Thailand: Authorities warn of severe air pollution in Bangkok through at least Feb. 3 /update 1

Event

Severe air pollution is forecast to continue to impact Bangkok through at least Feb. 3. Authorities have recorded unhealthy levels of PM2.5 particles across multiple districts in the city over recent days and authorities have warned that further high levels are likely over the coming days due to stagnant air and agricultural burn off from areas downwind of the capital. Bangkok Governor Chadchart Sittipunt has urged residents to work from home if possible and to limit exposure by reducing outdoor activities and wearing face masks.

Business and transport disruptions may occur. Shipping and supply chain delays are possible, especially for time-sensitive deliveries. Air pollution could result in reduced visibility. Flight disruptions are possible at airports in the area, including Don Mueang Airport (DMK) and Suvarnabhumi Airport (BKK). Flight delays are especially likely overnight and during early mornings when relative humidity is high. Officials may close sections of roadways and require trains to travel slower 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 DMK and BKK. 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.
