Singapore Grand Prix has haze contingency plans as air quality turns unhealthy
Officials say masks, medical help and updates could be provided at the Marina Bay Street Circuit if needed, while decisions on any event changes will depend on conditions.
Singapore has contingency plans for the 9–11 October Formula 1 Grand Prix at the Marina Bay Street Circuit after air quality reached unhealthy levels, the Singapore Tourism Board said on Thursday, 8 October. The plans include keeping people at the circuit informed and making N95 masks and medical assistance available if required. Officials said any decision to change the event would depend on the haze's effects on visibility, health or operations.
The plans cover different levels of the 24-hour Pollutant Standards Index, or PSI, and one-hour readings of PM2.5, fine airborne particles. STB said government agencies are working with race promoter Singapore GP on the health and safety of those involved in the race and its entertainment programme. It did not say that masks had already been distributed or that an event restriction had taken effect.
What could change at the Singapore Grand Prix
STB said the relevant agencies would assess any haze-related visibility, public-health or operational problems with Singapore GP before making collective decisions about the event. Its action plans depend on how intense the haze becomes. The board said it was monitoring conditions with the inter-agency haze task force led by the National Environment Agency, or NEA.
The Federation Internationale de l'Automobile, motor racing's governing body, said earlier on Thursday that worsening haze could lead to some restrictions on outdoor activities, including entertainment, according to CNA. The FIA did not expect the race itself to be affected. That assessment does not rule out a later decision if conditions change; STB said agencies and the promoter would weigh any actual problems together.
For spectators and others at the circuit, the confirmed measures are preparations tied to air-quality levels, rather than a fixed change to the race schedule. STB identified information about the latest haze developments, medical assistance and N95 masks as measures that could be used if required. It gave no threshold in the reported statement at which any particular measure or event change would automatically follow.
What Singapore's air-quality readings show
NEA's 7 October advisory recorded a 24-hour PSI of 105 to 140 at 6pm, within the unhealthy range, and one-hour PM2.5 concentrations of 71 to 136 micrograms per cubic metre, in its elevated band. The agency forecast that the 24-hour PSI would remain in the unhealthy range. These readings and the forecast describe conditions around the announcement; they do not establish what air quality will be during every part of the Grand Prix weekend.
The Straits Times reported that, at 7pm on 7 October, each of Singapore's five regions had an unhealthy PSI reading: 106 in the north, 113 in the south, 130 in the east, 143 in the west and 136 in the central region. It said readings had been unhealthy across all five regions since noon that day. The paper also reported that NEA's forecast was the first since daily haze advisories began on 4 September to fall entirely within the unhealthy band of 101 to 200.
The two air-quality measures answer different practical questions. As The Straits Times explained, the 24-hour PSI is a rolling average of six pollutants used when planning outdoor activity for the following day. The one-hour PM2.5 reading gives a more immediate indication of fine-particle pollution. NEA advises people to consult the one-hour reading for immediate activities and the PSI forecast when planning ahead.
Health advice and the source of the haze
When the 24-hour PSI is unhealthy, NEA advises healthy people to reduce prolonged or strenuous outdoor exertion. It advises older people, pregnant women and children to minimise such activity, and people with chronic lung or heart disease to avoid it. The guidance varies with a person's health, the air-quality level, and the length and intensity of the activity.
NEA said moderate to dense smoke plumes from southern Sumatra had been observed drifting towards Singapore, alongside smoke haze from hotspots in Kalimantan. It expected dry conditions in those areas to continue and said prevailing winds could carry more smoke haze towards Singapore. That forecast helps explain why officials have prepared measures for the race weekend, but it is not a prediction that the event will be disrupted.
STB said tourism partners had been advised to follow daily haze outlooks and advisories through NEA's website or its myENV app and to take precautions in line with NEA advice. The unresolved question is whether air quality at the circuit will create a visibility, health or operational problem that calls for action. As of the statements reported on 8 October, no cancellation or actual restriction had been announced.
