After an accident, what can be done with the site before documenting it?

The idea that nothing can be done at the accident site before documenting it is based on the critical importance of preserving evidence. This is essential for any subsequent investigation or legal proceedings. Allowing the site to remain untouched ensures that all details remain intact and can be accurately documented for liability assessment, insurance claims, and other legal considerations.

However, it's also important to understand protocols involved in accident scenarios. There are typically some allowable actions that can be taken to manage the site effectively without compromising evidence. For instance, securing the area with barriers to prevent unauthorized access or conducting a preliminary assessment to ascertain safety risks can be essential steps taken in many situations without altering the evidence significantly.

Thus, while the notion of doing nothing might be the most cautious approach from a legal perspective regarding evidence preservation, it doesn't reflect the entirety of what safety protocols or management strategies can be employed in practice in response to an accident.
