valves etc., are fully sealed with tape to prevent loss of fumigant to the laboratory.
NOTE 2: WARNING! Fumigation gasses are toxic and as such must be handled with the correct
precautions. Persons carrying out the fumigation process must be adequately trained and are advised to
wear appropriate personal protection equipment. During the fumigation cycle, a warning notice stating
“ CABINET BEING FUMIGATED – DO NOT USE” should be displayed on the front of the cabinet.
