Helicopter crews suing MOD, claiming exhaust fumes caused their cancer

The personnel claim toxic fumes emitted from the aircraft caused their illness, and they are accusing the MOD of being negligent about the risk to their health.

The Sea King is one of the helicopter types whose exhaust fumes allegedly caused cancer among a number of former aircrew

The Ministry of Defence is being sued by crew members who have been diagnosed with cancer after serving on military helicopters.

The personnel claim toxic fumes emitted from the aircraft caused their illness, and they are accusing the MOD of being negligent about the risk to their health.

According to a report by The Times, crew members who served on board helicopters such as the Sea King, Wessex, Puma and Chinook are among those who are taking legal action.

It includes those who’ve served in the Royal Navy, Army and Royal Air Force from a variety of ranks.

They are saying they were exposed to concentrated levels of toxic exhaust fumes during their flights.

The say they have subsequently been diagnosed with illnesses such as non-Hodgkin’s lymphoma, multiple myeloma, lung cancer, throat cancer and testicular cancer.

At least three of the former personnel affected have already passed away, while others have been diagnosed with terminal cancer.

Five former service personnel have received out-of-court settlements, including a former flight sergeant who trained Prince William in the RAF.

It is being claimed the Government knew about the risk posed by the Sea King’s exhaust as far back as 1999, but aircrew continued to fly on board without safety precautions.

A Ministry of Defence spokesperson said: “We hugely value our service personnel and veterans and owe a debt of gratitude to all those who serve, often with great personal sacrifice.

“We continually review our policies to ensure they are aligned with good practice and protect our people from harm.

Service personnel and veterans who believe they have suffered ill health due to service from 6 April 2005 have the existing and long-standing right to apply for no-fault compensation under the Armed Forces Compensation Scheme.”

Is anything safe at Air Corps base?

Damaged drains, cables across hangar floors, a leaking oven, oil spills and a risk of Legionnaires’ disease… these are just a few of the workplace hazards inspectors found at Casement Aerodrome

Health and safety inspections on the Irish Air Corps discovered spills of hazardous brake fluid, a water supply that carried the risk of Legionnaires disease, fall risks, damaged drains and trailing cables across hangar floors.

The Defence Forces were also issued with a contravention notice by the Health & Safety Authority (HSA) over the use of some chemicals without proper training of personnel.

A separate report from December said that several safety data sheets were outdated and recommended additional training on the handling of specific restricted chemicals.

Human Health Effects of Trichloroethylene: Key Findings and Scientific Issues

Abstract

Background

Background: In support of the Integrated Risk Information System (IRIS), the U.S. Environmental Protection Agency (EPA) completed a toxicological review of trichloroethylene (TCE) in September 2011, which was the result of an effort spanning > 20 years.

Objective

We summarized the key findings and scientific issues regarding the human health effects of TCE in the U.S. EPA’s toxicological review.

Methods

In this assessment we synthesized and characterized thousands of epidemiologic, experimental animal, and mechanistic studies, and addressed several key scientific issues through modelling of TCE toxicokinetics, meta-analyses of epidemiologic studies, and analyses of mechanistic data.

Discussion

Toxicokinetic modelling aided in characterizing the toxicological role of the complex metabolism and multiple metabolites of TCE. Meta-analyses of the epidemiologic data strongly supported the conclusions that TCE causes kidney cancer in humans and that TCE may also cause liver cancer and non-Hodgkin lymphoma. Mechanistic analyses support a key role for mutagenicity in TCE-induced kidney carcinogenicity.

Recent evidence from studies in both humans and experimental animals point to the involvement of TCE exposure in autoimmune disease and hypersensitivity.

Recent avian and in vitro mechanistic studies provided biological plausibility that TCE plays a role in developmental cardiac toxicity, the subject of substantial debate due to mixed results from epidemiologic and rodent studies.

Conclusion

TCE is carcinogenic to humans by all routes of exposure and poses a potential human health hazard for noncancer toxicity to the central nervous system, kidney, liver, immune system, male reproductive system, and the developing embryo/fetus.

