Protection for the clothing, however, where splashing is incidental to the operations, cannot be dispensed with. Hence either the overalls themselves or the front of them should be made of some light ventilated waterproof material, or a waterproof apron worn over overalls of the kind at present in use. Daily sponging would then take the place of washing. If lead dust be visible on the hair of workers, there must be a defect in the conditions of work to be rectified by other means than cumbering the head. In our opinion, head coverings ought never to be necessary. We cannot think that an attack of plumbism can ever be precipitated by the amount of lead dust inhaled on brushing the hair. A common provision in regulations for overalls is: “Overalls shall be provided for all persons employed in lead processes, and shall be washed or renewed every week. “The occupier shall provide and maintain for the use of all persons employed in lead processes--(_a_) A cloakroom or other suitable place in which such persons can deposit clothing put off during working hours, and separate and suitable arrangements for the storage of overalls required by regulation; (_b_) a dining-room, unless all workers leave the factory during meal-hours. “All persons employed in lead processes shall wear the overalls provided ... and shall deposit such overalls and any clothing put off during working hours in the places provided under the regulations. The overalls shall not be removed by persons employed from the factory or workshop.” General sense of propriety--and it is on this ground, and not from danger attaching to non-observance, that we press it--suggests that overalls should be kept apart from working clothes, and preferably outside any room in which a lead process is carried on. So long as actual contact between the two sets of garments is prohibited, we do not see objection to the same cloakroom sufficing for both. The best arrangement that we have seen is a room in which each worker has two lockers--one for the storage of overalls, and the other for clothing put off during working hours. This presupposes supervision and effective discipline. We think that all reasonable need in the provision to be made is met by numbered pegs on one side of the room or wide passage for clothing, and on the other pegs correspondingly numbered for the overalls. Means for heating and drying the clothes should not be overlooked (see Fig. 8).
