The City Center for Disease Control assessed that 27/95 schools monitored for lighting met the standard, accounting for 28%; 17/95 schools monitored for noise met the standard (accounting for 18%), schools located near traffic routes or with gyms near classrooms had noise levels higher than the standard allowed.

27/95 monitored schools had CO2 concentrations that met the requirements, accounting for 28%. Most schools that used air conditioners but did not have exhaust fans had CO2 concentrations higher than the permitted standard.

In particular, according to survey results, up to 46/95 schools did not meet the requirements for light, noise and CO2 concentration in classrooms, at a rate of 48.42%.

Only 7/95 schools met the requirements for monitoring light, noise and CO2 concentration, a rate of 7.36%. Most schools only met 1-2 criteria.

Through the results of monitoring schools in the city, the City Center for Disease Control recommends that the Department of Education and Training, district and commune health centers and Thu Duc City coordinate to monitor classroom hygiene indicators such as light, noise, and CO2 concentration of schools in the area every year.

Schools need to increase lighting in classrooms that do not meet lighting requirements, increase air exchange in classrooms that do not meet CO2 concentration requirements, review and arrange enough hand washing taps according to regulations, soap and hand washing procedure charts.
