What is the first step in assessing a crime scene for restoration?

The correct step in assessing a crime scene for restoration is to conduct a thorough visual inspection to determine the extent of contamination and damage. This initial assessment is crucial because it allows the technician to identify all affected areas and the types of materials involved. By understanding the level of contamination and damage, the restoration process can be properly planned and prioritized.

A visual inspection helps to gather essential information about the scene, including potential hazards, the nature of the substances present, and areas that may require special attention or precautions. This foundational knowledge ensures that the subsequent actions taken, whether they involve cleaning, remediation, or further investigation, are based on a clear understanding of the scene's condition.

Taking photographs, while important for documentation, follows the visual inspection as it provides evidence of the pre-restoration state. Interviewing witnesses may provide context to the crime, but it does not directly aid in assessing the restoration needs. Immediate cleaning may be tempting, but without a proper assessment, actions could inadvertently spread contamination or overlook critical evidence.
