce ages and critical work is outsourced, duty-holders may rely more and more on those outside their organisation to sustain asset integrity – how well informed are they?


Scenarios are divided into the following ‘suits’:


Containment is lost via an open route to atmosphere
External impact
Failure beyond design conditions/envelope (over-stress)
Failure within conditions/envelope (under-strength)

These provide simple visual prompts to remind or inform “players” of the potential for LoC:


Scenario summaries are presented as separate pages with one LoC on each sheet. They include typical (suggested) Causes for the loss and visual representations of the scenarios in bowtie format, for example:

Visualisation aims to help “players” recognise Threats and respect Barriers e.g. ensure their actions or inactions do not disable, degrade or delete prevention measures associated with each LoC event.
