InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers, products, or services discussed at this website. This document assists building buyers, owners or inspectors who need to identify asbestos materials or probable-asbestos in buildings by simple visual inspection. We provide photographs of asbestos containing materials and descriptive text of asbestos insulation and other asbestos-containing products to permit identification of definite, probable, or possible asbestos materials in buildings. Asbestos is safe and legal to remain in homes or public buildings as long as the asbestos materials are in good condition and the asbestos can not be released into the air. Here we provide a master list of manufactured products that contain asbestos.VIDEO ON THE TOPIC: Learning the Basics of Fibreglass Laminating Video

This article series provides information about how to identify fiberglass insulation in buildings and fiberglass hazards and fiberglass insulation contamination issues in residential and light-commercial buildings. The fiberglass research literature is replete with studies indicating that there are no health hazards associated with airborne fiberglass particles, and with other studies reaching quite the opposite conclusion.
We recommend that readers examine carefully the methodology used in such studies, the expertise of the researchers, and the sources financing of such work. What are the Problems with Identifying Fiberglass Hazards in buildings?
Microscopic identification of fiberglass insulation fragments,. Fiberglass exposure hazard reference list, Fiberglass insulation demolition mess, itching, dust persistence.
Based on literature review as well as both field and laboratory experience, it is reasonable to claim that large particles of fiberglass are far more likely to be a respiratory or skin irritant than a carcinogen or other more serious health hazard. However some of our field and lab inspections detect very small, even sub-micron sized particles which are traced to building insulation. These much smaller particles may indeed be a health hazard, and may be entirely omitted or simply missed by some laboratories charged with reporting on the level of fiberglass in building air or dust.
In field and laboratory experience with dust collection and characterization we have found that small particles in the PM1 or smaller range are most-often not looked-for and not reported. It is possible that by failing to screen for and detect any particle during environmental testing or health studies, the effects of those particles are under-stated or missed entirely. This article explains the recognition of types of fiberglass insulation in buildings, other fiberglass particle sources, and some possible health concerns that involve these materials.
Fiberglass building insulation is commonly installed in batts or chopped forms and may be yellow, pink, green, or white in color as is shown in these photographs. While this material is not and should not be confused with asbestos nor with the well-studied health hazards associated with exposure to asbestos fibers or dust, our separate article on Airborne Fiberglass Building Insulation Hazards [link just below] and HVAC duct work insulation hazards contains additional discussion about possible air quality and health concerns which may be associated with exposure to fiberglass dust.
Fiberglass duct insulation material appears in several forms in heating and air conditioning systems in both ducts and air handlers themselves. The most common uses of fiberglass insulating material in HVAC systems includes the cases listed below. The annotated duct system photographs shown in the article cited below will permit any careful observer to identify the most common types of fiberglass HVAC duct materials.
We provide these C -protected photographs of fiberglass insulated ducts and HVAC components to aid in recognition of these materials. Our detailed article on how to recognize fiberglass duct insulation and its characteristics and hazards can be read in its entirety. Special challenges face consumers requesting lab services for identification of fiberglass fragments in air, dust, or material samples are easily identified in the forensic laboratory using light and polarized light microscopy and common slide preparation techniques.
Our photograph left shows a typical fiberglass insulation fiber with droplets of resin binder attached. It's easy to identify large fiberglass fibers in transmitted-light microscopy. But identification of very small fiberglass fragments in a building dust or air sample can be difficult to detect unless the microscopist is trained and looking for that material, and special methods such as use of phase contrast may be needed.
Observing the color of a fiberglass bonding resin can help trace particular fiberglass in a building air or dust sample back to its source. Other fiberglass products, such as this Certainteed un bonded blowing wool fiberglass lack a characteristic resin. Interestingly in this client-provided sample of nearly-new blown-in fiberglass insulation we found very few small fiber fragments.
Dust tested from that home was also low in fiberglass fragments. The common errors which result in failing to detect small fiberglass particles in building air and dust are discussed in detail.
