How to reduce/limit your exposure to asbestos fibers? Asbestos flooring has asbestos fibers that can cause various health problems if inhaled, so never do anything that can crack, break, disturb or damage the tiles, which may cause the fibers to become airborne.

  • Generally health problems only occur in people who have had lots of contact with asbestos over a long period of time due to occupational exposure, but safety is always important and it’s better not to risk anyone’s health.
  • If tiles are damaged or cracked, take care in removing them & dispose of them as hazardous material per local & state regulations.

Properly encapsulating or sealing asbestos tiles will help greatly in preventing the asbestos from becoming airborne as the process of encapsulating or sealing will bind the fibers together. As long as the tiles are intact, there’s no health danger.

What can I cover a asbestos roof with?

Budget: Is coating cheaper than over cladding asbestos roofing? – Coating has traditionally been the cheaper method of waterproofing an asbestos roof. Fluctuating steel prices can make over-cladding vary in cost, steel being the favoured material used in over cladding.

  1. As for how this will exactly affect the price differential between the two systems, no one can know for sure at this time.
  2. Of course, it’s not only about the price of the product.
  3. Both solutions need access to the roof via cherry pickers and scaffolding, adding labour and hire costs to the bill.
  4. But this is where coating clearly trumps over cladding.

Coating a roof can be quicker and easier, meaning on site time is reduced and scaffolding isn’t required for as long. There’s also extra construction costs involved in over cladding, such as meeting current regulations for insulation, and ensuring the building structure is strong enough to support another roof.

Can I drink water from an asbestos roof?

Asbestos in Drinking Water a Problem in U.S. and Canada – The National Water Quality Management Strategy for Australian Water Guidelines, released August 2018, is hardly reassuring. Studies in the United States and Canada have reported typical asbestos fiber numbers in drinking water of less than 1 MFL (million fibers per liter).

  • Severe deterioration of asbestos cement pipes has been known to produce fiber numbers of up to 2,000 MFL.
  • Australian drinking water supplies have not been routinely monitored for asbestos.
  • However, fiber numbers are probably similar to those reported overseas.
  • These numbers can be reduced by the standard water treatment processes of coagulation and filtration.

Unfortunately, there is nothing we can do about the drinking water that comes through our taps, but there is something we can do to protect our health when capturing rain water in our backyard water tanks. If the water has flowed across areas of the roof that have previously become friable, it may contain deadly asbestos fibers. Free Mesothelioma Guide Get Answers to All Your Mesothelioma Questions

What happens if you have asbestos in your roof?

The Health Risk of Asbestos – The HSE are currently running a ‘Beware Asbestos’ campaign until March with the aim to encourage safe working practices amongst workers most at risk from asbestos. Statistics show that Asbestos kills around 5000 workers each year, whilst 20 tradesmen die each week as a result of past exposure 10,

  1. These are harrowing figures which prove that asbestos is still a very real and very genuine threat, not only exclusively to tradesmen and those working with its removal; but also for those who work in the building and other people in the surrounding areas.
  2. The risks occur when damage, fire or disturbance to the products cause the asbestos fibres to become loose and potentially airborne.

When these tiny fibres are inhaled they do not decompose and remain permanently lodged in the lungs which can lead to fatal diseases as the body attempts to fight these alien fragments. Initially it will cause soreness, inflammation and infection which can lead to any of the following diseases:

Mesothelioma Lung Cancer Asbestosis Pleural Thickening

For further information on any of these conditions or diseases, please visit the NHS website or contact them. If you have any concerns that you may have been exposed to asbestos at any point then contact your GP for further advice. A Combined Killer – There is undisputed evidence that people who are exposed to asbestos and are smokers have a dramatically increased chance of contracting lung cancer, with the smoking acting as a catalyst for the development of the cancer.

Does asbestos melt in water?

