Under what circumstances do we need to wear mask and what are the advisories on the use of mask?
When the 24-h PSI level exceeds 150 in the 'Unhealthy' range, people with existing heart or respiratory ailments or those who are more susceptible to smoke haze are advised to wear a respiratory mask when they go outdoor. People with respiratory ailments are however, advised to consult their doctors on the use of respirator masks.
Respiratory masks, such as N95 masks, are designed to keep out fine particulate matter and hence, protect the wearers from breathing in the smoke haze particles in the air. The mask should be changed when it gets soiled or distorted in shape. Surgical masks and paper masks do not provide adequate protection from the haze particles. 20 seconds ago - View -

SINGAPORE - As of 1pm today, the three-hour Pollutant Standards Index (PSI) stood at 371.
This is a steep jump from noon, when the haze was just two points away from re-entering "hazardous" levels.
At noon, the three-hour PSI reading stood at 299, before rising to 371 at 1pm. A PSI of above 300 means air quality is "hazardous" to health.
This is a steep climb from the 11am PSI reading of 198. The PSI started with 137 at 7am this morning. 2 minutes ago - View -
