There are no rules for predicting which prepositions will occur before or after a particular noun in idioms such as those listed.

We can observe, however, that the initial prepositions come from a larger set (at, by, for, in, on, under, or with) than the prepositions that occur after the noun (of, to, or with).

These constructions are followed by an NP, which may be simply a head noun, as in 1a), or a head noun with one or more modifiers, as is the case in 1b), 1c), and 1d).

All of these idiomatic structures still involve a basic prepositional phrase structure. At least two analyses of these structures are possible.

We will adopt the one shown in 2), in which in case of is considered to be a complex preposition composed of more than one word, followed by the object NP, in this case, the noun fire.
