Possible asbestos in pipe joint


I found some joints that may contain asbestos. Please, take a look at these pictures:

I suspect these fibers have been used there:

They have a yellowish color although they appear white in the photo. Do you think they’re asbestos? What other material could it be?

From your pics it appears to be this

Yes, it’s Oakum.

Irrelevent of what it is suspected to be, the only way to determine if it contains asbestos is to have a sample tested in a Certified Lab… and with that being said, my opinion is that yes it is Oakum, and no it typically does not contain asbesteos… but it could!

And what is the issue with it if it were?
