I am getting ready to paint a bathroom in a 1960's house. Prior to
doing so I want to replace the old ceramic baseboards with oak. Should
I gingerly pop one off and have the adhesive tested for asbestos prior
to pulling them all off? I had a look at one a few years ago, and it
was a light brown colored adhesive.

Here is a photo of the tiles I am talking about, to give you an idea.
