Ireland : Poolbeg incinerator incident is a major mishap


Hospitalisation of 11 workers adds to the pressure on the Dublin plant

The hospitalisation of 11 workers following a major incident at Dublin’s new waste incinerator at Poolbeg forced the temporary closure of the plant within days of it coming into operation.

The incinerator is still only at the commissioning stage, but the timing of the incident undermines attempts to reassure local people about the safety of the plant.

According to Dublin Waste to Energy Ltd, “a small amount of lime” was inadvertently released late on Wednesday night inside the incinerator’s flue-gas treatment area during the commissioning and testing of the facility.

This was immediately converted into “a cloud” that rose through that section, where 30 construction workers were taking down scaffolding.

Eleven of the workers subsequently felt unwell and attended St Vincent’s University Hospital.

Nine were released on Thursday, but two were detained overnight. One of the two was reported to have respiratory problems but was getting better, while the other had sore eyes.

The company said it appeared from a preliminary examination that the release was due to a problem with a door seal at the bottom of a silo, through which 1 to 2 cubic metres of lime was discharged.

John Daly, managing director at Covanta Energy Ireland, indicated that what happened would be fully investigated, though he did not believe it was caused by human error.

The Health and Safety Authority (HSA) nonetheless has classified the incident as an “uncontrolled release” and a “dangerous occurrence”.

The HSA is conducting an investigation into what happened.

The Environmental Protection Agency (EPA) visited the plant and said that the “lime release was contained in the building and there was no loss of lime to the environment”. It is satisfied there was no danger to the public .

Hydrated lime removes harmful chemicals from incinerator emissions before they reach the atmosphere, preventing pollution.

The HSA says it was notified at 6am on Thursday of the incident, while it is understood that the EPA inspection of the plant only commenced mid-afternoon on the same day.

Covanta Energy Ireland has said the safety of its employees and contractors “is of utmost importance to Covanta”.
