 62. (1) This section applies to a fumigation if, (a) the fumigation is performed by means of a Class B pesticide that is a fumigant gas or chloropicrin; (b) the fumigation, including a fumigation of soil, is performed inside a building; and (c) the fumigant gas or chloropicrin is enclosed during the fumigation inside a sealed container or under a covering that suppresses the release of gas.  O. Reg. 63/09, s. 62 (1); O. Reg. 134/20, s. 28. (2) An exterminator who performs a fumigation mentioned in subsection (1) shall comply with the following rules: 1. The exterminator shall ensure that the building is not attached to another building and that the building is located at a sufficient distance from any other building, structure or area where humans may be exposed to the fumigant gas or chloropicrin, to prevent adverse effects. 2. Before the fumigation begins, the exterminator shall post Sign A, referred to in the Table to subsection 1 (5), on the covering or sealed container and all entrances to the building. 3. The exterminator shall monitor the air outside the covering or sealed container to ensure that at all times during the fumigation the concentration of the gas produced by the pesticide within the area covered by the distance mentioned in paragraph 1 is at or below the concentration specified in Column 2 or 3 of the Table to section 59. 4. The exterminator shall prepare a record of the concentration of the gas produced by the pesticide during the fumigation within the area covered by the distance mentioned in paragraph 1 and shall keep the record for a period of at least two years after the fumigation is complete. 5. The exterminator shall ensure that no person enters or remains in the building during the fumigation, except a licensed exterminator authorized to use the fumigant gas or chloropicrin or emergency personnel. 6. The exterminator shall ensure that a person mentioned in paragraph 5 who enters the building uses adequate respiratory protection and is accompanied by at least one other person mentioned in paragraph 5 who also uses adequate respiratory protection. 7. The exterminator and at least one other exterminator authorized to use the fumigant gas or chloropicrin shall be present during the introduction of the fumigant gas or chloropicrin and the airing out phase of the fumigation. 8. The exterminator shall ensure that all persons present during the introduction of the fumigant gas or chloropicrin and the airing out phase of the fumigation have adequate respiratory protection. 9. The exterminator shall lock the doors of the building where the fumigation is being performed by means of an external lock immediately after the introduction of the fumigant gas or chloropicrin, keep the doors locked until the airing out phase of the fumigation begins and keep the keys or other means of unlocking the door in his or her possession at all times during the fumigation. 10. The exterminator shall ensure that signs required by this Regulation to be posted remain posted at all times during the fumigation. 11. The exterminator shall perform tests in every room of the building in which the fumigation was performed to determine whether the fumigation is complete.  O. Reg. 63/09, s. 62 (2). (3) Despite paragraph 7 of subsection (2), only one licensed exterminator is required to be present during the introduction of the pesticide and the airing out phase of the fumigation if the fumigation is only performed by means of solid formulations of aluminum phosphide or magnesium phosphide.  O. Reg. 63/09, s. 62 (3).
