Dozen children hospitalized after toxic fumes at Dublin swimming pool

Twelve children attending swimming lessons at a Dublin facility required hospital treatment after exposure to hazardous chemical fumes on Thursday. One adult also needed medical attention following the incident at the Clayton Hotel Liffey Valley. According to BBC News, the contamination occurred in the pool area during an active lesson session.

Irish national broadcaster RTÉ reported that several of the young people exhibited symptoms of

respiratory distress and irritation

. The Dublin Fire Brigade (DFB) responded swiftly to contain and resolve the hazard, deploying resources from multiple stations across the city.

What caused the chemical incident?

The Dublin Fire Brigade's chief fire officer Greg O'Dwyer identified the root cause as

overmixing

of chlorine and another chemical within the pool's plant room. This accidental combination of pool maintenance chemicals created the toxic fumes that affected those in the facility. The incident underscores the importance of proper chemical handling protocols in aquatic facilities.

How did emergency services respond?

Firefighters equipped with specialized protective gear entered the contaminated area to manage the situation. O'Dwyer explained that personnel wearing

gas-tight suits

entered the scene and

isolated the chemical

to prevent further exposure. The rapid response prevented the situation from escalating and protected the wider community.

The Dublin Fire Brigade dispatched units from fire stations across the city, including Tallaght, Dolphins Barn, Donnybrook and Dun Laoghaire. Specialist HazMat appliances from Donnybrook and Dun Laoghaire fire stations attended the scene and

set up a decontamination zone

to safely manage those affected and prevent contamination spread.

What was the scope of the incident?

At the time of the chemical release, 24 children were in the pool participating in organized swimming lessons, along with supervising adults and parents. The presence of multiple people in the facility meant that exposure risk was significant, making the swift emergency response critical to preventing serious injuries. The DFB confirmed in a statement that

there was no danger to the wider public

following containment of the chemical.

The Clayton Hotel Liffey Valley declined to provide comment when contacted by media outlets regarding the incident or any subsequent safety measures being implemented.
