Fluorescent Aerosol Screening Test (FAST)

Pre-test photos were taken prior to wind tunnel entry. To preserve air in the tank, the SCBA regulator was not connected until immediately before wind tunnel entry. 

RTI conducted an aerosol test that found aerosol particles can penetrate a firefighter’s turnout gear and deposit on the skin.

  • A single FAST test was performed on a standard firefighter turnout gear.
  • The test ran smoothly with no significant donning, doffing, or test condition issues, with the possible exception of doffing artifacts on the hands.
  • The most prominent feature of the test was the very heavy level of aerosol deposited on the head and neck, indicating penetration of aerosol through the hood.
  • The deposits around the waist suggest infiltration through the coat-trouser interface.
  • The heavy deposits on the legs suggest infiltration through the boot-trouser interface.
