fatty acid salts; not -cidal or -static but by mechanical removal
BSL-3

microbes are indigenous/exotic and cause lethal diseases thru respiratory
transmission
-BSL-2 and respirator, bio safety cabinets, hands-free wash sink, two sets of
doors (ex. none at UTA)
-ex. Mycobacterium tuberculosis

generally not a sterilization method but "static"; slows metabolism but will
grow when temps. are raised; reason why USDA recommends thawing at
temps. lower than optimal

living or fomites, depending on safety
BSL-4

- Microbes are dangerous & exotic, posing a
high risk of aerosol‐transmitted infections, which are frequently fatal w/o
treatment or vaccines. Few labs are at this level
-BSL-3 and full biohazard suit, shower on exit, lab must have own air supply
(only 13 in USA)
-ex. Ebola and Marburg viruses
