Iceland's geographical isolation in the North Atlantic makes it one of the safest countries in World War 3 scenarios. It's politically neutral, avoiding military alliances. Iceland is self-sufficient in renewable energy, utilising geothermal and hydroelectric power.
Countries often considered the safest in the event of World War III include New Zealand, Bhutan, Iceland, Indonesia, and Switzerland, as well as certain parts of South America. These countries are known for being politically neutral, geographically isolated, self- sufficient, and having stable societies.
Iceland. Ranked number one since 2008, Iceland remains the world's most peaceful nation, leading across all three domains: safety and security, ongoing conflict and militarisation.

In sum, a nuclear blast IS survivable in this fridge, provided the fridge is 4.23km away from the blast . To survive the temperature effect of the blast, the fridge needs to be a mere 2km away – unsurprisingly the radiation exposure from a nuclear weapon is the principal concern.
Homeowners are generally prohibited from making alterations to the bomb shelter, including drilling into the shelter's walls. These regulations are outlined by the Singapore Civil Defence Force (SCDF), the authority responsible for civil defence matters, and the HDB which manages public housing.
