F1 SMOG THREAT: The 2015 Singapore GP is threatened by haze due to forest fires, but officials say the race will go on. Image: Shutterstock
Singapore - Organisers of the 2015 Singapore GP said the haze situation caused by forest fires in Indonesia is volatile but there are no plans so far to cancel the event this weekend.
Rain gave the city a welcome respite from the acrid smog but the Pollutant Standards Index (PSI) which measures air quality remained at "unhealthy" levels and grey, fog-like smoke still shrouded the island.
Oganisers said there were no plans to amend the programme of the nightime street-circuit race and the glitzy public entertainment shows that come with it based on the current air quality levels, but acknowledged the situation was volatile.
Singapore GP said in a statement late Tuesday (September 15): "The haze situation is highly changeable not only from day to day, but from hour to hour.
"Therefore, it is currently not possible to reliably predict what the PSI level might be over the race weekend."
Indonesia on Tuesday deployed an extra 1600 military personnel to fight seasonal forest and farm fires on Sumatra island across the Strait of Malacca from Singapore.
Air pollution indices in Singapore were still in the moderately "unhealthy" range on Tuesday but businesses and schools were operating normally.
It reached "very unhealthy" levels after sundown on Monday, limiting visibility in the Marina Bay district where the race will be staged with parties and outdoor concerts on the sidelines.
In Malaysia, the education ministry ordered schools closed in Kuala Lumpur, three adjacent states and the administrative capital of Putrajaya.
Singapore GP said the air quality readings and relevant health advisory would be posted on its website and on its official mobile app to help fans "make informed decisions".
They will also be flashed on the giant screen in between races and broadcast on the in-circuit radio system. The health advisory will be posted on all entrances at the circuit.
It said protective respiratory masks "will be available for patrons throughout the ciruit park at cost price", while medical and first aid posts will be on standby "to handle any possible haze-related conditions".
Sivanandan Karunanandan (27), a Singaporean graphic designer, said the threat of a hazy race weekend would not keep him away from the annual festival.
He told AFP: "I am not really worried about the haze. I am just going to continue and go for the F1 events. I don't think it's going to get cancelled anyway."
International acts Bon Jovi, Maroon 5, Pharrell Williams, Spandau Ballet and Jimmy Cliff are the featured off-track performances this year.
A side event - in which Singapore's three fastest virtual Grand Prix drivers will race McLaren-Honda driver Jenson Button on a simulator - will now be held indoors on Wednesday instead of outdoors as earlier scheduled.
