Department of Air Protection
• Built in 1985 – 1992
• The highest construction in Prague (216m)
• Broadcasting technology (digital televisions, radios)
The Žižkov Tower
• Cell phone operator transmitters
• Army of the Czech Republic
• Joint rescue service
• Restaurant, Observatory cabin
• Owner České radiokomunikace a.s.
• Installed in 1989 by Total Walter company
• Protection of 16 fire areas, pressure vessels directly located in fire areas
• 2300 kg of refrigerant halon 1301 (CF3Br)
• ODP = 10
Contemporary fire protection system
• ODP = 10
• GWP = 80
• Extinguishing concentration: 3,5%
• Highest installation: 190-216 m
• Lowest installation: - 10 m
Contemporary fire protection system
• Project in 2011 - 2013
• LPG producer
• Extinguisher inert gas IG 541 (52% N2; 40% Ar; 8% CO2), mixture of natural gases from atmosphere
• 3562 kg
• ODP = 0
New fire protection system
• ODP = 0
• GWP = 0
• Extinguishing concentration: 35 – 47,5%
• Principle– oxygen reduction under 14,5% (fire goes out)
– above 10,5% (not evacuated persons can survive)
• Pressure vessels of 140l or 80l volume
• Stored in a gaseous state at a pressure of 300bar
• Extinguishing agent discharged from all nozzles installed at a
New fire protection system
from all nozzles installed at a time
• Protected areas must be adequately sealed
• Right concentration for 20 min ensures a perfect extinction
• Trigger mechanism operated electrically and pneumatically
• System is backed-up from and independent source for 24 hours
New fire protection system
• Placing on the position • Placing on the position of contemporary vessels + new installations in reconstructed areas
Extinguisher Comparison
IG 541 Halon 1301
52% N2; 40% Ar; 8% CO2 Composition CF3Br
0 ODP 10
0 GWP 80
• Fast extinguishment • No adverse effects
0 GWP 80
0 years Life in the atmosphere 80-150 years
• System installation + servicing
• Recovery of halon 1301 from old fire protection system
• Recycling, reclamation and vessels refilling (device REACHANLAGE by Kidde-
Servicing company ESTO Cheb s.r.o.
REACHANLAGE by Kidde-Deugra), 12€/1kg
• Halon 1301 stored in vessels in the Halon bank of the Czech Republic (ESTO Cheb, s.r.o.)
• Ozone Protection Programme by SEF in 2010 opened
• 4 areas of support– 1. Recovery and collection of ODS
– 2. Destruction of ODS
– 3. Implementation of alternative technology with zero ODP
Co-financing by State Environmental Fund (SEF)
– 3. Implementation of alternative technology with zero ODP
– 4. Measuring and monitoring of ozone layer
• Effectiveness analysis: ODP, GWP and TEWI
• Finance from fees payed by producers, importers of substances that deplete the ozone layer (cca 16€/1kg)
• In the Žižkov tower areas 1 and 3 supported
• Total cost of system installation and recovery: 576 360 €• SEF support of 30%: 172 902 €
Co-financing by State Environmental Fund (SEF)
