Am nifer o flynyddoedd, mae'r baich hwnnw wedi disgyn ar ysgwyddau ein gwasanaethau tân ac achub.  Mae ganddynt y sgiliau, y gallu a'r cyfarpar i ddelio â llifogydd mawr, ac i achub pobl o ferddyfroedd.  Ond er eu bod nhw bob amser yn ymateb hyd eithaf eu gallu, maent yn gwneud hyn ar sail wirfoddol.  Nid yw'n ofynnol iddynt wneud hyn, ac nid oes eglurder ar gyfer diffoddwyr tân, ymatebwyr eraill nac aelodau o'r cyhoedd.  Yn wir, fel y mae pethau ar hyn o bryd, byddai'n bosibl iddynt stopio gwneud y gwaith hwn yn gyfan gwbl – ac mae rhai Awdurdodau Tân ac Achub wedi ystyried gwneud hyn eisoes.
For many years, that burden has fallen on our fire and rescue services. They have the skills, capabilities and equipment to deal with major floods, and to rescue people from standing bodies of water. But while they always respond to the best of their ability, they do so voluntarily. There is no requirement on them to do so, and no clarity for firefighters, other responders or members of the public. Indeed, as things stand it would be perfectly possible for them to stop this work altogether – and some Fire and Rescue Authorities (FRAs) have actively contemplated doing so.
