What is under my floor
Asbestos was identified in the 70’s as a health concern by the late 80’s it had strict regulations for inspecting and removal although the EPA ban in the US &amp; many other countries also banned asbestos. Asbestos was still legal into the early 90’s in some areas if you are concerned have the material tested. Color of a material is not an indication if it has asbestos.

With all that said most contractors quit using asbestos based products prior to the mid 80’s due to lawsuits, but testing is the only way to know with certainty.
