Taking the Irish Air Corps a stage further in their Jet fuel toxic hazard knowledge!

The below post is taken from the Agency for Toxic Substances and Disease Registry (ATSDR)  which is a part of the United States Centers for Disease Control and Prevention (CDC). 

This Public Health Statement is the summary chapter from the Toxicological Profile for JP-5, JP-8, and Jet A fuels. It is one in a series of Public Health Statements about hazardous substances and their health effects.

A shorter version, the ToxFAQs™, is also available. This information is important because this substance may harm you.

The effects of exposure to any hazardous substance depend on the dose, the duration, how you are exposed, personal traits and habits, and whether other chemicals are present.

Some workers may be exposed to JP-5, JP-8, or Jet A fuels through their skin if they come into contact with them without adequate protection from gloves, boots, coveralls, or other protective clothing.

This Public Health Statement summarizes the Agency for Toxic Substances and Disease Registry’s findings on JP-5, JP-8, and Jet A fuels, tells you about them, the effects of exposure, and describes what you can do to limit that exposure.

If you are exposed to JP-5, JP-8, or Jet A fuels, many factors determine whether you’ll be harmed. These include how much you are exposed to (dose), how long you are exposed to it (duration), and how you are exposed (route of exposure). You must also consider the other chemicals you are exposed to and your age, sex, diet, family traits, lifestyle, and state of health.

What are JP-5, JP-8, and Jet A fuels?

JP-5 and JP-8 stand for jet propellant-5 and jet propellant-8. Propellants are substances that move other objects or give thrust. JP-5 and JP-8 are used as military aircraft fuels. They can also be used for fueling land vehicles and as a fuel source for heaters and lights.

Jet A is the type of fuel used in civilian aircraft; however, the U.S. Air Force has recently started using Jet A (plus certain additives) for flying in the continental United States. JP-5, JP-8, and Jet A fuels are colorless liquids that are flammable and smell like kerosene. The fuels are made from chemical compounds called hydrocarbons, which are found naturally in the earth as crude oil. Hydrocarbons are compounds that contain only carbon and hydrogen. The crude oil is refined into a number of different types of fuel.

Jet A, JP-5, and JP-8 fuels may also contain various additives such as antioxidants and additives to prevent icing in the fuel lines.

What happens to JP-5, JP-8 and Jet A fuels when they enter the environment?

JP-5, JP-8, and Jet A fuels are made up of hundreds of hydrocarbon compounds; many of these hydrocarbons are also present in gasoline. These hydrocarbons can be grouped into several classes of chemicals which have similar chemical properties. The different chemical classes can behave differently when they enter the environment.

For example, some of these can easily evaporate into the air during aircraft loading and unloading operations or as a result of their normal use as a jet fuel for civilian or military aircraft. Some may also evaporate when jet fuels are spilled accidentally onto soils or surface waters. Other chemical classes are more likely to dissolve in water following spills to surface waters or leaks from underground storage tanks. Some chemical classes found in jet fuels may slowly move down through the soil to the groundwater, while others may readily attach to particles in the soil or water. Once attached in water, these particles may sink down into the sediment.

The chemicals that evaporate may break down into other substances in air by reacting with sunlight or other chemicals in the air. The chemicals that dissolve in water may also be broken down into other substances by microorganisms found in water and sediment. However, this may take many years to occur, depending on the environmental conditions. Some chemicals that attach to soil or other matter (for example, marsh sediment) may remain in the environment for more than a decade.

Some of the chemicals in jet fuels may be detected in fish and aquatic organisms after an accidental release into a lake, river, or stream. These hydrocarbons are not expected to persist in aquatic organisms.

How might I be exposed to JP-5, JP-8, and Jet A fuels?

It is unlikely that you will be exposed to JP-5, JP-8, or Jet A fuels unless you work with jet fuels or live very close to where they are used or were spilled.

Exposure to jet fuels can occur if you have skin contact with soil or water contaminated from a spill or leak. You may also be exposed to JP-5, JP-8, or Jet A fuels if you swim in waters where jet fuels have been spilled. If jet fuels have leaked from underground storage tanks and entered groundwater, you may be exposed from contaminated well water. You might breathe in some of the chemicals evaporating from a spill or leak site if you are in an area where an accident has occurred.

Workers involved in making or transporting jet fuels, aircraft or fuel tank maintenance, or in refueling aircraft that use JP-5, JP-8, or Jet A fuels may be exposed to some of the chemicals that have evaporated from the fuel.

Workers in the vicinity of an aircraft during cold engine startup may also be exposed to airborne jet fuels.

