Level Description Applicability
Level 1
  • Use for minimal-risk situations
  • Provides a slight barrier to small amounts of fluid penetration
  • Single test of water impacting the surface of the gown material is conducted to assess barrier protection performance
Blood draw from a vein, suturing, intensive care unit, pathology lab
Level 2
  • Use in low-risk situations
  • Provides a barrier to larger amounts of fluid penetration through splatter and some fluid exposure through soaking
  • Two tests are conducted to assess barrier protection performance:
    • Water impacting the surface of the gown material
    • Pressurizing the material
Blood draw from a vein, suturing, intensive care unit, pathology lab
Level 3
  • Use in moderate-risk situations
  • Provides a barrier to larger amounts of fluid penetration through splatter and more fluid exposure through soaking than level 2
  • Two tests are conducted to assess barrier protection performance:
    • Water impacting the surface of the gown material
    • Pressurizing the material
Arterial blood draw, inserting an I.V., emergency room care, trauma care
Level 4
  • Use in high-risk situations
  • Prevents all fluid penetration for up to 1 hour
  • May prevent virus penetration for up to 1 hour
  • In addition to the other tests conducted under levels 1-3, barrier level performance is tested with a simulated blood containing a virus. If no virus is found at the end of the test, the gown passes.
Pathogen resistance, infectious diseases (nonairborne), large amounts of fluid exposure over long periods
