Immediately after their appointment, the directors shall meet and organize by electing one of their number as president and one as secretary and by electing such other officers as they may deem necessary. They shall adopt such by-laws, rules, and regulations for their own guidance and for the government of the public health board as may be expedient and not inconsistent with this Division 17 or with the ordinances of the municipality. They have the exclusive control of the expenditure of all money collected to the credit of the public health board fund. All money received for the public health board shall be deposited in the municipal treasury to the credit of the public health board fund and shall not be used for any other purpose. The money shall be drawn upon by the proper municipal officer upon the properly authenticated vouchers of the board of directors.
The board has the power to appoint suitable assistants and other employees and fix their compensation, and to remove such appointees. The board, in general, shall carry out the spirit and intent of this Division 17 in establishing and maintaining a public health board. In a city which has adopted or hereafter adopts Division 1 of Article 10, all appointments and all removals of assistants or other employees shall be made pursuant to the provisions of that Division 1 of Article 10 and not otherwise, except that persons may be employed temporarily until persons ranked upon the register under Division 1 of Article 10 for positions or offices which are held under Division 1 of Article 10 are available for service. Persons so appointed for temporary service shall hold their positions as temporary appointees under Division 1 of Article 10.
Each officer and employee of the public health board is an officer or employee, as the case may be, of the municipality in which the public health board is established.
