Certified asbestos remediators or labs: this article warns about un-supervised or un-trained environmental cleanup companies or work crews handling asbestos, lead, mold, and similar indoor contaminants, including identification of amateur or improper asbestos "abatement" projects that failed to properly remove materials or that left abandoned asbestos materials in place.

Certification & Licensing for Asbestos, Lead Paint, or Mold Abatement, Removal, & Cleanup Companies: Consumer Warning about Environmental Cleanup Contractors
Some problems we have found in the field when inspecting indoor asbestos, lead paint, mold, and other indoor environmental cleanup projects include:
The Occupational Health and Safety Act and are in Ontario Regulation 278/05 provides a clearly-written and comprehensive guide to cleaning up and disposing of asbestos containing materials in or on buildings. That document describes a competent worker for asbestos cleanup as:
The same regulation provides instructions on providing information for workers involved with asbestos containing materials:
Watch out: Failure to take these precautions risks serious consequences including contamination of other building areas by asbestos dust and debris, health risks and harm to the cleanup workers themselves, and future health risks and harm to building occupants as well as potential issues should the property later be offered for sale. These concerns pertain to other indoor and building-related outdoor environmental concerns such as lead paint removal and cleanup and mold remediation projects too. Watch out: in 2010 The New York Times reported [paraphrasing from that article] that over a five year period beginning in 2001 hundreds of asbestos-removal training certificates were given to people who had completed no training whatsoever. The U.S. E.P.A. reported [according to the Times] that Albania Deleon, operating Environmental Compliance Training, a certified asbestos-removal training school in Methuen, MA and the largest such asbestos cleanup training school in the state. 65 to 80 percent of those receiving certification as qualified asbestos removal experts had not received the necessary training. Many "Graduates from Environmental Compliance Training also obtained jobs through a temporary employment agency also owned by Deleon, were sent out to perform dangerous asbestos cleanup jobs, and were paid "under the table". Deleon was convicted in 2008 of criminal charges but fled the U.S.. She was captured in the Dominican Republic in 2008. Asbestos Cement Roof Washing Troubles - "... they power-washed my asbestos cement roof ..."
Question: Is power-washed asbestos-cement roof runoff an environmental hazard?I live in Brantford Ontario and a building in my neighbourhood has was I think is a corrugated asbestos roof. Last weekend some workmen power washed it. The run off, when dried, looked like grey powder and lifted from the pavement in "sheets" almost like parchment paper. I've attached a couple of photos. Does this present any danger or give cause for health concerns? - D.F., Brantford ONT Reply: Asbestos hazards are probably present, asbestos regulation violations may have occurred, and further steps are neededOPINION:
While wetting the material, something that would naturally occur during the power-washing of the cement-asbestos roof surface, would be expected to reduce the airborne level of asbestos during the actual washing process, although when properly performed, wetting to control asbestos particle release includes the addition of a wetting agent to the spray before it is applied. Power-washing a cement asbestos roof would leave substantial materials on the ground after the cleaning procedure. As the on-ground material dries asbestos fiber and particle risks are likely to be present. So it would be no surprise if the debris on the ground around the building in your photos contains a high level of asbestos fibers and particles. The material therefore may form an airborne asbestos hazard in the neighborhood, or as it washes into local storm drains, it may constitute an illegal and improper disposal of asbestos dust and debris. If the added cost to properly clean up this mess is going to be high (which we would guess is the case), it would be appropriate and inexpensive to collect a debris sample for testing by a local, certified asbestos testing lab to confirm that the contents are indeed contaminated at a level requiring professional cleaning. In addition, power-washing the roof surface risks increasing the friable nature of the material that remains on the building, as the cementious binding has been removed from the uppermost roof surface, first by normal weathering and second, and much more aggressively, by the power washing process. The building owners should address these questions immediately in order to reduce the spread and thus possible costs of a proper asbestos dust cleanup. Asbestos regulations for Ontario are published under the Occupational Health and Safety Act and are in Ontario Regulation 278/05 and provide a clearly-written and comprehensive guide to cleaning up and disposing of asbestos containing materials in or on buildings. Discussing [Type 1] asbestos operations that regulation states:
