What is a dead hand, and who can call it?
A dead hand is a hand that can no longer legally win, most often because of a wrong tile count or an exposure that matches no line on the card. You cannot call your own hand dead. Another player has to call it, on evidence the table can see, and once the call stands you stop drawing, stop discarding, stay silent, and pay the winner at the end of the hand.

What actually kills a hand
The common causes are mechanical rather than mysterious. Holding the wrong number of tiles after East's first discard, fewer than thirteen or more than fourteen, is the most frequent one. So is an exposure that is not a legal group of identical tiles, or a set of exposures that fits no line on the current card between them.
There are others, and they share a family resemblance. Exposing anything at all on a concealed line. Discarding before you drew. Drawing out of turn, or from the wrong wall, or from the wrong end of a wall, once the tile has been racked. Making a Joker exchange before you have drawn and racked. Each of them leaves the hand in a state the rules cannot resolve, so the hand is finished.
One more is quieter and catches good players: an unwinnable hand, where your exposures show what you need and three or more of the four tiles that could finish it are already sitting in the discards or on somebody's rack. That hand cannot come in, and once the table can see as much, it can be called.
Only somebody else can say it
A player may never declare their own hand dead. That is a rule and not merely etiquette, and the reason is the situation it would create: announcing your own mistake tells the whole table what you were building and how your rack is shaped, which is information nobody is entitled to.
So if you realize mid hand that you are in trouble, say nothing. A hand that is in fact dead but that nobody has called keeps its seat and keeps playing. It draws, it discards, it plays defense, and it cannot win. You must not announce it, and ideally nobody ever knows. You cannot be disqualified by something only you can see.
The evidence has to be visible
A hand may be called dead from the exposures, from the discards and from the tile count, and from nothing else. Counting how many tiles somebody is holding is entirely allowed, needs no look at the faces, and settles a wrong count in about a second.
What you may never do is guess. A hand with nothing exposed cannot be called dead from the discards, because nobody at the table knows what that player is collecting. Only a hand that has shown something can be checked against the card and found impossible.
If the call is disputed
Any player may call another hand dead at any time, even out of turn, and a question or a pointed comment about whether a hand is dead counts as the challenge. The conversation belongs to the challenger and the challenged. Everybody else stays out of it.
The challenged player may accept it and stop, or may disagree without revealing a thing, in which case play simply continues and the matter is settled when the tiles come up at the end of the hand. Whoever was wrong at the moment of the challenge pays the other player fifty, on top of whatever is owed to the winner. A wrong challenger pays. A wrong denier pays. That symmetry is what keeps the challenge from becoming a free move.
Once a hand is confirmed dead, that player is out for that hand only. No draw, no discard, no call, no win, and silence until the end, and then the full value of the winning hand goes to the winner. The next deal starts everybody fresh.
Name the violation yourself
Most dead hands come from a short list of ordinary mistakes. Penalty Identifier shows you the table and asks you to name what went wrong.
