HEPA Filter Applications, Suitability and
Guidelines
• Microbiological materials and hazardous solids containment protecting
only the operator and the surrounding environment.
• Weighing of powders.
• Containment of hazardous particulates and powders using a HEPA filter.
• Powder or particulate procedures traditionally performed on an open
bench.
• The HEPA filtered glove box provides personal and environmental
protection from particulate matter, hazardous powders and microbiological
materials.
• This glove box can be used for sample protection by reversing the
blower airflow direction, causing the main chamber to be under positive
pressure. Positive Pressure Conversion Kit is required (see Chapter 7).
• Manipulations that generate gases or vapors, i.e., toxic chemicals or
radionuclides, require the use of a HEPA and carbon filter in
combination. Otherwise the glove box should be ducted to the outside.
• Each filtered glove box is provided with two HEPA filters. Follow the
HEPA Filter change procedure in Chapter 6 for disposal instructions.
For microbiological materials, follow the Decontamination Procedure in
Chapter 6 for disposal instructions.
Safety Note: Must seal and wipe down all
chemical containers.
