German Federal Institute for Occupational Safety and Occupational Medicine mentioned MCS – Multiple Chemical Sensitivity at Thesaurus “Safety and Health at Work”

The Federal Institute for Occupational Safety and Occupational Medicine has published an alphabetical and systematic Thesaurus “Safety and Health at Work”. The Thesaurus has been created in a long-standing cooperation between documentalists, librarians and scientists from the Federal Institute of Occupational Safety and Occupational Medicine.    

The disease MCS – Multiple Chemical Sensitivity (ICD-10 T78.4) is mentioned at the Thesaurus “Safety and Health at Work”, alphabetical Part, Status May 2009, as: 

MCS - Multiple Chemical Sensitivity at Thesaurus

Multiple Chemical Sensitivity (B02.19.00)     

At the systematic Part MCS – Multiple Chemical Sensitivity is found at the category B02:  

“Work related Disease and Occupational Disease/Disease”  

integrated in Part:  

  • B02.19 Other Disease 
  • B02.19.00 Multiple Chemical Sensitivity  

Chronic Fatigue Syndrome (CFS) is integrated analogue.  


MCS is not classified as a mental disease

To clear up occurring doubts, it is to point out that MCS – Multiple Chemical Sensitivity is not integrated into chapter B02.15: Mental diseases, Depression, Neurosis, Post traumatic Stress Disorder or psychosomatic diseases. 

Thesaurus “Safety and Health at Work”

The Thesaurus offers a quick overview on the broad group of themes “Safety and Health at Work”. It contains about 3 500 main keywords and is the joining of the keywords from the two previous Thesauri “Safety at Work” and “Occupational Medicine”. The Thesaurus is based on the practical work of the Library group, documentation at the content development and their research of technical literature. It is a tool for documentation.   

The Thesaurus is intended for all who search for literature about “Safety and Health at Work”. It is supportive for prearrangement of research inquiries at the data pool LITDOK and can be helpful for searching in topic related databases.

The naked Truth about MCS – Multiple Chemical Sensitivity – Including Foreword about German Situation

In June, the online magazine Delirio published an article about Multiple Chemical Sensitivity (MCS), in which Eva Caballé, the brilliant Spanish MCS blogger at NO FUN, presented herself naked in front of the camera and wrote about “The Naked Truth of MCS.”

For other countries, it often looks like chemically sensitive patients in Germany get more medical help than anywhere else since MCS is recognized as a physical disease in our country. It’s true that MCS is registered as a physical disease and has the ICD-10 code T78.4, which lists MCS in the chapter on injuries and intoxicants. MCS is recognized as a physical disability as well (26.14). But the reality for people with Chemical Sensitivity is hard and bitter. Many are fighting at court to get their disability recognized, but even when having numerous medical reports confirming their condition, they usually loose. Because, like in other countries, sickness from chemicals and modern living is not truly recognized but rather swept under the carpet even though we exist and suffer every day.

Further, in Germany, people with MCS are neglected by society. There are people who are homeless because of MCS. Many have lost their jobs or houses. Many are neglected by their relatives because family members do not understand the disease and are not willing to change habits for their sick loved one. Further still, the chemically sensitive people here in Germany are systematically declared mentally ill or having only psychosomatic symptoms.

Medical Assistance focused on Chemical Sensitivity doesn’t exist in Germany. We still have no adequate clinic with special environmentally controlled rooms where the very sick can be treated. Most environmental doctors don’t diagnose MCS because they fear harassment.

MCS is recognized as a physical disability in Germany but the “unseen” barriers are still everywhere. In public buildings you can still find air fresheners in nearly all bathrooms, harsh chemical cleaners all over the building, and perfumed employees everywhere, so none of us can go there without developing severe physical symptoms. Children who are severely chemically sensitive have no chance to visit a public school or university. We have no such thing as scent-free policies in workplaces, schools, public buildings or departments.

We people with Chemical Sensitivity here in Germany can, like people from many other countries all over the world, shake hands with the Spanish MCS sufferers, because we, too, are left naked and without any help. Our chemically sensitive people cry for help without any response each day, too.

The naked Truth about MCS

from Eva Caballé

We are born naked, they give us cologne, perfumed nappies, clothes washed with softeners, creams with all kinds of possible aromas, and they drive us in plastic stroller while we breathe nice polluted air.

We grow up and they make us believe that we can achieve anything we want, that we can write our future, that the happiness is based in buy everything and the state is here to protect and watch over us, although I had my doubts.

One day, you wake up and nothing has sense. You switch on the table lamp and your eyes get burnt; you open the window and perceive new smells that don’t let you breathe. You turn on the radio and the music booms in your head, so much that you fear it will explode. And you don’t have a hangover. It’s worse. It’s been called Multiple Chemical Sensitivity (MCS) and has come to stay. Your body has said “enough”, has been broken and starts rejecting everything that they told you was essential for your happiness. Your life has taken an unexpected turn, your mind changes, your future vanishes, you don’t have physical nor mental energy. The disease forces you to live your life behind a mask and have been in isolation from the outside world.

