Judy Ingham, aged 89, suffered severe burns from excessively hot water while bathing in her apartment on 26 August 2022, dying 26 days later from burn wound complications. A licensed plumber failed to install a required temperature control device (TCD) when replacing her hot water system on 19 April 2022. Regulations mandate hot water delivery at bathtubs not exceed 50°C; without a TCD, her system delivered water at 70°C. The coroner found systemic failures in plumber compliance, lack of mandatory professional development requirements, and absence of data collection on hot water system installations. Key lessons: ensure temperature control devices are installed on all hot water system replacements; implement mandatory continuing professional development for licensed plumbers; establish certificate of compliance systems; improve regulatory oversight and notification procedures for incidents.
