You can lift and safely place the vinyl in a bag that is resistant, and does not have any holes. Jul 13, · Equipment for safe asbestos flooring removal includes: Plastic sheets to seal off the work area. To keep asbestos contamination from spreading, workers must cover air vents, doors and windows with plastic flaps and turn off the heating, ventilation and air conditioning unit.

This document series assists building buyers, owners or occupants in reducing the risk of asbestos exposure from flooring that contains or is suspected to contain asbestos. We provide photographs 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. We begin by suggesting that you should not remove asbestos-containing floor tile unless it is really necessary. As with asbestos-containing products in general, the asbestos hazard at a building may be greater from disturbing asbestos-containing materials ACM than if they were left alone or covered up.
But in some cases, particularly during certain building renovations or when asbestos-containing flooring is in poor condition and cannot easily be left in place, removal may be necessary. Here is what the University of Minnesota has to say about the hazards of this type of asbestos-containing floor tiles:.
Flooring that contains asbestos, when intact and in good condition, is generally considered nonfriable and is not hazardous. Heat, water, weathering or aging can weaken flooring to the point where it is considered friable.
Friable flooring includes any material containing more than 1 percent asbestos that can be crumbled, pulverized or reduced to powder with hand pressure.
This includes previously nonfriable flooring material which has been damaged to the extent that it may be crumbled, pulverized or reduced to powder by hand pressure.
Flooring can also be made friable during its removal. Friable materials how to find coordinates on a web page release asbestos fibers into the air.
Once in the air, asbestos fibers present a health hazard to people who inhale those fibers. Non-friable miscellaneous ACM includes floor tilesasbestos cement sheet transite boardsiding shingles, asphalt roofing shingles, laboratory bench tops and even chalkboards. These materials may become friable with age, and under harsh conditions. Category I non-friable ACM must be carefully examined to determine if the material is in poor condition, that is, if the binding material is losing its integrity, exhibited by peeling, cracking or crumbling; and is also friable.
Miscellaneous materials are wetted in manners similar to those used to wet other categories of RACM. Coverings are saturated with a wetting agent before removal and the asbestos-containing portions fully penetrated with the agent prior to, during and after their removal, while stored in the removal area, and while being placed into disposal containers. Miscellaneous materials that don't absorb water readily e.
A misting sprayer may be used to diminish airborne asbestos fiber levels. Leaving old ACM or PACM flooring in place in a building is the first choice approach where that flooring is itself no longer serviceable.
Leaving the asbestos-containing flooring material in place will generally be the lowest-risk approach as it is the disturbance by removal of asbestos containing material that significantly increases the risk of airborne asbestos in buildings.
Where loose floor tiles or damaged sections of sheet flooring have left shallow holes, uneven surfaces, or depressions in the original tile or sheet resilient floor covering there are these approaches to producing a suitably smooth surface over which new non-asbestos sheet or tile floor coverings can be installed atop the old flooring:.
Assumption of asbestos content : unless you know from specific test or other certain data that [in our opinion pre] resilient floor tile or sheet flooring, floor backing, adhesives, and underlayment are free of asbestos, for safety, assume that the material contains asbestos. No mechanical disturbance : do not bead-blast, chip, drill, dry-scrape, mechanically chip, pulverize, or saw or use any other mechanically disruptive method on any resilient flooring tile, sheet flooring, underlayments, subflooringfloor backing, felt linings or underlayments, or on generally black asphalt-based cutback adhesives or other adhesives some tan adhesives contained asbestos as well.
EPA with minor additions of explanation and adaptation from additional sources. Major repairs must be done only by a professional trained in methods for safely handling asbestos. Minor repairs should also be done by professionals since there is always a risk of exposure to fibers when asbestos is disturbed.
Doing minor repairs yourself is not recommended since improper handling of asbestos materials can create a hazard where none existed. Removal is usually the most expensive method and, unless required by state or local regulations, should be the last option considered in most situations. This is because removal poses the greatest risk of fiber release.
