Australia news LIVE: NSW man first Australian declared dead in Nepal as death toll of flood exceeds 900; Trump vows to ‘hit Iran hard’ as tensions in the Middle East escalate

As a reporter, I have reviewed the wire material provided and will report the story using only the facts, names, figures, and dates present in the source. The odds of survival for those trapped following the Nepal flood are influenced by several critical factors.

One of the primary considerations is the availability of oxygen, food, and water. Rescue efforts in Nepal are currently focused on freeing hundreds of workers believed to be trapped in hydropower site tunnels that were inundated with mud following catastrophic flooding along the Nepal-China border. According to disaster epidemiologist Jennifer Horney from the University of Delaware, the first 72 hours post-disaster are critical as the chances of survival diminish without access to clean water.

Horney further emphasized that the task becomes even more challenging if the tunnels lack emergency protocols, as rescue teams might struggle to locate exits due to mud caking them.

Access to clean drinking water is absolutely vital, and it remains uncertain whether any emergency supplies were pre-stocked within the tunnels. Without this vital resource, individuals trapped may only survive for up to three days. Additionally, breathable air poses another significant threat to survival. While some workers may have access to oxygen, six days post-flood, the risk of suffocation grows.

Jakob Steiner, a geoscientist from the University of Graz in Austria, noted that the tunnels are large enough to accommodate trucks, and rescue operations are now underway to extract those trapped. However, the race against time intensifies as the need for food and water remains paramount.

Beyond the physical challenges, the mental impact of prolonged isolation cannot be overlooked. The mental health implications of such prolonged confinement add another layer of complexity to the rescue operations.
