[Illustration: FIG. 8 shows a good arrangement in a white-lead factory, by which, as is best, cloakroom, meal-room, and washing and bath accommodation, are all under one roof. The men on entering hang up their clothes in the private clothes lobby, and pass through the swinging doors to the lobby where the overalls are hung. On leaving the factory and at midday they enter by the door leading into the lobby for storing overalls, and from that pass to the lavatory and bathroom. Having washed and put on their ordinary clothes, they enter the meal-room. The building throughout is lined with white glazed bricks.] [Illustration: FIG. 8A.--WELL LIGHTED MESS-ROOM IN A SMELTING WORKS.] =Meal-Room Accommodation.=--Wherever lead processes are carried on the provision of a mess-room is called for in a part of the factory remote from possible contamination from lead dust. This we hold on general grounds of cleanliness and self-respect, and not because we think the eating of meals in rooms where lead is used would noticeably increase the number of cases. The more conveniently situated in relation to the workrooms the mess-room is, the more will it be used. Set out briefly, the requirements of a mess-room are that it should be-- 1. Well ventilated, warmed, and lighted. 2. Not less than 10 feet high, and with floor-space ample for each person likely to occupy it at any one time. 3. Have walls the surface of which is smooth and impervious to a height of at least 4 feet from the ground. 4. Have pigeon-holes or other arrangement in which each person can deposit his food separate from that of others. 5. Have means of warming and cooking food. 6. Be kept properly clean and dry. No part of a factory becomes so unsightly in the absence of daily cleaning as a mess-room, especially where provision has only to be made for five or six workers. Reid[1] has suggested the following scale of floor-space per person in mess-rooms: 6 persons and under 10¹⁄₂ square feet per person. Over 6 and up to 12 7¹⁄₂ „ „ „ „ 12 „ 20 6 „ „ „ „ 20 „ 28 5¹⁄₂ „ „ „ „ 28 and any number 5 „ „ „