Asbestos fibres – Asbestos fibres are strong, heat resistant and have insulating properties. Clumps of mined asbestos can be broken down to loose fibres or fibre bundles, and mixed with other materials, such as cement, to produce a variety of building products.

  • Up to 90% of the asbestos produced in or imported into Australia was used for the manufacture of building products, especially asbestos cement materials.
  • Asbestos fibres are not visible to the naked eye.
  • They can become airborne from the breakdown of natural asbestos deposits and manufactured asbestos products.

Once airborne, small fibres may remain suspended in the air for a long time and can be carried long distances by wind before settling down. Large fibres and particles tend to settle more quickly. Asbestos fibres do not dissolve in water or move through soil.

Does water dissolve asbestos?

Overview Asbestos is a commercial and legal term referring to a class of minerals that naturally form long, thin, very strong fibers. Asbestos has been mined and used in many products worldwide, mostly during the 20 th century. In the United States, mining asbestos has ended, but asbestos is still present in older homes and buildings, and some products still contain it. Asbestos Hazards Disturbing asbestos minerals or other asbestos-containing materials can release tiny asbestos fibers, too small to see, into the air. Workers and others who breathed asbestos fibers over many years have developed asbestos-related diseases, including asbestosis, pleural disease, lung cancer, and mesothelioma. Asbestos occurs naturally in certain types of rock. Large amounts of asbestos in rocks can look like long fibers, but each asbestos fiber is too small to see with the naked eye. Asbestos fibers do not dissolve in water or evaporate. They resist heat and fire and cannot be broken down easily by chemicals or bacteria.

  1. Certain areas of the country have natural deposits of asbestos near the ground surface.
  2. Asbestos in Products Because of its sturdy properties, asbestos was mined and used in making many products, including insulation, fireproofing and acoustic materials, wallboard, plaster, cement, floor tiles, brake linings, and roofing shingles.

Beginning in the 1970s, the United States banned many uses of asbestos, but asbestos is still present in old materials and is still used in products such as automobile brakes and roofing materials. Asbestos may also be present in other commercial products, such as vermiculite (especially vermiculite from Libby, Montana) and talc.

Serpentine class: chrysotile (also known as white asbestos) Amphibole class: amosite (brown asbestos), crocidolite (blue asbestos), anthophyllite, tremolite, and actinolite

Exposure to either chrysotile or amphibole asbestos increases the risk of disease. However, amphiboles remain in the lung for a longer period of time. Exposure to amphiboles may result in a higher risk of developing mesothelioma than exposure to chrysotile.

Can you live a normal life with asbestos?

When should I see my GP? – If you think you have might have been exposed to asbestos in the past and have symptoms of an asbestos-related condition, it’s important your GP knows. However, it is not a reason to worry. Most people do not develop serious or life-threatening lung disease as a result of exposure to asbestos.

any past or present jobs with an asbestos risk living with someone who has worked in a job with an asbestos risk (you may have inhaled asbestos fibres that they brought back home) DIY or other situations where you might have been exposed to asbestos ensuring your exposure to asbestos is documented in your medical records your symptoms and how to relieve them tests you might need whether you should see a specialist.

How long do you have to be exposed to asbestos for it to affect you?

Asbestos Exposure and Cancer Risk Fact Sheet Asbestos is the name given to six minerals that occur naturally in the environment as bundles of fibers that can be separated into thin, durable threads for use in commercial and industrial applications. These fibers are resistant to heat, fire, and chemicals and do not conduct electricity.

  1. For these reasons, asbestos has been used widely in many industries.
  2. Additional asbestos-like minerals are found in the natural environment, including erionite.
  3. Chemically, asbestos minerals are silicate compounds, meaning they contain atoms of silicon and oxygen in their molecular structure.
  4. Asbestos minerals are divided into two major groups: Serpentine asbestos and amphibole asbestos.

Serpentine asbestos includes the mineral chrysotile, which has long, curly fibers that can be woven. Chrysotile asbestos is the form that has been used most widely in commercial applications. Amphibole asbestos includes the minerals actinolite, tremolite, anthophyllite, crocidolite, and amosite.

