With F/S 2 materials, however, the added hazard of fragmentation (the rapid release, or explosion, of hot metal pieces in all directions) also is present. As such, the atom is the basic building block of chemistry. Previously, it would have denoted any toxic hazard, whereas, with the introduction of the health hazard symbol, it now refers strictly to substances with acute toxicity.