Protection of Defence personnel against health risks of chromium-6 was inadequate

Background

From 1984-2006, employees of the Dutch Ministry of Defence were exposed to chromium-6 during maintenance work. This occurred at five so-called POMS sites (POMS: Prepositioned Organizational Materiel Storage), where principally American NATO equipment was stored and maintained by Defence personnel.

The Ministry of Defence had the responsibility to inform both employees and occupational physicians about the health risks of exposure to chromium-6-based paint and to ensure the use of the appropriate protective equipment. This did not happen adequately.

Exposure

Netherlands Armed ForcesThe extent to which Defence personnel were exposed to chromium-6 at the five POMS sites differed according to their positions. Employees in the technical maintenance positions had the highest exposure to chromium-6. The chromium-6 to which Ministry of Defence personnel were exposed in the period 1984-2006 can no longer be detected in their bodies. The fact is that chromium-6 is readily converted to chromium-3 in the body and is subsequently excreted.

Health effects of chromium-6

Defence personnel working in technical maintenance positions were exposed to chromium-6, which may have caused the following diseases: lung cancer, nasal and nasal cavity cancer, gastric cancer, chromium-6-related allergic contact dermatitis, allergic asthma and allergic rhinitis, chronic lung diseases and perforation of the nasal septum due to chromium ulcers. Because most of these diseases can also be induced by other causes, in many cases it cannot be determined with certainty that these diseases are the result of exposure to chromium-6 at the POMS sites. For other health problems, such as dental problems, no or insufficient scientific evidence has been found for a possible relationship with exposure to chromium-6.

Responsibilities, working conditions and duty of care

In its capacity as employer, the Ministry of Defence had the responsibility of notifying both employees and occupational physicians of the risks of exposure to chromium-6 containing paint. Most POMS employees indicated that they were not aware of the health hazards related to chromium-6. Furthermore, hardly any of the occupational physicians at the Ministry of Defence that participated in this study knew that there was a possibility that employees were exposed to chromium-6 in the period that the POMS sites were operational. The Ministry of Defence’s prevention and care policy did not comply with the applicable rules, particularly in the early years.

RIVM has conducted research into chromium-6 on behalf of the Minister of Defence. We have published a serie of ten reports on chromium-6 at the POMS sites of the Dutch Ministry of Defence . A combined English summary of the ten reports is available in the report ‘Chromium-6 at the Ministry of Defence’s POMS sites: health effects and responsibilities’.

Chromium 6 aka hexavalent chromium was extensively used in Baldonnel for example in paint strippers like Ardrox 666, paint primers like Metaflex FCR as well as corrosion inhibitors like Mastinox 6856k

Specific hexavalent chromium ingredients used in the Irish Air Corps included

      • Barium chromate
      • Calcium dichromate
      • Magnesium chromate
      • Potassium chromate
      • Sodium chromate
      • Strontium chromate
      • Zinc chromate.

Zinc chromate would have been in the air in the Spray Paint Shop & Engineering Wing hangar any time primer was being sprayed and in many instances personnel carrying out the spraying would have inadequate or no  PPE and personnel in close proximity in the hangar carrying out other tasks  would have had zero PPE and zero awareness of exposure.

Barium chromate & strontium chromate are used in all hangars and some workshops as a component of Mastinox 6856k. This was used with bare hands and likely ingested by some personnel due to inadequate wash facilities. There have been instances where personnel have had parts of their stomach removed from such exposure and have lost all their teeth. 

Sodium chromate is a component of Ardrox 666 which can be seen here dribbling out of the extractor fan in ERF.

Some Safety Data Sheets showing hexavalent chromium ingredients.

it is highly likely that military & civilian personnel in other workshops in the Defence Forces were exposed to chromium 6 / hexavalent chromium.

Secret files reveal Boeing doctor warned of toxic risks, birth defects

In 1980, a doctor wrote factory chemicals would cause “life-long chronic illness, cancer and death.” Lawsuits claim his worst fears came true.

Editor’s note: This is part of ongoing coverage examining the dangers of chemical exposure to Boeing workers in the Puget Sound region, including the Everett plant. According to records obtained exclusively by The Daily Herald, the aerospace company knew for decades — since at least 1980 — that toxins used in its factories posed risks not just to employees, but to their unborn children, too.

EVERETT — On March 18, 1980, one of Boeing’s top doctors made “a rather disastrous attempt” to alert company leadership to a problem that could be fatal.

