FIRE SAFE INDOOR CLIMATE

HYPOXIC AIR

WHAT IS A FIRE SAFE

INDOOR CLIMATE?

An indoor climate may apply hypoxic air

technology (HA) for fire prevention, also known

as oxygen reduction system. HA is an active

fire protection technique based on a permanent

reduction of the oxygen concentration in

protected rooms: the oxygen concentration is

reduced typically from 21% (normal air) to 15%

(as inside passenger aircraft cabins).

In an hypoxic air environment, common materials

cannot ignite or burn while at the same time

people can work and breathe normally.

Air with reduced oxygen content is supplied to

the protected volumes: no gases other than

those present in normal air are supplied.

APPLICATIONS

• server rom, ICT, datacenter, industry, nuclear

power plants, mission critical rooms

• museums, galleries, libraries and archives:

hypoxic air reduces oxidation of artefacts or

documents to preserve them better

• fruit and vegetable storages: hypoxic air

reduces food deterioration

• large warehouses and freezer storages

where water based extignuishing systems are

less suitable

COWI SERVICES

• feasibility analysis, health and

safety assessment

• system specification and design

• integration in the building, engineering of

applications

• inspection for approval and certification of

system design, health and safety

HYPOXIC AIR

COWI - FIRST IN THE WORLD!

COWl is leading consultancy company on hypoxic air fire prevention since 2005.

COWl is internationally accredited as inspection body for hypoxic air fire prevention systems

to comply with BSI (British Standard Institution) and VdS standards.

COWl can inspect and approve design,operation,installation and integration of hypoxic fire

prevention systems in the building, The accreditation area include health and safety

assessment of the applications as well – a global first.

WHERE ARE HYPOXIC AIR FIRE

PREVENTION SYSTEMS INSTALLED?

Worldwide, more than 500 hypoxic air fire prevention systems are installed.

Most systems are installed in ICT rooms, archives, wharehouses,

data centres or freezer storages. COWI engages in diverse projects on

hypoxic air: a 250 000 m³ archive in UAE, a 200 000 m³ freezer storage in

New Zealand and a nuclear power plant in Sweden.

Also, a 35 000 m³ data centre inside a mountain plus multiple smaller

projects.

Fire safe indoor climate: you can work and occupy the room as normal;

the air is very clean
