Abstract
In response to a request from the American Federation of Governmental Employees, an investigation was undertaken of possible hazardous working conditions at the Social Security Administration office (SIC-9441) located in Petersburg, Virginia. Concern was expressed regarding high humidity levels, breathing problems, burning eyes, and a lack of air conditioning. Based on a visual inspection of the air conditioning and heating system, increased maintenance was needed. An abundance of visible microbiological growth was noted on the interior of the air handling unit (AHU) mixed air plenum, and the pneumatic linkage for the return air damper was disconnected. An abundance of fungi and bacteria were noted in the analysis of bulk material samples collected from the AHU mixed air plenum. In some cases the measured airflow volume was less than 50% of the adjacent slot diffusers, indicating the air distribution was not balanced, perhaps resulting in the comfort complaints. Temperature measurements exceeded suggested comfort ranges for winter months. Some carbon-dioxide (124389) measurements exceeded the 1,000 parts per million ceiling recommendation. The author concludes that there were significant deficiencies in the indoor environment that may be related to reported symptoms and comfort complaints. The author recommends that improvements be made in the ventilation system, and that a system maintenance program be implemented.
