If the PSI exceeds 200, N95 masks will be distributed to eligible Singaporeans, while air-conditioned haze shelters at community clubs, as well as selected residents’ committee and residents’ network centres, will be set up.
Preschools must stop outdoor and strenuous indoor activities when air quality is Very Unhealthy, while outdoor sporting activities may be modified or suspended. Employers have also been advised to limit outdoor work.
Schools may be closed if the next day’s 24-hour PSI is forecast to exceed 300 and enter the Hazardous range.
The haze comes as the Formula 1 Singapore Grand Prix weekend continues at Marina Bay, with the first sprint race in Singapore taking place on Saturday. Organisers have said contingency measures are in place should air quality worsen.
