Case Study HMP Glen Parva/Fosse Way – Award-Winning Fire Protection

Water mist design & Installation for one of the UK’s largest, most modern prisons

Fireworks was entrusted to design and install a complete water mist fire protection system for HMP Fosse Way, one of the UK’s largest and most modern prisons. Fireworks used Hydramist water mist fire protection solutions specifically designed for the custodial sector and worked in close collaboration with other contractors on this major project. Fireworks received a special Supply Chain Award from Laing O’Rourke, for its outstanding contribution to project certainty over the 18 months of the project.

Fire protection for HMP Fosse Way, a prison designed to provide a secure, safe environment.

HMP Fosse Way is a £286m facility, on the site of the former Glen Parva prison. Built to accommodate nearly 2,000 prisoners, Fosse Way is designed to provide a secure, safe environment for inmates and to aid reintegration through its state of the art educational, training and sports facilities.

The construction is one of the large titan-style prisons within the UK government’s plan to create 20,000 new prison places. At HMP Fosse Way, there are seven, four-storey house blocks. Each self-contained house block comprises four wings of cells, with a central hub for catering, laundries, workshop, and association spaces.

Fireworks’ award-winning project management for HMP Fosse Way

Fireworks custom designed the water mist fire protection system to protect Fosse Ways’ cells, association spaces and other risk areas. Fireworks’ in house design team worked with advanced 3D software to optimise the integration and space used by the fire protection system. Much of the pipework, risers and valves were pre-assembled and easily slotted into place on site.

On site, Fireworks’ project managers and engineers completed the project respecting all requirements and timelines, while working closely with other contractors to achieve the highest satisfaction for all aspects of the project. Fireworks’ Supply Chain Award from Laing O’Rourke was in recognition of its outstanding contribution to the overall project certainty of HMP Fosse Way.

Automatic In-cell fire protection systems to enhance life safety

The Fireworks fire protection system for cells at HMP Fosse Way are powered by Hydramist 300 MPS water mist pumps located in the plant room of each houseblock. In addition, Hydramist 200 MPS pumps are used for the segregation units. All pumps have integrated water storage break tanks and are compliant with Ministry of Justice STD/M/SPEC 054-specifications.

The pumps are connected, via stainless steel pipework, to the wall mounted Hydramist anti-ligature water mist nozzles located in each cell. In the event of a cell fire, water mist is emitted at high pressure to the affected area only. Fire and heat are suppressed in minutes and smoke spread is rapidly reduced to maintain a breathable environment for detainees and prison staff.

Hydramist water mist hose reel cabinets to reach all areas of house blocks

In addition to the in-cell water mist nozzles, Hydramist water mist hose reel cabinets were installed in the central communal hubs of all seven house blocks, on each of the four floors.

Designed specifically for the custodial sector, the STD/M/SPEC 045-compliant hose reel units are robust and tamper-proof. Each unit comprises a hose reel assembly with 50 metres of high pressure, impact-resistant hose and a manually operated lance with a high-pressure water mist nozzle. Long enough to reach all areas of the house blocks, the hose reel can also be used to project water mist through inundation points located in cell doors.
