EMERGENCY PRESSURIZATION SYSTEM

(Breathing air system)

The EPS is an emergency system engineered to pressurize vital rooms/area inside onshore or offshore buildings that is necessary to protect from the accidental ingress of toxic gasses or harmful outdoor atmosphere. This requirement is fundamental during Fire&Gas Alarm Emergency Situation in order to protect personnel, equipment and emergency switchboard (typically in control rooms, emergency electrical rooms, safe haven, temporary refuge, muster area) until the restoration of a safe condition or the arrival of the rescue team. The requirement is met by using a piping/tubing network of breathable air, supplied inside the rooms in order to compensate the air leakage of the housing. The Compressed Breathing Air, necessary for the pressurization during the emergency time is stored inside high-pressure cylinders rack. The volume and the pressure of the cylinders is calculated in order to minimize the foot-print of the system and at the same time to assure the breathing and the pressurization (with a reasonable safety factor) for the duration of the emergency or until the stop of Gas Alarm (or other dangerous situations). The EPS can be used as a stand-alone system or in conjunction with HVAC system (temperature control of the area) and local chemical filters (typically CO2 scrubbers).
