If you or someone have just suffered a burn and you are in panic to
apply cold water, the dominant right hand should be closer to the cold tap.

However if you are left handed, or have suffered a burn to the right
hand, than it will take just a little longer to register a work around
to this ;-)

I once almost scalded my hand by using a mixer tap where the tap on the
left had a red band around it so I turned on the tap on the right
thinking it would be cold and very hot water came out. Turned out the
"tap" on the left was actually the temperature select for the
thermostatic valve.
