The haze and smoke intensifies in Singapore on Day Five of the condition. Forest fires from Sumatra, Indonesia have caused heavy amounts of smog in neighboring Singapore, and PSI (Pollution Standards Index) levels are at a record-crushing 400. This is categorized as both "unhealthy" and "hazardous." Local government has advised people to stay indoors, though smog has seeped into many buildings.
