In baseball, a baserunner is safe when he reaches a base without being put out by various ways. While a runner is touching a base, he is usually not in jeopardy of being put out, and is thus "safe" from fielders' actions. The runner is in jeopardy once again, negating this safety, when he ceases touching the base, when forced on a force play, or when the runner commits interference. By the rules, a runner is safe when he is entitled to the base he is trying for. Umpires will signal that a runner is safe by extending their elbows to their sides and then extending their arms fully to the side. For emphasis, an umpire may fully cross and extend his arms several times to indicate safe. Verbally, the umpire will usually simply say "safe". If a close play occurs that may have appeared to be a putout, the umpire will also call a reason for the safe call, such as "he dropped the ball" or "he missed the tag".
