Remove Asbestos Flooring Adhesive

asbestos adhesive
Asbestos adhesive was used for asphalt flooring tiles and vinyl or linoleum sheet tile because it strengthened the flooring and made it more durable. It was also resistant to moisture, oil grease heat alkalis and acids. But then asbestos was found to be a health hazard. Newly laid floors with asbestos adhesives are not hazardous, but as water and/or weathering weakens the floors the asbestos crumbles and fibers are released in the air. Inhalation of asbestos fibers can cause mesathelioma cancer, and environmental experts and health professionals warn against the usage of asbestos adhesives for flooring.

How to Remove Asbestos Flooring Adhesive

Prepare the floor for removing asbestos adhesive. Switch off all heating and air-conditioning appliances that will aid air circulation. Cover all vents and openings with polythene sheets and secure with duct tape. Seal all small ducts fissures or openings with duct tape. Cover doorways with polythene sheeting. Experts recommend that the floor should be flooded with warm water for two days for optimum effects. This is because wet asbestos adhesive will not release unhealthy fibers into the air. If a two-day flooding is difficult a 30 minute flooding will do the job.

Wear a disposable work suit, gloves, boots, and eye protection. Also, be armed with heavy-duty polythene bags and duct tape and tools will help keep you safe from inhaling asbestos fibers. Take the mop, disposal towels, chemical solvent and scraper with you for the job. Check with the manufacturer if the chemical solvent you plan on using will work on asbestos adhesive. The chemical solvent should not be abrasive because any abrasive action will throw asbestos fibers into the air.

Apply the chemical solvent or amended water gently as required to the asbestos adhesive. Gentle rubbing with disposable towels or mopping should easily clean away the wet adhesive. Stubborn spots should be removed with gentle scraping. Do not grind or sand the adhesive because these actions release the asbestos fibers into the air.

Clean up and dispose of the asbestos. Cleaning up is the most important and difficult part in removing asbestos adhesive from the floor. Wipe all surfaces with a damp disposable towel. Rinse the cloth or towel and change the water at least twice. Wipe all the polythene sheeting where asbestos fibers could have settled. Put all the polythene sheets in heavy-duty waste bags and seal them with duct tape. Put the mop heads and disposable towels in disposable bags and seal them with tape. Inspect all surfaces for dust and wipe with damp disposable towel to get rid of any asbestos fiber deposit. Wash all the tools thoroughly. Wash any exposed skin thoroughly.

Clean and put disposable work suit in waste bag and seal. Wipe all other clothing with damp towel put all used towels in waste bag and seal. Take a shower to remove any possible fiber on your body.

Dispose of all waste. Disposing of the waste bags is the final part of removing asbestos flooring adhesives. The local EPA office will guide you about disposing the waste bags. You can either dispose of them at landfills that accept asbestos waste or you can inform your local waste hauler for a special waste pickup. There are also licensed contractors who will take asbestos waste for disposal.

Asbestos ceiling tiles

Asbestos ceiling tiles
Asbestos ceiling tiles were commonly used in homes and buildings before the 1970s. Asbestos is a fiber that was once used in "acoustic" ceilings which were also called "drop" or "suspended" ceilings. Before the carcinogenic affects of asbestos were known; many people were unfortunately exposed to these fibers since they were often used in numerous different materials including roofing and ceiling products.

Asbestos is only dangerous if the material is airborne; therefore, contaminated ceiling tiles are only harmful if damaged. If you would like to remove these tiles from your ceiling, it is best to have a licensed contractor complete the job for you. If you decide to remove the tiles yourself, you will need to proceed with extreme care and caution.

How to remove asbestos ceiling tiles

  1. To remove asbestos ceiling tiles, you will first need to dress properly. Wear a tyvek suit, safety glasses, and an approved respirator. This protective clothing can be purchased either online or at a local store. You don't want any asbestos contaminated materials to get on your skin, in your eyes, or into your lungs. 
  2. Turn off any heating and air circulation systems to avoid the chances of any asbestos in the ceiling tiles from becoming airborne. 
  3. Place a tarp directly underneath where you will be working and set up a ladder. 
  4. Add 2 teaspoons of dishwasher detergent to 1 gallon of water. Pour some of this mixture into a spray bottle and start by spraying one of the asbestos ceiling tiles with this detergent water. This will help to keep the fibers from becoming airborne if you were to break any of the tiles. 
  5. Carefully remove the ceiling tiles one by one. You will need to avoid breaking or tearing the tile since this can cause the asbestos to become airborne. As you remove each tile, place them directly into a yellow asbestos bag. Once the bag is full of tiles, seal it completely with duct tape and then place it into a 6 mil polyethylene bag. 
  6. Once you've finished removing the tiles, place the tarp from under your project into one of the asbestos bags to be disposed of. 
  7. Properly dispose of the asbestos ceiling tiles by following the regulations set by your state.

