NEA to provide daily haze advisories from Sep. 4, after 24-hour PSI crossed 100 in Central S'pore

Singapore’s 24-hour Pollutant Standards Index (PSI) entered the "Unhealthy" range in the morning of Sep. 4, as hazy conditions affected the country.

The PSI first crossed 100 at 7am, and reached 105 at 10am, according to the National Environment Agency's (NEA) website.

Air quality is classified as "Unhealthy" when the 24-hour PSI exceeds 100.

The Meteorological Service Singapore said earlier this week that hazy conditions are expected in the first half of September, with dry weather causing an increase in hotspot activity and smoke haze in the region.

In a joint media release issued on behalf of agencies in the Haze Task Force (HTF) on Friday, NEA said it will begin issuing daily haze advisories from Friday evening.

This is the first time the PSI has entered the "Unhealthy" range due to haze since Oct. 8, 2023, the agency said.

Daily haze advisories

Agencies under the HTF have implemented their respective action plans and advisories to protect the health and well-being of the public, NEA said.

The agency’s daily haze advisories will include a 24-hour PSI forecast, which members of the public can use to plan activities and events for the following day.

It added that the health impact of the haze is dependent on each individual’s health status, the PSI level, and the duration and intensity of outdoor activities.

Reducing outdoor activities and physical exertion can help minimise the effects of haze exposure, NEA said.

The public is also advised to drink plenty of water to stay hydrated.

People with chronic heart and lung conditions should also ensure that their medication is on hand and readily accessible.

Vulnerable persons, especially the elderly, pregnant women, children, and those with chronic heart and lung conditions should seek medical attention promptly if they develop symptoms or feel unwell, said the agency.

Current air quality readings and advisories are available on www.haze.gov.sg, www.nea.gov.sg, as well as the myENV app.

The Ministry of Health (MOH) has also worked with healthcare institutions and long-term care providers to put haze preparedness measures in place.

These include the use of air purifiers and fans, as well as portable air coolers, where appropriate, to reduce ambient temperatures.

The public healthcare institutions are also monitoring patients closely for possible health effects of the haze and will provide appropriate medical intervention where necessary, NEA affirmed.
