Dr. Tom Ryan:

I will take that question. We discussed that earlier. The issue was that the seals on one of the hatches of the filtration system were not appropriately installed which led to a breach of the hatch and a spill of lime into the facility. This was in 2017. Lime is used as part of the cleaning process. That was contained within the facility and we carried out an investigation. There were workers in the vicinity as well. The Health and Safety Authority investigated the matter from a health and safety perspective and we produced a report following the investigation, which is on our website.
