Belgium activates alarm phase of the Ozone and Heat Plan
The Risk Management Group (RMG) activated the alarm phase of the national 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 aims to protect the population against the health risks associated with these extreme weather conditions.
The Ozone and Heat Plan is intended to provide extra support to vulnerable groups, such as the elderly, young children, and people with health problems. During the alarm phase, various measures are taken to limit the impact of the heat. For instance, healthcare institutions are put on high alert, and advice is being disseminated to prevent health problems caused by overheating.
Authorities advise citizens to avoid physical exertion during the hottest hours of the day and to drink plenty of water. It is also important to keep homes cool by keeping windows and doors closed during the day and using sun protection. It is further recommended to stay in regular contact with vulnerable people in the vicinity.
Air quality may temporarily deteriorate due to high ozone concentrations, which can primarily cause respiratory problems. People with asthma or other lung diseases are asked to be cautious during outdoor activities. The government continues to monitor the situation closely and will share new information as soon as weather conditions change.
