Congoleum asbestos flooring identification: this article provides a guide to identifying Congoleum-Nairn asphalt-asbestos, vinyl asbestos floor tiles, linoleum, and sheet flooring (resilient flooring) materials that are reported to contain asbestos, or that have been confirmed as containing asbestos in asbestos fiber or asbestos powder-filler form.

Asbestos is safe and legal to remain in homes or public buildings as long as the asbestos materials are in good condition and the asbestos can not be released into the air.

Congoleum Sheet Flooring Products Resembling Individual Floor Tiles
At above left is a continuous resilient Congoleum Nairn sheet flooring product that was colored to resemble individual floor tiles in red, black,and white The Congoleum-Nairn company advertised that this approach was less costly and quicker to install than tiles, and permitted better control over tile color consistency.
Above right our photograph excerpted from another 1950's flooring advertisement shows a Congoleum sheet floor used in a kitchen and dining area.

Congoleum Gold Seal Sheet Flooring ca 1950: test indicated No Asbestos Content
While certainly there were Congoleum flooring products that did not contain asbestos, without testing or other information, to be safest I would treat the material as presumed-asbestos-containing material (PACM), and while no one can guess at an environmental hazard just from a brief email description, from your description it sounds as if you've handled the matter correctly and that the amount of dust released of any sort would have been trivial.
In particular, a sheet flooring that was not glued down is usually easily removable in large pieces without breakage and dust other than the accumulated dirt and dust debris that accumulates in old building layers and materials.

Here is an update on the Congoleum I found under the bathroom floor: just got the results tonight from Western Analytical Lab and there is NO asbestos in the sample I sent them! We are very relieved!
