Abstract
This paper discusses the key findings of an indoor air quality (IAQ) audit to assess the IAQ status of the offices within a printing factory. Various objective and subjective measurements to co-related the employees' perception of the physiological and physical parameters were carried out. The objective measurements covered the chemical, physical and biological contaminants, and tracer gas tests for possible cross-contamination. The closest available local ENV 1996 guidelines were used to benchmark the performance standards. The study shows the high concentration levels of Total Volatile Organic Compounds (TVOCs) and formaldehyde (HCHO) were observed at all sampling locations, with indoor to outdoor ratio of greater than 2. This indicates a strong indoor generating source of TVOCs and HCHO. It is not surprising since the building uses substantial quantities of solvents in their daily operations coupled with an ineffective ACMV system and layout of the production spaces.