“During the ‘routine and usual’ course of their employment,” tens of thousands of Boeing workers in the Puget Sound region were being exposed to “probably hazardous” and “certainly uncontrolled” amounts of toxic chemical mixtures, Dr. Barry Dunphy warned in a presentation to the company’s president.

Dunphy scrawled in handwritten slides, using a series of ellipses and line breaks:

“This ……

“….. was not known to be true in previous decades.

“….. is presently occurring without anyone’s real knowledge or consent.

“….. may result in future ‘outbreaks’ of serious illness — including sterility, fetal abnormalities, stillbirth, life-long chronic illness, cancer and death.”

As Boeing’s occupational health manager, Dunphy recommended protecting employees with uniform chemical labeling, medical monitoring, special training and other measures. This could be done, he advised, by building a stronger “industrial hygiene” program within Boeing’s medical department.

His pitch failed.

The doctor later noted, in a tone of defeat, that Boeing President Malcolm Stamper “did not appear at all sympathetic or indeed faintly happy” about having “this organizational problem brought to his attention.” Dunphy’s notes and slides are among scores of internal company documents, now the subject of depositions, in a series of lawsuits that claim his fears came true.

Three families allege Boeing failed to protect its employees from industrial poisons when parents worked in its factories, leading to the birth defects in their children.

The cases span 40 years, involving two fathers employed at the Boeing Everett plant and one mother employed at a Seattle-area factory that has since been shuttered.

Revelations in the cases offer a window into forewarnings that echoed for decades at the highest echelons of one of the world’s largest aerospace companies — and chemical dangers still present at the Everett plant today.

The storm that lies ahead

Dunphy’s warning is one of the earliest internal documents showing some company experts have long suspected the toxins used on its manufacturing floors pose risks not just to workers, but their unborn children, too.

Late last month, the company and Riley reached an out-of-court settlement, according to a joint motion filed in King County Superior Court on Nov. 7. The amount was not disclosed. According to the motion, settlement discussions are still ongoing in the other two lawsuits, filed in 2018.

Boeing, represented by Seattle-based law firm Perkins Coie, has denied that the plaintiffs’ birth defects were caused by chemical exposure and maintains that it has taken adequate steps to protect its employees, according to court filings.

Boeing spokesperson Jessica Kowal said the company does not comment on pending litigation as a matter of policy.

In depositions and court filings, the company has maintained there’s mixed scientific evidence on the connection, and that it’s dependent on the chemical, the manner of exposure and the dose.

The company and the plaintiffs exchanged hundreds of thousands of pages of documents in the discovery phase, alongside more than 30 depositions, according to the notice filed Monday in King County Superior Court.

The Herald obtained transcripts from eight depositions of former and current Boeing employees, including more than a hundred exhibits of internal memos, scientific literature and other company documents.

The plaintiff’s lead attorneys, who specialize in birth defect litigation, attribute the children’s “catastrophic” injuries to a “perfect storm” of toxins from two chemical classes.

Some are heavy metals: cadmium, lead and chromium.

Others are organic solvents, such as toluene, xylene, petroleum distillates, methyl ethyl ketone (MEK), methyl propyl keytone (MPK), and trichloroethylene (TCE).

Some chemicals identified in the lawsuits are still used at the Everett plant. One of them is hexavalent chromium, also called Chromium VI, a long-established poison that Boeing’s own scientists have labeled as the No. 1 chemical of concern, according to the depositions.

It’s the same chemical to blame for the groundwater contamination in Hinkley, California, as dramatized in the film “Erin Brockovich.”

Given the range of factors that can cause reproductive issues, it is difficult to determine whether a child’s birth defect is due to the mother or father being exposed to chemicals, according to the Centers for Disease Control and Prevention. And it’s even harder to pinpoint a specific industrial chemical, given that many of them haven’t been studied for reproductive effects, and industrial workers are usually exposed to a mixture.

Some chemicals in use at Boeing’s plants have been labeled as “reproductive hazards” — sometimes signified by an icon with the gender symbols that can also represent Mars and Venus. But the plaintiffs’ attorneys argue the disclaimer is obscured in the fine print, and the company never adequately explained that term to its workers.

