Appreciate the philosophy and terminology relating to the idea of risk
Part A Energy and non-energy threats

What is the energy source or non-energy threat with which we would characterise each of the following cases? Please note that the form an energy takes can (but does not always) change during an Occurrence, so that the form of the energy that is appropriate for this answer is the form appropriate to the Event itself. Read the notes to understand what this means. There are correct and incorrect answers. [3 marks each]

  1. An explosion occurs in a coal mine in New Zealand, trapping or killing 29 miners. Subsequent explosions lead to the mine being sealed without bodies being recovered. A month later the mine goes into receivership. Explosions in coal mines are not uncommon, as you’ll find if you look at web sources. Often the exact reason is not known but there are two common possibilities. One is that the process of mining may penetrate pockets of hydrocarbon gas. The other is that the process creates coal dust.
  1. A light aircraft hit a power line when on final approach to the end of the runway at Geelong airfield. The contact with the power line decelerated the plane to such an extent that it hit the road and then the road-side embankment of the main road that also runs along the airfield boundary. Remarkably, the two people on the plane escaped and ran away before the plane burst into flames. The power line was broken and interrupted the power supply to Torquay and a number of other small communities. This interruption lasted at least four hours. Power lines were lying on the road so one carriageway of the road was closed for some hours while they were removed. The burning wreckage of the plane also closed the other carriageway. The plane actually hit the carriageway in a 100km/hr zone and it is surprising that vehicles on the road were not directly affected.
  1. A sick woman was being transferred from a cruise ship to another vessel for emergency medical treatment when she fell into the sea. This was in the very cold North Sea. The woman later died in hospital, apparently largely as a result of the exposure to the cold water.
  2. A suspension bridge collapses, apparently when a suspension cable breaks. A number of people and vehicles fall from the bridge into the river, where some 11 people die due to drowning.
5.A couple were walking along a beach beneath a cliff, part of which collapsed and buried them.

  1. A building (the Rana Plaza, in Bangladesh) housing a clothing factory collapsed killing some 1100 people.
  2. A Japanese factory worker allegedly poisoned frozen fish food with pesticides. At least 2483 people complained of illness after eating foods.
  1. A large fire burns at an open cut coal mine near Melbourne, apparently ignited by a nearby grass and forest fire lit by arsonists. Smoke envelops the nearby town of Morwell and results in significant deterioration of the air quality, such that evacuation was considered at one stage. The owners of the old mine and the nearby power station had apparently removed water pipes placed there for possible future fire fighting.
  1. A wild life park keeper was killed by a tiger when she was working in the cage. The tiger was supposed to be contained within a cage itself within the cage being worked on. Systems were said to be in place to ensure that keepers and animals were kept apart at all times. A bolt on top of one of the internal doors was found to be defective, in that it was unable to secure the door.
  • A mine tailings dam in Brazil, owned by BHP Billiton and VVale, fails, leading to widespread destruction and loss of life.
