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

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)
