Netherlands heatwave triggers safety measures in schools, waste services and health sector

The Royal Netherlands Meteorological Institute (KNMI) has issued an orange alert as daytime temperatures are expected to reach 35‑39 °C and nighttime lows remain above 20 °C. To protect the public and workers, municipalities and service providers have introduced a range of emergency protocols.

Schools across the country are operating on a shortened "tropenrooster" with lessons limited to 45 minutes and early dismissals, while some institutions provide alternative childcare options for parents. Waste‑collection companies such as Circulus have moved collection times to early morning (06:30‑14:00) and closed recycling sites earlier to avoid exposure of staff to peak heat. Municipalities like Het Hogeland are deploying salt‑spreading trucks to keep asphalt from softening under surface temperatures that can exceed 60 °C.

Health professionals at the Spaarne Gasthuis warn that the extreme heat puts elderly people, young children and those with chronic conditions at high risk of dehydration, heat‑stroke and related complications. They advise frequent water intake, avoiding strenuous activity between 12:00‑18:00, seeking shade, and checking on vulnerable neighbours. The National Crisis Centre and the Risk Management Group have issued public guidance on hydration, sun protection and emergency response.

Together, these coordinated actions aim to reduce heat‑related health incidents, maintain essential services and safeguard infrastructure during the unprecedented Dutch heatwave.
