Fiberglass inhalation

Hi.

I was exposed to fiberglass as well when it fell out of the ceiling. I inhaled it and since then I have been sensitive to smoke and car fumes. I also keep feeling like something is stuck in my throat and have throat pain which increases when i speak as well as trouble breathing.  I feel the restriction in my chest when i walk, like a tightness. It get worse when it rains. I went to a pulmonologist who is now refering me to a cardiologist. I couldnt find any test that would show fiberglass. I have had MRI and CT scans as well as ultrasounds. The ultrasound showed swelling around the throat area.I had been referred for a doplar ultrasound. My throat has been teste and no pathogens found, not bacteria or virus but they didnt test for debris. I have used a lot of natural remedies and well as inhalers and other medications. I there a test that would sample the debris in my throat. .


This discussion is related to I inhaled Fiberglass Insulation -- Please Help!.

Hello and hope you are doing well.

Fiberglass is a silicate fiber and can reduce lung function and cause inflammation. It can also cause skin, eye and throat irritation. At higher exposure levels, fiberglass also has been associated with skin rashes and difficulty in breathing. Was the lung function tests normal?

Fiberglass emits a synthetic material called styrene, which is a possible carcinogenic. Styrene and its breakdown products can be measured in your blood, urine, and body tissues. Styrene leaves your body quickly. If you are tested within one day, the actual amount of exposure can be estimated. However, it is difficult to predict the kind of health effects that might develop from that exposure.

Hope this helped and do keep us posted.

Thank you for that information. The breathing test did show reduced lung funtion. I would like to know of case studies or real life cases of how people treated this condition and how living with it long term affected their lives.

Hello and hope you are doing well.

To begin with it is mostly prevention. Always wear a dust mask in areas where exposure is likely, to help avoid inhaling glass fibers. The damage which has already been done will be there. Treatment is usually symptomatic. Antibiotics for infections and bronchodilators for bronchospasm. And of course avoidance of smoking to prevent further damage to the lungs. To improve lung function practice breathing exercises.

Hope this helped and do keep us posted.

The exposure was done without warning. Several people were affected. Many reporting same or similar symptoms. I was/am on antibiotics, nasal sprays, inhalers, steroids and other drugs to the point that I developed edema and acid reflux. I never smoked in my life and never liked how it smelled but now it affects me to the point of feeling like air was sucked out of my lungs, loosing my breath and feeling faint, just by someone passing by.

I did find some information,

Health hazards associated with moldy fiberglass in buildings, with focus on fiberglass insulation, fiberglass fragments, fiberglass in heating and air conditioning duct work, and invisible but toxic mold growth in fiberglass which has been wet, exposed to high humidity, or exposed to other moldy conditions. Small glass fiber fragments are easily "lost" in other non-fungal granular debris in building dust. Level of airborne fiberglass in buildings may be faulty if the methods used to screen for fiberglass fragments do not include small, even sub-micron particles along with the common large particles.Fiberglass fragments are inorganic material typically from fiberglass insulation; depending on their size and quantity these may be a respiratory irritant or may contribute to more serious health concerns. It is possible that small fiberglass particles in air may constitute a meaningful health risk which has not been explored.

There are conflicting reports on breathing exercises and breathing deeply if there are fiberglass particles lodged in the lungs or throat. Since the particles don't pass out of the body as the whole fragments, it may cause the particles to get lodged deeper into the lung tissue and cause other issues. I guess the hope is that the particles would migrate safely into the blood stream and not get lodged where it could cause clots, cysts or cancer.

Also fiberglass is glass fibers and they cut. I wonder if some of the sensitivity is capillaries or veins being exposed or cut by the lodged particles creating a direct path for infections into the blood stream. Many people reported have to increase hand washing and having to be very particular with what they eat because eating any thing not fully cooked or slightly contaminated creates an immediate sore throat in addition to the existing throat pains.

Common symptoms of fiberglass overdose
•persistent, dry, hacking "barking" cough
•sore throat, bloody taste in throat or blood in sputum
•bloody nose
•persistent, occasionally very severe, sinusitis and rhinitis which does not respond to common medical treatment,
•especially treatment for allergies,
•persistent, occasionally severe respiratory infections which, again, do not respond to common medical treatment,
•headaches, nausea, dizziness, insomnia, irritability, depression,
•asthma-like breathing attacks or constant wheezing,
•other allergy-like symptoms (which do not respond to allergy treatment),
•"reactive airway disease,"
•swollen, red, watery, infected eyes,
•skin infections, ranging from mild to very severe, requiring hospitalization,
•extreme sensitivity to everyday amounts of ambient pollutants, especially: cigarette smoke, car exhaust, perfumes and colognes, some cleaning products, paints and varnishes, new paneling, cabinetry or furniture made with particle board or strand board, new cars and other new plastic, foams used for furniture and bedding, new carpeting.

