Concern over multiple carbon monoxide alarms being triggered in Mayo estate

Multiple carbon monoxide alarms have been triggered in a Mayo housing estate - prompting emergency responses, including gardai, gas services, the fire brigade’s attendance and drainage of the sewer system.

While residents were grateful for the swift emergency response to the situation yesterday, they are 'deeply concerned' about the situation.

The issue at Lios na Circe, Saleen, has coincided with a persistent obnoxious odour in the area, which is often noticeable during humid weather, particularly following dry spells.

This problem has been ongoing for several years and the odour still persists even after yesterday's sewer drainage, suggesting a continuing environmental or infrastructure issue.

A spokesperson stated: "Our proximity to a river known to produce strong odours may indicate that decomposing organic matter as well as sewer gas emissions are contributing to the build-up of hazardous gases, including carbon monoxide.

"We would like to highlight that carbon monoxide is a highly dangerous gas, which is colourless, odourless, and potentially lethal.

"Even at moderate exposure levels, it can cause serious health issues, while prolonged or high-level exposure can lead to unconsciousness, long-term neurological damage, or death.

"The fact that multiple alarms were triggered across several homes raises serious concerns about public health and safety.

"We respectfully request an urgent investigation into the following issues.

"The potential presence of sewer gas (including CO, methane, and hydrogen sulphide) in the area.

"The condition and ventilation of the estate’s sewer infrastructure.

"Possible environmental contamination or improper waste disposal in the adjacent field and river.

"Monitoring of ambient carbon monoxide levels around the estate.

"Measures to ensure resident safety, including recommendations for long-term prevention.

"This is a serious health and safety concern, and we believe it requires coordinated attention from environmental, health, and infrastructure departments."

The matter has been brought to the attention of a number of elected representatives in the town.

When contacted, Councillor Michael Kilcoyne said he strongly supports the residents in seeking an investigation into the matter.

"This is an issue that needs to be urgently addressed," he added.
