No owner, lessee, agent, factor, architect, or contractor engaged in and having supervision or charge of the building, erection, or construction of a block, building, or structure, shall neglect or refuse to place or have placed upon the joists of each story thereof, as soon as joists are in position, counter floors of such quality and strength as to render perfectly safe the going to and from thereon of all mechanics, laborers, and other persons engaged upon the work of construction or supervision, or in placing materials for such construction.

Whoever violates this section shall be fined not less than twenty-five nor more than two hundred dollars.

Each day that such person neglects or refuses to have such counter floors so placed, after notice is given by a building inspector, a chief inspector, or deputy inspector of the city building inspection department in cities where such department is organized, or by the superintendent of industrial compliance of the state, in cities where such departments are not organized, or from a person whose life or personal safety may be endangered by such neglect or refusal, is a separate offense.
