Abstract

In the present scenario medical waste produced in health care is a special kind of waste which causes for several possible health and safety hazards to the public and environment, if inadequately treated. In general the bio-medical wastes in hospitals are accumulated everyday which is to be properly disposed or incinerated so that it won't cause pollution and harmful effects to the society. This should be carried out within the working hours every day without any delay, but there is an undesired event of time delay in the collection of BMW. The aim of this research is to identify the events which are highly influencing the time delay in BMW management in a private multi-specialty hospital, Chennai. The fault tree analysis method is used to trace out the events, which could contribute for the delay in BMW collection and it focuses on the qualitative and quantitative aspects. Finally, all the basic events were ranked based on their effects on the undesired top event related to time delay using Birnbaum's importance measures. It was found that there are ten basic factors having higher contribution over the time delay and these factors should be prevented or eliminated to avoid the time delay during BMW collection.