In that article we also discuss techniques which permit the forensic microscopy lab to identify the source or reservoir of particular fiberglass fragments in a building, sorting out among many possible fiber sources to pinpoint the particular problem such as damaged building insulation, damaged HVAC duct work, or other particle sources. We also discuss how to distinguish among types of insulating and other fibers, comparing various types of fiberglass insulation, mineral wool insulation, asbestos insulation, and other fibers.
Frequent presence of fiberglass fragments in air and some dust samples, suggests that an HVAC duct system or exposed fiberglass insulation in the building may be contributing unwanted and potentially unsafe levels of these fibers.
This discussion can be read in its entirety. We have also detected high levels of problematic mold in fiberglass building insulation where other mold reservoirs were either not present or had been previously removed. I have a question regarding fiberglass insulation. I pest control worker, who is trying to rid us of rats in the attic, removed the fiberglass insulation from the attic space but dragged the insulation through the house.
Now, we are constantly itching. Is is due to fiberglass particles in the air? What can we do? We've vacuumed a lot but it's not helping.
A competent onsite inspection by an expert usually finds additional clues that help accurately diagnose a problem such as incomplete cleaning, or some other problem source yet unnoticed, including a biological hazard associated with the rodents themselves.
In addition to consulting your doctor who may in turn decide to refer you to a dermatologist, you might also benefit from reviewing. That said, here are some things to consider about itching after messing with fiberglass insulation:. Dragging fiberglass through a building is likely to have left a fair amount of broken fiberglass fragments on floors and through air transport, as settled dust on surfaces.
If you haven't done so you may want to clean the rooms through which insulation was dragged using damp wiping and then HEPA vacuuming of all surfaces, especially floors, carpets and any nearby furniture, shelving, etc. It can take two or in a few cases even three trips through the washing machine to remove enough fine insulation fragments from clothing that it would not any longer be irritating to your skin.
In my experience, working with insulation, especially during demolition when lots of material is broken up and airborne, the skin itching can last for a day or two after the work has been completed. Taking a couple of showers, washing fully, may remove the dust, debris, and fiber fragments, or nearly all of them, from your person, but the skin may have become irritated, taking a bit longer to recover. If itching continues after you've cleaned yourself, clothing, and any dust left in the building use a HEPA vacuum when vacuuming up fine dust , then I suggest checking with your doctor or a dermatologist.
If you have reason to suspect that there remains irritating dust and an irritating dust source in the building, I'd consider collecting one or two tape samples of settled dust from a horizontal surface in an area where you spend the most time and in an area where you think the dust is worst. Have those samples analyzed to identify the dominant particles - as that may be diagnostic. You shouldn't need many samples, perhaps two or at most two plus a control.
A settled dust collection procedure for collecting a dust sample that should be just fine is found. Please do not send us your sample. I want to avoid even the appearance of any conflict of interest. Should I be concerned about exposed insulation in my basement? And, when they're talking about special-purpose fiberglass being a carcinogen, what makes it "special purpose" and what products fall into that? Thanks in advance, I'm having some fiberglass contamination issues and trying to learn what I can.
Having examined many indoor dust and air samples, I intended to say that I will almost always find at least some fiberglass fragments in most buildings. However the number of such particles will not normally be significant - certainly it's not the dominant particle. In such an environment it might be significant, depending on what work is being done and how dust control is being managed.
I'd be more concerned about very small fiberglass fragments in the 1u range that may be released by grinding or sanding. So how concerned should I be There is enough in my vehicle that I can easily see dozens of fibers, hundreds, when I shine a light. My work has no dust collection system, only gloves, apron, and respirators. We also cut Kevlar, but I'm only really concerned with the fiberglass. I cannot assess nor even guess at actual airborne particle level exposures from an e-text.
Certainly there are OSHA regulations about dust control in the workplace. OPINION: Notice that there are no exposure standards for ultra-small fiberglass fragments, possibly because the exposure guideline writers focused on intact, un-damaged fiberglass substances in normal use and exposure. Synthetic mineral fibers are fibrous inorganic substances made primarily from rock, clay, slag, or glass. These fibers are classified into three general groups: fiberglass glass wool and glass filament , mineral wool rock wool and slag wool , and refractory ceramic fibers RCF.
