Asbestos was used as early as the late 1800s through 1977 for building materials because it was very durable, heat resistant and noise absorbing. In the 1950s and 1960s it was THE thing. But in 1971 it was declared unsafe by the EPA, causing health hazards. The biggest problem (in my opinion) is that mastic (a kind of glue applied with a ridged trowel) contained asbestos. You cannot "sand" the ridges down when or if the tile or vinyl flooring (often also containing asbestos) is removed because the hazard occurs when the fibers become airborne.

Here is a highlighted section from the below referenced link.
THE BEST THING TO DO WITH ASBESTOS MATERIAL IN GOOD CONDITION IS TO LEAVE IT ALONE! Disturbing it may create a health hazard where none existed before. Read the referenced booklet before you have any asbestos material inspected, removed, or repaired.

Where Asbestos Hazards May Be Found In The Home

1. Some roofing and siding shingles are made of asbestos cement.
2. Houses built between 1930 and 1950 may have asbestos as insulation.
3. Asbestos may be present in textured paint and in patching compounds used on wall and ceiling joints. Their use was banned in 1977.
4. Artificial ashes and embers sold for use in gas-fired fireplaces may contain asbestos.
5. Older products such as stove-top pads may have some asbestos compounds.
6. Walls and floors around woodburning stoves may be protected with asbestos paper, millboard, or cement sheets.
7. Asbestos is found in some vinyl floor tiles and the backing on vinyl sheet flooring and adhesives.
8. Hot water and steam pipes in older houses may be coated with an asbestos material or covered with an asbestos blanket or tape.
9. Oil and coal furnaces and door gaskets may have asbestos insulation.
