The faster you can arrange clean-up of the scene, the less risk there will be of contamination from biohazards or further complications such as insect infestation. With traumatic situations such as these, particularly in the home, fast clean-up is also an important part of helping you to cope with the situation and start returning to normal. However, when dealing with a crime scene, we cannot start clean-up until the scene has been signed off by the police, which may cause some delay.
