What is the main danger at Scott Base and why?

Fire is the main danger because water is a very precious commodity in Antarctica. All visitors to Scott Base receive instruction on procedures should fire break out. All winter-over staff have an intensive two weeks of fire training before travelling to Antarctica.  Regular fire drills are held and the alarm can sound at any time. A Fire Chief is responsible for a carefully selected fire fighting team. In the past 50 years there have been occasional fires but nothing serious.
