    There are additional specific rules and designations for animal research (ABSL), agricultural research (BSL-Ag), and other types of research..

  • Why use biosafety cabinets?

    Biological safety cabinets (BSCs) are used to protect personnel, products and the environment from exposure to biohazards and cross contamination during routine procedures..

Things to remember when placing biological safety cabinets
  • Air supply diffusers or exhaust vents should not be placed directly over or in front of BSCs.
  • BSCs should be located out of the laboratory personnel traffic pattern. Preferably they are placed at the end of an aisle.
  • BSCs should not be placed near an entryway.
