Berlin police deployed riot water cannons to spray water and cool crowds during an extreme heatwave on June 28, 2024 [3].

The repurposing of tactical equipment for public health highlights the severity of the temperature spike in Germany's capital. As urban areas struggle with the "heat island" effect, emergency services are finding unconventional ways to prevent heat-related illness among pedestrians.

Authorities in Berlin utilized the high-capacity sprayers to provide immediate relief to people gathered in the city streets [1], [2]. The move transformed tools typically used for dispersing protests into a mechanism for public cooling. By spraying water into the air and onto the crowds, the police aimed to lower the ambient temperature for those trapped in the heat [1], [2].

This incident occurred against a backdrop of dangerous swimming conditions across the country. As residents sought relief in natural bodies of water, fatalities rose. Reports on the death toll vary, with some sources saying at least seven people died in swimming accidents [1], while other reports indicate the number reached 13 [2].

The use of water cannons was a targeted response to the extreme weather conditions affecting the region [1]. While the police are trained to use these vehicles for security and crowd management, the shift to a humanitarian application reflects the urgency of the weather crisis. The deployment focused on high-traffic areas where residents were most vulnerable to the heat [2].

Public health officials have continued to warn citizens about the risks of extreme heat and the dangers of swimming in unmonitored waters during such spikes. The disparity in reported deaths underscores the volatility of the situation during the 2024 heatwave [1], [2].

The use of riot control equipment for heat mitigation suggests that traditional urban infrastructure in Berlin is insufficient for extreme temperature spikes. The contradiction in swimming fatality numbers—ranging from seven to 13—further indicates a fragmented emergency response or reporting system during climate-driven crises.
