Ten children and one adult are taken to hospital after an “excess chlorine incident” at a swimming pool at the Clayton Hotel in Liffey Valley, west Dublin. Multiple outlets report that 23 people are medically assessed following the incident.

Irish media cite confirmation from the Dalata hotel group and describe the problem as a chlorine-related chemical exposure at the hotel pool. Reports differ slightly on the hospitalisation numbers: one outlet says 11 people are hospitalised overall, while another specifies 10 children and one adult. RTE reports that 12 children are taken to hospital, indicating variation in how figures are counted or updated during the response. All accounts agree the event prompts medical attention for children at the hotel.

Authorities and the hotel respond after the incident, with figures indicating a mixture of hospital treatment and medical assessments. The reports frame the cause as excessive chlorine rather than another type of chemical leak, but do not provide further details on root cause in the accounts provided.
