Fumigating objects and devices which have been attacked by pests

摘要

Fumigating objects and devices which have been attacked by pests uses a treatment room and CO2 and a toxic gas. The CO2 and the toxic gas (namely sulphuryl fluoride, carbonyl sulphide MeI or CO) are introduced into the treatment chamber (1) at the beginning of the process in such a manner that an initial predetermined value (B) of the concn. of the toxic gas is first achieved when the CO2 concn. in the treatment chamber (1) is increased. During most of the treatment time (T2) and the initial period of gas introduction (T1), the CO2 concn. in the treatment chamber (1) is higher than the concn. of toxic gas. Also claimed is the equipment for carrying out the above process.