Some workers may be exposed to JP-5, JP-8, or Jet A fuels through their skin if they come into contact with them without adequate protection from gloves, boots, coveralls, or other protective clothing.

How can JP-5, JP-8, and Jet A fuels enter and leave my body?

The chemicals in JP-5, JP-8, and Jet A fuels can enter your body through your lungs, digestive tract, or skin. We do not have information on how much of the chemicals in JP-5, JP-8, or Jet A fuels can pass into the bloodstream, but we do know that large amounts of some of the chemicals in jet fuels can easily do so.

Studies examining the absorption of jet fuels through the skin have shown that damage to the skin and the longer jet fuels stays on your skin will increase the amount of chemicals that will enter your body.

Once jet fuels enter your body, the chemicals in the fuel will be distributed throughout your body. A number of the chemicals in jet fuels were found in the blood, fat, brain, lungs, and liver following exposure to JP-8 in air.

Some of the chemicals in JP-5, JP-8, or Jet A fuels will be broken down in the body to form other chemicals. The chemicals in JP-5, JP-8, or Jet A fuels will be eliminated from the body in the urine, feces, or breath.

How JP-5, JP-8, and Jet A fuels affect your health?

The health effects of JP-5, JP-8, and Jet A fuels depend on how much of these fuels you are exposed to and for how long.

We know very little about the human health effects caused by JP-5, JP-8, or Jet A fuels. A few studies of military personnel have provided suggestive evidence that JP-8 can affect the nervous system. Some of the effects that have been observed in humans include changes in reaction time and other tests of neurological function.

Humans who accidentally ingested kerosene, a fuel oil similar in composition to JP-5, JP-8, and Jet A fuels, were reported as suffering harmful effects on the respiratory tract, gastrointestinal tract, and nervous system. The observed effects included cough and difficulty breathing, abdominal pain and vomiting, drowsiness, restlessness, and convulsions.

Studies in laboratory animals have examined the toxicity of JP-5, JP-8, and Jet A fuels following inhalation, ingestion, or dermal contact. In most cases, the levels tested in laboratory animals are higher than levels the public might encounter through dermal contact with contaminated water or soil or by drinking contaminated water.

Health effects of JP-5, JP-8, or Jet A fuels observed in these studies include damage to the liver, decreased immune response, impaired performance on neurological function tests, and impaired hearing.

Dermatitis and damage to the skin have also been observed in laboratory animals following dermal contact.

There are no reliable studies of cancer in humans exposed to JP-5, JP-8, or Jet A fuels. A few studies that examined the possible association between exposure to various types of jet fuels or to kerosene and various types of cancer did not provide conclusive results. Because the studies involved exposure to several fuel types and there was no information on exposure concentrations, these studies were not considered adequate to assess the carcinogenicity of JP-5, JP-8, or Jet A fuels.

No inhalation or oral studies evaluated the carcinogenicity of JP-5, JP-8, or Jet A. No increases in tumor incidences were observed in rats administered kerosene by a feeding tube for 2 years. JP-5 applied to the skin for 2 years was not carcinogenic in mice. Increases in skin tumors were observed in mice dermally exposed to Jet A for 52–62 weeks; however, tumors were only observed at concentrations resulting in damage to the skin. Similarly, increased numbers of skin tumors were observed in mice that received applications of undiluted kerosene on the skin for 2 years, but this occurred only in the presence of skin damage.

The U.S. Department of Health and Human Services (DHHS) and the EPA have not classified JP-5, JP-8, or Jet A fuels as to their carcinogenicity.

The International Agency for Research on Cancer (IARC) has classified JP-5, JP-8, and Jet A as Group 3 carcinogens (not classifiable as to their carcinogenicity to humans).

How can JP-5, JP-8, and Jet A fuels affect children?

Exposure JP-5, JP-8, or Jet A fuels mainly occurs in occupational settings where children are unlikely to be exposed. No studies examining the health effects of JP-5, JP-8, or Jet A fuels in children were found. There are a number of reports of accidental kerosene ingestion in children in developing countries where kerosene may typically be stored in containers and places easily accessible to children. Some of the more commonly reported effects include coughing, pneumonia, shortness of breath, vomiting, fever, unconsciousness, drowsiness, and irritability. These effects are similar to the effects seen in adults who ingest kerosene.

Studies in laboratory animals exposed to JP-8 during pregnancy did not find birth defects in the newborn animals. However, some effects on muscle coordination and immune function were found in the offspring.

