Case study on Indoor Air Quality of public offices at RIL, Jamnagar

Introduction
Reliance Industries Limited Jamnagar is a petrochemical plant. The Public offices & control rooms are part of the industry. Indoor Air Quality (IAQ) is important element of occupational health. Office buildings are common sites of indoor air quality problems. The objective of IAQ measurement is to identify the concentration of contaminants which create significant health risk because poor IAQ can lead to a health problems and potentially affect to comfort, concentration and performances of employees. 

Methods
During a detailed assessment of an indoor environment, air quality investigated and measured at 4 buildings and 9 control rooms at RIL, Jamnagar from Jan 2010 to Dec 2010. There are two approaches in assessing indoor air quality: indoor air quality monitoring with qualitative exposure assessment and quantitative exposure assessment.

Results
The measurements were performed in public offices and parameters measured were carbon dioxide (CO2) concentration, Relative Humidity, Temperature, Cubic Feet Per Minute, Illumination, printer power concentration, Air Changes Per Hour. Reported data indicate that the levels of all the parameters in all the offices are within the standard limit (ASHRAE), ACGIH & Indian Standard.

Discussion
The most indoor environmental problems can be prevented or corrected easily and inexpensively through the awareness program and monitoring of indoor air quality. Developing a site- specific sampling and analysis plan, providing basics of IAQ to eliminate problems and identifying the building related health symptoms should be a major focus to improve the standard of health of our employees
