The fault tree expert system SAFETY FIRST was developed to identify safety problems that may result in a fall accident and investigate the causes of a fall accident that has already occurred. The first major tasks in the development of the system was to acquire the knowledge which would be needed regarding the causes of construction falls. Experts in the field of construction safety were interviewed and searches were made of all available literature. It was determined that unintentional falls resulted from seven major elevated components: floor edges, floor openings, roofs, wall openings, tops of walls, steel beams, and portable ladders. There were also six major types of scaffoldings identified for analyses: form, tube and coupler, suspended, wood pole, tubular welded, and mobile scaffoldings. The causes of falls from the same level and slips were also determined. The causes of falls were classified into two major groups: basic causes which may directly induce a fall (enabling, triggering, or support related problems), or conditioning causes whose occurrence make a fall more likely to happen, such as safety problems.