Seal The Asbestos Tiles

Asbestos Tiles
If you have an older home, your old tile flooring may contain asbestos. Asbestos is a tough, durable fiber known to cause a variety of respiratory ailments and diseases such as cancer. Floor remodeling jobs in the home may require a professional asbestos removal company if the asbestos-based tile is chipped, crumbling or otherwise damaged. However, if it is intact, you can seal the tiles yourself to prevent future asbestos exposure. After sealing the asbestos tiles, you can install a new floor on top of the old one.

How to Seal Asbestos Tiles


  1. Use the hammer and pry bar to remove the baseboards along the floor in the area that has the asbestos tile. Pry the baseboards away from the wall gently to prevent splintering so you can use them again. Removing the boards allows better application of the embossing leveler. 
  2.  Prepare the asbestos tile flooring by wet mopping it to ensure all dirt and debris is removed. If there are any oily areas, use a degreasing cleanser on the floor then rinse with water. Allow the floor to dry slightly, until just moist to the touch. 
  3. Mix the embossing leveler (purchased at most paint, flooring or hardware stores) with water, according to manufacturer's instructions in one of the large buckets. Use the wood paint stirrer stick to mix the leveler compound to a smooth consistency. 
  4. Fill remaining bucket with water. This water bucket will serve as a rinsing receptacle for the metal trowel during the leveler compound application process. 
  5. Pour the mixed embossing leveler compound on the asbestos tile flooring. 
  6. Use the metal trowel to smooth the leveler compound across the asbestos floor tile. You have a short amount of time to work with the embossing leveler before it starts to set or cure, so trowel quickly. You want this underlayment to form a thin, level layer over the tile, creating a sealed surface in which no asbestos fibers can escape. 
  7. Rinse the metal trowel in the water bucket every few minutes to prevent a buildup of the leveler compound on the metal surface 
  8. Allow the embossing leveler compound to dry for at least two hours. Check manufacturer's instructions for more approximate drying times. During the drying process, do not walk on the floor surface. Once cured, you can use the hammer to re-install the base boards.

How to Diagnose Asbestos Poisoning


A number of people exhibit symptoms of asbestos poisoning or its deadly cousin, mesothelioma, after years of working in manufacturing jobs or careers dealing with various forms of friable asbestos. Although it is a natural mineral fiber, breathing in the tiny particles from asbestos dust results in the fibers adhering to the lining of the lungs and greatly increases the risk of lung disease and cancer. Mesothelioma is the name given to malignant cancers started by asbestos poisoning,


Instructions

Search your job history for repeated exposure to friable asbestos. For asbestos to be a poison, it must be in a breathable form. Friable asbestos easily crumbles and the tiny featherweight particles quickly disperse in the air. Some examples of friable asbestos are blown-in insulation around pipes, acoustical ceiling panels and wallboard and joint compound manufactured before 1978. Although now banned in this form, many homes still contain this dangerous textile.
Compare your symptoms to your work history if you suffered exposure to friable insulation on an ongoing basis. Keep in mind that you may not suffer the ill side effects for many years.
Consider asbestos disease as an explanation for medical symptoms that include difficulty drawing a full breath or exhaling fully, along with a chronic cough. This is a common first symptom of asbestos poisoning but since it also mimics many other respiratory diseases, it may go undiagnosed until other symptoms appear.
Pay attention if others mention that you sound a little hoarse. In the early stages the hoarseness may come and go but it will gradually worsen if the cause is asbestos poisoning.
Suspect asbestos poisoning if the above symptoms appear within 20 years of prolonged exposure to friable asbestos and medications for respiratory infections and flu symptoms have not cleared up the problem. In addition, coughing up blood, weight loss or chest pain, suggests the asbestos disease may have developed into mesothelioma.
Schedule an appointment with a physician who is familiar with testing for asbestos poisoning and the cancers related to the disease. The doctor will record your work history and will order pulmonary function tests as well as chest x-rays. If he suspects an asbestos disease or mesothelioma, he will likely order a Computerized Tomography Scan (CT scan) to make an accurate diagnosis.

