Respiratory Protection in a Time of Crisis: NIOSH Testing of International Respiratory Protective Devices for Emergency Use.
Andrews AS , Powers JR Jr , Cichowicz JK , Coffey CC , Fries ML , Yorio PL , D'Alessandro MM . Health Secur 2021 19 (4) 379-385 National Institute for Occupational Safety and Health (NIOSH)-approved respirators are required by the Occupational Safety and Health Administration (OSHA) when personal respiratory protection is used in US occupational settings. During the COVID-19 pandemic, the demand for NIOSH-approved N95 filtering facepiece respirators overwhelmed the available supply. To supplement the national inventory of N95 respirators, contingency and crisis capacity strategies were implemented and incorporated a component that endorsed the use of non-NIOSH-approved respiratory protective devices that conformed to select international standards. The development and execution of this strategy required the collaborative effort of numerous agencies. The Food and Drug Administration temporarily authorized non-NIOSH-approved international respiratory protective devices through an emergency use authorization, OSHA relaxed their enforcement guidance concerning their use in US workplaces, and NIOSH initiated a supplemental performance assessment process to verify the quality of international devices. NIOSH testing revealed that many of the non-NIOSH-approved respiratory protective devices had filtration efficiencies below 95% and substantial inconsistencies in filtration performance. This article reports the results of the NIOSH testing to date and discusses how it has contributed to continuous improvement of the crisis strategy of temporarily permitting the use of non-NIOSH-approved respirators in US occupational settings during the COVID-19 pandemic. |
A General Framework to Test and Evaluate Filtering Facepiece Respirators Considered for Crisis Capacity Use as a Strategy to Optimize Supply.
Yoon KN , Greenawald LA , Rottach DR , Pollard JP , Yorio PL . J Int Soc Respir Prot 2020 36 (1) 36-51 During a public health emergency, respirator shortages can have a profound impact on the national response, such as for the current coronavirus disease 2019 (COVID-19) pandemic. Due to a severe shortage of respirators (particularly filtering facepiece respirators [FFRs]), there may be contexts in which understanding the performance of FFRs that are approved for use as part of a crisis capacity strategy is desired. This includes FFRs that are not covered under the National Institute for Occupational Safety and Health (NIOSH) Respirator Approval Program because they have been stored past their designated shelf life, have been decontaminated, or are approved by international certification bodies other than NIOSH. The purpose of this document is to provide a general framework to assess the performance of FFRs that are only being used as a crisis capacity strategy. The intended audience are those who are responsible for managing large amounts of FFRs. This framework includes a four-step process consisting of: 1) defining the population of FFRs to be sampled; 2) providing sampling strategy options; 3) inspecting and testing the sampled units; and 4) evaluating the results. In addition to the four-step process, we provide an example of how NIOSH recently evaluated the quality of FFRs sampled from ten U.S. stockpiles. |
Health and safety management systems through a multilevel and strategic management perspective: theoretical and empirical considerations
Yorio Patrick L , Willmer Dana R , Moore Susan M . Saf Sci 2014 72 221-228 Multilevel and strategic management theory and research methods are presented and applied to current issues in occupational health and safety (HS), the primary goal being to better understand health and safety management systems (HSMS) from a theoretical and empirical perspective. Through these perspectives, a strategic HSMS may be understood as a construct that exists objectively at the strategic level of the organization-its objective content often distinct from the implemented practices and procedures within a workgroup and from worker perceptions and interpretations of its content. These nuances highlight the types of biases that can arise when choosing a level of measurement to assess the HSMS and techniques that can be used to minimize measurement error and increase the validity of inferences made. These nuances also illuminate the contingencies important for the success of a strategic organizational HSMS. The contingencies are discussed from a theoretical perspective and presented in a conceptual HSMS model. |
