Beijing- Orange Air

Beijing raises pollution alert to orange for first time as heavy smog blankets capital — RT News: "Beijing raised its four-tiered smog alert system to 'orange' for the first time on Friday as heavy smog was forecast to roll into the city for the next three days. Officials have urged people to stay indoors and use public transport.

When Beijing’s Air Quality Index (AQI) readings went above 300 micrograms per cubic meter on Friday – more than ten times the level considered safe by the World Health Organization (WHO) – the orange warning level was brought into effect.

The category, which is the second-highest after 'red,' advises schools to cancel outside sports classes and states that children and elderly should stay indoors. Residents are also advised to leave their cars at home. The 'orange' alert falls short of ordering schools to close and prohibiting government vehicles from using the roads – those provisions come into force under the red alert."