There are more than , workers in the US exposed to synthetic mineral fibers in manufacturing and end-use applications. Workers have a right to a safe workplace.
The law requires employers to provide their employees with safe and healthful workplaces. The OSHA law also prohibits employers from retaliating against employees for exercising their rights under the law including the right to raise a health and safety concern or report an injury.
For more information see www. OSHA can help answer questions or concerns from employers and workers. Workers may file a complaint to have OSHA inspect their workplace if they believe that their employer is not following OSHA standards or that there are serious hazards. Your contact will be kept confidential. We can help. And see the article above where I explain that most likely the more serious hazards are with the smaller particles. An individual can also protect himself with respirator and proper clothing.
Char said: Thank you for your reply. However, I am Canadian so those phone numbers and contact information doesn't apply to me. Is there something similar for Canadians?
I'm assuming there would be. Sorry for the presumption. The US OSHA general advice about fiberglass hazards should be valid world-wide but of course none of the phone numbers make sense for you. Canadians are less fearful of fiberglass than some Yanks. The Health Canada discussion of workplace IAQ mentions mold and general hazards and housekeeping see.

Fibre-reinforced plastic FRP also called fiber-reinforced polymer , or fiber-reinforced plastic is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass in fibreglass , carbon in carbon fiber reinforced polymer , aramid , or basalt. Rarely, other fibres such as paper, wood, or asbestos have been used. The polymer is usually an epoxy , vinyl ester , or polyester thermosetting plastic , though phenol formaldehyde resins are still in use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries.

Очевидно, она перевела свое имя на единственный язык, равно доступный ей и ее клиенту, - английский. Возбужденный, Беккер ускорил шаги в поисках телефона.
По другой стороне улицы, оставаясь невидимым, шел человек в очках в тонкой металлической оправе. ГЛАВА 27 Тени в зале шифровалки начали удлиняться и терять четкость. Автоматическое освещение постепенно становилось ярче.
Всякий раз включался автоответчик, но Дэвид молчал.
И мы нашими совместными усилиями даже близко не подошли к математической функции меняющегося открытого текста. А вы хотите сказать, что какой-то панк с персональным компьютером придумал, как это сделать. Стратмор заговорил тише, явно желая ее успокоить: - Я бы не назвал этого парня панком. Но Сьюзан его не слушала.
Северная Дакота - призрак, сказала она. Сплошная мистификация. Блестящий замысел. Выходит, Стратмор был зрителем теннисного матча, следящим за мячом лишь на одной половине корта.SEE VIDEO BY TOPIC: Asbestos Fibres - How your lungs are effected - Asian Ban Asbestos Video,English
Наконец раздались длинные гудки. Ну давай. Окажись дома. Через пять гудков он услышал ее голос. - Здравствуйте, Это Сьюзан Флетчер.
Она завершила ввод данных и запустила Следопыта. Затем щелкнула по кнопке возврат. Компьютер однократно пискнул. На экране высветилось: СЛЕДОПЫТ ОТПРАВЛЕН Теперь надо ждать. Сьюзан вздохнула. Она чувствовала себя виноватой из-за того, что так резко говорила с коммандером. Ведь если кто и может справиться с возникшей опасностью, да еще без посторонней помощи, так это Тревор Стратмор.
- Она давно уехала. Отправилась в аэропорт несколько часов. Самое место, где толкнуть колечко: богатые туристы и все такое прочее. Как только получит денежки, так и улетит.
Но система безопасности АНБ была лучшей в мире. Никому даже близко не удалось подойти к базе АНБ, и у агентства не было оснований полагать, что это когда-нибудь случится в будущем.

Хейл достаточно понимал язык программирования Лимбо, чтобы знать, что он очень похож на языки Си и Паскаль, которые были его стихией. Убедившись еще раз, что Сьюзан и Стратмор продолжают разговаривать, Хейл начал импровизировать.
