It is generally difficult to reliably determine the presence of asbestos based on appearance. If one absolutely needs to know, an analysis must be conducted. Otherwise, one can take "normal" precautions regardless (i.e., respiratory protection, gloves, and disposable clothing like overalls).

Ok.. had builders at home who tore up a carpet with asbestos in it. The lab could only determine that it was asbestos, but not which type. I read that Anthophyllite was common in asbestos paper. But it might have been different with the paper used under floor carpets.
The color of the paper was more towards white than gray. If that would now be an indication of chrysotile asbestos.[/QUOTE
Could be true, it's usually white with some gray tint.
    1. The Swedish Work Environment Authority has a detailed description regarding the presence and type of asbestos in different applications.

so most likely antofillite..
I assume that type of asbestos is more dangerous than the white one?

But does it matter? The protective equipment you need is the same regardless.

No idea about the degree of danger, I don't think either is beneficial. However, one shouldn't exaggerate the risk. I've personally both torn and laid mats with asbestos layers on a few occasions without special protective measures in the late '70s. So far, haven't noted any effects despite heavy cigarette smoking for many years up until the turn of the millennium.

I have personally both torn up and laid carpets with asbestos layers at times without special precautions during the late 70s. So far, I have not noticed any consequences despite massive cigarette smoking for many years until the turn of the millennium.

I understand... mostly worried about my children

Hi, I'm borrowing the thread to ask about my staircase from the basement. If there's anyone who can assess regarding asbestos, the carpet has been there since the house was built in '72.

One picture shows, as you can see, a step where one step still has the carpet and the other glue residues.

The other pictures are of the back of the carpet.

  • Close-up of the backside of a torn stair carpet, revealing fibrous material and adhesive residue, possibly containing asbestos from 1972.
  • Backside of a red carpet piece with fibers exposed, lying on a textured floor surface.

I assess it as a vinyl carpet with a textile or paper backing.
 
Looks like linoleum. Only an analysis can say for sure what it contains.

I read many who have received negative asbestos tests on exactly ? I recently discovered one like that in my house from the late 70s and am a bit suspicious.

Aha. I have read about some who have had this green backing which turned out to be asbestos-free. I will send in a similar one for testing myself when I get around to it. Does anyone know what material they used on the green ones?

What was your answer? Also read and seen a couple with the green backing where no one received confirmation that it contained asbestos, had a smaller piece/length that was left under and came along when we tore down a bookshelf. Color (and residues I guess) from the paper stuck in the concrete showed no asbestos, the carpet was already at the dump but I seem to remember it was more of a foam plastic. Typical Novilon carpet in a townhouse built in 1978.

In 1978 it was well known that asbestos was dangerous, and it had already been phased out in most products.
