PROPER CABINET USE
A biological safety cabinet is a valuable
supplement to good sterile technique, but is not a
replacement for it. If the cabinet is not
understood and operated correctly, it will not
provide an adequate protective barrier.
All activities that
are
to be performed in your
cabinet should first be approved by a competent
professional, such as an industrial hygienist or
safety officer, to make sure that the cabinet is
appropriate for the work it wiJl be required to do.
This person should monitor the cabinet and its
operating personnel at regular intervals to see that
it is being used correctly.
ln order to keep the interior workspace clean
and free of particulates, all Baker laminar flow
cabinets are designed for continuous operation. If
the blower is turned off, the unit becomes
contaminated with room air. Therefore it is
recommended that the blower be left on.

For normal operation, the viewscreen must be
placed to allow an opening of exactly 8." This
setting is important to allow the correct airflow

above the alarm reset switch will flash.

five minutes, the alarm will sound again to
remind you to lower the window. You may press
the alarm reset switch again to mute the alarm for
