Who will be the champion ? ARF, Avionics, BFTS, ERF or MTS?

All the below illnesses are known* to be caused by dichloromethane (DCM) also known as methylene chloride.

DCM was banned after a vote in the European Parliament in January 2009. The ban came into place in 2011 but the Irish Air Corps were still happy to let unsuspecting personnel use DCM without PPE or training in 2015 & likely beyond.

The Irish Air Corps finally issued PPE to all personnel using chemicals in 2017 a full 20 years after being told to do so by state body Forbairt.

Particulate matter from aircraft engines affects airways

According to the World Health Organization (WHO), seven million people worldwide die as a consequence of air pollution every year. For around 20 years, studies have shown that air-borne particulate matter negatively affects human health. Now, in addition to already investigated particle sources like emissions from heating systems, industry and road traffic, aircraft turbine engine particle emissions have also become more important.

In a unique, innovative experiment, researchers have investigated the effect of exhaust particles from aircraft turbine engines on human lung cells.

The cells reacted most strongly to particles emitted during ground idling.

It was also shown that the cytotoxic effect is only to some extent comparable to that of particles from gasoline and diesel engines.The primary solid particles, i.e. those emitted directly from the source, have the strongest effect on people in its immediate vicinity. 

Now a multidisciplinary team, led by lung researcher Marianne Geiser of the Institute of Anatomy at the University of Bern, together with colleagues from Empa Dübendorf and the University of Applied Sciences and Arts Northwestern Switzerland (FHNW), has shown that primary soot particles from kerosene combustion in aircraft turbine engines also cause direct damage to lung cells and can trigger an inflammatory reaction if the solid particles are inhaled in the direct vicinity of the engine.

The researchers demonstrated for the first time that the damaging effects also depend on the operating conditions of the turbine engine, the composition of the fuel, and the structure of the generated particles.

Extremely small particles in the nanoscale range

Particles emitted from aircraft turbine engines are generally ultrafine, i.e. smaller than 100 nm. By way of comparison, a human hair has a diameter of about 80,000 nm. When inhaled, these nanoparticles — like those from other combustion sources -efficiently deposit in the airways. In healthy people, the well-developed defense mechanisms in the lungs normally take care of rendering the deposited particles ineffective and removing them from the lungs as quickly as possible.

However, if the inhaled particles manage to overcome these defense mechanisms, due to their structure or physico-chemical properties, there is a danger for irreparable damage to the lung tissue. This process, already known to researchers from earlier experiments with particle emissions from gasoline and diesel engines, has now also been observed for particle emissions from aircraft engines.

Toxicity depends on the operating conditions of the turbines and the type of fuel

Evidence of increased cell membrane damage and oxidative stress in the cell cultures was identified. Oxidative stress accelerates ageing of cells and can be a trigger for cancer or immune system diseases.

Overall, according to the researchers, it has been demonstrated that the cell-damaging effect caused by exposure to particles generated by the combustion of gasoline, diesel and kerosene fuel are comparable for similar doses and exposure times.

Additionally, a similar pattern was found in the secretion of inflammatory cytokines after exposure to gasoline and kerosene fuel particles.

Aerosols: distance from the source is crucial

Aerosols are the finest solid or fluid substance suspended in the air. In combustion processes, the composition of ultrafine particles is highly variable. In addition, aerosols are unstable, and they are modified after their formation. Primary ultrafine solid particles have a high diffusion velocity. As a result, at high concentrations such particles either stick together or attach to other particles. Therefore, the effect of primary ultrafine particles depends on the distance from the source, implying that there is a difference depending on whether a person is close to the source (such as people at the roadside ) or at a greater distance (aircraft taxiing or taking off). Further research is needed to clarify how strong the impact would be at a greater distance from an aircraft engine

The layout of the Irish Air Corps base at Casement Aerodrome ensures that aircraft exhaust gasses are blown over populated sections of the airbase when winds are from the south, south east or south west. This includes hangars, offices, workshops and living in accommodation such as the apprentice hostel and married quarters. Calm weather also creates conditions where exhaust gasses linger in higher concentrations.

This results in all Irish Air Corps personnel (commissioned, enlisted, civilian & family) being exposed to emissions from idling aircraft engines, emissions that are known to cause harm.

In the mid 1990s a study of air pollution adjacent to the ramp area at Baldonnel was commissioned. This report relating to this study has gone missing. 

  • Anecdotal evidence suggests increased prevalence of occupational asthma & adult onset asthma amongst serving & former personnel who served in Baldonnel or Gormanston aerodromes. 
  • Older gas turbine engines produce dirtier exhaust gasses.
  • Idling gas turbine engines produce dirtier exhaust gasses.
Below are some of the gas turbine powered Air Corps aircraft that were powered by elderly engine designs.

