ventilation is considered satisfactory.
The work premises are kept in a constant state of cleanliness.
The floor must be made of resistant, impermeable material, and easy to
clean. When it is made slippery by the materials worked on in the
room, it shall be provided with a non-slip covering.
The different work areas must be at the same level. If this is not the
case, the inclination should be as low as possible.
The floor is cleaned thoroughly at least once a day. In rooms where
work is not organized in an interrupted day and night way, this cleaning
is carried out before the opening or after the end of work, but never
during working hours.
Cleaning shall be done either by vacuuming or washing, or with
brushes, brooms, or damp cloths if the conditions are suitable,
or wet clothes if the needs of the operation or the nature of the
floor covering prevents washing.
Where rooms are cleaned by washing, the floor should be sloped to
permit drainage and drainage systems should be provided.
Dry cleaning with brushes or brooms is strictly prohibited.
Walls and ceilings must be cleaned frequently; plastering must be
redone as often as necessary.

wide enough to protect workers against any discomfort and any
accident due to accidental contact with a machine or part of a machine.
Every establishment must have a sufficient number of doors and
stairways and, if necessary, emergency exits judiciously distributed in
order to allow a fast evacuation of the personnel and the customers in
case of fire or any other danger.
Doors, stairways, and emergency exits must always be free and never be
cluttered with merchandise in storage or any other objects.
The width of doors and stairs must not be less than 80 centimeters.

cannot justify reducing the number and width of stairways.
