Belgium activates alarm phase of the Ozone and Heat Plan
The Belgian Risk Management Group (RMG) officially activated the alarm phase of the Ozone and Heat Plan on June 23, 2026. This decision was made due to the persistent high temperatures and rising ozone concentrations in the air. The plan is intended to protect the population, and vulnerable groups in particular, against the health risks of extreme heat.
The Ozone and Heat Plan comes into effect when meteorological conditions may pose a threat to public health. High ozone levels can lead to respiratory problems, eye irritation, and fatigue. The elderly, young children, and people with chronic conditions are at an increased risk during these periods.
Authorities advise citizens to avoid physical exertion during the hottest hours of the day and to drink plenty of water. In addition, it is important to seek cool places indoors and to ventilate rooms well when the outside temperature is lower. It is also recommended to stay in regular contact with vulnerable people in the area.
The government continues to closely monitor the situation via measuring stations spread across the country. If weather conditions change or ozone concentrations decrease, the alarm phase will be adjusted or terminated. Citizens are urged to keep an eye on the official channels of the FPS Public Health for further updates and advice.