RAAF jet fuel damaged ground crews’ body cells; long-term consequences unknown, says groundbreaking research

Royal Australian Air Force (RAAF) personnel who worked with widely used jet fuel suffered damage to their body’s cells with unknown long-term consequences, according to groundbreaking research released after a Freedom of Information laws request.

Defence’s senior physician in occupational and environmental medicine, Dr Ian Gardner, described the findings as a “part of the puzzle” and a hypothesis-making study”, and pointed it out that it was one of a series of pieces of research currently underway.

“What it shows is there is evidence of small but persistent cellular damage,” Dr Gardner told the ABC. He said it was not yet clear what the long-term effects of that damage might be.

“For the future though there are a lot of other aircraft maintenance workers who have done similar jobs on other aircraft types, and now Defence and DVA and Air Force are considering what additional work should be done in relation to those other people who are not actually on the F-111 programs but have done essentially similar work,” Dr Gardner said.

The Jet Fuel Syndrome Study also shows that the fuel is more toxic to the body’s cells than the two solvents initially blamed for the sickness suffered by the deseal/reseal workers, and that the toxicity is even higher when those solvents and the fuel were mixed.

The results of the research project, headed by Professor Francis Bowling of Brisbane’s Mater Hospital, were handed to Defence last September, and have been the subject of significant scrutiny and review due to the potential significance of the findings.

They will give heart to former and serving Defence personnel who believe they have been left out in the cold by Defence after developing serious health complaints while working with fuel and other substances.

Junior Minister with responsibility for Defence said in the Dáil that he was assured by the Irish Air Corps that the RAAF F1-11 deseal/reseal exposure tragedy is completely different to any exposures at the Irish Air Corps.

Was the minister suggesting that Irish Air Corps gas turbine engines don’t run on jet fuel?


Army Deafness Claims & the role of Independent Newspapers Group

In the early 1990s the Irish Independent & Evening Herald kicked off a campaign of ridicule against the Irish Defence Forces due to the high age profile of Irish military personnel.

In the 1990s Irish Defence Forces personnel were issued with ONE pair of disposable ear plugs annually and were fined if they lost them.

Driven by “The Troubles” in Northern Ireland, the ranks of the Defence Forces had swelled in the 1970s and with a severe recession in the 1980s personnel were obviously reluctant to leave.  Subsequently the average age of an Irish soldier in the early 1990s hovered around the 42 year age mark.

Being true patriots, the Irish Independent & Evening Herald kicked off a campaign of ridicule against the Defence Forces trotting out “Dad’s Army” headlines and urging the government to reduce the age profile.

Knowing how Independent newspapers group operate they were probably conniving with some political party to bring this about. Perhaps it was Fine Gael who connived with the Indo although later the same newspaper helped topple the FG led rainbow coalition with the infamous “it’s payback time” headline the morning of a general election.

Ray Burke TD had issued an Independent Newspapers group subsidiary “Princes Holdings” with MMDS licences for the rebroadcasting of TV signals across Ireland and the Indo had subsequently gotten a bit upset that the rainbow government had failed to crackdown on community TV deflectors which ate into their MMDS profits.  As it turns out Princes Holdings had issued cheques of £30,000 made payable to “cash” to Ray Burke before he awarded them the licences.

In order to lower the age profile, the Department of Defence had to find a way of encouraging older soldiers to leave so that they could start a recruitment campaign for younger personnel. If any other state or semi state employer at the time needed to reduce headcount they offered a Voluntary Early Retirement (VER) package to entice older personnel to leave but the Department of Defence had a better idea.

Military personnel were in a somewhat insecure position in terms of employment in that they were on rolling contracts some of which were in terms as low as 3-years. It was possible that the Defence Forces could decide that your “service was no longer required” and at the end of a particular contract term you could be refused re-engagement. The Department of Defence decided take advantage of “service no longer required”.

The Department of Defence decided to introduce a stringent annual medical and a stringent annual fitness test. As part of the annual medical they introduced a hearing test and this is where the spectacular own goal kicked into play.

Personnel who had served the Defence Forces during a very difficult period in the history of the Irish state started to be informed that their service would be no longer required because their hearing was not up to the required new standard.

Anyone who served in the Defence Forces during this period knows that Health & Safety was nonexistent. There are stories of soldiers bringing civvy ear defenders to range practice only to be told to take them off because the were not “issued”.  All personnel, including those firing heavy weapons , such as artillery, mortars & naval guns, had to make do with stuffing cotton wool into their ears if they were lucky.

