Under what circumstance can an accident site causing serious injury be disturbed?

The correct choice is based on the critical principle that the priority in any situation involving serious injury is to ensure the safety and well-being of individuals present. If an accident site is the scene of a serious injury, immediate action may need to be taken to preserve life or prevent further injury. This reflects an essential aspect of emergency management and health and safety protocols, prioritizing human life over the preservation of evidence or the integrity of the accident scene.

In Queensland mining law, while investigations and documentation are vital parts of the response to an accident, they generally take place after immediate health and safety concerns have been addressed. Disturbing the site to provide aid or to move an injured person out of harm's way is justified and necessary when lives are at risk. This understanding underscores the balance between legal obligations regarding evidence preservation and the moral imperative to protect individuals.

Other choices suggest conditions where the site can be disturbed that do not prioritize immediate safety. The investigation team readiness, inspector's permission, or documentation might result in delays that could compromise the health outcomes for injured individuals. Hence, the immediate response to preserve life or prevent further injury is the correct and most responsible course of action in these circumstances.
