In 1995 the Irish Air Corps commissioned an independent third party organisation to carry out air quality testing in the Engine Repair Flight building. ERF comprised the Engine Overhaul facility, the Non Destructive Testing workshop and the Machine shop. Avionics Squadron was located in the same physical building as the ERF and the open attic spaces meant chemical vapours & fumes from either unit were free to flow in either direction.
The Avionics / ERF building was also less than 20m downwind from the 3m high Spray Paint Shop exhaust stack which exhausted benzene, hexamethylene diisocyanate, toluene and xylene.
Ambient Air Monitoring for Health & Safety at Work Report from the 2nd of August 1995 found that #Dichloromethane (also known as Methylene chloride) was found in some areas to be 175ppm. At the time The most stringent health and safety limits for #DCM were 50 ppm (TWA for 8 hours) and 126 ppm (STEL for 15 minutes).
Personnel, including other ranks employed in the Formation Safety Office, were never informed of these results. Avionics / ERF personnel were left in situ for a further 12 years before the workshops were finally condemned & demolished and needlessly exposed to #DCM and other chemicals.
Significantly Dichloromethane metabolises as Carbon Monoxide once inhaled but is lethal in many other different ways. We have at least 10 untimely deaths of men who worked in this building alone, their average age of death was 49.3 years and the youngest was only 32.
So we have one state body warning the general public about the dangers of Carbon Monoxide, while another state body hid evidence of a known carbon monoxide threat from personnel working in a heavily contaminated facility.
