A severe disease caused by Streptococcus pyogenes that causes a type of toxic shock syndrome and produces enzymes that destroy proteins and allow the bacteria to invade the human epithelial cells; also referred to as flesh-eating bacteria and group A, beta-hemolytic streptococcus. The infection moves along the fascia (membrane covering of the body under the skin, as well as the various muscle groups); may also be caused by Staphylococcus aureus, vibriovulnificus, clostridium perfringens, and Bacteriodes fragilis.

NIOSH required test for N95 respirators that measures filter efficiency and penetration of a 0.3 um sodium chloride particle aerosolized at a flow rate of 85 liters per minute, requiring a 95% filtration efficiency. OSHA requires that all respirators be properly fit tested using a quantitative or qualitative fit test when initially assigned to a user, and periodically thereafter. A user seal check should be performed each time a respirator is put on.
