Cleaning a crime scene area is considered as cleaning dangerous materials.Thorough cleaning is necessary to consider the place as clean and free from any hazardous waste cleanup. However, cleaners with construction background are also helpful especially when dealing with meth cases where walls have to be taken down to clean the site thoroughly.
Once the body has been removed it is only proper that the site is properly cleaned and sanitised, but this is not the responsibility of a coroner. A professional biohazard specialist in crime scene cleanup shall take up the responsibility of cleaning the crime scene.
