CAUTIONS
* The use of any hazardous material in the cabinet requires that it be monitored by an industrial
hygienist, safety officer or other qualified individual.
* Explosive or flammable substances should never be used in the cabinet unless a qualified safety
professional has evaluated the risk.
* If hazardous biological work is to be performed, apply the enclosed biohazard decal. This is in
accord with OSHA regulations (volume 39, number 125, Part II).
* If chemical, radiological or other non-microbiological hazards are present, be sure to employ
appropriate protective measures. Call upon a suitably trained individual to monitor the
operation.
Location Within the Laboratory
The ideal location for any biological safety cabinet is in a dead-end corner of the laboratory away from
personnel traffic, vents, doors, windows and any other sources of disruptive air currents. Published research
from The Baker Company and unpublished tests performed at the National Cancer Institute show that if a
draft or other disruptive air current were to exceed the intake velocity of the cabinet, contamination can enter
the work area or escape from it (for more information, contact Baker).
Proper placement within the
laboratory is essential.
If the cabinet exhausts air into the laboratory instead of venting to the outside, it is important that there is
adequate space between the top of the cabinet and the ceiling. A solid ceiling located too close to the
exhaust filter will restrict the air and limit the intake velocity. The exhaust filter guard, an inverted “V”
shaped perforated steel plate included with your cabinet, will provide the necessary distance between
exhaust opening and ceiling. If the filter guard is not installed, the cabinet exhaust opening should be no
closer than 2-¾” from the ceiling, to enable proper airflow. Consult with our Customer Service Department
for the implications of this and for alternatives.
Installing the Cabinet
Installation of this cabinet should be carried out in accordance with appropriate OSHA regulations and those
of other regulatory agencies having jurisdiction.
1.
Remove the protective container from around the cabinet.
2.
Remove the strapping that holds the cabinet to the pallet.
3.
Remove the tape that secures the viewscreen, work surface and diffuser.
4.
The small cardboard box taped to the work surface contains the drain valve and the exhaust filter guard.
5.
If cabinet exhausts its air directly into the laboratory instead of ducting it to the outside, install the
exhaust filter guard on top of the exhaust damper using the two wing nuts installed on the damper.
6.
The drain valve must be installed before the cabinet is either installed on the stand or placed on a counter
top.
