Caitríona Redmond: Could you survive 72 hours in an emergency?

The EU recommends that we have fully-charged power banks for mobile devices and torches. And Milton liquid is a relative cheap disinfectant to have to hand.

We are all familiar with a water filter jug or tap which improves water flavour and can filter some impurities. A straw filter which is a portable water filter system which uses hollow fibre membrane technology to clean water-borne diseases and dirt.
My favourite brand is the Life Straw due to their proven results and international charity work. One Life Straw will filter up to 2,000 litres of clean water and reduces the need to store water in plastic bottles.
A damp box of matches is useless and stick lighters can run out of fluid. Consider investing in a fire steel or rod instead. These sticks are made from magnesium ferrocerium and will spark in all weathers, including in a downpour. Both items can be purchased from your local camping stores or online.