The three plaintiffs’ families had never considered chemical exposure could be a cause of their children’s conditions — until 2016, when the law firm Waters Kraus & Paul ran a radio ad in the Seattle area, seeking workers in the electronics and aerospace industries who had children with birth defects.

“I strongly suspect that there are many other children of Boeing employees who have lived their lives with birth defects,” said lead plaintiff’s attorney Michael Connett, “without knowing that their conditions were caused by the chemicals that their parents were working with at Boeing.”

“It’s really not a question of if,” said Connett, a partner at Waters Kraus & Paul, in an August interview. “It’s a question of how many.”

The plaintiffs have undergone genetic testing and consulted geneticists to interpret the meaning of the tests, Connett said. Other expert witnesses for the plaintiffs include medical doctors, neuropsychologists and an industrial hygienist, a type of specialist that analyzes workplace hazards.

Workers are still at risk, Connett contended, because of Boeing’s failures to communicate the hazards and adequately enforce safety rules. And while working-class mechanics might be willing to roll the dice on their own health, Connett said, the stakes would seem higher if they knew “it’s not just risks to yourselves, it’s risks to your children.”

In his pitch to Stamper over 40 years ago, Dunphy estimated 30,000 employees were “potentially exposed” to “toxic chemical mixtures” and marked about 5 percent of them, or 1,500 people a year, as the “fraction seriously damaged.”

“The bottom line….,” Dunphy typed in an outline of the 1980 presentation, punctuated with irregular ellipses in the text: “Before long we’re going to get screwed because we’ve got an impotent occupational health program …. blind ‘seat of the pants fling (sic) isn’t going to get us through the storm that lies ahead … we need the ‘radar’ of an effective Industrial Hygiene program.”

The other alternatives weren’t good, Dunphy wrote. Among them:

“a) Continue to ignore the problem … ‘hope for the best.’”

“b) ‘play dumb’ ….eliminate hygiene (& Medicine) completely….destroy existing command media dealing with the subject…”

He presented his recommendation to Stamper alongside another doctor, Boeing’s medical director and the general manager of the company’s Seattle services division Art Carter, according to the notes.

“I suspect that this effort will be abandoned indefinitely,” Dunphy wrote afterwards, “…probably permanently….although GM still seems to believe that the concept is a good one…”

“I’ll believe it when I see it.”

Uncontrolled exposures

When Marie Riley was in the womb, her mother Deborah Ulrich worked at Boeing’s Electronics Manufacturing Facility, which once stood on the east side of Boeing Field, also known as King County International Airport.

In the 1980s, it was discovered that groundwater beneath the site was tainted with TCE and other toxic compounds. The U.S. Environmental Protection Agency is overseeing the cleanup.

The plume of contamination extends about a half-mile from where the facility, known as the EMF, was located, under another Boeing plant cleanup site and into the Lower Duwamish Waterway, a federal Superfund site.

Long before the EMF’s demolition in the 1990s, it was a grimy workplace, Connett said.

Fumes drifted from the manufacturing area, where tank lines pumped chemical baths. A degreasing machine heated chemical solvents, giving rise to hot vapors that would clean circuit boards. Chromic acid, a type of hexavalent chromium, was used as an etching agent to carve out circuit boards, he said.

Ulrich was a “floater” who did many tasks. She used the degreaser, cooked light-sensitive film onto copper panels, touched up the patterns on circuit panels with a pen that applied black ink. She cleaned soldered boards by dipping them in industrial solvents, Connett said.

In 1979, about a year before Ulrich became pregnant, Dunphy warned company leadership that Boeing had “no formal training programs in safety and health aspects of hazardous materials, except in radiation health protection.”

In a memo to corporate leadership, he also said that “uncontrolled exposures of employees to hazardous materials is occurring” and “required medical surveillance and examinations are not being conducted.”

The following year, in his failed presentation to Stamper, the doctor warned that “occupational illness among employees is increasingly apparent” and “deviation from legal requirements is increasing.”

Dunphy writes in verbose jargon, but the urgency is apparent.