Amphibole asbestos has straight, needle-like fibers that are more brittle than those of serpentine asbestos and are more limited in their ability to be fabricated (, ). Asbestos has been mined and used commercially in North America since the late 1800s. Its use increased greatly during World War II (, ).

Since then, asbestos has been used in many industries. For example, the building and construction industries have used it for strengthening cement and plastics as well as for insulation, roofing, fireproofing, and sound absorption. The shipbuilding industry has used asbestos to insulate boilers, steam pipes, and hot water pipes.

  • The automotive industry uses asbestos in vehicle brake shoes and clutch pads.
  • Asbestos has also been used in ceiling and floor tiles; paints, coatings, and adhesives; and plastics.
  • In addition, asbestos has been found in vermiculite-containing garden products and some talc-containing crayons.
  • In the late 1970s, the U.S.

Consumer Product Safety Commission (CPSC) banned the use of asbestos in wallboard patching compounds and gas fireplaces because the asbestos fibers in these products could be released into the environment during use. In addition, manufacturers of electric hairdryers voluntarily stopped using asbestos in their products in 1979.

In 1989, the U.S. Environmental Protection Agency (EPA) banned all new uses of asbestos; however, uses developed before 1989 are still allowed. The EPA also established regulations that require school systems to inspect buildings for the presence of damaged asbestos and to eliminate or reduce asbestos exposure to occupants by removing the asbestos or encasing it ().

In June 2000, the that the risk of children’s exposure to asbestos fibers in crayons was extremely low.U.S. manufacturers of these crayons agreed to eliminate talc from their products. In August 2000, the EPA conducted a series of tests to evaluate the risk for consumers of adverse health effects associated with exposure to asbestos-contaminated vermiculite.

The EPA concluded that exposure to asbestos from some vermiculite products poses only a minimal health risk. The EPA recommended that consumers reduce the low risk associated with the occasional use of vermiculite during gardening activities by limiting the amount of dust produced during vermiculite use.

Specifically, the EPA suggested that consumers use vermiculite outdoors or in a well-ventilated area; keep vermiculite damp while using it; avoid bringing dust from vermiculite into the home on clothing; and use premixed potting soil, which is less likely to generate dust ().

The regulations described above and other actions, coupled with widespread public concern about the health hazards of asbestos, have resulted in a significant annual decline in the U.S. use of asbestos. Domestic consumption of asbestos amounted to about 803,000 metric tons in 1973, but it had dropped to about 360 metric tons by 2015 (, ).

People may be exposed to asbestos in their workplace, their communities, or their homes. If products containing asbestos are disturbed, tiny asbestos fibers are released into the air. When asbestos fibers are breathed in, they may get trapped in the lungs and remain there for a long time.

  • Over time, these fibers can accumulate and cause scarring and, which can affect breathing and lead to serious health problems ().
  • Asbestos has been classified as a known human carcinogen (a substance that causes cancer) by the U.S.
  • Department of Health and Human Services (HHS), the U.S.
  • Environmental Protection Agency (EPA), and the International Agency for Research on Cancer (IARC) (,,, ).

According to IARC, there is sufficient evidence that asbestos causes (a relatively rare cancer of the thin membranes that line the chest and abdomen), and cancers of the lung, larynx, and ovary (). In fact, it is thought that most mesotheliomas are due to asbestos exposure ().

  • There is limited evidence that asbestos exposure is linked to increased risks of cancers of the stomach, pharynx, and colorectum ().
  • Asbestos exposure may also increase the risk of asbestosis (an inflammatory condition affecting the lungs that can cause shortness of breath, coughing, and permanent lung damage) and other nonmalignant lung and pleural disorders, including pleural plaques (changes in the membranes surrounding the lung), pleural thickening, and benign pleural effusions (abnormal collections of fluid between the thin layers of tissue lining the lungs and the wall of the chest cavity).