How can families reduce the risk of exposure to JP-5, JP-8, and Jet A fuels?

If your doctor finds that you have been exposed to significant amounts of JP-5, JP-8, or Jet A fuels, ask whether your children or unborn baby might be at risk. Your doctor might need to ask your state health department to investigate. It is unlikely that you or your family will be exposed to JP-5, JP-8, or Jet A fuels. Jet fuels are not likely to be common contaminants in foods or drinking water.

If you get JP-5, JP-8, or Jet A fuels on your work clothes, you should change your clothes before leaving your job and returning home.

Are there medical tests to determine whether I have been exposed to JP-5, JP-8, and Jet A fuels?

Many of the individual chemicals found in JP-5, JP-8, and Jet A fuels and their breakdown products (metabolites) can be measured in blood and urine. Finding these chemicals does not mean that you were exposed to jet fuels because these chemicals may have come from a different source including exposure to gasoline fumes when pumping gas. The levels of these chemicals in your body cannot predict the kind of health effects that might occur or whether you will have any effects. JP-5, JP-8, and Jet A fuels and their metabolites leave the body fairly rapidly and tests to detect these chemicals need to be conducted within days of exposure.

It is pretty clear from reading interactions between Air Corps personnel and the Air Corps Formation Safety Office that the risk of injury from inhalation and absorption of jet fuel simply is not understood.

The consequence of this is that the actual risks are downplayed with risk assessments for fuel handling operations being declared as “Low Risk”. Risk assessments that are declared to be “Low Risk” are great for the FSO because they mean no further steps need to be taken.

A risk assessment completed by a suitably qualified person with the correct vigor will take into account the need for adequate PPE and also the need for risk specific health surveillance.

Immunotoxicology of JP-8 Jet Fuel

Abstract

Chronic jet fuel exposure could be detrimental to Air Force personnel, not only by adversely affecting their work performance but also by predisposing these individuals to increased incidences of infectious disease and cancer.

Chronic exposure to jet fuel has been shown to adversely affect human liver function, to cause emotional dysfunction, to cause abnormal electroencephalograms, to cause shortened attention spans, and to decrease sensorimotor speed.

Currently, there are no standards for personnel exposure to jet fuels of any kind, let alone JP-8 jet fuel. Kerosene based petroleum distillates have been associated with hepatic, renal, neurologic and pulmonary toxicity in animals models and human occupational exposures. The U.S. Department of Labor, Bureau of Labor Statistics estimates that over 1.3 million workers were exposed to jet fuels in 1992. Thus, jet fuel exposure may not only have serious consequences for USAF personnel, but also may have potential harmful effects upon a significant number of civilian workers.

Short-term 7 day JP-8 jet fuel exposure causes lung injury as evidenced by increased pulmonary resistance, a decrease in bronchoalveolar lavage concentrations of substance P, increased wet lung body weight ratio, and increased alveolar permeability. Long-term exposures, although demonstrating evidence of lung recovery, results in injury to secondary organs such as liver, kidneys and spleen.

The Irish Air Corps uses JetA1 with added fuel system icing inhibitor (FSII) which while being very similar to JP-8, is not identical as it is lacking some additives used in very high performance military engines.

But is very similar and almost all the health concerns related to JP-8 would be common to JetA1.

The Formation Safety Office at the Irish Air Corps believe refueling to be a “low risk” activity yet it appears to be driving IBS/ IBD havoc amongst personnel in Baldonnel who handle fuel.

Some selected information from a HSA FoI request regarding the Irish Air Corps Toxic Chemical Exposure Scandal

Today we present to you with some selected excerpts from an extensive FoI request from the  Health & Safety Authority regarding their investigation into exceptionally poor chemical Health & Safety practices at the Irish Air Corps.

This investigation, the results of which are contained below, occurred after 10 years of annual inspections by the State Claims Agency section of the National Treasury Management Agency. It should be noted that personnel in the NTMA were entitled to performance related gratuities for supposed improvements to the risk profile of of the Irish Air Corps.

