With the children I work with, once they have a melt down thats it, their request are denied untill they calm down. Can't reason with them when they go there. And if the request they want can't be possible and they melt down, oh well. Alot of times they go to this power struggle manipuleted mode that we just can't help when with, they have therapist for that. So then there are consequences plain and simple. But before we go there, with the therapist we work out a plan on how to avoid them and what the childs responsiblilty is to prevent them, and how to calm themselves down before it hits. And if it's unavoidable how that child can pull themselves out of it. Because sometimes nomatter what we do, there's going to be one. If they lash out and hurt someone one, or themselves, if they become distructive, or start awearing, then they get in trouble. they know this. But they are allowed to go running, they can hit their pillows, they can tear paper, go to their rooms and yell if they want to, exercise, write,play music, just depends on the child. One of my boys would take a long bubble bath, another one would clean. One size just dosn't fit all. But they are not allowed to make others a victim of their melt downs. Sometimes they just need to talk, and they can vent. But they have to be appropriate. they learn, takes along time but they do. Hope this helps.