Although pleural plaques are not precursors to lung cancer, evidence suggests that people with pleural disease caused by exposure to asbestos may be at increased risk for lung cancer (, ). Erionite has also been classified as a known human carcinogen by IARC () and by HHS ().

  1. It is by the EPA.
  2. Everyone is exposed to asbestos at some time during their life.
  3. Low levels of asbestos are present in the air, water, and soil.
  4. However, most people do not become ill from their exposure.
  5. People who become ill from asbestos are usually those who are exposed to it on a regular basis, most often in a job where they work directly with the material or through substantial environmental contact.

Since the early 1940s, millions of American workers have been exposed to asbestos. Health hazards from asbestos fibers have been recognized in workers exposed in the shipbuilding trades, asbestos mining and milling, manufacturing of asbestos textiles and other asbestos products, insulation work in the construction and building trades, and a variety of other trades.

Demolition workers, drywall removers, asbestos removal workers, firefighters, and automobile workers also may be exposed to asbestos fibers. Studies evaluating the cancer risk experienced by automobile mechanics exposed to asbestos through brake repair are limited, but the overall evidence suggests there is no safe level of asbestos exposure (, ).

As a result of government regulations and improved work practices, today’s workers (those without previous exposure) are likely to face smaller risks than did those exposed in the past. Individuals involved in the rescue, recovery, and cleanup at the site of the September 11, 2001, attacks on the World Trade Center (WTC) in New York City are another group at risk of developing an asbestos-related disease.

Because asbestos was used in the construction of the North Tower of the WTC, when the building was attacked, hundreds of tons of asbestos were released into the atmosphere. Those at greatest risk include firefighters, police officers, paramedics, construction workers, and volunteers who worked in the rubble at Ground Zero.

Others at risk include residents in close proximity to the WTC towers and those who attended schools nearby. These individuals will need to be followed to determine the long-term health consequences of their exposure (). However, it is important to note that any symptoms these individuals experience may be related to exposure to debris components other than asbestos.

  • Although it is clear that the health risks from asbestos exposure increase with heavier exposure and longer exposure time, investigators have found asbestos-related diseases in individuals with only brief exposures.
  • Generally, those who develop asbestos-related diseases show no signs of illness for a long time after exposure.

It can take from 10 to 40 years or more for symptoms of an asbestos-related condition to appear (). There is some evidence that family members of workers heavily exposed to asbestos face an increased risk of developing mesothelioma (). This risk is thought to result from exposure to asbestos fibers brought into the home on the shoes, clothing, skin, and hair of workers.

To decrease these exposures, Federal law regulates workplace practices to limit the possibility of asbestos being brought home in this way. Some employees may be required to shower and change their clothes before they leave work, store their street clothes in a separate area of the workplace, or wash their work clothes at home separately from other clothes ().

Cases of mesothelioma have also been seen in individuals without occupational asbestos exposure who live close to asbestos mines (). Several factors can help to determine how asbestos exposure affects an individual, including:

  • Dose (how much asbestos an individual was exposed to)
  • Duration (how long an individual was exposed)
  • Size, shape, and chemical makeup of the asbestos fibers
  • Source of the exposure
  • Individual, such as smoking and pre-existing lung disease
  • Genetic factors, such as having a in BAP1 ()

Although all forms of asbestos are considered hazardous, different types of asbestos fibers may be associated with different health risks. For example, the results of several studies suggest that amphibole forms of asbestos may be more harmful than chrysotile, particularly for mesothelioma risk, because they tend to stay in the lungs for a longer period of time (, ).

  1. Many studies have shown that the combination of smoking and asbestos exposure is particularly hazardous.
  2. Smokers who are also exposed to asbestos have a risk of developing lung cancer that is greater than the individual risks from asbestos and smoking added together (, ).
  3. There is evidence that quitting smoking will reduce the risk of lung cancer among asbestos-exposed workers ().

