HI-FOG® Water Mist Fire Protection System Safeguarding your building, detainees, your staff and the environment Minimising fire & smoke damages Keeping your prison running
Special Risks & Problems An efficient, sustainable and safe solution is needed The safety of the detainee is the responsibility of the authorities (you cannot leave the detainee in an untenable environment) The safety of the staff is the responsibility of the authorities (you cannot send guards into an untenable environment or ask them to open the cell without adequate precautions) The system should be vandal proof and provide no ligature points Prisons are typically overcrowded and need cells available The safety of the detainee is the responsibility of the authorities (you cannot leave the detainee in an untenable environment) The safety of the staff is the responsibility of the authorities (you cannot send guards into an untenable environment or ask them to open the cell without adequate precautions) The system should be vandal proof and provide no ligature points Prisons are typically overcrowded and need cells available
Fires in prisons are difficult Most fires are deliberately caused by detainees Detainees cannot escape from the fire The prison cell in a small confined space Most fires are set in a position which is difficult to attack (i.e. shielded fires, for example on the bottom bunk beds) Often, the detainees are agitated or violent Fires and prisoner injuries or deaths are widely reported
The Conundrum… You cannot just leave your detainees in their cell during a fire. You cannot just open the doors, you must follow procedures. You cannot send a guard into an untenable cell. The only course of action is to make the cell tenable during a fire, so that the detainee can remain in the cell until staff are prepared to rescue the detainees.
What is a Tenable Environment? Typical figures set for prison tenability are: Maximum carbon monoxide (CO) concentration of 1,500 ppm Maximum carbon dioxide (CO2) concentration of 5% Oxygen (O2) concentration to stay above 14 % Maximum temperature 80°C These concentrations are limiting values that are immediately dangerous-to life or health and represent currently accepted values for these gases for exposures of a number of minutes, usually 30 minutes*. *The typical time for guards to be ready to effect the rescue is 15 minutes.
HI-FOG performance against the tenability criteria In recent third party prison tests the following were measured: Maximum carbon monoxide (CO) concentration of 1,500 ppm PASS
HI-FOG performance against the tenability criteria In recent third party prison tests the following were measured: Maximum carbon dioxide (CO2) concentration of 5% PASS

Smaller is Better! Smaller tubes compared to traditional sprinklers, means smaller holes need to be drilled in walls. Smaller tubes compared to traditional sprinklers, means less weight of the system. Smaller water usage (typical 10 – 30% of traditional sprinklers) means smaller water storage tanks. Smaller water usage (typical 10 – 30% of traditional sprinklers) means less water damage in the cell.
Flexibility in Design Prison systems can be driven by: Electric Pumps (SPU) Diesel Pumps (SPUD) Gas Driven Pump Units (GPU)
Flexibility in Design Discharge can be activated: Manually at the section valve Automatically by fire detection system Automatically timed by fire detection system Discharge can be activated: In a single cell In groups of cells System can be supplemented with hydrant system for manual extinguishment of the fire NS12 Section Valve Hydrant
What is HI-FOG® Water Mist? Oxygen Combustibles Heat Unbreakable chain reaction Principle of operation HI-FOG® Provides efficient cooling as well as radiant heat blocking HI-FOG® Water mist evaporates efficiently thus providing local inerting at the heart of the fire

HI-FOG® Water Mist in Real Life
To Summarise With HI-FOG you can get gaseous penetration and space filling in 3D with the fire fighting agent. Without the downsides of gas based or conventional sprinkler systems
What Does HI-FOG Offer? Less Construction Work Minimized Fire and Water Damage to the Prison and Equipment Fast & Easy Installation Better Personnel Safety Minimum Cell Downtime Saved Money High Safety Minimum Disturbance to Business
Where can HI-FOG® prison systems be used From small holding cells to large prisons: Cells within police stations Cells within court facilities Detention centres Application processing centres Prisons Note! HI-FOG® water mist is not applicable only for the cells but all the other ancillary spaces can be protected as well. Electrical rooms, visiting areas, corridors, offices, communal areas, restaurants, kitchens, storage rooms, backup generator areas etc.