Just out of curiosity, are you feeling better. I may have a similar problem, and am curious to know if you were treated and are feeling better, if time eventually worked it out of your system or if it has continued to be a nuisance.

Fibreglass is an irritant, but the way the fibres break up, they cannot get lodged into the Alveoli.  So in time technically, they should be coughed up.

It is the chemicals used to make the fibreglass that causes the irritations.

I would like the see the research study that you are speaking of that shows fiberglass or tissue penetrating fiberglass passes 100% out of lungs. I would like to see the study showing micron and submicron as well as whole fiber particles were inhaled then all passed out of the lungs.
Many times foreign bodies have to be manually removed from tissue. However, penetrating foreign bodies are more difficult to remove. Foreign bodies don’t all pass through the body is as you suppose. Ask any soldier wounded by shrapnel, miner, or exposure victim. Additional reports have demonstrated subcutaneous soft tissue foreign bodies from splinters to bullet fragments found years after the traumatic event.
Patients with glass embedded in a wound are more likely to report the sensation of foreign bodies. Unrecognized bronchial foreign bodies cause irreversible changes in the airways. Some foreign bodies may move from the throat into the bronchial branches. This can cause the patient to cough, but the foreign body remains trapped in the lung.
All glass is radiopaque; and there is limited ability for radiography to detect glass fragments smaller than 2 mm. Many foreign bodies are surrounded by a hypo echogenic area representing inflammation.
Most of the foreign bodies were found in the right bronchus. The interbronchial foreign bodies were recovered by bronchoscopy, while some were recovered during emergency tracheotomy and bronchotomy.
The exposure that I was in, included the blowing of the foreign bodies by fans causing them to become projectile. Everyone was coughing, causing a greater exposure and a greater chance if the substances to be imbedded into the throat and lungs. However, you are correct when saying the chemicals from the fiberglass adds to the damage to the body and tissues.

Thank you for your concern. No I am not feeling or doing much better. I have continuous pain and discomfort to my throat and lungs. I have trouble breathing, tightness of chest, chest pain, squeezing of the chest, heaviness of the chest, shortness of breath, labored breathing, etc. I am on asthma medication, finally one that does not cause many side effects, but I am not sure if it is actually working. Some days are better than others. I have throat pain, a feeling that something is stuck in my throat, increase pain, feeling of a sore throat and swelling with prolonged talking which if continued develops into hoarseness, difficulty swallowing and difficulty speaking with a greater chance of infection. When I speak “too much” or sing my voice breaks. It has affected my work and employment outlook. I am constantly fatigued and have not been able to do a full schedule of house work in the years since the exposure. I have other symptoms including drug reactions. Recommended tests would be a CT, ultrasound, Doppler ultrasound, and fluoroscopy of the neck; bronchoscopy of the lungs; MRI of the brain w/contrast; Methyl Ethyl Ketone blood test; a toxicology of suspected chemicals/substances using blood, urine and tissue samples sent to a lab that does submicron testing for debris; Body Burden testing. Recommended doctors would be top rated ENT, Neurologist, Pulmonologist, Medical Toxicologist, Primary Care Physician and if you can find doctor with a past history of exposure cases even better. I pray you receive good care and assistance. Let me know how you progress or if you find any information in this issue that may help. Thanks.

Sorry to hear that you are still very unwell.

According to MedHelp Policy I am not able to write the web address that I got my information from.  You can type in your address bar "fibreglass in lungs" and you will get sites that come up with the information.  Toolboxtopics ******* typed into your address bar should bring up the information that I read.  There is also information on the American Lung Association site.

There is another site with regard to finer fibreglass particles that is used as insulation in fridges and cabinets and the very fine particles can enter the Aveoli.

What I read was that when asbestos is inhaled, the fibres as very small and when they reach the Alveoli, the Alveoli which are the little sacs in the lungs close around the dust particles.

Because fibreglass is a much larger particle, it does not get into the Alveoli sac.  That doesn't mean it doesn't cause other problems.

I agree with you that what goes into the body is not always excreted.  I have a cactus needle embedded in my body that has been there for the last 30 years causing a painful lump.

Wishing you a speedy recovery.

