Abstract

Highlights: The confined space fatality rate can be estimated to range between 0.05 and 0.08 per 100, 000 workers. No more than 17% of confined space deaths involve would-be rescuers. Confined space entrants are killed by atmospheric hazards and a range of physical hazards. Confined space rescuers are killed almost exclusively by atmospheric hazards. Abstract: Confined spaces are defined by a particular set of hazards which include oxygen deficiency, toxic airborne contaminants, flammable atmospheres, the risk of engulfment in free-flowing solids and liquids, and physical hazards such as working at heights, electricity, and moving parts and machinery. This study conducted an analysis of work-related traumatic fatal injuries involving confined spaces and compared the rate of confined space fatalities in the working population between similar industrialised countries; the rate of confined space entrant to confined space rescuer deaths; and identified the difference in the mechanism of incident between entrant and rescuer deaths. The confined space fatality rate can be estimated to vary between 0.05 and 0.08 deaths per 100, 000 workers, of which no more than 17% were found to be those undertaking rescue; with most of these deaths the result of hurried and ad hoc rescue attempts. While the major causes of death among entrants were toxic atmospheric hazards and physical hazards; confined space rescuer deaths were overwhelmingly as a result of toxic atmospheres. It is likely that these figures are an underestimate of all confined space fatalities, as government WHS authorities rarely identify such incidents as having occurred in a confined space. The inclusion of engulfment and other physical hazards of confined space work in safety legislation, and the separate identification of confined space incidents will permit better analysis and recommendations for confined space work safety improvements.