Multiple Chemical Sensitivity is not strange, nor a minority. It affects to the 5% of the population. It’s a chronic disease, not psychological, which causes symptoms as a response to a minimal exposure to usual and unnecessary chemical products like bleach, air fresheners, perfumes, etc. We live locked in our houses but it’s not necessary to go out to have a crisis. Your neighbour’s cloths airing outside suffocate you, make you feel sick until you loose consciousness, thanks to the wonderful toxic softeners.

The World Health Organization (WHO) don’t recognize MCS as a disease yet, in spite of having in their possession innumerable studies that prove its existence and the European Parliament includes it inside the growing number of diseases related to environmental factors. The reason is the pressure that the chemical and pharmaceutical industry exerts for not recognize it, because MCS is caused by the chemical products that we use to consume. The economical interests in front of our health. In countries which this problem is recognized, like Germany, medical assistance and financial aids towards it are provided, and in some other countries it is being considered at the moment.

And what’s the situation in Spain? We don’t exist to our paternal government. On top of the drama of suffering MCS, they abandon us, without medical assistance and without any right to a disability benefit when we can’t work. They leave us naked and unprotected, like second class citizens, because we’re the evidence that the current model of society has failed, although nobody wants to see it or to take measures to sort it out.

They too steal any hopes we might have of feeling better. Pharmacists finance research only when they can obtain any profit. As a result of this, minority diseases don’t get research, not even MCS, which affect to the 5% of the population. The chemical and pharmaceutical industry knows that we get sick because we’re intoxicated and the key is not any medicine that will make them rich. The key is to change the model of this society, decreasing the big quantity of chemical products to which we’re exposed each day. Obviously, this can’t be known and they try to deny that MCS exists, because their economical interests would be at stake.

The chemical industry, supported by the government, doesn’t have the right to subjugate the population to the involuntary exposure to chemical substances, whose effects are often unknown. When we develop MCS, we must throw away perfumes, softeners, plastics, etc., to be naked again. We born again, but it’s a new life that we don’t choose. We know by the researches that have been done that MCS has genetic components, so not anybody could develop it, although this doesn’t save you to accumulate toxics until you have a cancer or any other disease related to environmental factors.

Those who suffer MCS want the disease to be recognized; we want to have the same rights as the other chronically ill people; we want society to know the risk they are under; we want the government to protect its citizens and prevent them from getting sick at no cost for them.

We don’t want anybody feeling naked again as a result of suffering MCS.

Document and English translation – claissification of MCS as physical disease in Germany

The Department of Health of the Austrian Government recognizes MCS – Multiple Chemical Sensitivity as a physical disease

Just like Germany, Austria is now classifying Chemical Sensitivity / MCS – Multiple Chemical Sensitivity as a physical disease under the code T78.4 of the ICD-10 (the register of diseases). The news comes from a recent letter by the Department of Health of the Austrian Government.

MCS in the ICD-10 in Germany

In a letter dated September 4, 2008 the DIMDI, the Cooperation Partner for Germany of the WHO, wrote that MCS – Multiple Chemical Sensitivity was classified in the register ICD-10 GM which is valid in Germany:

MCS – Multiple Chemical Sensitivity

T78.4…Allergy, not otherwise specified;

Chapter 19 (Injuries, Intoxication and certain other outcomes), Article T66-T78 (Other and unspecified injuries caused by external causes).

MCS in Austria recognized as physical disease

With a letter dated June 24, 2009 regarding “Chemical Sensitivity / MCS – Multiple Chemical Sensitivity (T78.4)”, the Department of Health of the Austrian Government declares that:

In response to your letter dated 4/14/2009 to the Minister of Health Mr. Stoerger, we inform you that the WHO ICD-10 Code modified for Germany from DIMDI is used in Austria as well.

Also in Austria MCS is not a psychological disease

It should be emphasized that the German Institute for Medical Documentation and Information (DIMDI) declared explicitly that there is not any allocation of MCS in Chapter 5 (Mental and behavioural disorders) of the ICD-10-GM. Thus, the debate about MCS as mental illness is at an end.

In Germany doctors who document the diagnosis and the hospital administrations work under the Social Security Code V, which states that the diagnoses have to be made according to the systematic list of ICD-10-GM. Thus, the ICD-10 classification is legally binding.

The Department of Health of the Austrian Government refers in the letter that MCS – Multiple Chemical Sensitivity is recognized in Austria as a physical disease, because also there it will have the code T78.4 in the ICD-10.