Smoking combined with asbestos exposure does not appear to increase the risk of mesothelioma (). However, people who were exposed to asbestos on the job at any time during their life or who suspect they may have been exposed should not smoke. Individuals who have been exposed (or suspect they have been exposed) to asbestos fibers on the job, through the environment, or at home via a family contact should inform their doctor about their exposure history and whether or not they experience any symptoms.

  • Shortness of breath, wheezing, or hoarseness
  • A persistent cough that gets worse over time
  • in the (fluid) coughed up from the lungs
  • Pain or tightening in the chest
  • Difficulty swallowing
  • Swelling of the neck or face
  • Loss of appetite
  • Weight loss
  • or

A thorough, including a and lung function tests, may be recommended. The chest x-ray is currently the most common tool used to detect asbestos-related diseases. Although chest x-rays cannot detect asbestos fibers in the lungs, they can help identify any early signs of lung disease resulting from asbestos exposure ().

  1. A lung biopsy, which detects asbestos fibers in pieces of lung tissue removed by, is the most reliable test to confirm exposure to asbestos ().
  2. A is a less invasive test than a biopsy and detects asbestos fibers in material that is rinsed out of the lungs ().
  3. It is important to note that these procedures cannot determine how much asbestos an individual may have been exposed to or whether disease will develop.

Asbestos fibers can also be detected in urine, mucus, and feces, but these tests are not reliable for determining how much asbestos may be in an individual’s lungs (). The Occupational Safety and Health Administration (OSHA) is a component of the U.S.

  • Department of Labor (DOL) and is the Federal agency responsible for health and safety regulations in maritime, construction, manufacturing, and service workplaces.
  • OSHA established regulations dealing with asbestos exposure on the job, specifically in construction work, shipyards, and general industry, that employers are required to follow.

In addition, the Mine Safety and Health Administration (MSHA), another component of DOL, enforces regulations related to mine safety. Workers should use all protective equipment provided by their employers and follow recommended workplace practices and safety procedures.

For example, National Institute for Occupational Safety and Health (NIOSH)-approved respirators that fit properly should be worn by workers when required. Workers who are concerned about asbestos exposure in the workplace should discuss the situation with other employees, their employee health and safety representative, and their employers.

If necessary, OSHA can provide more information or make an inspection. Information about regional offices can also be found on OSHA’s website at, More information about asbestos is available on OSHA’s page, which has links to information about asbestos in the workplace, including what OSHA standards apply, the hazards of asbestos, evaluating asbestos exposure, and controls used to protect workers.

Does asbestos get worse over time?

What is the prognosis (outlook) for people with asbestosis? – Asbestosis can’t be cured. You can’t reverse the damage from the disease. Once you breathe in asbestos fibers, they stay in your body. Your prognosis varies depending on how long and how much exposure you had to the particles.

  1. Many people with mild asbestosis live fulfilling lives for many years after being diagnosed, but some cases get worse over time.
  2. You may need medical management throughout your life.
  3. Your healthcare provider is likely to order chest X-rays and lung function tests every few years to look for changes in the scarring in your lungs.

How do you coat an asbestos roof?

How Does it Work? – Asbestos Roof Coating is manufactured using premium grade polymers, specially selected for roofing applications requiring exceptional durability, U.V resilience and waterproofing qualities. As the coating cures it keys to the surface, forming a permanent bond which encapsulates the fibres in the sheet substrate, preventing them from being exposed either by weathering or abrasion.

  1. If Asbestos Sealer & Primer has been used to prepare the surface for coating, impact protection is further enhanced as it hardens the surface thereby reinforcing the Asbestos Roof Coating’s mechanical strength.
  2. Here in the U.K, asbestos roof sheets were manufactured and installed for most of the 20th Century.

The familiar corrugated profile sheets helped thousands of military buildings to be rapidly assembled in kit form during WW2, and these can still be found to this day, scattered throughout the country. The point is that asbestos cement roofing (white asbestos) is a very durable material, which in a majority of cases has outlived its anticipated lifespan by decades.

