Recently I saw a documentary about asbestos and it freaked me out a little. The reason is that in 2012 some friends and I visited an old and abandoned amusement park to do an airsoft battle. At the time, I didn't really worry about asbestos. But after watching the documentary I rewatched my GoPro footage of that day and wondered if I came into contact with asbestos.

Following is a screenshot of some ceiling tiles that were laying over there. There are markings on the back but they are incomplete. Could those contain asbestos?

Nope: That's modern drywall (a.k.a. gypsum board, a.k.a. Sheetrock).

I don't think the ceiling tiles are sheetrock, but my answer is effectively the same that it's probably not dangerous.

It appears to be tegular (having a rabbet cut around the edge) ceiling tiles manufactured by Armstrong in a year where laser imprinting of the backs of the tiles was possible. 03/03 date on one of them might be day and month or month and year, but in any case they are highly unlikely to contain asbestos.

From their FAQ: 2 - What do your mineral fibre tiles consist of? Our mineral fibre tiles are made from a combination of the following naturally occuring, processed and recycled materials in varying proportions depending upon the tile type: mineral wool, clay, perlite, cellulose and starch mixed together in a water based process before being cured by heat. They are then finished with a water based paint, or laminated scrim and paint, decorative facing. All these materials are environmentally safe and our factories comply with ISO 14001. Note: Asbestos, in any form, is not and never has been used in the manufacture of Armstrong ceiling tiles.

  • Thanks for your reply! I'm glad I don't have to worry about this. – karlo Jun 20 '17 at 23:07
