Fire can be especially dangerous when it occurs in hospitals because many patients in any typical hospital are not physically fit enough to quickly respond to emergency measures, especially evacuation calls. The present paper reports an in-depth assessment of the factors which have led to major fire accidents in Indian hospitals. The study reveals that several building safety codes, acts and guidelines are available, not only to prevent accidental fires but also to minimize harm when such fires do take place. However, observance of the stipulations is very lax, and seems to be exercised more in breach than in compliance. The study reveals that hospitals have zones like the intensive care units which are not only more prone to accidents than other zones but can also cause greater loss of lives due to the presence of critically ill patients, or persons who are extremely vulnerable (for instance newborn babies). Special codes and practices need to be framed for such zones. The study has also identified and catalogued a series of measures which must be implemented in future to prevent accidental fires in hospitals. The study is with reference to accidents that have occurred in India from 2010 to the present but is representative of the situation prevailing in most developing countries. [ABSTRACT FROM AUTHOR]

The summer monsoon circulation shows various spatial and temporal oscillations and often a combination of systems produces an integrated effect. In this study phases of the southwest (SW) monsoon have been identified in an objective manner with the help of T-mode principal component analysis (PCA) of weekly rainfall anomalies. Mean composite charts have been prepared utilising all available upper air data (1977-1986) for each category of the SW monsoon epochs identified by the PCA. These sets of charts have been constructed for both the strong and weak phases associated with the first four significant principal components (PCs). A well defined east-west oriented trough system, extending from about 28 deg. N Latitude/65 deg. E Longitude to 20 deg. N Latitude/90 deg. E Longitude, in the lower levels, has been themain feature associated with the strong phase of the monsoon corresponding to PC I. The trough in the lower levels is more marked in the eastern half compared to the western half in both the sets of charts associated with strong phases of the monsoon related to the PC II andPC III. With PC II, the position of the troughs in the lower levels is further north of its location in PC III. The east-west trough system associated with the strong phase of PC IV has a large southward tilt with height. The charts corresponding to the weak phases of these PCs have synoptic features, such as the position of the trough close to the foothills of the Himalayas, and the shifting of middle and upper tropospheric anticyclones to the south. The study suggests an objective method of interpretation of principal components by utilising synoptic data. In addition, synoptic models and data sets corresponding to different phases of the monsoon can also be prepared in an objective manner by such PCA. [ABSTRACT FROM AUTHOR]
