The "risk of explosion" symbol, an inverted trangle containing an image of an apparently circular object exploding, with half the object disnintegrating into small chunks that are being propelled to the right and up. There are thin triangular wedges emanating from the object, to suggest projectile motion and perhaps force. Next to the symbol, all of the bits of the object have been reassembled to show that the sum total is greater than the circle suggested in the original picture.
