It is widely thought that the cleaning of the area at a crime scene or traumatic incident is done by the Police. Unfortunately, that is not the case. In reality the cleanup is down to the family of the victim or the property owner.
At a time of enormous stress the last thing the family wants to do is deal with the cleaning and sanitisation of a room where there could be a large amount of body fluids. Especially if they are not trained in the safe removal and disposal of what is classed as Biohazardous Materials.
These body fluids are potential carriers of a large number of pathogens which are transferable to humans and include HIV and Hepatitis B.
This needs to be done by professional trained teams, wearing full personal protective equipment, who are used to dealing with these incidents.
