262 RICJLUWSON'S BLUEBOOK OF PROJECTION observation ports should have two coats of flat (nongloss) black. (75) The walls and ceiling of the battery room, rewind room, motor generator room, toilet and all other rooms should be painted a light color, preferably cream or buff. The first four feet above the floor should be a dark color, which won't show finger marks and other discolorations. Port Fire Shutters (76) All port fire shutters should be of about No. 10 gauge iron. Consult your local fire authorities for any special ordinances on this subject. A fire in the projection room seldom does any extensive damage. (77) It is the sight of smoke by the audience that starts all the trouble. (78) The real purpose of port shutters is not so much to confine the Figure 72. actual fire, as it is to prevent theatre patrons knowing that there is any fire — to keep the smoke as well as the blaze entirely from their view. Shutter grooves should therefore be made to fit J:he shutters snugly but without danger of sticking. (79) The grooves should be mounted level on the wall. They should be not less than one-half inch deep, allowing the shutter one-eighth inch clearance on either side when moving up and down. Grooves may be made by using the three pieces^ of scrap iron as shown in Fig. 72, each yi of an inch thick. The three pieces are riveted together, and bolted to a level space on the wall.
