(Updated Sept 28, 2015)
The haze has struck again this year, even leading to the unprecedented closure of primary and secondary schools on Sept 25.
According to the National Environment Agency’s haze website, once the PSI reaches the unhealthy range (100 to 200), healthy people are encouraged to reduce prolonged or strenuous outdoor exercise, while the elderly, pregnant women and kids should do as little of such physical activities as possible.
If the haze seems to be worsening, the website also advises you to:
– Stay indoors and cut down on physical activity. Drink plenty of water.
– Close windows and doors so the haze particles can’t get in, but re-open them when the outdoor air quality improves.
– Use wet-cleaning methods like wiping or mopping, which don’t create much dust.
– Use fans and air-conditioners to cool air inside the house. But if the air-con doesn’t filter the air taken from outside, make sure to close the outdoor air intake opening.
– You can also try portable air purifiers, which help reduce the indoor particle levels. Click here for advice on portable air cleaners.
– If you have family members with chronic heart and lung conditions, see a doctor if they feel unwell.
