Danger!: “Catches fire”
Cause/Consequence: “It catches fire, it melts, and only thin pieces cut. This is the #1 material that causes laser fires!!! (Commonly known as Foam Core board) Also known as the white foam that cups and coolers are made of, or the Pink and Blue Sheets found at the hardware store.”
