clear of the access to any exit.
(35)-(a) The projector and the illuminant shall be entirely enclosed in a casing of fire-resisting material except for such openings as are necessary for effective manipulation and ventilation.
(b) Any electric wiring or terminals fitted within the casing shall be so placed that it shall be impossible for films in use in the projector to come in contact with them.
(c) Each electric circuit on the projector shall be fitted with a separate switch controlled from outside the casing, and so placed as to be within reach of the operator when standing at the projector.
