Multistage incineration method for fire prevention and extinguishing in confined spaces

摘要

The inertization process involves decreasing oxygen concentration in the protective room from a base inertization level to a first lowered level in the event of a fire in the protective room. The oxygen concentration in the protective room is maintained at the first lowered level for a preset time interval. The oxygen concentration is decreased to a full inertization level if the fire has not been extinguished by the time the preset time internal has elapsed.
