(iv)

This requirement is intended to protect water reactive chemicals from exposure to water in water based fire

suppression systems that may be used where flammable liquids are stored. Spraying water on a water reactive

material during an upset condition could increase the severity and danger of the upset condition. While not required,

consideration should be given to applying a similar restriction in oxidizer storage areas. See section 4.4.2.
