Beijing’s choking smog hits red-alert level for first time ever as schools and factories are forced to close

Beijing issued its first red alert for smog on Monday night as the capital was hit by hazardous levels of pollution for the second time within a week.

The alert – the highest in a four-level system – will be in place from 7am on Tuesday until noon on Thursday.

Beijing has ordered primary and secondary schools to close and recommended government departments, public institutions and companies to implement flexible working hours.

It means traffic will be heavily controlled. Car usage will be limited based on the last number of the vehicle’s licence plate – odd and even numbers will be allowed on the roads on alternate days. Government departments will be required to reduce car usage by 30 per cent.

Public transport will run on extended timetables, while heavy construction trucks will be banned from the road.

All outdoor construction will be suspended and factories will be required to close for two days or face operating restrictions.

Firework displays and barbecues are also prohibited.

The smog is expected to reach its highest level on Wednesday.
