* Prior to 1996, this section was titled "Reactivity". In current NFPA literature the yellow section is called "Instability".
** Only OX (markup: OX) and W (markup: <s>W</s>) are NFPA approved symbols, although various iconic graphics are in common use to denote acid, alkali, corrosive, radiation, poison and explosive hazards.
***When you use both OX and W, use OX, W (markup: <small>OX, <s>W</s></small>).
