On 20 June 2013, the PSI reaches a new high of 371 and the PM2.5 index reaches a very unsafe level of 246 (Normal index should be below 40). If necessary, PM Lee will pass an order to stop work and activities when the index goes higher.
Extracted from PM Lee Hsien Loong Facebook Page:
Just back from my Meet-the-People Session. We were all tracking the PSI during the MPS, and dismayed that for a time it went above 300. Minister Vivian has briefed the press to explain what we are doing, and guide the public on how to respond (http://bit.ly/10xFN8c).
Cabinet had discussed the haze situation fully when it met this afternoon. But as the haze has worsened, I am meeting the relevant ministers again first thing tomorrow, and will brief the press after that.
Meanwhile, if the PSI reading stays high, please stay indoors where possible and avoid heavy outdoor activities. Look out for one another - we will get through this together. - LHL
