Disaster planning is a task which will probably never be "completed", since to be effective, a disaster plan must constantly be reviewed and modified. The Hospital Disaster Working Committee at the Ottawa General Hospital has so far been presented with both challenge and opportunity. The challenge is to make best use of our new facility, while coping with the changes which a new site predicates. The opportunity is to take advantage of the past experience of our own people and others who are involved in disaster planning, and make a strong beginning.