Renovating Your Home For Asbestos

Older homes are known for being full of personality as well as good memories. If you choose to live in an older home, it can be a great investment. However, one problem with older houses is that they may have been built using asbestos-containing products. If you suspect that your home contains asbestos, it is very important to renovate your home to remove the toxin while still keeping you and your loved ones safe in the process.
First, it is important to know where asbestos might be present in your home. Asbestos became very popular during the Industrial Revolution because of its insulating properties. As a member of the silicate mineral property, asbestos is resistant to heat, flame, chemicals, electricity, and biodegradation. Additionally, asbestos itself has the useful characteristics of high tensile strength and flexibility, which means that it is easily added to a variety of different materials.
Thus, the construction industry embraced asbestos. For a time, it was added to vinyl flooring, insulation, ceiling tiles, roof tiles, and roofing tar, among many other things. Therefore, it could be present virtually all around you. If you suspect that there is asbestos in your home, you should call a certified asbestos inspector. Don't try to examine the substance yourself, as you may expose yourself to the carcinogen.
Asbestos can be divided into two categories, friable and non-friable. Friable asbestos is able to flake into microscopic particles, and non-friable asbestos cannot. Asbestos is only dangerous when it is in the friable form. This type of asbestos is able to become airborne, where you can ingest or inhale it. Once the fibers are in your body, they can become lodged in your tissues. Your body is unable to break down and process asbestos, so it often makes nodules around the fibers. These can contribute to scarring or the nodules can turn into cancerous tumors.
If there is indeed asbestos in your home, professional asbestos renovators have several options to protect you and your loved ones. If the asbestos is friable, they can either remove it, or paint special lacquers over the material to block the release of the fibers. During this process, the renovators must have special ventilating units in place so that the airborne particles are not spread throughout your home.
When you inhale asbestos fibers, it can cause lung cancer and mesothelioma. If you or someone you love has developed mesothelioma as a result of asbestos exposure

Friable Asbestos: The Real Culprit Behind Your Symptoms

In any discussion concerning asbestos and the physical symptoms that can be developed from it we need to understand what is mean't by the term friable. Asbestos is said to be "friable" when it is dry it can be crushed or pulverized thus reducing the mineral into a powderized state. The real danger that occurs when asbestos is crushed is that it can easily become air born. Once the tiny fibers of asbestos are air born they can be inhaled into the lungs and once in the lungs the whole chain of events begins to unfold which can lead to scarring, asbestosis and even mesothelioma.
What are some examples of friable asbestos?
Some common examples of friable asbestos products would be acoustic ceiling tiles, many types of plaster and wall board, sprayed on insulation on boilder pipes, insulation inside of boilers, insulation inside of hotwater heaters and many more. These items can all be pulverized and reduced to a powder that can easily become air born. A good example of non-friable asbestos would be vinyl floor tiles and asbestos siding and some shingles. Floor tiling is a product that often contains asbestos but as long as it is not sawn, ground or sanded it remains incapsulated and consequently remains non-friable.
What should I do if I encounter a material that I suspect may contain friable asbestos?
The first thing that you should do if you suspect the presence of asbestos is to have a sample of the product tested at an EPA approved asbestos lab. Once you have sent in your sample and it has been found to contain asbestos you should then use this same site to locate a professional asbestos abatement company. This is no job for the unlearned or naive. Once a material is determined to be friable it is labeled as regulated asbestos containing material (RACM). The safest way to deal with it is to let the professionals handle the removal. The cost of inhaling friable asbestos fibers is too high to take chances with your health. It is worth a little extra money to avoid serious asbestos symptoms.

asbestos poisoning

Before we discuss the term 'asbestos poisoning', let's have a look at some basics surrounding the material itself. Asbestos is a fibrous mineral that is found in nature. It has been used liberally and widely in buildings and other constructions for over 100 years. The fibers of asbestos are durable and sturdy, yet, flexible and extremely resistant to heat. Asbestos can be found in a broad variety of products, such as flooring and ceiling tiles, house siding, roof shingles, pipe insulations, etc. To give you some numbers: a study that was conducted not too long ago, indicated that in the Unites States alone, asbestos has been used an estimated 30 million tons and can be found in over 3,000 products in industries like automotive, textile, electronics and construction.

