I have an emergency staircase, which won't be used except in case of fire, and this staircase (core) is completely separate from the building's HVAC system, with an exhaust fan only, without any Air conditioning. The stairs flooring is intended to be granite, which is neither floor-score certified, nor guaranteed to be free from organic compounds. Now do I need to include this stairs to the IEQc4.3, or is it exempt, since that it's separate from the building interior? And if not, is it enough to get a suppliers MSDS stating that the manufactured granite is 100% mineral based, without any added organic compounds? Any help would be strongly appreciated

Mineral-based finish flooring products such as tile, masonry, terrazzo, and cut stone without integral organic-based coatings and sealants and unfinished/untreated solid wood flooring qualify for credit without any IAQ testing requirements. However, associated site-applied adhesives, grouts, finishes and sealers must be compliant for a mineral-based or unfinished/untreated solid wood flooring system to qualify for credit. -
