Asbestos producing companies, complete list of companies and asbestos-products:

This article lists U.S. (and other) companies who were major producers of asbestos or asbestos-containing products. There were thousands of products that contained asbestos, some made by comparatively small businesses.

Where known we list the range of years over which each company produced or distributed asbestos-containing products or materials.

Therefore no list of asbestos product producers is likely to be complete. But these major asbestos-product producing companies were responsible for the production of the majority of products used over the range of asbestos-containing products and materials.

This article series assists building building buyers, owners, attorneys, engineers, environmental investigators 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.

InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers, products, or services discussed at this website.

Question: Did our demolition of a popcorn ceiling sprayed by a product from Murco Wall Products involve asbestos hazards?

Murco non-asbestos wall coating - cited & discussed at InspectApedia.com

Image: Murco Tex.M-1000 - current company product. While some Murco products contained asbestos, the current products, like this one, do not use asbestos. A company description of this current product is given below.

2021/04/10 by Anonymous:

I was doing some home clean-up and found an incredibly deteriorated bag of Murco M-1000 popcorn ceiling texture in a side shed outside.
https://www.murcowall.com/texture (at bottom of list). It fell apart as I tried to move it and I had to end up getting rid of it with a broom and blower.

I can't imagine a bag of texture has lasted through multiple owners since the house was built in 1978 (or 77). That'd be crazy to me. Still, we ran into asbestos in this house before (you and I had emailed about it a couple years back) so I'm always paranoid when I run into old building materials.

This product seems newer (even though the paper bag was a mess and could've been decades old) and is still sold by Murco (image on front of bag is the same), so I'm assuming things are ok but wanted to see if you had any knowledge I didn't. For what it's worth, this house did have popcorn ceilings in some spots (still does) and I tested multiple areas and they were all negative. I've also emailed Murco Wall. - Anonymous by private email

Moderator reply:

I understand that you got rid of the material itself but if you have the packaging I would like to see photos of all of the writing and labels and date codes

Reader follow-up:

I’m really sorry I don’t have that. The bag was really falling apart. The attached pic is how it looked, though (stock pic). The bag had browned/yellowed.

There was one part of the side of the bag that had the word asbestos on it, but I’m guessing it was more a general warning about it using respirators.

Sorry I don’t have more info than that. Bag had been outside for years and years and was just a mess. I can let you know what the company says.

Attaching a new one of how the bag looks (not the actual bag in question). It is just popcorn ceiling texture. A powdery substance and little pieces of styrofoam. The bag even says "vinyl base" on it, which I assume is to try and communicate "No asbestos." :-)

Moderator reply: asbestos in some older Murco products but not current Murco wall products.

You are showing the CURRENT Murco product, about which the company says

Murco M-1000

A powder product with polystyrene aggregated which produces a simulated acoustical ceiling finish. Designed for use on interior ceiling only. Available in fine, medium, and coarse aggregate sizes.

Can be used on gypsum panels, wood concrete, and plaster. High hide with exceptional whiteness make it ideal for covering surface defects and taping seams. This product may or may not be painted.

Three sizes available for simulated acoustic, high hide exceptionally white color, less fallout for more coverage, better wet viscosity control to prevent aggregate separation,  and better spraying properties to prevent fallout.

To address an asbestos question with data rather than speculation you would at the very least want to specify the particular building's country, city, age, and history of renovations so that we might have some idea when the spray-on popcorn ceiling or textured wall coating was applied.

You can see a list of products produced by Murco that contained asbestos  at  ASBESTOS PRODUCING COMPANIES & TRUSTS  to find Murco's products go to that page and go to its "M" section OR use your browser's on page search (ctrl-F) to find "MURCO"

Case Law Includes Asbestos Litigation involving Murco Wall Products

Murco, in various court cases, defended against asbestos claims, for various reasons including asserting that specific products did not contain asbestos or that Murco did not sell products in states where claimants asserted that Murco products were used (there is confusion here about franchising, and actual sales).

Bottom line: ok so you removed Murco wall products material that probably contained asbestos. What now?

  1. Be sure that asbestos-suspect dust from prior demolition has been thoroughly cleaned-up.

    That means that all reasonable cleaning steps have been taken: damp wiping and HEPA vacuuming and if necessary, laundering or dry-cleaing of soft-goods.

    Watch out: do not use an ordinary household vacuum cleaner if you suspect there is asbestos dust present as those small particles will go right throug the vacuum cleaner and will be more airborne than ever- you'll increase any risk of breathing harmful dust (if in fact it's present, which we don't know).
  2. Should you have asbestos tests performed?

    Probably not but in any case, to get beyond arm-waving speculation and to base any health or economic decisions on fact, you'd need to hire an environmental professional.

    Watch out: do not hire someone simply to stop by to do a "test" (that approach of testing by itself is fundamentally flawed) for asbestos.

    Air testing for airborne particles has a use as a tool in the hands of an expert but such tests are fundamentally inaccurate even when the numbers given are very precise.

    An air test that says it found 193 particles of asbestos in air could be off by up to 4 orders of magnitude depending on how the test was conducted.

    So the "true" number might be less than 1 asbestos fiber per liter or cubic meter of air, or it might be 19 or 193 or 19,300 or 193,000 or 1,930,000 particles per cubic meter of air.

    Don't confuse precision ( a number with lots of digits or decimal places) with accuracy (is it actually close to reality?)

    Even if such a test suggests there's a hazard it's not prescriptive. You'd have to hire someone all over again to inspect and test enough to say what cleanup is needed. And beacause of the significant risk of a false negative, a test that says "no problem found" is usually not reliable.

    An expert would need to take a case history, inspect the building, decide what if any environmental testing would be useful, and to do that along with a written report of findings and advice about what further cleaning or other steps are justified and appropriate.

    It is not clear that such is needed, appropriate, nor useful, for the case you describe.

    To help decide on hiring someone for a more-careful inspection, see MOLD / ENVIRONMENTAL EXPERT, HIRE ? - when to hire an expert.

    If you want to do some low-cost "asbestos testing" to make yourself more-comfortable, You could use a surface vacuum test or tape test to see if an environmental test lab finds significant levels of harmful asbestos remaining in representative samples of house dust taken from horizontal surfaces in your home, choosing representative areas where you spend time, that have not been cleaned for a while and that might capture the "worst case" presence of harmful dust.

    This is not a quantitative approach but if, for example, a lab reported a significant level of asbestos in such a dust sample, the additional professional cleaning could be appropriate.

    Details are at TAPE & BULK SAMPLING & TESTS for MOLD
  3. Has My Family's Health Been Affected by Exposure to Asbestos-Dust from Murco ceiling paint or some other product?

    No one can offer a useful answer to that question as we have not one iota of data about your family member's level of exposure, duration of exposure, personal health history, nor any other health factors.

    In our OPINION, in some cases the anxiety over hazardous material exposure may itself have more-harmful health effects than the original exposure itself.

    Ask your doctor about your concerns and follow her advice. If she opines that further testing for asbestos-related health effects is warranted there are procedures that can be effective (in some cases).

On 2020-06-04 by (mod) - where to find lists of asbestos-producing companies and settlement trust funds

Gary,

Thank you for that helpful detail. Can you name the flooring products?

There have been class action lawsuits and various trust funds have been set up to give at least some financial support two people injured by asbestos exposure, especially workers.

If you need help finding those let me know and I will direct you.

You need to be able to name the company or companies where you worked and the years that you were there.
