Asbestos – Guide to Hazardous Air Pollutants used by the Irish Air Corps

Asbestos

CAS  1332-21-4

Hazard Summary

Asbestos production and use has decreased dramatically over the years in the United States. Exposure to asbestos may occur from ambient air, indoor air, or water. Effects on the lung are a major health concern from asbestos, as chronic (long-term) exposure to asbestos in humans via inhalation can result in a lung disease termed asbestosis. Asbestosis is characterized by shortness of breath and cough and may lead to severe impairment of respiratory function. Cancer is also a major concern associated with asbestos exposure, as inhalation exposure causes lung cancer and mesothelioma (a rare cancer of the thin membranes lining the abdominal cavity and surrounding internal organs), and possibly stomach, laryngeal, and colorectal cancer. EPA has classified asbestos as a Group A, known human carcinogen.

Please Note: The main sources of information for this fact sheet are EPA's Integrated Risk Information System (IRIS) (2), which contains information on the carcinogenic effects of asbestos including the unit cancer risk for inhalation exposure, and the Agency for Toxic Substances and Disease Registry's (ATSDR's) Toxicological Profile for Asbestos. (1)

Uses

  • Asbestos production and use in the U.S. has decreased dramatically over the years due to healthconcerns and regulations banning its use. (1)
  • U.S. production of asbestos decreased from 300 million pounds in 1973 to 6 million pounds in 2002. (3)
  • In 2010, there were two U.S. suppliers of asbestos and most of the asbestos used in the U.S. is imported from Canada. (3)
  • Asbestos has been used in building materials, paper products, asbestos-cement products, friction products, textiles, packings and gaskets, and asbestos-reinforced plastics. (1,4)
  • Many uses have been prohibited, including the spraying of asbestos-containing material on buildings and structures for fireproofing, insulation and decorative purposes, asbestos inclusion in patching compounds and asbestos heat shields in hair dryers. Asbestos substitutes continue to be developed. For example, nonasbestos friction materials are currently being used in disc brake pads, and substitutes have been developed for drum brake linings. (1)

Sources and Potential Exposure

  • Airborne exposure to asbestos may occur through the erosion of natural deposits in asbestos bearing rocks, from a variety of asbestos-related industries, or from clutches and brakes on cars and trucks. The concentrations in outdoor air are highly variable. (1,4)
  • Asbestos has been detected in indoor air, where it is released from a variety of building materials such as insulation and ceiling and floor tiles. It is only released, however, when these building materials are damaged or disintegrate. (1)
  • Asbestos may be released into water from a number of sources, including erosion of natural deposits, corrosion from asbestos-cement pipes, and disintegration of asbestos roofing materials with subsequent transport into sewers. (1,4)

Health Hazard Information

Acute Effects:

  • No studies were located on the acute (short-term) toxicity of asbestos in animals or humans. (1)

Chronic Effects (Noncancer):

  • Chronic inhalation exposure to asbestos in humans can lead to a lung disease called asbestosis, which consists of a diffuse fibrous scarring of the lungs. Symptoms of asbestosis include shortness of breath, difficulty in breathing, and coughing. Asbestosis is a progressive disease, i.e., the severity of symptoms tends to increase with time, even after the exposure has stopped. In severe cases, this disease can lead to death, due to impairment of respiratory function. (1,2)
  • Other effects from asbestos exposure via inhalation in humans include pulmonary hypertension and immunological effects. (1,2)
  • Feeding studies in animals exposed to high doses of asbestos have not detected any evidence of adverse toxic effects. (1,2)
  • EPA has not established a Reference Concentration (RfC) or a Reference Dose (RfD) for asbestos. (2)

Reproductive/Developmental Effects:

  • No studies were located on the developmental or reproductive effects of asbestos in animals or humans via inhalation. (1)
  • Birth defects were not noted in the offspring of animals exposed to asbestos in the diet during pregnancy. (1)
  • No effects on fertility were observed in animals exposed to asbestos in the diet during breeding, pregnancy, and lactation. (1)

