Antarctica is the coldest place on the earth
Antarctica holds the record for being the coldest place on Earth, which together with extensive ice cover and lack of winter sunlight makes the continent pretty inhospitable to life. The sea, rather than the land, is what supports most creatures such as penguins and seals. It's often warmer than the land, so is a good place to retreat to and warm up to a balmy -2 Celsius. Permanently land-living plants and animals in Antarctica are small and ground-hugging to avoid wind chill and the accompanying dehydration.
CRN is a number system in Canada in which the number is issued by each province/territory of Canada to the design of pressure-containing equipment. This numbering system recognizes that design has been approved and registered for use under that province/territory. All boilers, pressure vessels, piping, tracing, hoses, and industrial instrumentation fall under this requirement. Know more about CRN Canada and JMengineering.ca
