VENTILATION An open window does not
provide adequate ventilation when working with
hazardous art materials. When working with
these materials, you should have an exhaust
ventilation system (one which removes vapors,
dusts, etc., from the area in which you
are working and vents to the outside). A general
ventilating system dilutes toxic vapors with fresh
air to lower their concentration to a
safer level.
Many factors have to be considered to determine
the kind of ventilating system you should have.
RESPIRATORS A respirator may pose more of a
hazard than a help unless:
• you get one designed to filter out the specific
hazardous substance you are working with
• one that fits properly
• you keep it properly cleaned and maintained.
