Just print off, laminate and hole punch the visuals in the corner. String up all the visuals you use regularly and put them on a lanyard. You could also store these on a key chain or id holder and attach to your belt loop. They are always with you and easy to point to when needed.
Here are the visuals included:
M.Y.O.B (Mind your own Beeswax!)
take a break (person going from red zone to green zone)
eyes on speaker
size of problem? (small, medium, large)
