As temperatures rise across the UK, more people are being drawn to rivers, lakes, reservoirs and coastal waters to cool down. Unfortunately, periods of hot weather are often accompanied by an increase in water-related incidents and fatalities.
One of the greatest dangers is cold water shock. Even during a heatwave, open water can remain surprisingly cold. Sudden immersion can trigger an involuntary gasp response, rapid breathing, panic and loss of swimming control within seconds.
However, cold water shock is only one of many hazards associated with open water. Rivers, reservoirs and waterways can contain hidden dangers including strong currents, submerged structures, debris, sudden changes in depth, weirs, sluices and slippery access points. In many cases, these hazards are not visible from the surface.
This is where the principles of a Public Safety Risk Assessment (PSRA) become important. A PSRA is a structured process used to identify hazards, understand how people interact with an environment and implement measures that reduce risks while maintaining public access wherever possible.
Typical PSRA measures may include:
- Warning signage and public information.
- Clearly defined access and egress points.
- Safety equipment such as lifebuoys and throw lines.
- Edge protection, line marking and hazard delineation.
- Emergency planning and public awareness campaigns.
PSRAs are underpinned by the ERIC hierarchy of risk management:
Eliminate – Remove the hazard where reasonably practicable.
Reduce – Reduce the likelihood or consequence of the risk.
Inform – Provide clear information, warnings and guidance.
Control – Implement measures to manage any remaining risk.
Whilst flooding and severe weather often dominate resilience discussions, recent events highlight the importance of considering a wider range of climate-related risks, including heatwaves, open water safety and changing public behaviours during periods of extreme weather.
Reducing risks saves lives. By understanding hazards, informing the public and implementing proportionate control measures, we can help create safer and more resilient communities throughout the year.

Stay safe, stay informed and respect the risks associated with open water.
