  We study the perturbation induced by a slowly rotating massive object as it
passes through a Rindler horizon. It is shown that the passage of this object
can be approximately modeled as Delta\,function type tidal distortions hitting
the horizon. Further, following the analysis presented by Amsel, Marolf and
Virmani related to the issue of the validity of physical process first law, we
establish a condition on the size of the object so that this law holds for the
Rindler horizon.