Thanks for all the posts,
I hope you all are doing ok,
I recently had an exposure to what i believe may be airborne moldy fiberglass, when a maintenance worker tore out some fiberglass insulation from an antique oven (my original guess was it asbestos, but it tested negative). I've had symptoms similar to yours, although less severe.

Initially I had an inflamed nasal passage and throat, and slightly inflamed eyes. Then blood in sputum I sneezed up, and chest pain, shortness of breath, and sensitivity to smoke, etc.

I hope to read any updates you have. Best wishes

Sorry the hear about your exposure. I hope you feel better and get quality care. Try RateMds, Healthgrades or Vitals for help finding good doctors. InspectApedia has some information on fiberglass and mold exposure. Each substance by it self has damaging effects but when you combine them the way it affects the body is multiplied like in all chemistry; vinegar or baking soda acts a certain way until you combine them. Please post any observations of findings by you or your doctors. More studies need to be done about the combination effects of substances that naturally occur together; exposure to dust, dust mites, insect waste, fiberglass and mold is a different exposure to just dust and dust mites. Thanks. GOD bless.

Other symptoms that may be related are nodules in the thyroid with a negative thyroid issue(found with an ultrasound) gallstones, bladder cystitis, black/dark stool, lower back pain, abdomen pain, fatigue. I recommend that exposure patients journal their symptoms at least for a few month to see how your symptoms develops and to not miss any seemingly unrelated symptoms.

I have read this and found it very interesting....  

In past almost two years....  I have had chronic sinus infections, multiple antibiotics, steroids, inhalers, breathing treatments.  Two sinus surgeries in past year, lung xrays, EKG, Stress Test, Breathing test (which revealed low intake on inhale), Allergy Test, Endoscopy, Throat ballooned open to stretch opena constriction.... (last two year just this past week).  I also have inquirred with HVAC company about upgrade unit it is past its life expectancy......  one company pointed out that fiberglass insides in duct work was detoriating rapidly.  Research and seeing that this could be cause.  Note I just married on 10/06/2012 but was living there at least 6 months before wedding.  

Where do I go from here?

I have constant nasal type drainage, feeling of lump in throat, heaviness in chest, sometimes to point of a pain in center of chest between boobs and at times goes clean through to my back.  I have trouble sleeping, even with medication, and I am exhausted always.  I get winded carrying a load of laundry up the steps.....  I am almost 40, 5'9" in height and just under 150 lbs., female.....  so its not a weight issue.  

Any help would be appreciated?

Hello, my wife and I moved into our new house 1 year ago.  I have a daughter that just turned 3 and we are expecting another daughter in the next few days.

I recently discovered our ac/ heating return vent was not installed properly and was sucking in all the fiberglass insulation from our attic for the past year.  My 3 year old daughter had constant health problems since we moved in and we just thought it was allergies from the air outside of the house or pollen.  Some of her symptoms are coughing, running nose, irritation to eye and itchy skin.  Has anybody experienced or know any dangers to what long term exposure to fiberglass insulation can cause?

I haven't yet found any real quick fix or cure treatment for fiberglass exposure. Detoxing may help with the symptoms and prolong the development of cancer. Aspirin keeps the blood thin and help any dislodged floating partials circulate out of the body as well as keeping fresh blood to the injured sites. Omega 3.6.9 is good for the brain issues as well as Turmeric. Being careful to rest and de-stress. Fresh vegetables, herbs, roots, fruits and leaves can help keep the body going and help prolong the turn for the worst. I haven't found any procedure that would take the embedded glass out. Please be aware that fiberglass particles are not on their best behavior and do not just leave the body quickly  and orderly as some articles suppose. I can circulate to other parts of the body like the brain.

Long term verses short term exposure would be a mute point because it really about the type of exposure. Working in fiberglass with proper gear and clothing for years could be listed a "long term" exposure with no side effect. When in reality the only exposure that should be counted for health purposes is when people come in contact with fiberglass without proper protection. How they were exposed, what other contaminants were attached to the fiberglass and how the exposed reacted to the exposure play a role. For example: Was the fiberglass blowing around, drifting down or being walked on? Was there mold, insect droppings, rodents droppings, other chemicals? Did the person cough with their mouth open, rub their eyes, took deep breaths to sneeze or did they cover their mouth, never touched their face, took a shower right away? It doesn't take long to have a massive damaging exposure but the build up effect over time is just as harmful.

