Crime scene cleanup is a term applied to cleanup of blood, bodily fluids, and other potentially infectious materials (OPIM). It is also referred to as biohazard remediation, because crime scenes are only a portion of the situations in which biohazard cleaning is needed. Such incidents may include accidents, suicides, homicides, and decomposition after unattended death. It could also include mass trauma, industrial accidents, infectious disease contamination, animal biohazards (e.g. feces or blood) or regulated waste transport, treatment, and disposal.
