How high pressure water mist works in custodial facilities

Compact, powerful high-pressure pumps feed patented water mist nozzles, via a network of stainless-steel pipes. In the event of fire, the nozzles are triggered at the affected areas to emit ultra-fine water mist under high pressure.

The water droplets in the watermist are less than 100 microns each. Under heat, they quickly atomise to cool and suppress fire and smoke. Once the fire has been extinguished, the water mist continues to reduce the heat temperature, preventing re-ignition.


Automatically operated water mist systems

In automatically operated systems, in-cell nozzles are heat-activated directly at the point of fire, triggering the water pump. The nozzles emit ultra-fine water mist under high pressure. Each water particle is a thousand times smaller than a regular droplet. Under heat, the water particles atomise to rapidly combat fire, smoke and heat. The unparalleled cooling properties of high pressure water mist also prevent re-ignition of fires. As only very small amounts of water are used, there is minimal disruption to prison operations.


Manually-operated water mist systems

Active, manually operated high pressure systems work on the same principle, using wall-mounted hose reel cabinets or mobile units fitted with high pressure water mist nozzles. These manually operated water mist systems are often used in parallel with automatically operated systems for larger prisons, or as a standalone solution for smaller custodial suites.


Testing and approvals

All the water mist systems we use are approved and tested by the Ministry of Justice, His Majesty’s Prison Service, the Building Research Establishment (BRE) and the Commonwealth Scientific & Industrial Research Organisations. Throughout the custodial sector, water mist solutions have been proven under controlled tests and in real life situations.

Fireworks is the leading fire suppression company for the Custodial Sector in the UK. Entrusted by the Ministry of Justice for nearly two decades, Fireworks protects over 250 prisons, custodial suites and immigration centres in the UK and overseas.
