  2. Respirator fit test - Wikipedia

    en.wikipedia.org/wiki/Respirator_fit_test

    The main advantage of qualitative fit test methods is the low cost of equipment, while their main drawback is their modest precision, and that they cannot be used to test tight-fitting respirators that are intended for use in atmospheres that exceed 10 PEL (due to the low sensitivity). To reduce the risk of choosing a respirator with poor fit ...

  3. NIOSH air filtration rating - Wikipedia

    en.wikipedia.org/wiki/NIOSH_air_filtration_rating

    NIOSH air filtration ratings do not test the fit of a respirator. Fit testing is required by OSHA for employers when a hazard is present, and voluntary respirator use under Appendix D is not allowed due to the hazard. [31] Rules for fit testing are also defined by ANSI Z88.2. Z88.2 notes that, in Canada, respirator care and fit testing are ...

    A study found that 80–100% of subjects failed an OSHA-accepted qualitative fit test, and a quantitative test showed between 12 and 25% leakage. [ 46 ] A CDC study found that in public indoor settings, consistently wearing a respirator was linked to a 83% lower risk of testing positive for COVID-19, as compared to a 66% reduction when using ...

  5. Fault tree analysis - Wikipedia

    en.wikipedia.org/wiki/Fault_tree_analysis

    A fault tree diagram. Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident or a particular system level ...