“What were formerly considered to be ‘insignificantly small concentrations’ of physical and chemical agents in the environment,” he wrote in the presentation, “are now believed to interact over relatively long periods of time with a variable number of poorly defined ‘intrinsic factors’ to adversely effect the reproductive process, and to accentuate chronic (so called ‘degenerative’) disease processes such as cancer.”

“The well documented effects of asbestos, benzene, aniline dyes, and vinyl chloride are current examples,” Dunphy wrote. “Most chromium and nickel compounds, lead, virtually all of our chlorinated organic solvents, and most of our resin systems are under strong indictment by the National Cancer Institute at the present time.”

Michael Krause, who worked for Boeing from 1978 to 1980 as an industrial hygienist, acknowledged “there were issues” with employee chemical exposure. But in a January deposition, he questioned Dunphy’s dire portrayal.

“I think I would just take issue with the implication that — that everything was crazy and uncontrolled and people are sloshing around in chemicals all over the company,” Krause testified. “That wasn’t true.”

Mixed evidence

Boeing’s occupational health and safety program began to take shape in the decade after Congress passed the landmark Occupational Safety and Health Act of 1970. Company policy created in 1974 required “programs, standards, regulations, and practices for the mutual benefit of employees and the corporation as regards health, safety and accident prevention.”

The following year, the company developed standard cautionary labels for hazardous chemicals, in line with guidance from the newly created National Institute for Occupational Safety and Health, according to a court filing by the company.

Warnings included information — “to the extent known at the time” — about whether a chemical caused cancer, genetic mutations, birth defects or other health issues, the company said in the court filing.

Those warnings appeared on federally required safety data sheets for each chemical, available to employees in binders placed throughout the EMF and other factories, the filing says. Boeing also maintains there were safety notices posted around the plant, and workers received “on-the-job” training about chemical hazards.

Those programs have improved over the years, Krause testified, as science on chemical hazards advanced and the company developed a formal “hazard communication” program.

“It’s obvious that new information came out about a lot of different kinds of chemicals over the years, and permissible limits were lowered,” Krause said. “… There was new scientific knowledge all the time, and we tried to react to that.”

In August, when Boeing Senior Toxicologist Brittany Weldon was deposed to speak on the company’s behalf, she acknowledged Boeing’s medical professionals “were of the opinion by 1980 that some chemicals in Boeing’s workplace could potentially cause stillbirths, fetal abnormalities, and infertility, through some exposure routes at certain concentrations or doses for some chemicals in some people.”

As she explained, the impact of a given chemical depends on whether it’s inhaled, ingested or absorbed through skin contact. The body’s process for taking in and metabolizing that chemical varies accordingly.

As early as the 1970s, Boeing had books in its toxicology library that said some organic solvents “were implicated” as causes of birth defects, according to Weldon’s deposition.

The literature references various chemical risks to both a fetus in the womb and to men who can pass harm onto their offspring through what’s known as “male-mediated developmental toxicity.”

“It is likely that solvents affect male fertility and semen quality,” says one of the toxicology library’s books, entitled “Reproductive Health Hazards in the Workplace,” originally published in 1985.

In her deposition, Weldon noted that organic solvents “are a very broad class of chemicals.”

“Not all organic solvents can cause reproductive or developmental toxicity, and I can’t say for certain exactly when Boeing became aware that some solvents can have those effects,” she testified.

“I would add the caveat that they haven’t been specifically linked at Boeing,” she testified. “They have been specifically linked in the scientific literature in animals and animal studies, and that there is mixed evidence.”

Boeing’s attorneys have cited a 1979 memo from a pregnant graphic artist as evidence that the company historically “accommodated requests by employees to be placed on a medical restriction and to be transferred to a different workspace area during pregnancy.”

In the memo written by the Seattle-area employee, she reported she experienced headaches, respiratory irritation and eye irritation while spending hours a day in a poorly ventilated room near a printer that was a source of TCE fumes.

When the employee questioned Dr. Dunphy about the risk, he “stated that there was no 100% sure way of protecting ourselves from the Trichloroethylene fumes,” she relayed in the memo, addressed to management. So he put her on “medical restriction” and moved her away from the source of the fumes, according to her memo.

“I was particularly interested,” the employee wrote, “in obtaining protection for those artists, myself included, who were planning a family in the near future.”

