Student Exposure to Outdoor Air Pollution

Monitoring Air Pollution Levels

The Health Services department will monitor daily air pollution levels as measured using the GIS
Air Pollution Monitor.

When there is elevated air pollution as evidenced by outdoor PM2.5 and PM10 particulate count, the
Health Services department will inform the staff and students in a timely manner. Decisions
determining which activities are limited or cancelled will be made in conjunction with the
PE/Sports department, the principals and the superintendent in accordance with the activity
restrictions aligned with the Air Quality Index (AQI) of the Environmental Production Agency of the USA
Government and the Thai Air Quality Index for Particulate Matter.

The nurse’s office will check the PM2.5 and PM10 levels at 9:00am and 1:00pm and will send all
staff email if readings fall into the unhealthy to sensitive groups or higher. The PE/Sports
department, the principals and the superintendent will be notified also by phone. Decisions
impacting afternoon activities as well as after school activities will be made by 1:30 p.m. Parents
and staff will be notified if pollution levels require a change in schedule.  Indepth

Reducing Student Exposure
Decisions for limiting activities, in order to reduce a student’s exposure to harmful air pollution,
will be based on individual student risk factors such as age and pre-existing medical conditions, as
well as the type of activity involved. Restrictions are aligned with the Air Quality Index (AQI) of the
Environmental Production Agency of the USA Government and the Thai Air Quality Index for Particulate
Matter.
