The third trait that is necessary is whether or not you can stomach the work. It may seem obvious but until you try you just don't know. It is one thing to watch a move or tv show, but can you actually handle the reality of dealing with the aftermath of a suicide, crime or undiscovered death? Being a crime and trauma cleaner means you will be touching, wiping, and smelling human bio matter. Blood, feces, urine, fat, and body tissue. You must be able to cope with the realities of the job.
