Haze Policy - FAQs

Which Reading Do We Refer To?

Based on haze situation updates provided by Singapore National Environment Agency‘s (NEA), they provide 2 readings; the 24hr PSI Reading and the 1hr PM2.5 Reading. We will always refer to the 1hr PM2.5 Reading.

Why Is The 1hr PM2.5 Readings Used And Not The 24hr Or 3hr PSI Readings?

The 24hr PSI Readings are an average of the last 24 hours PSI readings. To achieve more accuracy, we use the latest 1 hour PM2.5 readings which are updated on an hourly basis by NEA.

Why Is The School Adopting A Cut-Off Level of 150 Using The 1hr PM2.5 Reading?

We obtain our on cautionary statements and information about the air quality and pollution measurement levels regarding PM2.5 from: www.aqicn.org

(0 – 50) Good: Air quality is considered satisfactory, and air pollution poses little or no risk.

(51 – 100) Moderate: Air quality is acceptable; however, for some pollutants there may be moderate health concern for a very small number of people who are unusually sensitive to air pollution. Active children and adults, and people with respiratory disease, such as asthma should limit prolonged outdoor exertion.

(101 – 150) Unhealthy For Sensitive Groups: Members of sensitive groups may experience health effects. The general public is not likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.

(151 – 20) Unhealthy: Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects. Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion

(201 – 300) Very Unhealthy: Health warnings of emergency conditions. The entire population is more likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.

(Above 300) Hazardous: Everyone may experience more serious health effects. Everyone should avoid all outdoor exertion

Are The Readings Location Specific?

Yes. NEA provides readings based on the five main parts of the island – North, South, East, West, and Central.

I Have A PSI/PM2.5 Reading Obtained From Another Website Which Is Different From NEA. Do You Recognised t This Reading?

No. We only base our updates according to Singapore’s National Environment Agency (NEA), and do not refer to readings listed on other sites. We believe that this is standard practice for all other government agencies to follow, such as Sport Singapore, and we abide strictly by these recommendations.

Can I Cancel My Child's Participation In Swim Class?

Yes. We understand that some children may be more susceptible than others, but if a parent decides to not allow the child to participate when the NEA 1-hr PM2.5 reading is between 100 – 129, a make-up arrangement will be made available, subject to availability. Please note no make-up classes will be made available should you miss the class when the NEA 1-hr PM 2.5 reading is below 100.
