Cars damaged by factory dust emission
The incident at the Irish Cement Ltd factory in Mungret sparked a major health scare and local hospitals were put on alert.
The Health Service Executive said nobody presented at A&E departments as a result of the dust, but an investigation by the Environmental Protection Agency was under way last night after parts of Raheen and Dooradoyle were blanketed by gritty dust which spewed from the cement factory at around 10.30pm.
