The media of HEPA filters is fragile and should not be touched. Avoid puncturing
either HEPA filter during installation or normal operation. If you suspect that a
HEPA filter has been damaged, DO NOT use the cabinet; contact a local
certification agency or Labconco at 800-821-5525 or 816-333-8811 for re-
certification information.
The HEPA filters in the biosafety cabinet will gradually accumulate airborne
particulate matter from the room and from work performed in the cabinet. The
rate of accumulation will depend upon the cleanliness of the room air, operating
time and the nature of work being done in the cabinet. The Filter Gauge
accurately displays the amount of filter life remaining.
Proper operation of the cabinet depends largely upon its location and the
ope
rator’s work habits.
Avoid direct exposure of plastic or coated materials to ultraviolet (UV) radiation.
Never bypass the UV safety interlock that only allows the UV light to work when
the sash is closed. When surface disinfecting the biosafety cabinet:
o
Avoid splashing the disinfecting solution on skin or clothing.
o
Ensure adequate ventilation.
o
Carefully follow the disinfectant’s safety instructions.
o
Always dispose of disinfecting solutions in accordance with local and national
laws.
o
DO NOT allow disinfectants with high concentrations of free chlorine to
contact the stainless steel components of the biosafety cabinet for a long
period of time. Free chlorine will corrode stainless steel after extended
contact.
Biosafety cabinets should be decontaminated for any of the following reasons:
o
Before maintenance work requiring entry into contaminated areas.
o
Before HEPA filter changes.
o
Before performing certification tests requiring entry into contaminated areas.
o
Before relocating the cabinet.
o
Before changing research programs.
o
After the gross spill of biohazardous material or toxic chemicals.
