Abstract
It is shown that a trapped surface can be extended, in a locally area-preserving fashion, to a three-cylinder that is everywhere spacelike, provided it encounters no singularities in its development. Thus the interior of a regular, area-preserving, initially trapped surface is permanently sealed off from causal influence on the exterior world.Keywords
