Vietnam: Severe air pollution to continue in Hanoi through at least Nov. 13

Event

Air pollution is affecting portions of Hanoi since Nov. 3. Authorities have blamed rice field burning after the harvest season as the main driver of the worsening air pollution. Vehicle emissions, construction activities, and operation of industrial areas also contribute to air pollution. The poor air quality is forecast to persist through at least Nov. 13.

Flight disruptions are possible at airports in the vicinity, including but not limited to Noi Bai International Airport (HAN). Flight delays are especially likely overnight and during early mornings when relative humidity is high. Officials may also close sections of roadways and require trains to travel at slower speeds in some areas until air quality improves.

Advice

Observe local air quality index reports. Plan for possible business and transport disruptions. Confirm all transport reservations, especially flights at HAN. Drive cautiously, and allow extra time to reach destinations due to low visibility and road congestion. People with certain underlying high-risk conditions - such as asthma, chronic obstructive pulmonary disease, or heart and lung disease - could have adverse reactions to poor air conditions in affected areas. Individuals with such conditions should have adequate medication on hand and consult with a physician. Concerned individuals should limit the amount of time spent outdoors during periods of poor air quality. Revisit contingency plans, including telecommuting options, in the event of significant air pollution.
