Abstract: Provided are methods for decontamination of compartments, such as aircraft compartments and other types of compartments, and systems for implementing these methods. In some embodiments, a method involves detecting presence of one or more contaminants in a compartment. This information is used to select various decontamination conditions. In some embodiments, additional information, such as the type of the compartment (e.g., an aircraft compartment), temperature, and humidity, may be also considered while selecting the decontamination conditions. The decontamination conditions include identification of one or more decontaminating agents to be dispensed in the compartment, temperature profile of the air to be flown into the compartment, and timing of the decontaminant dispensing and air flowing operations. These conditions are selected to increase efficacy of the selected decontaminating agents with respect to the one or more detected contaminants and reduce impact on the aircraft compartment.
