F-51 A Study on the Way of Maintenance of Sanitary Environment in Medical Facilities : (Part 1) Outline of the Investigation and Legal Measurement Results on Indoor Air Environment

Abstract

It is important to maintain indoor air and sanitary environments in waiting lounges, office moms and medical wards of medical facilities. But Japan has no environmental and hygiene law for medical facilities. In this study, the way of the maintenance of sanitary environments in medical facilities was examined. This part reports the measurements of temperature, humidity, airflow rate, CO, CO_2, PM and formaldehyde concentrations in waiting lounges, office moms and medical wards of 9 medical facilities. As a result, humidity values in most part of the rooms were relatively low level. The CO_2 concentration in the waiting lounge that had a lot of out patients in that area was pretty high, therefore the capacity of the ventilating facilities might be exceeded.
