  • Explain the physiological mechanisms of environmental asphyxia and entrapment-related deaths, including oxygen deprivation, restricted ventilation, and external compression.

  • Identify and document key scene indicators associated with environmental asphyxia incidents, including grain engulfment, soil collapse, confined-space events, and other entrapment scenarios.

  • Recognize common external examination and autopsy findings that may be present in environmental asphyxia and entrapment fatalities, while understanding their limitations and variability.

  • Integrate scene evidence, environmental conditions, witness statements, and postmortem findings to determine cause and manner of death and support accurate death certification.
