<br />QyLc k Rejerence, Guideline:
<br />At, present, indoor air quality regulatory limits do not exist apart from OS,H,A's, Permissible
<br />Exposure Limits (PEL which were developed for traditional industrial environments and are not
<br />a, suitabilic =as= of good, indoor air quality., The following guidelines have generally been
<br />adopted by the practitioners of'indoloir air quality.,
<br />Carbon Dioxide (C'02)
<br />Generally, the number of reported air quality co is tends, to, increase as the CO2 levels
<br />climb past 1,000 ppm. A rough upp,er-lit of 1,000 ppm is used as the ideline. If CO2
<br />gul
<br />levels significantly exceed 1,,000 ppm in occupied areas, some toe ofcorrective action
<br />should, be perfonncd, to iuprov,e air exchange.
<br />It Car on, Monoxide ('C►,)
<br />A guidelime referenced in the American, Society of Heating, Refrigerating, and Air-,
<br />Conditioning Engineers (ASI 'HRAE) Standard 612-1999, is the National Ambient Air, Quality
<br />Standard, of 9 ppirn for an 8-hour exposure., Headacbes, nausea, and ess can be reported
<br />when CO levels approach and exceed 10 pip m. In non-industrial indoor environments, a CO
<br />level off'' 5 ppm, is considered significant and additionally investigation is warranted.
<br /># Discussion of Results
<br />Carbon dioxide,, c bon monoxide, relative humidity and temperature levels were
<br />within indoor air quality guidelines.