Lead Paint Cleanup Troubles - "... the lead paint dust was everywhere!"Question: Who Should I Use for Cleaning Up Lead Paint Dust Left by My Contractor?You’re going to love this one. (maybe not). We were getting the exterior of our house painted. Since we have young kids (8 and 10), I thought I was careful to choose a painter only after discussing with the painter to discuss how they dealt with lead. Our house painters seemed to do a good job (removing paint under a tarp to contain the lead, etc) until I went into our garage and noticed a white dust coating over everything and also found their mask, lights, tarp, etc next to my kids bikes! I tested contents throughout the garage and it’s a hot zone. The lead paint dust was everywhere and we had lots of items stored all over the garage. The good part is the vendor is taking ownership. He would like to remove everything from the garage, wipe the articles down and box them, and then power wash the garage. (even the overhead electric door opener probably has dust on it.) I’m wondering whether it’s better to vacuum everything first (contents and entire garage, then wash down)and with a $500 HEPA lead specific vac vs just using a Shop Vac with HEPA filter. Any suggestions would be most appreciated. Maybe there’s a business for inspectors who will check the premises for lead during and after a paint job. Maybe I need to hire someone watching the painters next time? We have drains in the garage and driveway. Theoretically, we could filter the water where it drains. Easy to say. I think the ultimate challenge will be to determine after the clean up whether it's really clean. How do I know whoever will wipe every bottle, toy,even fire wood? It's such a mess. Thanks - GK October 2010 Reply: A qualified professional company with expert supervision should be used for any environmental cleanupOur OPINION about this lead dust containment mistake is below:
Therefore you should be using a professional, trained, supervised lead paint or contaminated dust environmental cleanup company to handle this cleanup job. It's too bad, and surely an accident, but the lack of training or attention by the painter appears to have unavoidably increased the cost of this renovation job. Frequently Asked Questions (FAQs) about Do-it-yourself Asbestos, Lead, Mold Cleanup Jobs - can I do it myself? who should I call? Is it necessary?Question: Lead dust containment mistakes, and now I suspect asbestos dust problems: can I clean it up myself?We had a French drain installed in our basement yesterday and I just realized last night that it was possible that the floor tiles that were on the ground prior to removal might have been asbestos tiles. I have attached a picture of the tiles. They are 12x12 and 1/8 inch thick. I took a look at the pictures on your website and I don’t think that these match, but it is hard to tell with such a common pattern. If you could provide any assistance as to the likelihood of these containing asbestos I would appreciate it as I plan on keeping my 15 month old out of the house if it is likely to contain asbestos. I called an asbestos removal company and they won’t have any results until Tuesday- so if I have more information about the tile today that would help tremendously. I’d be happy to pay a consulting fee for this information. The house was built in 1950 and I am unsure when the flooring was installed in the basement so I have no idea whether it is pre or post 1986. If I were to treat it as if the remaining dust contained asbestos I know that it needs to be wet down and vacuumed with a HEPA vacuum. Can I handle the clean up myself? -- C.A. Reply: It depends ...Our caution in answering questions like this is out of worry that we give don't want to give a reader bad advice for a situation that we cannot accurately assess. Also we really can't judge the expertise and skill level of a do-it-yourself'er by email. Handling old floor tiles:See ASBESTOS FLOORING HAZARD REDUCTION A competent onsite inspection by an expert usually finds additional clues that help accurately diagnose a problem or even find another more dangerous problem that was unnoticed. That said, here are some things to consider: If the resilient floor tiles date from the 1980's or older, it's a reasonable precaution to presume that they contain asbestos - at least for the purpose of dust and demolition practices and cleanup. There is not much lost and plenty gained if you simply handle the demolition and cleanup as if the material contained asbestos - that means dust control and proper cleanup methods. Don't panic - it's not radioactive. It's dust disturbance from violent demolition and lack of dust control or improper cleanup that would be the most serious concern. If you sound too anxious there is a risk that someone will prey on that. Caution is, however, appropriate. About mopping up small suspect amounts of lead dust or asbestos