However, the material was proven to be dangerous since a clear link between asbestos exposure and severe health effects was established. When we talk about asbestos poisoning, we refer to any illness or injury that was caused by the exposure to asbestos. It is important to note that if asbestos remains unhampered and undisturbed, no health risk is imminent. Asbestos is friable which means that it can be broken up under only a fairly small amount of pressure. As a result, the minerals separate into microscopically small dust particles. As these particles get airborne, they may be inhaled by anyone onsite or in close proximity, which can cause a number of severe health conditions, such as mesothelioma, lung cancer and asbestosis. A high risk of asbestos poisoning is posed to people with occupational exposure to the hazardous material.

In the early 1900s, researchers and the medical community reported an emerging trend of newly diagnosed patients and fatalities in workers holding jobs in asbestos mines and the asbestos manufacturing industries. Because of the long latency time of asbestos induced diseases, it took another few decades until the problem manifested itself in its entirety. Thousands of people got diagnosed and often died within a matter of months thereafter.

Asbestosis is comparable to an inflammation. It occurs when asbestos fibers are ingested or inhaled and get trapped inside the lungs. As the body's own defense mechanism kicks in, an acidy substance is being produced with the objective to dissolve the fibers. However, the acid does unfortunately have no impact on the asbestos, but directly affects the lung tissue which over course of time, results in scarring. The scarring impairs the regular functionality of the lungs.

Mesothelioma is cancerous and fatal. It is the only illness that is solely linked to asbestos exposure. Lung cancer is ranked number one worldwide among the most lethal cancers. Smokers who are exposed to asbestos are at a significantly increased risk of developing the disease.

Three Deadly Diseases That Affect Asbestos Plant Workers

By the term asbestos, we refer to all those fibrous minerals that are used as an element to resist heat or fire. Asbestos is dug from rocks that are metamorphic in nature. Asbestos plant workers are employed for the purpose of digging asbestos from the rocks. This has put most of the workers in this profession at risk because they are in contact with asbestos. When exposed to asbestos, people can suffer from various diseases such as lung cancer, mesothelioma, asbestosis, pleural plagues, etc. These asbestos related diseases are on the rise particularly in countries like the United States.

These ailments caused by exposure to asbestos are deadly because till date there has been no cure for most of these diseases. So it is very important for asbestos plant workers to be careful when they are working in an environment that has asbestos. They have to take extra precautions so that they do not breathe in the asbestos fibers.

In the early days, people in Greece noticed the harmful effects of asbestos on people working with asbestos to turn it into cloth. In recent times, the death tolls started to rise in those places where asbestos mines were situated and this made people investigate the properties of asbestos.

Those companies that were engaged in producing goods from asbestos decided to overlook the harmful effects of asbestos and as a result, the asbestos plant workers became prone to asbestos related diseases. Several lawsuits have been made against the asbestos companies because of the adverse effects of asbestos on the plant workers.

Some Diseases Affecting The Plant Workers

The diseases that affect the asbestos plant workers are as follows:

Asbestosis

When the plant workers inhale or take in asbestos fibers, they are putting themselves at risk of getting asbestosis. After inhaling the asbestos fibers, the worker's lung suffers from inflammation and irritation. This disease is not cancerous which means that it does not lead to cancer. Initially, the body of the worker tries to protect it self by fighting with these fibers but this will further make the matter worse by harming the cell and causing inflammation.

The worker may not know that he has asbestosis because this is only discovered though x-ray. He will not feel or experience any symptoms, which will make him come to a conclusion that he might be suffering from asbestosis. The airways and the air sacs of the worker's lung may be blocked by scar tissues or fibrosis that grows near these air passages. This will make the worker feel uncomfortable while breathing. In fact, the more the scar tissues or fibrosis grow the more complicated it will be for the worker to breathe properly. When an asbestos plant worker has asbestosis, he will cough and will not be able to breathe normally.

