Move classes online when API hits 100, say health experts

Health experts recommend closing schools and moving classes online when the air pollutant index (API) reaches 100, instead of requiring children to wear surgical masks. Dr Sharifa Ezat Wan Puteh of Universiti Kebangsaan Malaysia argues that children are more vulnerable due to underdeveloped lungs and should only return to school once the air quality improves.

The hazy conditions in Malaysia, caused by forest and land fires in Kalimantan, have resulted in unhealthy API readings in several regions. While the education ministry requires schools to halt outdoor activities when the API exceeds 100, they only close when it surpasses 200. Pediatrician G Naveen Nair suggests that moving children indoors is a crucial first step during periods of poor air quality, but also emphasizes the need to address classroom air quality.

Proper ventilation is still necessary, but classrooms should not be fully sealed. Air filtration systems can help, but surgical masks are ineffective against the fine particles in haze, and N95 respirators may not fit well or provide sufficient protection for children. The health ministry advises that ordinary surgical masks do not filter out the fine particles in haze, while N95 respirators offer better protection but may cause discomfort and a false sense of security in children.