dust:OPINION: we would be comfortable mopping up a small (a few square feet or less) of wet-down asbestos-suspect or lead-suspect dust and HEPA-vacuuming surrounding areas. In fact a well-informed do-it-yourself'er might be more careful and do a better job than an uninformed small-job contractor who may be just about the only worker one can line up to do very small building clean-up jobs. Be sure to read the EPA advice on these cleanups and also check with your state or provincial and local health or DEP folks for local regulations and advice as well as for legal disposal of waste. ASBESTOS MATERIAL REGULATIONS and ASBESTOS REMOVAL, Wetting Guidelines should be helpful. Also you might want to take a look at ASBESTOS RISK ASSESSMENT. For lead hazards, take a look at LEAD CONTAMINATION HAZARDS in the HOME. But for larger areas and/or where there is risk of cross contamination of other building areas, I'd certainly call a qualified, licensed, certified professional. Our OPINION about this lead dust containment mistake you have described is below: It sounds like a mistake to power wash the lead-paint-dusted garage interior: By power-washing the garage interior and simply allowing the wash-out to flow outdoors, you'll just be moving the contamination to the outdoor yard soil where your children play, to the street and as the wash dries, to air, and to neighbors, or the storm drain system Power-washing the garage interior, assuming some surfaces are insulated or covered with drywall, risks driving water into building cavities, creating a mold problem That approach certainly won't properly clean all of the items that are stored in the garage and are or may be contaminated with high levels of lead paint dust and debris. It sounds questionable to have a lead dust contamination cleanup done by a contractor or their crew who, from having created the problem in the first place, appear not properly trained. It sounds reasonable to HEPA vac and wipe all surfaces - that's part of what a lead abatement co would do, but they'd also probably have already set up a barrier between the garage and rest of the home. Therefore you should be using a professional, trained, supervised lead paint or contaminated dust environmental cleanup company to handle this cleanup job. It's too bad, and surely an accident, but the lack of training or attention by the painter appears to have unavoidably increased the cost of this renovation job. Question: Do I Need to Remove Asbestos Pipe Insulation? If So, Who Should Do It?Love the [InspectAPedia] website and has been very helpful in the home buying process! I got this note from my building inspector:
I was wondering if you had any insight or could help remedy the current issue of asbestos (attached test results) content found in pipe insulation in the basement crawlspace. I am also looking for an approximate cost to encapsulate approximately 15 to 20 feet of piping. Any help would be appreciated as well as contractors to call if you do not provide this service or questions to ask to make sure not a health issue. - M.M. Reply:It is not a coincidence that many companies who perform mold cleaning and remediation got their start in asbestos abatement. The standard of care for dust containment for asbestos cleanup projects has become the gold standard for avoiding cross contamination of a building with moldy dust as well.
The need to remove asbestos and even the need to encapsulate is not at all absolute. Certainly encapsulating asbestos pipe insulation in areas where it needs to be protected from damage is advised. When the material is damaged, releasing asbestos to the building, or when it is in a location where it is likely to be damaged and thus become a hazard, it is removed or encapsulated to protect it from damage.When asbestos pipe insulation is in good condition and located in an inaccessible area not exposed to damage, the remediator may advise you to leave the material alone. There is no information in your note that addresses these questions, though of course you or an expert may have already made that assessment. (Also see ASBESTOS RISK ASSESSMENT). If your pipe insulation looks like the asbestos material shown in our photo at left, indeed it's falling off and should be removed. Proper asbestos pipe insulation removal involves more than unwrapping and disposing of the insulation. The contractor will need to take measures to avoid spreading asbestos dust into the building (dust containment measures), and the pipes are usually cleaned and sometimes also sprayed with a sealant after the insulation itself is removed. That said, the cost of removing asbestos pipe insulation has dropped quite a bit since the public anxiety over this topic has also faded, and as there are many asbestos removal companies. We do not make individual contractor referrals, and we have no business nor financial relationship with companies who offer services, including some who may be listed at our website. ASBESTOS CLEANUP COMPANIES lists some clean-up companies in New York who have expertise in asbestos removal.