However, removal may be required when remodeling or making major changes to your home that will disturb asbestos material. Also, removal may be called for if asbestos material is damaged extensively and cannot be otherwise repaired.
Removal is complex and must be done only by a contractor with special training. Improper removal may actually increase the health risks to you and your family. For employees who are, or may reasonably be expected to be exposed to airborne concentrations of asbestos fibers above the permissible limits set by the Occupational Safety and Health Administration OSHAregulations require that the employer conduct both initial what is the job about periodic air sampling.
If the ACM is currently in good condition, increases in airborne asbestos fiber levels at some later time may provide an early warning of deterioration or disturbance of the material. In that way, supplemental air monitoring can be a useful management tool.
If an owner chooses to use air monitoring in an "early warning" context, a knowledgeable and experienced individual should be consulted to design a proper sampling strategy. See Useful Links for more information on air monitoring. This air monitoring should supplement, not replace, physical and visual inspection. Visual inspection can recognize situations and anticipate future exposure e. Note that the collection of air samples for supplementary evaluation should not use aggressive air sampling methods.
Aggressive sampling methods, in which air is deliberately disturbed or agitated by use of a leaf blower or fans, should only be used at the completion of an asbestos removal project inside the abatement containment area. Phase contrast microscopy PCM how to safely remove asbestos floor tiles, which is commonly used for personal air sample analysis and as a screening tool for area air monitoring, cannot distinguish between asbestos fibers and other kinds of fibers which may be present in the air.
PCM analysis also cannot detect thin asbestos fibers, and does not count short fibers. However, the more accurate information on actual levels of airborne asbestos fibers that can be derived from TEM should be more beneficial to the building owner who elects to use supplemental air how to safely remove asbestos floor tiles in the asbestos management program.
See ReferencesU. EPA, Dec. A consultant knowledgeable in air sampling and analysis protocols can be contacted for recommendations if the building owner or APM has limited knowledge in this area. You may call NIST at We were hoping you could take a look at this image fo determine if it contains asbestos? The house was built aroundbut we arent sure if this is the original tile. Jared, no one can say for sure what a material contains from just a photo, but the image indeed looks like a 's vintage asphalt or vinyl asbestos floor installation, possibly a Kentile floor as those used many pattern inserts.
Watch out : it looks as if the breakup is making a dusty mess - something to be avoided in any case. If you are facing a costly demolition then it would make sense to confirm asbestos content using a certified asbesto test lab. Else it makes sense to treat the material as "presumed asbestos containing" or "PACM" flooring based on age and appearance.
If the what needs water to live is quite uneven that would show up through a flexible floor covering such as sheet vinyl; but if you're installing any type of thicker plank laminate flooring you should be fine.
I just teared down vinyl flloor in my kitchen area. How to safely remove asbestos floor tiles parts came out easily but most backing still attatched to subfloors. Can I put laminate floor over backing or should I have professional remove it? Is it safe to leave backing underneath laminate floor?

Not one broken tile in the whole basement. It took a little while but worked like a hot dandy. Joe, That's an excellent question; the answer isn't a simple yes or no.
IF the basement work area can be completely contained and its air pressure properly managed so as to isolate it from the upper floors AND IF nothing goes wrong during that process THEN the upstairs is protected from asbestos dust. When a basement floor containing asbestos is being removed professionally can the homeowners stay in the house? There won't be "concrete tiles" likely to be found in a basement but we're probably simply having a bit of communication confusion. Asphalt asbestos or vinyl asbestos floor tiles that contain asbestos, IF they are intact and adhered to the slab, are low risk but if the tiles are loose and coming up then it would make sense to either treat them as presumed to contain asbestos or to have a sample tested.
In my opinion - which is wildly speculative since you don't attach photos nor give details about the condition of the floor below the carpeting - is that if the carpeting is not glued down it would make sense to lift the carpet and actually look rather than just guessing all over the place. If the floor is intact, the US EPA and other expert advice is that the safest and least costly approach is to leave it in place and what is a conical strainer used for it over with new materials.
If there are just a few loose tiles that can be lifted out without demolition chopping sanding grinding sawing then that position wouldn't change.
