Fodd bynnag, mae bob amser le i wneud mwy. Mae gormod o ddigwyddiadau difrifol o hyd – tân sy’n achosi i aelodau o’r cyhoedd gael eu lladd neu eu hanafu’n ddifrifol, a/neu sy’n peri risg difrifol a heb ei reoli i ddiogelwch diffoddwyr tân. Mae lleihau nifer a difrifoldeb digwyddiadau o’r fath yn dibynnu ar ddeall beth sy’n eu hachosi a sut y gellid eu hatal.
However, there is always scope to do more.  There are still too many serious incidents –fires which cause death or serious injury to members of the public, and/or expose a serious and unmanaged risk to firefighter safety.  Reducing the incidence and severity of such incidents relies on understanding their causes and how those might be prevented.
