An original cause of drowning in an industrial environment

Investigation of Drowning Deaths: A Practical Review

Drowning, which typically involves a watery environment, remains a serious public health concern claiming an estimated 362 000 lives per year worldwide across all socioeconomic classifications and has remained under close observation by the World Health Organization and its signatories. A significant number of water-related deaths are attributed to accidental drowning, while a smaller but still significant number represent suicidal or homicidal drowning. Others involve a combination of drowning precipitated by injury, intoxication, or environmental extremes. Still others involve victims that die from injury, intoxication, or a natural disease entity of such significance as to preclude the drowning process, while near or in water. While there may be an initial presumption that all water-related deaths are accidental drownings, other possibilities must be considered in the investigation of these types of deaths, as drowning as a cause of death is a diagnosis based on the exclusion of other potential causes. The coordinated investigative efforts of multiple agencies and disciplines are required not only for the designation as drowning as the cause of death but also for death certification. The ongoing analysis and dissemination of data generated from all levels of investigation augment our understanding of the impact on public health and safety, guiding allocation of monetary and educational resources in an effort to prevent further mortality and disability.

Quenching tank: Accidental drowning in hot quenching oil

We describe an unusual case of drowning in fluid other than water in an industrial setting. A 26-year-old man was working in an industry which performs surface treatment of mechanical steel parts with quenching oil. He fell into the quenching oil (which was hot due to immersion of red hot metal parts), and as he was working alone in the particular section, there was a fatal outcome. A medico-legal autopsy was performed. The causes of death were found to be multiple, with the association of drowning, extensive superficial burns and asphyxia due to laryngeal oedema. To our knowledge, it is the first report of drowning in hot quenching oil, and only nine previous observations of drowning in industrial environments have been reported in the international literature. Even though rare, these kinds of accidental deaths can be prevented in dangerous industries with proper precautions and strict adherence to standard operating procedures.

Unique drowning in an atypical medium: paraffin wax in the setting of a motor vehicle crash--case report and literature survey

Among the various modes of death due to asphyxiation, drowning is unique. Unlike other types of suffocation associated with occluding airway obstructions (i.e. choking and smothering); with drowning, there is typically filling and involvement of the majority of the tracheobronchial tree and aerodigstive tract. Although the usual drowning medium is water, it can also occur in other media. Moreover, although drowning sometimes occurs in the setting of a motor vehicle accident, an element of vehicular submersion or immersion is usually operative in such instances. The case presented here is that of a motor vehicle crash which resulted in drowning where no immersion of the vehicle occurred. Moreover, the drowning medium was paraffin wax, rather than water. Other cases in the literature of drowning in atypical media and also those which are reported in the concomitant presence of a motor vehicle accident are presented.
