Posted By FJ Not really answering the specific question (I do not believe there is but am interested to be proved wrong). What I do want to chip in is what has been done in this large office block. All the possible routes to fire exits are marked with red carpet tiles- so in case of a fire/power cut/poor visibility if you find a red carpet you know that following it will get you to an exit- like the strips you get on aircraft I suppose.

Posted By GT Barry, There is an International Standard for demarcation Aisles, Walkways, & Storage etc NOSA used to have and it is adopted by BSC in their six star audit I believe. I will try an dig it out for you later, but you are on the right track I believe without referencing the documentation that yellow and black chevron is used to indicate a strike into hazard, red as you say are danger areas, working areas Blue? and green or grey for aisles, walkways. Fire Points, Electrical switch gear etc was also to be indicated ( red and white lines??) hope this helps be patient with me hahaha GT