‘Chemicals of concern’

For decades, Boeing has maintained a list of “chemicals of concern” for “reproductive toxicity,” the depositions show. This inventory lists industrial chemicals linked to birth defects via human studies, animal studies or both.

The evolving list is one of many pieces of evidence, discussed in the depositions, that illustrate the company has been tracking and analyzing such risks for years.

In 1986, a company epidemiologist compiled a list of chemicals “reportedly associated with adverse reproductive effects in occupationally exposed men or women.” Among them were cadmium, lead, benzene, toluene, xylene and other solvents.

As of 1993, the list contained information about specific effects of such chemicals, and the extent to which scientific literature confirmed the link.

Cadmium and cadmium compounds, for example, made the 1993 list as hazardous to both the male and female reproductive systems, based on sufficient data from animal studies and limited data from human studies. “Growth retardation, birth defects, functional deficits, infertility and breast milk contamination” were identified as “specific effects” of cadmium.

Various iterations of the Boeing physicians’ guide also reference the reproductive risks of organic solvents and other chemicals. One historical excerpt identifies organic solvents, as a group, as neurotoxins.

“Solvents readily cross the placental barrier, and are suspected of causing adverse reproductive effects which include cleft palate, spontaneous abortion, neonatal sepsis and childhood cancer,” says an excerpt from the “Occupational Health Exam Guide.”

The document is dated 1988.

That was the year that one plaintiff’s father, Shawn Hatleberg, began working as a mechanic for Boeing’s Everett plant.

When filling out a health survey for his placement at the company, Hatleberg checked “yes” next to a question asking whether he was “capable of producing children.”

Another question asked “Are you pregnant at the present time?” (He marked “N/A.”)

There’s a note on the form, in small print: “Scientists generally believe that reproductive cells and the developing embryo and fetus are more sensitive than most normal adults to certain workplace chemicals and several forms of radiation.”

Green mist

Hatleberg helped assemble 747s as a “final body join” mechanic at the Everett plant, Connett said.

As the jets neared the end of production, dozens of people would work to finish the plane at the same time, using a variety of chemical products, Connett said. Some of these mechanics worked inside the aircraft, confined in small spaces with chemical fumes.

The depositions highlight a disconnect between what’s written in handbooks and manuals and what actually happens on the bustling shop floors, where there are hundreds of chemicals in use.

“One of the things that we have learned through the course of discovery is that the first and second line managers at the Everett plant often don’t enforce the safety rules that are in effect,” Connett said. “And as a result, you have a disconnect often between the safety policies as written and the actual workplace practices that are in effect.”

“Unfortunately,” he added, “what we have found is that too often at Boeing, it’s production that they prioritize, not safety of their workers.”

Among the products Hatleberg handled was a primer called BMS 10-11, containing high levels of hexavalent chromium and toxic solvents, Connett said.

For years at Boeing, standard practice was to apply the widely used primer with aerosolizing devices called a pre-val, according to the depositions. Around 1990, this practice was “basically banned” because employees had little control over how much of the chemical spewed from the pre-vals, Krause testified.

Before the ban, mechanics would spray the chemical — some without respirators and sometimes in close proximity of one another — emitting a “green mist in the air laden with hexavalent chromium, toluene and other industrial poisons,” Connett said. The substance also routinely got on Hatleberg’s skin when he was painting it onto surfaces using a brush, according to the attorney.

Not knowing that some hardware was plated with cadmium, some Boeing mechanics placed fasteners in their mouths to free up their hands for the drilling, Connett said.

Dana Ford, father of plaintiff Natalie Ford, worked in the final assembly process when his daughter was conceived in 2013. On the interiors of 777 freighters, he often used some of the same chemicals as Hatleberg.

Two of the chemicals Ford worked with, MPK and corrosion-inhibiting compounds, remain common at Boeing’s factories, even though employees have long-complained about headaches and respiratory issues because of the fumes, according to the depositions.

Included in the depositions are a sampling of audits of Boeing’s Everett plant, from as early as 1989 to as recent as 2019, citing safety violations related to protective gear, employee training and airborne chemical levels.

In 1989, OSHA found levels of chromates and other chemicals in excess of regulatory limits at Boeing Advanced Systems’ Everett Site, according to an audit. Workers weren’t wearing required respirators, gloves and other protective gear, says an internal memo about the audit. Chemicals weren’t properly labeled.