A full page of relevant chatter is included in a 27 page PDF here including:
  • Original response from Formation Safety Office (FSO) personnel towards an elected PDFORRA rep who raised initial chemical concerns.
  • PDFORRA rep being told to tell his members to contact their own unit safety reps and for PDFORRA rep to use “proper channels”
  • Formation Safety Office Sgt requesting employment of an occupational hygienist as “we do not have the competency required on site to assess this”
  • FSO OC responding that funds for an occupational hygienist had been approved.
  • PDFORRA letter to Defence Forces SO Health & Safety regarding concerns about the provision of adequate health surveillance for members in the Air Corps
  • Letter to PSO/ACOS & GOC Air Corps from Formation Safety Officer reference to PDFORRA letter containing a number of misleading and / or factually incorrect statements. The line “All the control measures in place meet and exceed best industry standards” has not aged very well.
  • Some concerns regarding exposure to fuel & exhaust fumes amongst FTS personnel.
  • A stark admission that FTS personnel were not made aware of the dangers of the chemicals used for air display coloured smoke.
  • SDS for Keystone Liquid Orang Oil used to make the orange smoke
  • Some concerns regarding occurrence of IBD in Refueler Section personnel
  • Letter from Formation Safety Officer stating he believed the risk of exposure is low and that there is no issue with provision of PPE
  • Unsigned, inadequate and therefore invalid Risk Control Sheet showing a LOW risk rating (every single one of these for any chemicals was LOW).
  • HSA letter to Air Corps after inspection prompted by chemical injury of 2 personnel that was not reported.
  • Letter from AC Formation Safety Advisor in response to HSA intervention giving a timeline to comply with measures that were a legal obligation since 1989.
  • We have redacted the names of those involved.

 

 

 

Fourth study of mortality and cancer incidence in aircraft maintenance personnel: a continuing study of F1-11 Deseal/Reseal personnel 2016

Summary

From 1974 to 2000, the Royal Australian Air Force (RAAF) put in place formal Deseal/Reseal (DSRS) programs, in addition to informal repair methods, to correct fuel leaks in Australia’s F-111 fleet of aircraft. These programs were undertaken at RAAF Base Amberley in Queensland, and were suspended in early 2000 due to health concerns among DSRS personnel. A series of inquiries, investigations and scientific studies were commenced to determine the extent and impact of those health concerns.

As part of those investigations, the Mortality and Cancer Incidence Study (MCIS) was started to answer the following research question: did RAAF personnel involved either directly or indirectly in the F-111 DSRS maintenance programs (the DSRS-exposed Study Population) experience higher levels of mortality or cancer incidence compared with two groups of non-exposed RAAF personnel (the Comparison populations)—the RAAF Base Amberley (non-technical) Comparison Population and the RAAF Base Richmond (technical) Comparison Population?

Key findings

The results of the 4th MCIS show that involvement in the DSRS programs at RAAF Base Amberley was associated with a statistically significant 20–30% increase in the rate of cancer diagnosis, compared with both Comparison populations.

Involvement in the DSRS programs was also associated with a statistically significant 27% decrease in mortality compared with the Amberley Comparison Population.

*****

The key takeaway here is that a statistically significant 20-30% increase in cancer was turned into 27% lower mortality by awareness, vigilance and a coordinated medical response. 

  • Medical treatment for a range of conditions
  • Counselling through Open Arms – Veterans & Families Counselling;
  • Participation in Open Arms – Veterans & Families Counselling coordinated programs, including the Lifestyle Management Course and Heart Health;
  • Eligibility to participate in the Better Health Program – a cancer screening and disease prevention program; and
  • approved travel to attend medical consultations and counselling sessions and healthy lifestyle programs through Open Arms – Veterans & Families Counselling.

The policy of successive Taoisigh, Tánaistí, Ministers for Defence, Chiefs of Staff and Director Generals of the Department of Defence was, and appears still to be, to let personnel suffer and die unnecessarily without any targeted intervention whatsoever by the state.

Death rate among former Irish Air Corps personnel needs to be examined, expert says

Whistleblowers blame premature deaths on exposure to toxic chemicals without PPE

The rate of deaths among former Air Corps personnel who have been exposed to dangerous chemicals needs to be examined by the Government, a leading public health expert has said.

Anthony Staines, who is professor of health systems at DCU, said the number of former personnel who have died prematurely appears to be higher than what would be expected for that population.

Protected disclosures about the exposure of aircraft technicians to dangerous chemicals at Baldonnel Airfield were first made to the Government in 2015.

One of the whistleblowers, former Air Corps technician Gavin Tobin, has been keeping track of serious illnesses and premature deaths in former colleagues which he believes may have been caused by exposure to these substances without personal protective equipment (PPE).

As of Friday he had recorded 96 premature deaths resulting from a variety of illnesses, including heart problems and rare forms of cancer. The average age of those who died is 52, he said.

Prof Staines told The Irish Times he has examined the figures provided by Mr Tobin and found them “surprising”.

He said the death rate is not particularly out of step with the general population but that “this is a group of people where the death rate should be low!”.
