Human Error

The Adventures of Joe Soap & John Doe

We are honoured to have been granted permission by the family of the late, great Professor Trevor Kletz, OBE, FREng, FRSC, FIChemE to reproduce his work.

Cartoons from his IChemE Book “An Engineer’s View of Human Error” have been presented on familiar playing cards:

Joe Soap makes frequent mistakes – he takes the wrong action as he has not been told what is the right action:

John Doe makes the little slips we all make from time to time. We could tell him to be more careful…

… or we could make simple changes to plant design or methods of operation to remove opportunties for error.

Try to change situations, not people

Trevor Kletz

A key message is that images need to be refreshed or replaced regularly, otherwise they become part of the unnoticed background.

Using cards in a variety of environments or engagements (both with your own personnel & 3rd parties) should ensure that these messages do not become stale.
