Anti-scald bathroom equipment has been fitted in thousands of district homes after a campaign by Mary Creagh MP to prevent kids being burned.
Wakefield and District Housing (WDH) properties have been fitted with shower mixers that do not release water hot enough to cause burns.
All newly-built homes are required to have the thermostatic mixing valves (TMVs) after new regulations came into force three years ago.
And now the majority of WDH homes have the equipment after 30,000 of the mixers were fitted.
Ms Creagh launched a campaign to change the regulations in 2005, bringing together burns victims and medical experts to lobby the government.
WDH worked with in anti-scald bathroom manufacturer Inta, which has also campaigned on the issue.
Ms Creagh said: “Hot bath water is the major cause of severe scalding injuries among young children.
“I am delighted Wakefield District Housing and Inta have worked together to install these new valves which should drastically reduce scalding injuries.”
Stafford-based Inta’s Stuart Gizzi said: “This has to be seen as the start of a nationwide push to get more houses fitted with TMVs.
“We cannot emphasise enough how important it is to remember that temperatures any higher than 44°C can potentially be dangerous, or even deadly.”
Steve Rawson, WDH’s managing director of operations, said: “We are committed to protecting the safety of our tenants, and our work with Inta to install these TMVs will really help to keep people safe from the dangers of hot water.”