“Employees were not provided with information and training on hazardous chemicals in their work area at the time of their initial assignment or on a continual basis in relation to the completion of the assigned job task,” says the memo.

State and federal regulators assessed over $170,000 in fines.

About the same time, Krause testified, Boeing made a big push to recruit more medical, toxicology, health and safety specialists. In the 1980s, he started his own business as a consultant. He got a call from Boeing.

At the time, the company was in the process of building its chemical inventory. As part of Boeing’s “hazard communication” program, reams of chemical safety data sheets were distilled into more practical “HazCom info sheets,” which outlined a worker’s risk while performing a given job duty or process.

In the 1990s, Krause traveled to shops around Puget Sound, giving two-hour training courses tailored to each one based on workers’ job functions.

“That was the whole idea — and it was kind of brilliant, really — not just throw a bunch of safety data sheets out there, but actually look at what they’re doing, how they’re using chemicals, monitor it so you know what the exposures are,” Krause testified in his deposition, “and then for their shops and their operations, boil it down to a few HazCom info sheets that you’d go over with them.”

Over the years, Boeing has taken steps to reduce worker exposure to some toxic chemicals. It invested in better technology and facility upgrades, while phasing out certain products and practices. Information once kept in binders and handbooks in shop rooms was moved online.

The company instituted monitoring programs to ensure worker exposure levels were below regulatory maximums.

Still, the depositions raise questions about whether training workshops and warnings in the fine print have been enough to convey the true dangers of toxic chemicals to thousands of workers.

In 2021, Boeing toxicologists reviewed health hazards for more than 100 chemical information sheets, according to notes from a meeting of company industrial hygienists.

It was then — decades after scientific literature documented a link between birth defects and organic solvents — that the company added a line to that database entry.

Air Corps failed to comply with Supreme Court order in chemicals exposure case

Former aircraft mechanic Gavin Tobin alleges exposure to dangerous chemicals led to severe health issues

The Air Corps has failed to comply with a Supreme Court order to hand over safety documents to a former aircraft technician suing over his exposure to dangerous chemicals, a judge has ruled.

Gavin Tobin is one of about 11 former Air Corps members who allege continuous exposure to chemicals used in the maintenance of aircraft has led to severe health issues. His case, which was lodged in 2014, has been referred to as test case for the others.

Mr Tobin joined the Air Corps in 1989 as an apprentice aircraft mechanic and was based in Baldonnell until leaving service in 1999. He claims during his service he was exposed to dangerous chemicals on an ongoing basis which resulted in severe personal injury.

Mr Tobin alleges that his employers “failed to provide him with a safe place of work, a safe system of work, safe and proper equipment, appropriate training, and safe and competent co-workers.”

Last month’s ruling by Mr Justice Mark Heslin is the latest is a long-running legal battle over what documents the Air Corps is required to hand over to Mr Tobin as part of discovery in advance of a full civil trial.

The Air Corps was originally ordered by the High Court to make full discovery relating to the chemicals to which Mr Tobin was exposed during this time in the maintenance section. This was overturned by the Court of Appeal. The Supreme Court later confirmed the original order requiring broad-ranging disclosure.

Mr Tobin then received a substantial amount of documents, numbering over 1,200 pages. However these did not include some potentially important files, including safety certificates for the chemicals used by the Air Corps.

The Air Corps claimed it could not hand over the documents as they had been lost or destroyed in the intervening years. It also claimed it is under no obligation to seek replacements for these documents from the chemicals’ manufacturers.

Mr Justice Heslin ruled that this was an unreasonable position and that the Air Corps has failed to make proper discovery of documents.

100 Untimely* deaths recorded in Irish Air Corps toxic chemical exposure tragedy!

Untimely* deaths of serving & former Irish Air Corps personnel

  • 100 verified deaths have occurred in total since 1980 
  • 87 of these deaths have occurred since 2000
  • 62 of these deaths have occurred since 2010
Either the rate of death is accelerating or we are missing many deaths from previous decades or possibly both.
 

