Abstract
Destabilized elemental phosphorus, for example resulting from fire involvement due to exposure with air, can be treated by placing the destabilized elemental phosphorus in the presence of a weakly basic aqueous solution of an alkali metal hypochlorite as a blanketing agent. Sodium hypochlorite is preferred.
