OUR AIR POLLUTION POLICY

  • Bangkok Dolphins uses the official Thai government site for Air Quality and Noise Management together with the localised reading for each venue from the IQ Air Website.
  • Air Quality and Noise Management Bureau of Thailand. LINK TO PAGE
  • IQ Air Website. LINK TO PAGE
  • For each venue we refer to the closest monitoring station.
  • We refer to 2 sets of air pollution data: the general Air Quality Index (AQI) and also readings for PM 2.5.
  • The table on this page shows ranges of air pollution for both types of reading together with our responses.
  • We use the 24 hour average for both the PM 2.5 and AQI measurements as per the USA EPA guideline.

Our Process

  • Our Racquet Club office checks the information each morning from the IQ Air site. If there is an elevated reading the office will monitor the site hourly.
  • Of the two data sets (AQI and PM 2.5), we will act on the reading which indicates the greatest level of risk as defined on the table below.
  • For AQI over 150 we will continue to make checks throughout the day. If unhealthy levels are indicated and classes need to be cancelled, we will contact parents.