In fact Kingfisher has been involved in supplying sealers and coatings to roofs which date as far back as the 1930s! This means that building maintenance professionals and property owners are likely to be maintaining asbestos roofs for many years to come and will need technically superior coatings to facilitate that.

Repair or Replace? Although the “white asbestos” (chrysotile) used in the manufacture of roofing sheets was the least toxic asbestos variant, it is still has the potential to be hazardous, which is why the management and removal protocols are strictly enforced.

The cost of complete removal and replacement of asbestos cement roof sheets, can therefore be considerable, often prompting stakeholders to consider repair options. The second option considered, especially in storage or agricultural buildings is to simply replace the asbestos sheets with modern plastisol coated, steel profile sheeting.

However, it is worth remembering that one of the major reasons why asbestos cement roof sheets became so popular in the first place, was that compared to corrugated “tin” (steel profile), they did not suffer from condensation. By contrast, “tin” roofed buildings famously rained condensation on workers, stock, machinery, farm animals or anything else unfortunate enough to be inside.

  1. Of course you can opt for composite insulated panels that won’t exhibit condensation but they are at least 2.5 times the cost! Or you can choose modern cement fibre roof sheets (nearest equivalent to the old AC sheets) but these are also more costly than steel profile.
  2. So for example, if you store your classic car in a garage with an asbestos roof, it may be that this is as at least as good an option as modern cement fibre and definitely better than new steel profile.

Repair & re-coating should at the very least be considered. How to use Asbestos Roof Coating? 1. “Bio Wash” Roof: (kills moss, green mould & lichens) Liberally spray the entire roof surface with Kingfisher “Bio Wash” using a low pressure sprayer (as for garden weed-killer) and leave for seven days to activate.2.

Clean Roof: (remove debris) Thoroughly damp the roof by mist spraying with water (suppresses release of harmful fibres) and brush/ scrape the dead moss and other surface dirt and laitance into bags for disposal as AC waste. Alternatively for larger areas the “closed box” pressure washing method described in HSE doc A12 can be used but the waste sludge and water run- off have to be collected in the gutters and down pipe.3.

Repair Roof: General Sealers and coatings should only be applied to essentially “sound” roofs so a pre-inspection of the roof structure and surface condition should always be undertaken by a competent person (e.g. experienced roofing contractor or structural engineer) before commencing works.

This will determine whether the supporting steel / timbers are in need of repair and identify any cladding / roof sheets which are damaged or decayed beyond practical repair and therefore need complete replacement. In addition this inspection will typically inform the choice of access equipment to be used for safe execution of the works.4.

Minor Repairs: Any minor cracks or holes, especially around fixings can be filled with “Parabond” hybrid polymer sealant. Cracks of up to 3mm can be successfully filled by applying a bead of “Parabond” along the crack and then pressing / smearing it firmly into the damaged area.5.

  1. Larger Repairs: Bigger cracks or holes can be bridged with “Kingfisher Fibreseal” fibre reinforced roofing compound & “Kingfisher Scrim Mesh”.6.
  2. Primer: Apply one coat of Kingfisher Asbestos Sealer & Primer by brush or low pressure (non-atomising) spray to consolidate and harden the substrate.7.
  3. Application: Apply 2 x coats of Asbestos Roof Coating by brush or high pressure airless sprayer.

Cut-in edges and around detailing such as roof-lights, vents etc. with a premium grade paint brush. Generally allow 6 to 8 hours between coats although in warm conditions this may be reduced to as little as two hours. If applying by sprayer, ideally use a 17 thou tip blade (nozzle size) and set the output pressure to 2500 psi.

