Development of New Diagnosis and Treatment Facilities for Chemical Sensitivity: Construction of Full-scale Model Room and Evaluation of Air Cleanliness

Abstract

The purpose of this study is establishment of reducing contaminant concentrations upon the construction of new diagnosis and treatment facilities of Chemical Sensitivity. In this paper we describe the results of a full-scale model experiment, which was conducted in a model room constructed at the Shinryo Corporation Research & Development Center before the construction of diagnosis and treatment facilities.Firstly we proposed new construction materials selected and/or developed for the present facilities. Secondly we designed and proposed a new HVAC system adapted for them. These facilities are equipped with special activated carbon (SAC) filter, a special outgas-free air handling unit/blower, degreasing of metallic components, no-binder HEPA filter and inorganic joint sealant. In addition both new chemical concentration monitoring and control system were developed for the new facilities. Finally cleanliness assessment of the model room was conducted by using Non-Methane Hydro Carbons (NMHC), Volatile Organic Compounds (VOCs) and particulate matter (PM). It was indicated that concentration levels of all three subject materials were extremely low in a model room and the present proposals were usable for the construction of new diagnosis and treatment facilities of Chemical Sensitivity.
