As suggested by tutor Amber, I went to seek a sequence in the form of airline safety cards. There are many available to view on the web, but this brightly coloured, and simplistic example from Australian airline, Qantas, was certainly my favourite.
Many examples that I saw were quite dull, and heavy-laden with text and instructions. Of course, in the case of an emergency, you are hardly likely to want to partake in a "leisurely read", so Qantas' illustrative step-by-step guide is brilliant for many circumstances.
The pictures are detailed enough to prevent any confusion, and without text they transcend any language (as flights are so often multi cultural), and, also, the bright colour means that, in the case of emergency, it should be easy to find, in combination with their usual location in easily accesible areas.
