I have basement ceiling tiles that are about 12 inches square, without

need to remove a tile. How can I do this safely?

I can't tell what holds the tiles in place. The tile is made out of a
white fiber-like substance, with lots of holes, most likely to absorb
sound. Can I just pry around the edges?

Thanks!
Hmm,
Hope your access target is near the wall. Most likely they are T&G tiles
stapled to the strapping above.
