The World Health Organization (WHO) defines PM2.5 as fine suspended particulate matter with a diameter of less than 2.5 micrometres. PM2.5 can penetrate deep into the lungs and enter the bloodstream, causing adverse effects on the cardiovascular and respiratory systems.

The Ministry of Health (MoH) advised the public that when the PSI reading reaches the moderate range (51 to 100), outdoor activities may be carried out as usual.
Children, pregnant women, and the elderly are advised to reduce strenuous or prolonged outdoor physical activity, while individuals with heart or lung conditions are advised to limit such activities. Those experiencing persistent or worsening symptoms – such as coughing, shortness of breath, chest discomfort, or breathing difficulties – are advised to seek immediate medical attention at nearby clinics or health centers. Members of the public are also advised to refer to health advisories issued by the MoH from time to time for further guidance.
The public is also advised to call the Fire and Rescue Department at the emergency line 995 immediately for any incidences of bush and forest fires.
Meanwhile, the public should refrain from conducting any open burning activities and other actions that may worsen the haze conditions during the dry period.
