Snow affects Beijing travel (2)

Flight operations at the airport of Jinan were affected on Thursday evening but were restored on Friday.

Beijing started to use environmentally friendly snowmelt agent on some major road sections on Friday, according to the capital's municipal affairs administration commission.

The liquid agent contains no pollutants such as chloride, sulfate or nitrite, so will not affect the road surface and plants by the wayside.

Nevertheless, the commission said it will try to limit usage of the snowmelt agent and avoid it entirely in areas including Tian'anmen Square, residential areas and parks.

The snowfall ended on Friday afternoon. But at 4 p.m., the Beijing Meteorological Station released an orange warning on fog and a yellow icy-road warning.

China has a four-tier color-coded weather warning system: red, orange, yellow and blue. Red is the most serious level.
