Mae Llywodraethau'r DU wedi bod yn ymwybodol o rai o ffactorau risg RAAC ers y 1990au ac mae Llywodraeth Cymru wedi bod yn gweithio gyda Llywodraeth y DU a’r llywodraethau datganoledig eraill ers 2018 wrth reoli RAAC. Tan yn ddiweddar iawn, mae pob llywodraeth wedi ystyried bod y canllawiau ar gyfer rheoli RAAC mewn adeiladau yn ddull cadarn ar gyfer rheoli RAAC, ac o ran sicrhau bod diogelwch y rhai sy’n defnyddio’r adeiladau yn cael blaenoriaeth bob amser.
UK Governments have been aware of some of the vulnerabilities of RAAC since the 1990s and the Welsh Government has been working with the UK Government and other Devolved Governments since 2018 in the management of RAAC. Until very recently the guidance for the management of RAAC in buildings has been considered by all governments as being a robust approach towards managing RAAC and in ensuring building occupants safety is prioritised at all times.
