§ 154-5. Preparation for fumigation; inspection prior to reentry.

A. 

There shall be two or more men on every fumigation, one of whom must be a competent and experienced fumigator. These men must be present at the time of releasing the fumigant and during initial ventilation. During the interim, the premises shall be adequately safeguarded against entry by any human being.

B. 

Any building or other enclosed space to be fumigated shall be sealed in such manner as to confine the fumigant to the space intended to be fumigated.

C. 

Warning signs shall be posted at all entrances. These signs shall be not less in size than 10 inches to 12 inches, printed in red or contrasting colors, displaying skull and crossbones, the words "danger" and "poison gas" in two-inch block type, the type of fumigant and the name, address and telephone number of the holder of the fumigator permit.

D. 

All members of the fumigating crew must be equipped with serviceable masks of a type approved by the United States Bureau of Mines, with the correct canister for the type of gas used, and shall wear such mask while in the enclosed space during and after liberation of the gas, until ventilation is completed.

E. 

Prior to releasing the fumigant, all accessible doors and windows and other means of ingress shall be locked, secured or barricaded, and such safety appliances as may be necessary shall be employed. When fumigating dwellings or buildings, it is required to use safety locks to cover existing locks and keyholes so that the original door locks and keys cannot be used to gain entrance.

F. 

No person shall be permitted to reenter the fumigated premises until the fumigator shall have ascertained by personal inspection without a gas mask that the building is safe for occupancy.