These symptoms will deteriorate with time even when the worker is not being exposed to asbestos anymore because this disease is progressive in nature. Even though it is rare but some times this disease can be deadly. Such an ailment can harm both the lungs of the worker. It means that it is not restricted to one lung only. Those who are suffering from this disease are more prone to develop mesothelioma or lung cancer. Currently, no cure has been found for this kind of disease and this is one of the reasons why all the plants' workers are asked to be very careful while they are at work.

Mesothelioma

Mesothelioma or malignant mesothelioma is a disease where tumor develops in the body of the asbestos plant workers when they are exposed to asbestos fibers. This tumor has the propensity to extend or multiply to various body parts and hence, this disease is considered to be fatal. Mesothelioma either develops in the abdomen or chest cavity. There are also cases where the tumor grows in the cavity close to the heart. Studies have shown that men workers are more prone to develop this disease as compared to women. Research has also shown that Mesothelioma is more common among the Caucasians. Actually, this type of disease is not common but once it attacks a person it can be very risky.

Lung cancer

This disease is regarded as one of the most deadly diseases where the tissue in the lung is transformed and expanded. Exposure to asbestos can lead to lung cancer in the asbestos plant workers.

A Guide To Asbestos In The Workplace

Asbestos is a natural mineral with its primary use in fire proofing and insulation. There are three key types of asbestos:
  • Amosite (also called grunerite or brown asbestos);
  • Chrysotile (also called serpentine or white asbestos);
  • Crocidolite (also called riebeckite or blue asbestos).
However, it is not always possible to identify them by colour alone.

Why is it hazardous to health?

Asbestos-related diseases are responsible for over 3,000 deaths per year in the UK. The delays between first exposure to asbestos and the onset of disease are usually long, and can be between 15 and 60 years. Moving or disturbing asbestos can release small fibres of asbestos into the air, and inhaling these fibres can be the cause of fatal diseases. The tiny fibres can be breathed into the lower parts of the lung and could work their way through the lung lining, potentially causing:
  • Asbestosis or fibrosis (scarring) of the lungs;
  • Mesothelioma (a cancer of the inner lining of the chest wall or abdominal cavities);
  • Lung cancer
What are the legislative requirements concerning asbestos in the workplace?

The revised Control of Asbestos Regulations 2006 (CAR) came into effect on 13 November 2006. The regulations were introduced to strengthen overall staff protection by clearly outline limits for exposure. Training for those who manage, or work directly with, asbestos has also been made mandatory.

What guidance is available in the UK?

To make people more aware of the duty to manage, and the promotion of effective compliance, there is guidance available from the HSE. An Approved Code of Practice (ACoP) to support Regulation 4 of CAR. "The management of asbestos in non-domestic premises" (L127) (revised) gives in-depth advice on how to meet compliance under the new requirements. A guidance booklet, "A comprehensive guide to managing asbestos" (HSG227) is aimed at duty holders within larger, more complex organisations. A free leaflet, "A short guide to managing asbestos in premises" is aimed at duty holders in smaller, less complex premises. HSG264 "Asbestos: The Survey Guide - a guide for surveyors and Duty Holders." This guide superseded MDHS100 in 2009 and provides a clear picture for both duty-holders and surveyors with regard to the surveys role in effective management of asbestos.

The duty to manage requires those in control of buildings to, take reasonable measures to find evidence of asbestos in the building and assess the material's condition. Make the assumption that materials contain asbestos, unless there is strong evidence to the contrary. Record the location and condition of all asbestos containing materials (ACMs) and assess the associated risks. Prepare and implement a plan to manage the above risks. Provide a report detailing the location of the materials and their condition to anyone who is likely to work on or disturb the materials.

Asbestos management consultancies should supply the following to you:
  • A review of your current management looking at all aspects of the management of asbestos and a detailed action plan for your compliance.
  • An asbestos survey to give you an understanding of where you have asbestos in your premises, if at all.
  • An Asbestos Management System so you are able to effectively manage the requirements of all asbestos regulations and to give you comprehensive information about any asbestos you have in your building.
  • Condition assessments so that asbestos-containing materials (ACMs) are regularly checked for condition
  • Asbestos training for personnel at all levels, from the identification of asbestos containing materials (ACMs) to the management of asbestos in your building.
It is crucial to keep in mind that the CAR regulations state that you have a duty to manage, and not merely to survey.
