This empirical study utilizes the “Enhancement of Safety Practice in Research Laboratory in Thailand” (ESPReL) checklists to identify safety problems focusing on three aspects: the chemical management system; the waste disposal system; and laboratories, equipment, and tools. The experiment gathers safety evaluation reports from 17 educational buildings with laboratories located on a university campus. The methodology includes various procedures, including walk-through observations, documentation, user interview, specialist evaluation, and stakeholders’ data verification. Finally, all the analyzed data identified common safety problems and reviewed existing mitigation plans. The finding shows common laboratory safety problems in laboratories, equipment, and tool components, where both specialists’ and laboratory users’ assessments indicate significant concerns that indicate the need for urgent improvement. In addition, the difference in results between the two parties’ evaluation occurs in some aspects, suggesting the enhancement in integrating the laboratory safety rules and guidelines into safer user habits. In conclusion, the study highlights the necessity to improve laboratories’ physical attributes and facility design, as well as refurbish the building engineering systems and safety equipment to the current building standards. Moreover, the safety awareness gap is another issue that should not be overlooked. Further study suggests investigating facility management or user-behavior effects to narrow down the gaps to improve safety in academic laboratories.","PeriodicalId":12,"journal":{"name":"ACS Chemical Health & Safety","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2022-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"557916","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}

Had the reactor pressure vessel ruptured, a major public safety event would have occurred. Further investigations revealed that, by the end of 2001, a shutdown order was drafted by the Regulatory Agency. Nonetheless, through a risk-informed decision-making approach, the Agency changed the decision related to the issuance of the order. Operations were then allowed to continue for six more weeks, despite the high likelihood that the reactor was operating with leaking cracks in the nozzles located at the reactor head. The reactor vessel head wastage, which had evolved unnoticed for years, was primarily due to borated water that leaked through a nozzle crack onto the carbon steel portion of the reactor head, resulting in boric acid corrosion. This paper aims to explore the Agency’s decision-making to identify factors that might have contributed to the flawed decision. A better comprehension on the organizational factors and social processes that can adversely affect risk-informed decisions is crucial to enhance operational safety in high hazard industries. The paper concludes by suggesting possible ways to guard against the identified factors.","PeriodicalId":12,"journal":{"name":"ACS Chemical Health & Safety","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2022-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"555282","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}

Healthcare workers and other medical first responders in particular need personal protective equipment to protect their respiratory system from airborne particulates, in addition to liquid splashes to the face. N95 respirator have become a critical component for reducing SARS-CoV-2 transmission and controlling the scale of the COVID-19 pandemic. However, a major dispute concerning the protective performance of N95 respirators has erupted, with a myriad of healthcare workers affected despite wearing N95 masks. This article reviews the most recent updates about the performance of N95 respirators in protecting against the SARS-CoV-2 virus in the present pandemic situation. A brief overview of the manufacturing methods, air filtration mechanisms, stability, and reusability of the mask is provided. A detailed performance evaluation of the mask is studied from an engineering point of view. This Review also reports on a comparative study about the protective performance of all commercially available surgical and respiratory masks used to combat the spread of COVID-19. With the aim of protecting healthcare providers more efficiently, we suggest some potential directions for the development of this respiratory mask that improve the performance efficiency of the mask.","PeriodicalId":12,"journal":{"name":"ACS Chemical Health & Safety","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2022-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"470891","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}

When using these devices, the presence of sharp tips poses a risk of puncture wounds and increases the likelihood of chemical exposure. While these devices are regularly used in chemistry, facts on their proper usage, as well as the prevention of injuries, are scarce in the literature. Needle injuries often reflect inadequate hands-on training in their use during chemical transfer procedures, incorrect recapping, and improper storage and disposal procedures. Preventing needle injuries in the lab requires having situational awareness which is achieved by using proper techniques and a proper reaction set up, performing a risk assessment, and having group discussions about the procedure. As in all chemical manipulations, it is critical to be familiar with the reaction setup, to receive the necessary training for the chemicals being used, and to have reviewed all associated standard operating procedures (SOPs). Thorough planning can reduce injuries and exposures incurred by students and other researchers. This paper will discuss safe techniques for the use of needles and cannulas in chemistry laboratories.","PeriodicalId":12,"journal":{"name":"ACS Chemical Health & Safety","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2022-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"573058","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}
