Rentokil Bubble in nitrogen anoxia treatment of museum pests |
| |
| Abstract: | AbstractThe Rentokil Bubble, a commercially available, portable, fumigation enclosure which was designed for use with methyl bromide (bromomethane), phosphine or carbon dioxide, was tested for its applicability for nitrogen fumigations. The unit would be a valuable alternative for museums where a costly fumigation chamber cannot be afforded or a permanent space cannot be allocated for fumigations. The performance of two bubbles, 35m3 and 6m3, was investigated for both the oxygen transmission characteristics of the materials and the gas-tightness of the enclosure. The tests confirmed the suitability of the bubble for anoxia treatment, although some practical limitations were detected, especially the size of the unit and possible variations in quality from unit to unit. The article describes the set-up and safety considerations of a large-scale nitrogen anoxia treatment using the bubble. |
