Since you believe "preserve" and "kept safe" refer to multiple objects, why do you not argue for the preservation and safe keeping of the furnace in vs. 6?
The word "preserve" has only one meaning, which is, preserve, or somewhat synonymously, keep.
Where the multiplicity comes in is in the object, the "them". That is, whether it is the general or the specific. The general means the general truth of the psalm (as you interpret it); the specific is the prophetic interpretation of the psalm when those things come to pass as described in verses 1 to 5 (and 8 ). Even the specific time references "now" and "when" are used to indicate a specific moment/period in history.
The way to understand the Bible is not by mere proximity in syntax, as leads to your suggestion of "furnace"; but rather, that there is obviously a clear conceptual construct in the passage. Besides, grammatically, the furnace is singular, not a plural "them".

One could argue that the English rules of proximity would point to the furnace instead.
That is a postmodernistic argument, that one could argue anything, everything, nothing or something unknown. But the spiritual approach is to see structure, rigidity/consistency, and well defined bounds. Thus, the word "furnace" should no more be accepted as "them", than a willy-nilly of speculative, imaginative interpretations.

... for that matter, if these verbs could address multiple objects... why stopnat 2, 3 or 4... just pick any object in the text.
That is the usual argument of the singularist view (the other being the reference to the hyper-allegorical method). They dismiss the tight, specific structure of the fulfilments and their relationship, but suggest that it is not restricted and orderly, but that it is, or might be, a free-for-all.
Once again, let us think about the non-muzzling of the ox. God spoke by Moses in agricultural terms, which was indicating a higher principle, viz., that godly folks should care for their animals; so likewise, in Paul's higher, fuller interpretation, God was really saying, look after your ministers.
Did Paul then also say that the "ox" could represent Christ's humanity and his earthly ministry? That is, after all, a possible "hyper-allegorical" interpretation. But Paul did not say it. So then, we see that there is a strict boundary on interpretations, which disallows intrusion of other ideas other than what the Holy Ghost intended, and clearly a double sense, multiple sense, germinancy and/or fuller sense (sensus plenior) are possible.
I advocate multiple fulfilments, see my book on the subject, at
www.bibleprotector.com/prophecy But I do not advocate random, numerous, subjective, "private interpretation" fulfilments.
