3、nvolved in treating and caring forindividuals injured or sick,can be exposed to biological liquids capable of transmitting disease.Thesediseases,which may be caused by a variety of microorganisms,can pose significant risks to life andhealth.This is especially true of blood-borne viruses which cause
4、Hepatitis(Hepatitis B Virus(HBV)and Hepatitis C Virus(HCV)and Acquired Immune Deficiency Syndrome(AIDS)HumanImmunodeficiency Virus(HIV).Because engineering controls can not eliminate all possibleexposures,attention is placed on reducing the potential of direct skin and mucous membrane contactthrough
5、 the use of protective clothing that resists penetration(29 CFR Part 1910.1030).This testmethod was developed for ranking the synthetic blood penetration resistance performance of medicalace masks in a manner representing actual use as might occur when the face mask is contacted by ahigh velocity st
6、ream of blood from a punctured wound.1.Scope1.1 This test method is used to evaluate the resistance ofmedical face masks to penetration by the impact of a smallvolume(2 mL)of a high velocity stream of synthetic blood.Medical face mask pass/fail determinations are based on visualdetection of syntheti
7、c blood penetration.1.2 This test method does not apply to all forms or condi-tions of blood-borne pathogen exposure.Users of the testmethod must review modes for face exposure and assess theappropriateness of this test method for their specific applica-tion.1.3 This test method primarily addresses
8、the performance ofmaterials or certain material constructions used in medical facemasks.This test method does not address the performance ofthe medical face masks design,construction,or interfaces orother factors with the potential to affect the overall protectionoffered by the medical face mask and
9、 its operation(such asfiltration efficiency and pressure drop).Procedures for measur-ing these properties are contained in Test Methods F2101 andMIL-M-36954C.1.4 This test method does not address breathability of themedical face mask materials or any other properties affectingthe ease of breathing t