  • How much will I need?
  • The coverage rate is 4 to 6 sq m per litre, so a 10 litre pail treats approximately 50 sq m.
  • a) Do not apply to damp surfaces or in wet weather
  • b) Always consult a competent Health & Safety professional for guidance on working at height, especially on fragile surfaces like AC sheeting.
  • c) Ensure you inform yourself regarding correct PPE and waste disposal protocols for working with asbestos cement roof sheets.

What can I cover a asbestos roof with?

Budget: Is coating cheaper than over cladding asbestos roofing? – Coating has traditionally been the cheaper method of waterproofing an asbestos roof. Fluctuating steel prices can make over-cladding vary in cost, steel being the favoured material used in over cladding.

  1. As for how this will exactly affect the price differential between the two systems, no one can know for sure at this time.
  2. Of course, it’s not only about the price of the product.
  3. Both solutions need access to the roof via cherry pickers and scaffolding, adding labour and hire costs to the bill.
  4. But this is where coating clearly trumps over cladding.

Coating a roof can be quicker and easier, meaning on site time is reduced and scaffolding isn’t required for as long. There’s also extra construction costs involved in over cladding, such as meeting current regulations for insulation, and ensuring the building structure is strong enough to support another roof.

Can you use high pressure water spray on asbestos?

Possible control measures to prevent similar incidents – You should never use high-pressure water spray equipment to prepare for painting, coating or sealing of asbestos cement roofs as there is no system of use that can effectively capture or suppress asbestos fibres in such circumstances.

  1. A PCBU must not use, direct, or allow a worker to use high pressure spray on asbestos or ACM.
  2. Before carrying out maintenance of a roof, consider whether asbestos could be present.
  3. When working on buildings constructed before 1990, it is likely asbestos could be present in roofing and other sheet materials.

Identifying asbestos or ACM is the first step in managing the risk of exposure to asbestos. As there may be more than one person in the workplace responsible for this duty, it is important that all duty holders consult, cooperate and coordinate with each other as well as consulting with workers and health and safety representatives.

There may be a person within the business who is competent to identify asbestos. If there is not, an external competent person should be engaged. There are a number of ways to control the risks associated with asbestos or ACM in the workplace. PCBU’s must always aim to eliminate the hazard and associated risk first, for example by removing the asbestos sheeting.

The removal of asbestos cement roof sheeting must be performed in accordance with the Work Health and Safety Regulation 2011, If it is not reasonably practicable to remove the asbestos, then other control measures must be implemented to ensure people are not exposed to airborne asbestos.

Enclosing the asbestos – creating a structure built around the asbestos so that it is completely covered to prevent exposure of the asbestos to air and other substances. Enclosure should only be used on non-friable asbestos where removal is not reasonably practical and where the asbestos is at risk of damage from work activities.Encapsulating – the asbestos that is encapsulated in a resilient matrix (e.g. in reinforced plastics, vinyls, resins, mastics, bitumen, flexible plasters and cements) has little opportunity to release airborne asbestos unless the matrix is damaged. This type of encapsulation will seal any loose fibres into place and should be used only when the original asbestos bond is still intact.Sealing – Sealing is the process of covering the surface of the material with a protective coating over the asbestos to prevent exposure to airborne asbestos. Sealing asbestos is the least effective method for controlling the release of airborne asbestos. It should only be considered as an interim control while a more effective control such as removing or enclosing can be implemented.

Workers will need to use personal protective equipment (PPE) in combination with other effective control measures when working with asbestos. Your selection and use of PPE should be based on your risk assessment. PPE includes but not limited to disposable coveralls, gloves, boot covers, respirators and protective eyewear.

Administrative controls can be used to minimise any remaining risks (e.g. safe work practices), so far as is reasonably practicable and can include work methods or procedures that are designed to minimise exposure to asbestos fibres as well as the information, training and instruction needed to ensure workers can work safely.

Administrative control measures and PPE do not control the hazard at the source. They rely on human behaviour and supervision and used on their own tend to be the least effective in minimising risks. You must not use administrative controls exclusively to minimise the risk of falls unless it is not reasonably practicable to use a higher order control.
