ACIDIC GAS CLOUD ENGULFS UK SKIES
Brits have been warned to stay inside as a cloud of corrosive and acidic gas, which can cause serious health problems, covered the UK.
Weather maps showed a massive cloud of sulfur dioxide (SO2), spat out by the recent volcanic eruptions in Iceland, completely covering the country.
SO2 is predominantly produced from the combustion of coal or crude oil, but volcanoes also produce vast quantities of it when they erupt.
Inhaling the gas can cause symptoms such as a sore throat, coughing, a runny nose, burning eyes, tight lungs, and difficulty breathing.

It is a colorless gas, so see-ing it is not how one would identify it. The main identifiable characteristic is that it smells pungent - not like rotten eggs, but like burnt matches - basically - as soon as the gas hits one's nostrils it stings the mucus membranes.
