  2. Hypoxic air technology for fire prevention - Wikipedia

    en.wikipedia.org/wiki/Hypoxic_air_technology_for...

    Some oxygen reduction systems are integrated with traditional fire detection systems (e.g., smoke detectors or heat sensors) for an additional layer of protection. Ventilation Control Systems : In some installations, ventilation systems (or air-conditioning systems) may be used to adjust the airflow and maintain a stable atmosphere within the ...

  3. Purging (gas) - Wikipedia

    en.wikipedia.org/wiki/Purging_(gas)

    The system can be flushed with an inert gas to reduce the concentration of oxygen so that when the flammable gas is admitted, an ignitable mixture cannot form. In NFPA 56, [1] this is known as purge-into-service. In combustion engineering terms, the admission of inert gas dilutes the oxygen below the limiting oxygen concentration.

  4. Environmental control system - Wikipedia

    en.wikipedia.org/wiki/Environmental_control_system

    In aeronautics, an environmental control system (ECS) of an aircraft is an essential component which provides air supply, thermal control and cabin pressurization for the crew and passengers. Additional functions include the cooling of avionics , smoke detection , and fire suppression .

    The interactions between the components of the ISS Environmental Control and Life Support System (ECLSS) The International Space Station (ISS) Environmental Control and Life Support System (ECLSS) is a life support system that provides or controls atmospheric pressure, fire detection and suppression, oxygen levels, proper ventilation, waste management and water supply.

  7. Limiting oxygen concentration - Wikipedia

    en.wikipedia.org/wiki/Limiting_oxygen_concentration

    The limiting oxygen concentration is shown in the lower right of the diagram. The limiting oxygen concentration (LOC), [1] also known as the minimum oxygen concentration (MOC), [2] is defined as the limiting concentration of oxygen below which combustion is not possible, independent of the concentration of fuel. It is expressed in units of ...

    Diagram of a chemical oxygen generator system. There are currently three systems that are typically found on aircraft: A chemical oxygen generator system connected to all masks in the compartment. Pulling down on one oxygen mask removes the firing pin of the generator igniting a mixture of sodium chlorate and iron powder, opening the oxygen ...

    Diagram of a chemical oxygen generator system Chemical Oxygen Generator, Cut-away View. A chemical oxygen generator is a device that releases oxygen via a chemical reaction. The oxygen source is usually an inorganic superoxide, [22] chlorate, or perchlorate; ozonides are another promising group of oxygen
