Notes:

. Similar Iow-IeveI/within range readings outside of the building.

. No Permissible Exposure Level (PEL) for Oxygen but readings fall within acceptable
range for regulations for atmospheric hazards in a confined space).

. American Industrial Hygiene Association (AIHA) considers 5 VOC as "within
range" for indoor air.
