17、tent guidance with regard to the respira-tor fit testing components of an effective respiratory protection program. The respirator fit test itself is simply one facet of fit testing. An effective program requires muchmore, including a qualified person to perform the fit test. This standard provides
18、guidance on exactlywhat knowledge and skills are necessary in order to perform as a qualified fit test operator.This standard contains information to aid program managers and fit test operators in preparing toperform a proper fit test. This includes guidance regarding potential interference from oth
19、er person-al protective equipment with the respirator, detailed information on respirators used for fit testing,selection of respirators prior to fit testing, and other considerations that must be met if the fit test isto be effective.A single fit test exercise protocol cannot model all workplace ac
20、tivities encountered by respiratorusers. Recognizing this, the standard provides flexibility regarding fit test exercise protocols.Exercises may be selected that are more representative of actual workplace activities, includingrepeated respirator donning. Annex A1 is informative and is not considere
21、d part of the standard. Annex A2 is mandatory for future inclusion of new fit test methodologies into this standard.Annex B is informative and is not considered part of the standard.Suggestions for the improvement of this standard are welcome.

33、Fit factor: A numeric expression of howwell a tight-fitting respirator fits a wearerduring a quantitative fit test. It is the ratioof the measured challenge agent con-centration outside the respirator (Cout) toits concentration inside the respirator(Cin). (Fit factor = Cout/ Cin). 3.9 Fit test: The

This standard provides guidanceon how to conduct fit testing of tight-fit-ting respirators and appropriate methodsto be used. Fit testing is only one ele-ment of a complete respiratory protectionprogram. E
35、xamples of complete respira-tory protection programs are defined inANSI Z88.2, 29 CFR 1910.134 (OSHA),etc.1.2 Purpose. This standard providesrequirements for conducting respirator fittesting and includes: qualifications for fit test operators specific fit test methods interpretation of fit test resu

Other sourcesof leakage may contribute to the totalleakage detected.1.3 “SHOULD and SHALL.” The provisionsof this standard are mandatory in naturewhere the word “shall” is used

42、.3.17 Tight-fitting respirator: A respirator witha facepiece, hood or helmet that isdesigned to form a complete seal withthe face or neck. This includes a hood orhelmet with a neck seal (neck dam).3.18 User seal check: A procedure conduct-ed by the wearer to determine if a tight-fitting respirator i
43、s properly donned. 4 Fit Testing RationaleThe purpose of respirator fit testing is toverify that the selected make, model, andsize of a tight-fitting respirator adequatelyfits the wearer. This is accomplished sothere is reasonable assurance that thewearer has learned to don the respiratorproperly an
44、d can achieve the anticipatedprotection during use. Fit testing is a criti-cal component of a respirator trainingprogram.5 Qualifications of Fit Test Operators5.1 General Qualifications. Fit test opera-tors shall be properly trained and demon-strate a proficiency in the fit testmethod(s) being used.
45、 The respiratoryprotection program administrator isresponsible for evaluating and verifyingthe training and qualification of operators.Program administrators may wish to con-sider the benefits of formal training pro-grams from outside providers for fit testoperators. An evaluation form for fit testo
46、perators is in Annex A1. Continue train-ing fit test operators until all questions onthe form can be marked “acceptable” bythe evaluator. Determination of accept-ability for each item is left to the discre-tion of the respiratory protection programadministrator.5.2 Specific Qualifications for Fit Te