Here are a few of the list of medical issues caused by fiberglass exposure:

skin, eye and upper respiratory tract irritation
rash
red eyes, irritated
soar nose
soar throat
Asthma and bronchitis like conditions (reduced lung function)
inflammation
stomach irritation
reactions to the formaldehyde, styrene and methyl ethyl ketone in fiberglass
tiredness
brain cancer
insomnia

I am 49 years old and have been working with fiberglass for the last 29 years building various projects, mostly boats.
I don' t wear any protection, which is probably not a good idea, but I sand, grind and cut fiberglass all the time.
I crawled through old house ceilings, on my belly, in fiberglass insulation, more than a few times.
I have not had any health related issues because of the fiberglass.
If I were you I would start looking at other possible causes for your illness.

Avatar_n_tn
If you had no issues from fiberglass, why are you searching for medical information on fiberglass exposure. Just looking for something random to dispute?

It would be very dismissive to say since you didn't get hurt from fiberglass anyone else who did, somehow must be affected by something else.

Perhaps you also smoked for years and didn't develop cancer so everyone else must have gotten cancer from something else.

I agree with dogooder24.  Just because YOU do not have a problem now, does not mean someone else doesn't.  And it does not guarantee that you won't get a lung disorder as you older.

You have risked your life by not wearing protection whilst working.  This is not a good advert for young men and women who work in those types of industries.  Sanding is in fact one of the worst things you can do without wearing breathing protection.  Any type of irritant, smoke, sand, silica, or fibreglass is not good news for the lungs.  The very minute particles get trapped in the alveoli.  The body's natural response is to cough to try and get rid of the irritant, but some particles are so minute and have sharp edges that they get lodged inside the Alveoli which is the cause of lung disease.

If you have or have had a cough, asthma, bronchitis, discomfort in the chest, etc., then you do have a lung disorder which may be mild at the moment, but would highly likely get much worse as you get older and the more exposure you have to the irritants the worse you will get.

My uncle used to polish off the built up sand on shells and make jewellery from the polished shells - health and safety at work was not well known when he did that type of work which was in fact his hobby.   After many years of doing this he eventually died from lung cancer as a result of the build up silica in Alveoli in his lungs.

I think all he's saying is in his opinion it's unlikely considering he is a human being who has had massive and prolonged exposure to fibreglass and no symptoms whatsoever perhaps consider other possibilities.

Anyhow I've not been careful enough over the years working with fibre glass and the other days a fan blew some directly at me and I breathed it in. I also breath in dirt a lot as I lay turf etc. for a living. Currently I'm suffering with breathing difficulties and a persistent itchy throat and cough and a bit worried.

Good luck to all!

I had a similar situation with inhaling fiberglass insulation, some was in my throat and some was in my lung... It was two different occasion on the same job site (I worked in home remodeling)

How I got rid of the one in my throat, was I took a handful of activated charcoal and I letterly felt the fibers get pulled down into my stomach. It's not pleasent because I felt a sharp pain in my intestants, but it was miraculous how instant it worked!

As far as the one in my lung, it dissolved. And it should dissolve on it's own after a few month from your body temp, but to speed up the process, boil some water, pour it in a bowl and breath in the steam for five mintues

This will help detox your lungs and after doing this several times, it has been 3 months and I do not feel any presence of the fibers.

Going to see a pulmonologist is going to run you hundreds and they cannot really do anything except percribe you an inhaler. X rays cannot detect it either.

But for sure get activated charcoal if it is in your throat, and do not be discouraged if nothing happens the first time arround. Use it multiple times

You can also go to a saunna to help detox the heavy metals out your body.

Hope this helps because I was trippin when it happened to me and cost me tons on medical bills and made me quit my job, but I'm solid now

I'm doing a bathroom renovation and removed some pink fibreglass from a section of the wall.  After doing some repairs at that section, I put the fibreglass back ( I cut 1-2 pieces as well).  
Unfortunately I didn't wear any protective gear.  I have no idea what I was thinking and now I'm a bit worried.  
If I've breathed in any fibreglass particles, do the lungs recover from this and remove the harmful substances?

I remodel basements and work with a lot of fiberglass insulation.  I am often caught in the midst of it without a mask and it will make my throat super sore for a few days (sometimes a full week).  But, you will wake up one day feeling fine.  Unless you're the first person in this thread, they sound like they have either Munchausen syndrome or a damn good insurance plan.

