An arrangement for introducing a desired quantity of decontamination agent into a containment facility comprising:

• a) a tank as a storage vessel for storing the decontamination agent in liquid form;
• b) a metering apparatus having a spray nozzle that is directed into the containment facility so as to atomize the decontamination agent;
• c) a compressed air connection and a control unit so as to operate the metering apparatus, wherein
• d) the metering apparatus has a metering container that comprises a storage chamber that has a defined volume for receiving an individual portion of decontamination agent, characterized in that the storage chamber:
• a) is configured with a fixed or adjustable size;
• b) is provided as a separate container, a cylinder, a recess in the metering container or as an extended or drawn tube length;
• and
• c) the storage chamber has a volume in the range of 1 cm3 to 50 cm3,
• e) the storage chamber is provided so as to successively receive a number (n) of portions of decontamination agent from the tank and the portion that is respectively held in the storage chamber is provided so as to be introduced by means of the spray nozzle into the containment facility prior to receiving a subsequent portion, wherein the number (n) of portions for realizing the desired quantity of required decontamination agent may be selected between 1 and a whole number multiple of 1;
• and
• wherein in order to be able to adjust the size of the portion of decontamination agent that may be held in the storage chamber:
• a) a standpipe, a piston or an electrical probe, which may be inserted into the storage chamber and whose position may be adjusted;
• or
• b) a hose winding or tubing winding with a specific inner cross-section and length of winding are used.