Cancer Risk:

  • A large number of occupational studies have reported that exposure to asbestos via inhalationcauses lung cancer and mesothelioma (a rare cancer of the membranes lining the abdominal cavity and surrounding internal organs). (1,2,3)
  • Individuals who smoke and are also exposed to asbestos have a greater than additive increased risk of developing lung cancer. (1,2,3)
  •  Long and intermediate-range asbestos fibers (>5 micrometers (µm)) appear to be more carcinogenic than short fibers (<5 µm). (1)
  • Some occupational studies have reported an increased risk of stomach, laryngeal, or colorectal cancer from asbestos exposure. However, the data are not as strong as that for lung cancer and mesothelioma. (1)
  • Epidemiological studies have not found a clear association between asbestos exposure in drinking water and an increased risk of stomach cancer. (1,2,3)
  • A series of large-scale lifetime feeding studies in animals reported that exposure to intermediate-range asbestos fibers increased the incidence of a benign tumor of the large intestine in male rats, while short-range asbestos fibers showed no significant increase in tumor incidence. (1)
  • EPA has classified asbestos as Group A, human carcinogen. (2)
  • EPA uses mathematical models, based on human and animal studies, to estimate the probability of a person developing cancer from breathing air containing a specified concentration of a chemical. EPA calculated an inhalation unit risk estimate of 2.3 × 10-1 (fibers/cm3)-1. EPA eestimates that, if an individual were to continuously breathe air containing asbestos at an average of 0.000004 fibers/cm3 over his or her entire lifetime, that person would theoretically have no more than a one-in-a-million  increased chance of developing cancer as a direct result of breathing air containing this chemical. Similarly, EPA estimates that breathing air containing 0.00004 fibers/cm3 would result in not greater than a one-in-a-hundred thousand increased chance of developing cancer, and air containing 0.0004 fibers/cm3 would result in not greater than a one-in-ten-thousand increased chance of developing cancer. (2)

Physical Properties

  • Asbestos is the name applied to a group of six different fibrous silicate minerals that occur naturally in the environment. (1)
  • There are two groups of asbestos minerals: serpentine and amphibole. There are also nonfibrous forms of serpentine and amphibole which are not asbestos. (1)
  • Serpentine asbestos are relatively long and flexible crystalline fibers that may be woven, and includes the mineral chrysotile, and amphibole asbestos are more brittle than serpentine asbestos and includes the minerals amosite, crocidolite, tremolite, anthophyllite, and actinolite. (1)
  • Asbestos is neither volatile nor soluble; however, small fibers may occur in suspension in both air and water. (1)

Relavance to personnel who served in the Air Corps

  1. Pipework in a number of Air Corps buildings was lagged with Asbestos most notably the Apprentice hostel was lagged with badly damaged Asbestos until the early 1990s. So every apprentice who served from approximately the 55th Apprentice Class and before was exposed to asbestos in their sleeping environment.
  2. The apprentice hangar roof was made from asbestos.
  3. Parts of engine shop ceiling was discovered to be made from asbestos when it partially collapsed and dislocated the shoulder of a machinist working beneath it.
  4. The fire crew wore special fire suits made from asbestos. 

It is likely that we have missed many areas of asbestos usage  in both Baldonnel and Gormanston aerodromes so please help us by listing usage locations in comments section below.

Leo Varadkar urged to act on Air Corps chemical exposure ‘legacy’

Taoiseach Leo Varadkar has said he believes the courts should decide whether former Air Corps staff are suffering chronic illnesses due to chemical exposure.

Mr Varadkar made the comments yesterday in the Dáil where Sinn Féin Defence Spokesperson Aengus O’Snodaigh repeated calls for a health study of Air Corps members, similar to an analysis of Australian Air Force staff, which found technicians who worked with carcinogenic chemicals were at greater risk of illness.

