"Mae landlordiaid cymdeithasol wedi dweud wrthym ni nad yw'n ymddangos bod unrhyw un o'r rheini yn cynnwys y math o orchudd a oedd wedi'i ddefnyddio ar Dŵr Grenfell. Mae systemau chwistrellu wedi'u gosod mewn saith bloc yng Nghymru, ac wrth gwrs, fel rhan o'r newidiadau a gyflwynwyd fel rhan o Fesur Diogelwch Tân Domestig (Cymru) 2011, byddai'n rhaid i unrhyw flociau newydd neu unrhyw waith adnewyddu i flociau presennol gynnwys system chwistrellu. Cafodd y gofynion eu cyflwyno ar gyfer fflatiau a thai ar 1 Ionawr 2016.
“Social landlords have told us none of those appear to have been fitted with the type of cladding used in the Grenfell Tower.  Seven blocks in Wales have been retro-fitted with sprinklers – and of course where any new or converted blocks are developed here, under the changes introduced as part of the Domestic Fire Safety Measure (Wales) 2011, they would be required to include sprinklers. The requirements were introduced for flats and houses on 1 January 2016.
