Y llynedd, fe wnaethom ganfod tuedd sy'n achosi pryder o ran tanau domestig dosbarthu trydanol - er enghraifft y rheini sy'n dechrau mewn ceblau, socedi, mesuryddion a blychau ffiwsiau. Yn wahanol i ffynonellau hysbys eraill o danau mewn anheddau, mae'r rhain ar gynnydd cyson. Mae Ysgrifennydd y Cabinet wedi ymrwymo i ymchwilio i'r cynnydd hwn ac maen cyhoeddi'r canfyddiadau heddiw.
Last year we detected a concerning trend in domestic electrical distribution fires – for example those starting in cabling, sockets, meters and fuse boxes. Unlike other known sources of dwelling fires, these are showing a sustained increase. The Cabinet Secretary committed to undertaking research into this increase and is publishing the findings today.