I moved into my house 2.5 years ago and recently just discovered that the HVAC return plenum has exposed fiberglass batting in it, so the air is being pulled right across the fibers whenever the HVAC runs. I just turned it off and will have it looked at and repaired (hopefully) tomorrow. Did your daughter recover from her symptoms completely after yours was repaired? Did she need any other treatment? I have a 1 year old baby and she gets an unexplained rash every now and then. I am not sure if I feel any symptoms or not, I have sensitive lungs anyway from previous pulmonary embolisms (prior to living here) and so it's hard for me to tell if I'm experiencing new symptoms or just still have scar tissue from PE. The fiberglass exposure breathing symptoms are very similar to PE symptoms. I'm just mostly concerned about my daughter's health and would like to know if your little one was healed. Of course, I'll call her pediatrician and explain the issue tomorrow and see if there's anything he wants to do. Thank you.

Poot615 ... Your symptoms are not caused by fibreglass insulation. Fiberglass's main issue is when extremely small fibers make their way into the deep lung tissue. Long-term exposure can result in silicosis. Short-term exposure is extremely unlikely to result in anything other than short-term irritation of the throat, nasal passages, in some cases nose bleeds, and a cough. Coughing will clean the lungs of much of the fibers. The extremely small fibers that make it to deep lung tissue will be slowly removed from the lungs via lung fluids then Microphages (supposedly). Usually in the case of long-term exposure, chronic conditions will not appear for at least around 20 years later. It is debated whether inhaling Fiberglass is  carcinogenic but we know that some industrial Fiberglass can be due to the binders used. They say that consumer household fiberglass insulation is not carcinogenic, but assuming it is, it would be estimated at about 7% of what asbestos is. So it's much better than asbestos in those terms, that's even if it is carcinogenic at all. Many people inhaled a lot of asbestos in their life and never even got any chronic illness, that being said obviously many also have. Acute Fiberglass exposure extremely likely will never lead to any long-term conditions what-so-ever. Long-term exposure could lead to silicosis/fiberosis over a period of ~20+ years due to scarring of lung tissue. Cancer is extremely unlikely in all cases unless you are working with specific industrial insulations, and even then, short-term exposure likely isn't much of a risk factor. If your house is contaminated, it's hell to fix (personal experience) but it needs to be done. Fix source of contamination first, then section by section hepa vacuum and wipe down with damp cloths, use an led light to inspect surfaces.

Ttoma, I was living in a house for 4 months that was completely contaminated with Fiberglass. My work also had me exposed daily for those 4 months. It has been 9 months since I quit there and for the first while I was coughing a fair bit. Some above average phlegm production as well but it seems to have gotten steadily better. I still have a cough and some phlegm, but at this point I'm not sure if Fiberglass has anything to do with it. Could just be a bit of a cold or regular phlegm production from other sources. No seemingly adverse health effect from the exposure remain. A lot of my stuff is still covered in it but I've been slowly going through the bins of stuff and cleaning it. The new place I am in has some exposed Fiberglass in the basement but I'm not really concerned. Fact is, the stuff is everywhere. I routinely visit people's houses and often there is exposed Fiberglass somewhere from work being done or unfinished basements etc. I even have family who build canoes and work with the stuff and when they visit I always find Fiberglass where ever they've been. The new place I work at has some exposed in a few places, including at the exit of some heat ducts from the furnace. Fiberglass is not healthy, but it's not a major hazard by a long stretch. Each case varies, but generally speaking the people who are at risk of serious adverse effects are those who work with it on a daily basis for many years, such as Fiberglass manufacturing, boatyards, and insulation installers. That being said, people tend to get very paranoid about Fiberglass, especially if you read everything people come up with online about it. Myself included, I absolutely hate the stuff and I get paranoid over it. It's not nearly as bad as some people claim, but it certainly isn't healthy. Do what you can to reduce exposure in your home and work place, but don't lose too much sleep over it

Not sure where you got this information but it is wrong! It is impossible for fiberglass to breakdown into styrene.  Fiberglass is  just that glass fibers and is inert and inorganic.  Styrene is an organic compound typically derived from petrochemicals or coal and is used to make polystyrene - (Styrofoam). It also occurs naturally in cinnamon, coffee beans and peanuts.  Inorganic compounds cannot breakdown or create organic compounds.

