British Airways

BA decided to install a High Pressure Water Mist fire suppression system to protect their ground floor Rotary UPS power generation machinery at their data centre in Heathrow. The project was deemed critical as the UPS machines work in conjunction with incoming mains power to ensure that BA can process the huge administration associated with running a major airline.

FIREWORKS designed, supplied and installed a local application style solution using our engineering skills to design and fabricate steel frames around each UPS machine to mount the piping and water mist nozzles on to give best placed protection.

The frames were designed to be removable without disconnecting any pipework to allow for annual machinery maintenance without the need for shutting the entire mist system down and without the requirement for repeated pipe integrity testing.

European Centre for Medium Range Weather Forecasts (ECMWF)

ECMWF were asked by their insurers to have a fire suppression system installed in a link building office complex and loading bay at their Reading Headquarters.

ECMWF

FIREWORKS won the contract with a design for High Pressure Water Mist that provided the best solution for all areas to be protected. FIREWORKS were appointed main contractor for this project and were directly responsible for all other trades working to integrate the new system with existing Fire alarm and BMS systems.

The system consisted of a basement mounted pump unit with integral water break tank connected to the fresh water mains feeding the two separate areas of protection.

The system is an automatic type that operates when one or more glass frangible bulbs, mounted in each discharge head, are broken by heat. Under stand-by conditions the piping is filled with 17bar of water but when running the system is charged to 100bar from the pump to the discharge heads.

Fujitsu

A new computer and communications complex was developed at Fujitsu’s Bracknell base. FIREWORKS designed, supplied and installed a High Pressure Water Mist system to protect all areas as part of the overall building project.

The system was designed as pre-action with distribution piping filled with compressed air at 6-7bar and water at 17bar held by a pre-action zone valve.

The High Pressure Water Mist was interfaced with a ‘double knock’ detection system and was designed to be double coincidence operation. This means that both a broken frangible bulb and a signal from the fire detection are required to discharge water into the protected area.

The mist system includes a main control panel, which monitors all circuits and equipment via a Pro Logic Computer (PLC). The system can be interrogated for running times, events and faults from a control panel mounted LCD controller.

Irish Ferries

FIREWORKS installed a 2000 nozzle High Pressure Water Mist system protecting all public and accommodation areas on board the Irish Ferries vessel “Normandy”.

The system comprised of a seven pump main unit located on deck two with twenty-one separate zones of protection throughout the ship.

As part of our programme of works Fireworks supplied a dedicated generator to power the pump unit mounted in a purpose built enclosure on deck 12.

In total approximately 4.5 kilometres of piping were installed during the 3 month installation period.
