An inquest jury has blamed government failures after the death of a baby who was scalded when a water tank burst above her cot.
Rhianna Hardy, aged 10 months, received 95% burns in the accident at her home in Taunton, Somerset, in November 2006.
Faults in the type of water tank which exploded, killing Rhianna, were not passed on by the authorities following a previous incident, the inquest heard.
Sharon Minster, 30, was killed when a tank burst in Penwith six years ago.
Coroner Michael Rose, sitting in Taunton, said: "The scalding was a result of a thermostat failure.
"The tragedy would not have occurred if the full implications of a similar incident at Penwith in 2002 had been drawn to the attention of landlords by the relevant authority and steps taken to insure that the water systems complied with current British standards."
The tank above Rhianna's bed burst after the thermostat broke, leaving the water to boil continuously and venting it into a cold water storage tank.
That tank, which was made of plastic, melted and exploded over Rhianna's cot.
