Worker claims he was exposed to toxic chemicals while working on refurbishment at Intel plant

A man who has claimed he was exposed to a toxic and noxious chemical while working on a refurbishment job at the Intel Ireland plant has launched a High Court action.

Seven years after the alleged exposure the prognosis for 71-year-old John Matthews w,ho suffers from shortness of breath, is chronic, his counsel Barney Quirke SC told the court.

The claims relate to the refurbishment of a clean room where microchips are manufactured at the Leixlip, Co Kildare, plant and the pouring of a chemical sealant known as Penatron ASTC 3003c

The case is being regarded as a test case for as many as 10 other actions being taken in the High Court in relation to alleged exposure.

Opening the case, Mr Quirke SC, with Richard Lyons SC, said the alleged exposure has had a cruel effect on the life of father-of-four John Matthews and his retirement is completely altered from what he expected.

His client worked as a carpenter and was involved in what were called pop outs where the chemical Penatron was poured.

Mr Matthews, of Ardee Road, Dundalk, Co Louth, has sued his employer Ardmac Ltd with a registered office at Swords Business Campus, Balheary Road, Swords, Co Dublin, and Intel Ireland Ltd with registered offices at Simmonscourt House, Simmonscourt Road, Ballsbridge, Dublin. The refurbishments works on an Intel clean room were being carried out by Ardmac at the Leixlip plant.

Mr Matthews has claimed between June 2013 and October 2014 he was allegedly exposed to toxic and noxious chemicals including Penatron/ASTC 3003c while he was working at the plant.

He has also claimed a number of his co-employees were allegedly exposed to known carcinogens.

A considerable number of Irish Air Corps have gone on to work in Intel and have generally been astounded by the high levels of chemical health & safety employed there.

While it is very disappointing to hear of personnel being injured at Intel it just goes to show that even with a high quality health & safety regime dangerous exposures can still happen. 

The Irish Air Corps on the other hand had dangerous chemicals dripping down the walls from extractor fans yet still claim that Air Corps personnel were not exposed to dangerous chemicals. Safety was so poor in the Irish Air Corps that personnel didn’t even know what PPE was, it wasn’t part of the lexicon. 

Below is the safety data sheet for the sealant alleged to have caused harm in Intel. The dangerous chemical components of this sealant are called isocyanates. Isocyanates are notorious immune sensitisers and were the class of chemicals involved in the Bhopal disaster. Persons sensitised to isocyanates can suffer asthma attacks & anaphylaxis at levels as low as one part per billion. Furthermore sensitisation to one isocyanate like HDI can lead to a cross sensitisation to other isocyanates like MDI or TDI etc. 

The Spray Paint Shop at Casement Aerodrome emitted hexamethylene diisocyanate on a daily basis as a component of polyurethane paint, these emissions contaminated Engineering Wing Hangar while other personnel went about their unrelated daily business.

BFTS personnel were also exposed to methyl-diphenyl diisocyanate when they filled barrels with expanding foam for air firing at Gormanston.

If anyone who has lost a loved one before age 66, who had worked in the Irish Air Corps as military or civilian personnel or as work experience students please feel free to contact the Irish Independent journalist Rodney Edwards via email to 

If you are serving or former personnel and if you are sick because of your service or if were or are being bullied for being sick please consider emailing Rodney too.