A quick Google search of how long it takes asbestos to dissolve in lungs will bring up many studies, including Fiberglass. Fiberglass with a diameter of 1micron or smaller will dissolve in the lungs in roughly 51 days. 3 microns and smaller are inhailable into the lung tissue. Therefore Fiberglass will dissolve and be removed from your lungs in a maximum of ~130ish days. Technically sooner thanks to Microphages. Most fibers are coughed out or caught in the throat/cilia and swallowed where they are removed quickly from the body. It is true that in the time the fibers are in the body, they can cause irritation and scarring, but the irritation is generally VERY short term and the scarring is only an issue in long-term repeated exposure or MASSIVE acute exposures. Even large acute exposures generally have full recoveries in 3-9 months. For you're a smoker, you're killing the cilia that protects your lungs and this will make all kinds of exposure much worse. cilia takes time to grow back after smoking, but it does. I'm not sure the time frame but in the majority of cases I would say well under a year.
As for Fiberglass and cancer... If it's special purpose fibers of diameter 3 microns or less AND 10 microns in length or more, it could cause cancer in the long-term. Usually 10-40 years after exposure, but usually only from long-term exposure. Also, less than 1% of all Fiberglass products contain what is designated as "special purpose fibers", none of which is household insulation. Of the TONS of Fiberglass in North America, over 99% is not "special purpose fibers". Certain ceramic-composite Fiberglass falls under being special purpose fibers and are used in extreme heat situations. Fiberglass that is not in the special purpose category does not have any risk of cancer from the fibers themselves, according to over 400 government and independent studies. You can argue there is lobbying, studies that are heavily-biased, or poor testing strategies but they're all quite conclusive in saying that Glass fibers are not carcinogens through inhaling. Implantation studies that do show cancer... Frankly aren't relevant. The original poster likely was suffering from issues brought on my something unrelated or exposure to another material/substance during the event. Or perhaps just has a personal agenda. One can easily google how Fiberglass and asbestos dissolve in lungs or the over 400 studies showing mostly the same results. I do agree that it would be nice to have more studies done unbiased and accurately on only particles that fit the description of being inhalable into deep lung tissues. Another point to make, Fiberglass breaks across the fiber and not length wise so it often breaks down to no longer be considered a fiber, unlike asbestos, and doesn't cause the avioli to close up and trap the fiber, which is why it is rapidly expelled from the system via coughing and mucus/phlegm production. To give some form of comparison, most asbestos fibers last 9-14 years in the lungs before dissolving, where Fiberglass can only last a max of 51 days (both in terms of a 1 micron diameter).

To go even further, for all of you who use cellulose insulations... A lot of dust inhaled from common household products, I believe cotton is one, and cellulose, actually persist in the lungs longer than Fiberglass when they make it to the deep lung tissues (where most serious issues can happen). Much like Fiberglass, they cause mechanical irritation and micro-inflammation. Although, again, they do not cause cancer. So, theoretically, they can cause more long-term issues in terms of scarring and fibrosis than Fiberglass can. Obviously dosage matters, especially when considering structure of the materials. Fiberglass is obviously more dangerous at the same dosages due to its physical structure, but being that cellulose and some constituents of all household dusts could last even longer in the body, you have to remember that we inhale much more of those products than we do Fiberglass.

Thankfully, your nose, throat, cilia, mucus, phlegm, coughing, lung fluids, Microphages, and the body's ability to remove foreign bodies or isolate them, and self-heal ultimately gives you a great line of defence. So stop being paranoid, take the proper steps to prevent unnecessary exposure, work safe, and live a happy life. Stress will kill you too, slowly and surely.

For those who want real scenarios, I have a family member that works building canoes and cuts, grinds, and sands Fiberglass daily. She is also a smoker. Yes, she wears proper protection while working. But she also brings a lot of it home with her in her vehicles, on her clothes, etc. She also lives in her basement which is full of exposed Fiberglass insulation. She has been doing this for 20 years. She has no issues with her lungs. I'm not saying it is good, it is definitely unhealthy but my point is, she's fine thus far and likely will never suffer anything serious from this. I grew up with exposed insulation in my basement in a number of places and played down there regularly and we had fans running etc, and I have absolutely no issues with my lungs. I even had a small asbestos exposure to tremolite (one of the worst asbestos forms) when I was 13. Still no issues. I've even had a recent chest X-ray. Lungs look perfect. I've also had a 4 month really bad exposure to Fiberglass, both at work and the house I lived in. Any symptoms I had quickly subsided. Fiberglass is unhealthy but it's not radioactive. Fiberglass, in today's age, is a fact of life and is not a serious hazard. Those who need to be concerned are those who work with it daily. Now stop reading all the insane amount of paranoia the Internet is spewing at you and do something productive or enjoyable. If you've got a Fiberglass issue, get it fixed but don't lose sleep over it. Trust me, I've been there.