Last year, the Irish Examiner revealed the State is facing a number of claims from former staff, and that whistleblowers had raised concerns about the safety of workers using chemicals at Casement Aerodrome, Baldonnel.

“While I have absolutely no doubt that the serious ill-health suffered by some former members of the Air Corps is real, it has not been proven whether this array of illnesses could be caused by chemical exposure,” Mr Varadkar said.

“There is litigation in the courts, which are the best place to assess the evidence and see whether the allegations are supported by that evidence,” he said.

Mr O’Snodaigh said a survey is needed as the implications of widespread staff exposure to the chemicals used goes beyond the seven cases currently against the State. “We do not want to be here in 10 years’ time with a higher death toll, having failed to address this scandal,”he said.

Brendan Howlin: Review Air Corps health claims

Labour leader Brendan Howlin is not satisfied with the Government’s response to the Air Corps chemical exposure scandal, and has called for an external review of the allegations.

In the absence of military or government statistics on untimely deaths in the Irish Air Corps we created our own. We are happy to have these tested or even proven wrong by better statistics gathered by the state in a comprehensive, open and transparent manner. #WeAreNotStatisticians

The State is facing seven High Court claims from former Air Corps technicians, who say they suffer chronic illnesses due to exposure to toxic chemicals while they were cleaning and servicing aircraft.

A number of whistleblowers have made protected disclosures about working conditions in Air Corps headquarters at Casement Aerodrome. The Health and Safety Authority subsequently investigated, and threatened legal action, unless the Defence Forces improved worker safety.

Mr Howlin raised the issue in the Dáil last month, and has since received correspondence from the Government.

“I’ve raised it with the Taoiseach directly and I’ve gotten a two-page response from the minister with responsibility for defence, and I’m not satisfied,” Mr Howlin said. “There needs to be at least an expert-review panel set up to look into this in some detail.”

However, Mr Howlin did not call for a full commission of investigation, but said that the findings of an external review should determine whether such a process is necessary.

“Whether a full tribunal of investigation is required remains to be seen, but the first step to that is to have an external, expert review, and that needs to happen immediately, and I certainly will be pressing for that,” he said.

This review should include a health study of Air Corps members past and present to determine if they have a higher prevalence of chronic conditions compared to the general public, he said.

“That would have to be a critical part of the review, because, once the fears are there, they have to be empirically checked out,” Mr Howlin said.

“They are either fact or not fact. There’s no point in people either dismissing them, or saying it’s a fact. We need to have external, independent, authoritative decisions on these matters.”

State faces seventh Irish Army Air Corps action

The State is facing a further High Court action from a former member of the Defence Forces allegedly suffering chronic ill-health due to exposure to chemicals in the Air Corps.

The disclosure of a seventh case came in the Dáil yesterday, where opposition politicians said the Government’s response to a growing health scandal over the past year was like ‘Groundhog Day’ in its repetition and inaction.

Last year, the Irish Examiner revealed six former Defence Forces members were suing the State over chronic health issues. A medical expert had advised that the health complaints were as a result of working conditions at Casement Aerodrome.

This newspaper also revealed how a number of whistleblowers had warned the Government that the Air Corps’ management of chemical exposure was inadequate, a claim vindicated after an inspection by the Health and Safety Authority.

Junior Defence Minister Paul Kehoe yesterday confirmed a seventh case. He denied claims there had been a cover-up within the Defence Forces to hide the extent of its knowledge of conditions in Baldonnell Aerodrome.

“The Minister of State seems, somehow, to be suggesting that his inaction is to serve the interests of those affected,” said Fianna Fáil defence spokeswoman Lisa Chambers.

“Minister, this particular issue is a little bit like Groundhog Day; we continue to ask questions, myself and others, and we continue to get the same stock response.

Sinn Féin defence spokesman Aengus Ó Snodaigh called for a health survey of Air Corps members to determine whether they are more at risk of serious illness.

