Besides, sensitive groups including children, the elderly and people with respiratory diseases should limit their time outdoors.

In case of going out, people should use PM2.5 dust-proof face mask which meets the standard and should travel by car or bus. In particular, pupils should not participate in outdoor activities.

When travelling on roads, people need to strictly follow traffic laws to reduce traffic congestion.

People should reduce activities that cause air pollution such as burning waste, cooking by charcoal stoves, transporting construction waste without shielding.

According to forecasts from the National Center for Hydro-Meteorological Forecast, weather conditions will not change much in the coming days, thus, it is expected that Hanoi’s air quality will maintain at this level.
