Example:
The Health, Flammability, Reactivity and Other parameters are all optional. Use only the ones that are appropriate for the situation. Typically, the Blue, Red and Yellow sections will be filled in, as a minimum; if the hazard is not relevant, or it is known that there is no hazard in a category, assign a code of "0".

* 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: <strike>W</strike>) are NFPA approved symbols, although various iconic graphics are in common use to denote acid, alkali, corrosive, radiation, poison and explosive hazards.
