4 .2 Cabinet Operating Procedure
•
The fume hood should only be operated with the correct filter installed for the application. Refer to Filter
Information for further information. The ductless fume cabinet must not be used for laboratory work in
which chemicals of different types are used that do not match the filter type or that the primary chemicals or their
byproducts are not known
. The ductless fume cabinet should not be used for different chemical processes where
chemicals from the different processes could react in the filter.
•
To start the system, apply power to the system and switch on the green power On/Off switch
. The lights will
automatically switch on as will the fan
.
•
Check the airflow and the filter condition of the cabinet on a regular basis. This is covered in Maintenance.
•
Please note, filter blocks do not absorb carbon monoxide or hydrogen. Small quantities will not cause hazards
because of the large dilution factor from the amount of air passing through the cabinet and the retardation of
the chemical in the filter matrix.
•
Cole-Parmer fume hoods have been designed to handle fumes and vapors given off during everyday laboratory
procedures. These will be at the parts per million (PPM) level in the air stream entering the filter block. It is not
recommended that large quantities of solvents or acids be used or boiled off in the cabinet
.
•
In the event of a large spillage in the cabinet, the level of fumes entering the filter block may temporarily reduce
the efficiency of the filter. For this reason any major spillage must be cleared up immediately, preferably using
spillage absorption granules rather than paper, which may aggravate the evaporation of toxic fumes from the
spillage area
.
•
Following a major spillage, the filters must be changed as the heat of wetting may reduce the efficiency of the
filter. After a period of stabilization, the old filters may be reused, providing they have not reached the saturation
level.
•
Ensure the electrical equipment in the cabinet such as the lights and controls are not in the dirty air stream of the
system. The system should not be used in a flammable room atmosphere. Special modified cabinets can be
provided for use in these areas. Contact Cole-Parmer for further information on these applications.
•
Operators should avoid sudden movements within the fume cabinet, such as rapid opening or closing of the
sash window, as this may cause temporary reversal of the airflow.
•
Operators should maintain the normal safety equipment and procedures for dealing with
hazardous chemicals
.
WARNINGS!
»
Do not use a gas flame (Bunsen burner) whenever possible, as it interferes with airflow.
»
Do not change original blower speed of the cabinet unless the change is required by a decrease in measured
air velocity. Adjustment should be made only by a qualified technician. Do not operate the cabinet if fan fails
to run
.
»
Minimize arm movement. Move arms in and out of the cabinet slowly to avoid disrupting cabinet airflow.
»
Use absorbent pads on the work surface where appropriate to minimize splatter and aerosol generation in case of
spillage.
»
Keep lids/covers on all containers, dishes and sample plates.