When some basic disposable foam earplugs were eventually introduced there were occasions where these were handed out on the ranges only to be collected again and handed out again “used” to different personnel the next day. Yes, some personnel received disposable earplugs that had been inside someone elses ear.

The Defence Forces commenced informing personnel that their service would no longer be required and indeed some were discharged on medical grounds for hearing loss. This spread panic amongst serving personnel as they faced losing their livelihood in a country still in tough economic circumstances.

When personnel started to compare the printed results of their audiometry tests they started to notice a consistent common pattern in the hearing loss. The loss was most pronounced at the frequency range that matched gunfire.

Considerable rules & military law existed for the protection of hearing in the Defence Forces stretching as far back as the the Defence Act of 1954 but these had been utterly ignored. Similar to how the Irish Air Corps ignored legislation relating to chemical Health & Safety, the Defence Forces and the Department of Defence simply ignored their own rules on protecting serving soldiers hearing to save money.

Internal DoD/DF communications came to light where it was revealed that spending of £2 million on full hearing protection for all personnel was refused on cost grounds.

The threat of job losses spurred personnel to take legal action for the hearing loss they suffered. This later spread to FCA/RDF personnel as they were treated in an equally appalling manner.

Eventually the Department of Defence did introduce a Voluntary Early Retirements scheme which ironically was used to bully Irish Air Corps personnel out of SAR squadron at Baldonnel. A SAR winchman who had been injured likely by exposure to aviation fuel & exhaust gasses was treated as a malingerer and returned from sick leave to find an already completed VER form in his locker…all that was left was to sign the dotted line.

Even today the Department of Defence still try to paint the biggest own goal in the history of the state as a scam perpetrated by soldiers and the Independent who helped kick off the whole scandal are happy to keep spreading this misinformation.

Perhaps the Indo can investigate how thousands of serving, retired & reserve personnel were able to spoof deafness at 4kHz?  Anyone who has ever sat an audiometry evaluation knows that the frequencies are fed to you randomly so either thousands of personnel are pitch perfect at spotting 4kHz signals or perhaps it wasn’t a scam at all and through decades of neglect the hearing of thousands of personnel was damaged.

We know who the courts believed!

Incidentally with 78 untimely deaths in the Irish Air Corps workplace chemical exposure,  the Irish Independent are more than willing to look the other way and completely ignore the tragedy. No shareholders interests are being harmed obviously and you only have to consider their anti Sinn Fein headlines to understand how politically directed the Indo currently are.

Delay – Deny – Die

It is interesting to note that the Independent have trotted out former Minister for Defence Michael Smith and there are two things worthy of note.
Firstly Minister Smith,  who paints himself as a hero who defended state coffers from greedy, cheating Defence Forces personnel, was a member of the Fianna Fail cabinet who struck a deal in 2002 to indemnify religious orders from legal action due to clerical child abuse. It has estimated that this deal which Smith’s cabinet signed off, has cost the state in the region of €1,500,000,000, yes folks Smith was party to actions that left the irish state liable for claims totalling €1.5 billion so far. 
Secondly, a serving member of the Irish Air Corps was knocked down and left for dead in a hit & run collision outside Templemore in October 1994 This man was badly injured suffering fractured eye sockets, haemorrhaged eyes, thirty fractures to his upper & lower jaws, his back was broken in four places, his hips were dislocated and his internal organs bruised.
This motorist drove over his head, did a U turn, stopped to look at him and then drove off leaving him to eventually fall into a coma.
The injured Air Corps technician, who had represented the Defence Forces as an athlete at national level, worked hard to make a good recovery . He subsequently attempted to carry out a fitness test required to extend his contract but the Air Corps refused to allow him take the fitness test saying he wasn’t medically fit to conduct the test.
The Air Corps technician sought the assistance of Minister Smith to intervene and overturn the decision to not allow him to conduct his fitness test but the minister never intervened and the airman was effectively sacked.
The motorist was charged with leaving the scene of an accident/crime by Gardai. The victim’s legal team called the Gardai seeking to know when the case was coming to court, as their client was obviously the chief witness, but the Gardai informed the victims legal team that no date was scheduled. 

It turns out that the information the Gardai passed to the victim’s legal team was untrue and the case went to court a few days subsequent to the phone call without the victim being present. With no witnesses the charges against the motorist were dismissed.

By sheer coincidence the woman who knocked down the Air Corps technician and left him for dead happened to be a niece of Minister Michael Smith, the same minister who would not help him save his job.
