However, even with the use of primary containment devices, the exterior surfaces of these suits could potentially become contaminated with those pathogens and result in their inadvertent removal from containment. To address the risk of such pathogens escaping from containment via contaminated protective suits, these suits are decontaminated in a disinfectant chemical shower situated in an anteroom prior to exiting the BSL-4 laboratory. Properly diluted chemical disinfectants such as Micro-Chem Plus™ (MCP) or peracetic acid are used for this purpose. However, whether these suits are properly decontaminated during the chemical shower process needs to be validated.Methods: The purpose of this study was to develop a suit decontamination validation method for the BSL-4 chemical showers using a risk group 2 (RG2) surrogate virus for the high consequence pathogens that are handled in the BSL-4 laboratories. Here, we evaluated the efficacy of a 5% MCP shower using coupons made from different parts of protective suits (suit fabric, visor, boot, vinyl tape) laden with a dried-on mixture of vesicular stomatitis virus in tripartite organic soil load.Discussion: This validation study demonstrated that a chemical deluge shower procedure using 5% MCP for 2 min followed by a 3-min water rinse was successful in decontaminating the positive pressure suits that were experimentally contaminated with the live RG2 virus. This offers valuable insights into the rigor of the decontamination process being undertaken in the BSL-4 laboratory chemical showers.","PeriodicalId":7962,"journal":{"name":"Applied Biosafety","volume":"29 4","pages":"241-247"},"PeriodicalIF":0.5,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11669754/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142902290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing guidelines for CL3 room leakage are often subjective, lacking a definitive standard for what constitutes a “sealed” room. Methods: This study reviews global biocontainment guidelines and standards, and it compares multiple test results from global CL3 facilities by standardizing test data to an equivalent test pressure of 250 Pa. Results: Our analysis revealed that 55% of rooms constructed using typical CL3 methodologies met the proposed testing criteria. The United States Department of Agriculture (USDA) Agricultural Research Service (ARS) greenhouse leakage rate acceptance criterion of 0.139 L/s per square meter (0.027 cfm per square foot) at a room differential pressure of 250 Pa was found to be a challenging, yet achievable standard. Conclusions: A two-step process is recommended for boundary integrity testing: (1) Initial leaks are identified using smoke pencil or soap bubble tests, followed by necessary repairs; (2) The room is then subjected to quantifiable leakage rate testing to verify it meets minimum requirements. In the absence of definitive local guidelines, we recommend the published ARS greenhouse leakage rate at a room differential pressure of 300 Pa of 0.152 L/s per square meter of surface area as an acceptable criterion for testing construction boundaries of CL3 laboratories built using current CL3 construction practices. For primary containment CL3 rooms, a more stringent criterion following the German Verein Deutscher Ingenieure guidelines at a room pressure differential of 250 Pa is noted as 0.03620 L/s per square meter of room surface area is more appropriate.","PeriodicalId":7962,"journal":{"name":"Applied Biosafety","volume":"8 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136229562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If a registered entity chooses to discontinue its registration, detailed instructions for registration withdrawal are deeply embedded within a document entitled “eFSAP Form 1 Amendment Instructions,” which is found on the FSAP website within the electronic Federal Select Agent Program (eFSAP) Resource Center. Methods: Using the information found within the eFSAP Form 1 Amendment Instructions, as well as extensive written and verbal guidance provided by the lead assigned entity point of contact at the FSAP, we completed the FSAP withdrawal process during a 12-month period between 2022 and 2023. Discussion: This commentary shares our recent professional experiences navigating the FSAP withdrawal process at the University of Texas Health Science Center at Houston (UTHealth Houston). Successes, challenges, and lessons learned are shared so that others planning or considering withdrawing may benefit from our experience. Conclusion: The resources provided for withdrawal within the eFSAP Form 1 Amendment Instructions are relatively basic, and additional details are not currently found in other FSAP guidance documents. Therefore, direct communication and support from the FSAP to the entity Responsible Officials are imperative to ensure a safe, secure, and compliant withdrawal.","PeriodicalId":7962,"journal":{"name":"Applied Biosafety","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135729062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: To evaluate the Brazilian approach to ensuring nationwide biosafety and biosecurity oversight and governance of high- and maximum-containment laboratories. Methods: A systematic gap analysis was conducted to compare Brazilian biosafety and biosecurity legislation, regulations, and policies with their international counterparts, with a particular focus on the oversight and governance of high- and maximum-containment laboratories. Results: We found that Brazilian biosafety and biosecurity legislation, regulations, and policies have relevant gaps. Governance and regulatory oversight of Brazil's high- and maximum-containment laboratories are decentralized with variable levels of adherence to commonly accepted global biosafety and biosecurity compliance standards. These findings represent a limitation not only to governance but also to the preparedness to face current and future challenges related to emergent infectious diseases in Brazil. Enhancing the Brazilian legal framework on laboratory biosafety and biosecurity is necessary and urgent. Reviewing the lessons learned and regulations applied in the United States and other international frameworks helped identify potential areas for improving Brazil's ability to inventory and manage its diverse biocontainment laboratory capabilities and assure these valuable resources align with national needs and priorities. Conclusion: The Brazilian government has an opportunity to revise and improve upon a national set of legislation, regulations, and policies for its high- and maximum-containment laboratories, taking advantage of legislation and guidelines published by other countries.","PeriodicalId":7962,"journal":{"name":"Applied Biosafety","volume":"9 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135781253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This guide was developed based on assumptions of a maximum biosafety level 2, and any chemical components present in the material were excluded from the hazard classification.Results: The guide contains necessary information to conduct a workplace risk assessment and communicate the unique workplace hazards posed by potential exposures to the material. The target audience is intended to be entities handling and producing these materials, plus collaborators, contractors, or operations sites receiving and handling the CGT material. An example of a CGT SDS is provided in Table 1.Discussion: The CGT SDS provides industry with a best practice to address an existing gap in hazard communication for CGT. We expect that, as the field evolves, so may the contents. The CGT SDS can be used as a reference for other biological modalities in the field.Conclusions: This initial CGT SDS communicates workplace hazards and assesses the unique risks posed by these biological materials and can assist in creating exposure control plans specific to the workplace hazards.","PeriodicalId":7962,"journal":{"name":"Applied Biosafety","volume":"28 3","pages":"176-191"},"PeriodicalIF":0.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10510680/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41094684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We need to better understand where this virus might be found, how much of it can spread from person-to-person, what are the effective control measures, and how to safely clean up contaminated areas.
