The 3-hour PSI reading rose slightly to 49 at 10am. The previous reading at 9am was 47.
The air quality has improved on Sunday. The 24-hour PSI at 4pm on 23 June 2013 is 82-95. The improvement in the air quality is due to a change in the direction of the low level winds over Singapore, from southwesterly to southerly, since last night.
The prevailing wind conditions are expected to persist for the next few days.
The 24-hour PSI for the next 24 hours (23 June, 6pm – 24 June, 6pm) is expected to be in the Moderate band (51-100).
Avoid prolonged/strenuous outdoor physical exertion
Elderly, pregnant women and children
Minimise prolonged outdoor activity
People with chronic medical conditions especially lung or heart disease
Avoid all outdoor activity
Wear N95 mask if prolonged outdoor activity is unavoidable.
The use of N95 mask increases the effort in breathing and may cause discomfort, tiredness or headache. As some people with chronic lung disease, heart disease or stroke may already have reduced lung volumes or breathing issues, they should stop using a N95 mask if they feel uncomfortable. They should consult their doctor as to whether they can use the N95 mask.
Those who are not feeling well are advised to seek medical attention.
Employers are advised to provide suitable respirators to all employees carrying out outdoor work. They should also deploy susceptible employees to work indoors, preferably doing work which is not physically strenuous.