3 most significant causes of death

  • 41% of deaths are from cancer
  • 5% of deaths are specifically pancreatic  cancer
  • 29% of deaths are from cardiac issues
  • 6% of deaths are specifically cardiomyopathy related
  • 15% of deaths are from suicide (at least 15 suicides)

*We record untimely as dying at or before age 66 (civilian pension age), average age of death is 53 years. We are counting deaths from medical reasons & suicide, we are not counting accidental deaths nor murder.

We are not stating that every single death is directly due to chemical exposure but many personnel who did not handle chemicals directly were unknowingly exposed due to close proximity to contaminated work locations.

Impact of Firefighting Aqueous Film-Forming Foams on Human Cell Proliferation and Cellular Mortality

Abstract

Objective

Evaluate the toxic effects of Aqueous Film-Forming Foams used by firefighters for Class B fire suppression in human-derived kidney cells (HEK-293).

Methods

Three widely used AFFFs were collected from fire departments and were added to HEK-293 cells in various concentrations. Seventy-two hours post-treatment, cellular proliferation and toxicity were examined using commercially available kits.

Results

All AFFFs evaluated induced cellular toxicity and significantly decreased cell proliferation, even when cells were treated with concentrations 10-fold lower than the working concentration used for fire suppression.

Conclusion

Despite the reduced usage of PFAS-containing AFFFs in the firefighter work environment, the evaluated AFFFs demonstrated significantly altered cellular proliferation, while also inducing toxicity, indicating the presence of toxic compounds. Both stronger implementation of PFAS-containing AFFFs restrictions and robust evaluation of fluorine-free and next-generation AFFFs are warranted.

In Brief

Firefighters are routinely exposed to per- and polyfluoroalkyl substances (PFAS) through the use of Aqueous Film-Forming Foams (AFFFs) for the suppression of Class B fire, which derive from flammable and combustible liquids, such as gasoline and alcohol. The addition of surfactants and PFAS in the AFFFs allows them to form an aqueous film that can extinguish the fire, while also coating the fuel. As such, AFFFs are often used for fire extinction in airports and military bases.

Exposure to PFAS in the general population may arise from ingestion of contaminated food or water, usage of consumer products containing PFAS, such as non-stick cookware or stain resistant carpets and textiles, and inhalation of PFAS-containing particulate matter. Detection of increased serum PFAS concentrations has been linked to an elevated risk for kidney cancer in humans, and firefighters are known to have increased serum concentrations of certain PFAS after attending training exercises. In the same study it was also observed that the average urinary excretions of 2-butoxyacetic acid (2-BAA) a surfactant often added in AFFFs exceeded the reference limit of the occupationally unexposed population, ranging from 0.5 to 1.4 mmol/mol creatinine.

Furthermore, an increased risk of mortality from kidney cancer has been observed in firefighters compared to the U.S. population. The detrimental health effects of PFAS are exacerbated by their increased half-lives in humans. A recently published study examined the half-lives of short- and long- chained PFAS in the serum of 26 airport employees and observed a wide range of half-lives which was dependent on the length and chemical structure of each substance that was examined. Indicatively, the shortest half-life was described for perfluorobutanesulfonic acid (PFBS), while the linear isomer of perfluorooctanesulfonic acid (PFOS) had the longest half-life (average of 44 days and 2.93 years, respectively), findings which are in agreement with other sources in the literature.

One aspect of this phenomenon could be attributed to renal reabsorption, as humans actively transport PFAS in the proximal tubules. A recently published scoping review of 74 epidemiologic, pharmacokinetic, and toxicological studies examined the relationship between PFAS exposure and kidney-related health outcomes. It was observed that exposure to PFAS was associated with lower kidney function, including chronic kidney disease (CKD), and histological abnormalities in the kidneys, as well as alterations in key mechanistic pathways, that can induce oxidative stress, and metabolic changes leading to kidney disease.

The alarming number of studies showcasing the harmful health effects pertaining to PFAS exposure has led to the banning of the production of AFFFs containing highly toxic, long chain PFAS, such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) since 2015. However, this regulation is gradually being implemented across states and little is known about the toxicity of the next generation AFFFs. Based on the above, in the present study we evaluate cellular proliferation and toxicity in kidney-derived cells (HEK-293) that were exposed to three widely used AFFFs.