Some of the people involved in a question like this are perfectly comfortable spending your money to reduce their risk.
My basement flooded - it has old concrete tiles with carpeting over them. They say they cannot pull up the carpeting without the testing because the concrete tiles may get damaged.
Should I have the testing done? If it comes back positive for asbestos what are my options as far as repairs? I would prefer they not tear up the entire basement with an aggressive abatement if it can be avoided. Will the carpet and concrete tiles need to be completely removed? Or are they just playing on a homeowners fears? I have a vinyl floor containing asbestos. A few of the 12" tiles are how to manage arthritis pain up into small 1" pieces.
I plan to cover the entire floor with non-asbestos containing material but if I remove the lose broken pieces I will be left with areas that are lower by the thickness of the original tile. I have enough of the original tile to replace the broken areas. Sorry but there's no single right answer to parts of planes and what they do question of the last year that asbestos was used in flooring.
Prohibitions against the use of asbestos in flooring varied by country. In the US you wouldn't expect asbestos in flooring past week early to mids. In the UK and some other countries that might be Jack I can't answer a safety question about the performance of an unknown contractor in an unknown building on an unknown floor.
In general, EPA and everyone else familiar with this topic point out that safest and least costly is to leave old flooring in place, covering it over with new flooring. In a situation where that can't be done and demolition must be performed, there are guidelines for doing that process safely and properly.
Mar 11, · Remove asbestos-containing material carefully: It is impossible to remove asbestos tiles intact. In order to remove them safely, you must break every tile into dozens of pieces. Remember that breaking asbestos tiles poses a serious risk of releasing asbestos fibres into the air and having them spread to other rooms in your house. Y N If your flooring contains asbestos, is removal the best option? Asbestos is a problem only if fibers are released to the air. There are safer, easier, and less-expensive alternatives to removing your asbestos-backed sheet vinyl flooring. Rather than removing it, consider installing a new floor . Vinyl asbestos floor tiles must be removed, handled and disposed of in a manner that keeps the material in predominantly whole pieces to be considered nonfriable. The method of removal cannot shatter (broken into 4 or more pieces), crumble, pulverize, or reduce the material to dust.
Before you start this task you need to think about whether you want to do this job on your own or if you wish to hire a professional contractor to take care of the asbestos floor tiles. Asbestos is a very dangerous thing to deal with. This material was used because of its convenience to manufacture, its price, and because it was not flammable.
However, over the years it has been proven that asbestos causes major illnesses like cancer, and that is the reason why the use of asbestos materials has been stopped in the United States of America. The reason to do things on your own is to save a little money, however, there are times when you should think about your health. In the case that you wish to do this job on your own, you can follow these guidelines as reference, but you must also take into consideration your state's building codes, and expert advice.
The number one thing to remember is that you must do whatever is necessary to remove whole pieces of the tile. If you do not do so the particles can float on the air and they can be easily breathed causing asbestosis and other pulmonary illnesses. For this reason, you need to isolate the area by putting plastic over the doors of the place where you are working, covering cup boards, windows, and vents.
Use the plastic to cover the entrances and use the duct tape to secure the plastic. Wet the floor with water and a spray bottle or a hose in order to keep the dust particles from floating on the air.
You must wear coveralls, dust mask, goggles, gloves, and boots. This is to keep you from getting hurt and from breathing any asbestos particles. Take a utility knife and cut the asbestos into manageable pieces. Next, start lifting the asbestos vinyl tiles and with the scraper keep on separating the tile from the floor.
You can lift and safely place the vinyl in a bag that is resistant, and does not have any holes. Make sure to label the bag stating that it is dangerous material and that it is asbestos. Remove any extra dust by simply using a wet towel. Make sure to always keep on changing the water and you can use liquid detergent to better clean the area.
You can also mop the area using the mop. You cannot throw your asbestos material in the landfill. You need to consult your local government to find out where you can safely dispose of the asbestos. This guide on how to safely remove asbestos floor tile help you get the job done. Remember, your safety should come first and there's nothing wrong with hiring a pro.
