How to Identify Asbestos Ceiling Tiles

Asbestos was widely used in home construction until the 1970s when the substance was positively identified as a major health risk by the government. Construction materials that used asbestos were used both inside and outside of the home. Its use was at a peak during the 1950s, and estimates claim that as many as half of the multi-storied buildings constructed from the 50s through 70s have some sort of sprayed-on material that contains asbestos. Identifying ceiling tiles that contain asbestos cannot be done solely on sight alone. However, using age and a few additional tips and tests, the composition of the tiles can be identified.

Instructions

  1. Identifying Suspect Ceiling Tiles

    • 1

      Research the building history. Buildings constructed after the mid 1970s are unlikely to contain asbestos ceiling tiles.

    • 2

      Put on protective gear. Asbestos is a toxic substance that is easily inhaled and should not be allowed to come into contact with the skin. Be sure to cover all exposed areas as much as possible.

    • 3

      Identify ceiling tiles that may contain asbestos. Tiles that were hung during the late 1940s and later that are approximately one square foot and have an off-white, yellowish, or light gray color and have a fairly solid or evenly perforated surface are the most likely to contain asbestos.

    • 4

      Avoid touching, scraping, cutting or otherwise disturbing the suspect tiles. Doing so may release asbestos into the air and put people at risk of exposure.

    • 5

      Turn off any heating or cooling systems that run through the area in question.

    • 6

      Limit access to the area and contact the EPA for a list of certified asbestos inspectors in your area.

    • 7

      Make an appointment for a professional inspector to visit the site and perform the proper tests to determine whether or not the ceiling tiles contain asbestos.
