Using the language of your language lesson link, the phrase "such as" is telling us that a clothes closet is "included" in the list of places in which easily ignitable materials could be found. But that does not tell us that the panel is automatically considered to be "in the vicinity" of the clothes, simply by virtue of being in the same room. This rule is all about "vicinity." We can't put a panel in the vicinity of where clothes are stored. But we can, I submit, put one in the same room as a shelf full of clothes, so long as the panel is not "in the vicinity" of that shelf.
