罪案現場
Crime scene cleanup includes blood spills following an assault, homicide or suicide, tear gas residue, vandalism removal/cleanup. There are many different sub-segments, named primarily after additional collateral, contingency, or preconditions, regarding the presence of non-blood borne organics, toxic irritants (e.g., tear gas) or disease vectors. However, it is the legality of charging a fee for mitigating potentially harmful biohazard situations that differentiates a registered crime or trauma practitioner from any general restoration, carpet cleaning, janitorial or housekeeping service.
