workshop or workplace not already under the operation of any general
act for the regulation of factories or bakehouses not kept in a
cleanly state or not ventilated in such a manner as to render harmless
as far as practicable any gases, vapours, dust or other impurities
generated in the course of the work carried on therein that are a
nuisance or injurious to health, or so overcrowded while work is
carried on as to be dangerous or injurious to the health of those
employed therein; (7) any fireplace or furnace which does not as far
