Cause of death

Argon gas and plastic bag asphyxia

AI-generated summary

A 33-year-old man died by argon gas inhalation asphyxia using a plastic bag and cylinders purchased from a hardware retailer. He had long-standing depression and anxiety, experienced relationship breakdown and custody disputes with his ex-partner, and expressed suicidal ideation to his GP in March 2024 with a documented plan. Though he appeared improved in the weeks before death, the coroner found no clinical errors in his management. The case highlights systemic issues: argon gas remains readily accessible for purchase despite six previous coronal recommendations to restrict access through legislation. Unlike helium, which now has mandatory safety standards, argon regulation has been rejected twice by the Department of Health. No preventive opportunities were identified in the clinical care pathway.
