Boston Medical and Surgical Journal
one of the most prominent exhibits in the exhibition hall, attracting far more attention than any other state exhibit on the subject, and receiving many favorable comments from persons seeking subjects and exhibits of an entirely different nature. Accompanying this occupational exhibit was an attractive illustrated pamphlet describing the photographs, photomicrographs, charts and occupational dust specimens exhibited. The general purpose of the exhibit was educational. The photographs and
... otographs and materials presented had three distinct aims: (1) to show conditions surrounding persons who work in the most sanitary establishments in some of the leading industries in Massachusetts; (2) to make clear the possibility of preventing diseases and pathological changes which now accompany certain occupations and manufacturing conditions; (3) to demonstrate that factory hygiene is a part of community hygiene. The exhibit illustrated conditions wdthin the factory that are of special interest to the sanitarian in connection with model sanitary home conditions in factory communities. The exhibit also contained photographs of model factory communities, showing old and modern homes of a comfortable and satisfactory type for persons who work in manufacturing establishments. Dust in its infinite variety as it occurs in modern industrial life, and the great havoc it plays in the industrial workers was one of the striking features of the exhibit. Forty different occupational dusts collected by the Massachusetts health authorities in the course of an intensive study of occupational hygiene were exhibited, together with the same number of photomicrographs showing the particles of dust enlarged 164 times. In these photomicrographs was clearly to be seen the different characteristics of the irritating and poisonous dusts that occur in the manufacturing processes of the textile, boot and shoe, and other Bay State industries. Accompanying the photomicrographs were photographs of the peculiar processes giving rise to the dust, which in its turn had given rise to the numerous diseases of the lung and air passages so prevalent among the present day factory workers. As a kind of text for the photomicrographs, the first wing of a large display fixture bore an enlarged photograph of healthy lung tissue, following which were enlarged photographs of sections of the lungs of metal workers who had been exposed for years to fine steel and iron dusts, bringing on a pathological condition of the lung tissue known as fibrosis. Specimens of dust exhibited were classified in two main groups, the irritating and the poisonous. The first group, which included dusts of vegetable, animal, metallic and mineral origin, was the more common. Dust in the poisonous group was of metallic and mineral origin. Among the actual dust specimens shown were cotton, broom corn, rattan, granite, steel, iron, emery, and the many kinds of dust that were encountered in the boot and shoe industry. Samples of brass, zinc and lead were representatives of the poisonous group. Interesting in this connection was the photograph of a man at work in the manufacture of storage batteries.