“All the O’Toole report dealt with was whether the procedures were in place to deal with whistleblowers. This is not about the whistleblowers or the cases before the courts at the moment,” he said.

“The State is fighting them tooth and nail and I think it is on the losing side. If those are set aside, there are quite a number of other members who gave service to this State, through the Air Corps, who are suffering catastrophic health problems.

Dáil Éireann – Other Question 11 – 24th January 2018 – Irish Air Corps Whistle-blower

Lisa Chambers (Mayo, Fianna Fail)

Other Question No. 11

To ask the Taoiseach and Minister for Defence the further action he plans to take in relation to Air Corps whistle-blowers.

Air Corps scandal still some way from touching down

In a series of articles across 2017, the Irish Examiner revealed serious concerns about the working environment within the Air Corps — matters that have seen allegations of a deliberate cover-up, of victimisation of whistleblowers, and of a lackadaisical attitude towards health and safety that has put lives at risk, writes Joe Leogue.

While the stories broken by this newspaper since January have posed a myriad of questions for the State and the Defence Forces, the issues have one common controversy running throughout.

Have technicians within the Air Corps developed cancer, neurological problems, and other chronic conditions as a result of unnecessary exposure to toxic chemicals during their time at Casement Aerodrome?

Air Corps report ‘not available’ to reviewer

An official tasked with reviewing whistle-blower allegations of chemical exposure within the Air Corps was not given access to the Defence Forces’ own report on the claims, the Government has confirmed.

Six former Air Corps staff are suing the State, claiming their exposure to chemicals while in the Defence Forces caused cancers and other chronic illnesses they now suffer.

Meanwhile, three whistleblowers came forward to allege health and safety mismanagement within the Air Corps, in the years up to 2016. A subsequent inspection by the Health and Safety Authority confirmed many of the complaints outlined in the whistleblowers’ protected disclosures.

A Freedom of Information request earlier this year from Deputy Aengus O’Snodaigh had revealed Junior Defence Minister Paul Kehoe had been given a copy of a report entitled “Chemical Exposure Report (1994-2005)”.

The Department of Defence, meanwhile, tasked former civil servant Christopher O’Toole with reviewing claims from three whistleblowers who alleged the health of dozens of Air Corps staff may have been seriously compromised by exposure to chemicals used to clean and service aircraft.

In his report, however, Mr O’Toole concluded the terms of reference he was given had been ‘impractical’, and noted that appropriate records to demonstrate the Air Corps complied with health and safety regulations “are not readily available”.

This week, the Sinn Féin TD subsequently asked Mr Kehoe whether Mr O’Toole was provided with a copy of the “Chemical Exposure Report (1994-2005)”.

Mr Kehoe said it would not have been “appropriate” to give the report to Mr O’Toole. “As the report is subject to legal privilege, it was not appropriate to make it available to the independent reviewer,” the minister said.

Pressure for probe into Casement Aerodrome health and safety

The Government is under increasing pressure to set up a commission of investigation into alleged health and safety management failures at Casement Aerodrome.

Tánaiste Simon Coveney said the Government has received and will consider whistleblowers’ thoughts on the independent review into their allegations of health and safety mismanagement within the Defence Forces, and recommendations would be drawn up to go to Cabinet on the matter.

It comes after the Irish Examiner revealed how former Air Corps staff are suing the State and claim they now suffer chronic illnesses — including cancer — as a result of the Defence Forces’ failure to adequately manage their exposure to the hazardous chemicals they used to service and clean aircraft.

The Irish Examiner also first reported how three whistleblowers raised concerns about how health and safety was managed in the Air Corps and alleged that missing inspection reports on conditions at Casement Aerodrome were destroyed as part of a cover-up to hide what the Defence Forces knew about the working environment.

Taking leaders questions in the Dáil for the first time as Tánaiste, Mr Coveney said he is “personally familiar” with some of the cases Labour leader Brendan Howlin raised and with previous whistleblowers at Casement Aerodrome.
