Container fumigation

As container fumigation is called the procedure with the z. B. Packaging materials and transport aids made from fresh, unprocessed wood are protected from pests and mold during transport in containers .

For this purpose, containers are treated with gaseous insecticide and mold poison after loading . The problem is z. B. fumigation with bromomethane (methyl bromide), which can damage the ozone layer. An ecologically more responsible alternative process is z. B. the thermal treatment (see also heat disinfestation ) of the container in heating chambers or fumigation with carbonyl sulfide (COS) or sulfuryl fluoride (SO ₂ F ₂ ). The very high global warming potential (4,870 CO ₂ equivalents) of sulfuryl fluoride must be taken into account .

The most common chemicals found in containers are:

• Monophosphine
• benzene
• formaldehyde
• 1,2-dichloroethane
• Trichloronitromethane
• Methyl bromide
• 1,4-dioxane
• Ethylene dioxide
• Sulfuryl difluoride
• Hydrogen cyanide
