F1 Singapore Grand Prix 2015: Weekend under threat from giant smog cloud as organisers admit conditions are changing by the hour

The Singapore Grand Prix could be under threat from smog created by Indonesian farmers burning forests to clear land for agriculture, with the Marina Bay Street Circuit currently engulfed by a thick cloud.

The city-state regularly comes under a haze blown over from near-by Indonesia at this time of year, although it has triggered fears over visibility as the F1 circus rolls into turn this weekend.

Race organisers insist that there is no plan to alter or cancel the Grand Prix, but that is due to conditions changing hour by hour rather than having a good idea what will happen over the weekend.

Current Pollution Standards Index levels are registering between 126 and 151

A statement released by the organisers said: “Based on the current PSI levels, there are no plans to amend the published racing and entertainment programme.

“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. We will continue to work closely with all the relevant government authorities to receive the best possible forecasts when they are available.

“Singapore GP has put in place a number of measures for the race weekend:

“In order for our patrons to make informed decisions on the haze situation, the PSI reading and relevant health advisory will be displayed on the Singapore GP website (www.singaporegp.sg), official Singapore GP mobile app, the giant screens between races and broadcast on the in-circuit radio system. The government health advisory will also be posted at all Circuit Park entrances.

“N95 masks will be available for patrons throughout the Circuit Park at cost price.

“All of our 24 medical and first aid posts have been placed on standby to handle any possible haze-related conditions.”
