NFPA 704 four-colored diamond Health 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. E.g. chloroform Flammability 0: Will not burn. E.g. water Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
Chelation of a metal cation by triphosphate.
The eutrophication of the Potomac River , caused from phosphate run-off, is evident from the bright green bloom of algae .
