However, this process has also resulted in numerous safety accidents. The traditional manual supervision mode for pipeline repair processes has several limitations, including incomplete identification of risk elements and the inability to estimate risks quantitatively. To address these challenges, a safety monitoring method was put forward in this study for the visible risk elements of the gas repair operation process. This method involves the identification of five types of risk elements and the establishment of a target detection data set for gas repair operations. Moreover, a data annotation method based on mix-supervised learning is proposed, which significantly enhances data annotation efficiency and saves 50% of marking time compared with manual annotation while maintaining an acceptable level of accuracy. Additionally, a visual risk element recognition model for the gas repair process was developed by using the YOLOv5 algorithm. The test results demonstrate that the detection accuracy of the visible risk element achieved in this research is 92.9%. These findings can assist in identifying potential safety hazards for personnel, equipment, and the environment during pipeline repair operations.","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"31 3","pages":"259–267"},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140572610","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}

The methanol incident was directly caused by unsafe acts, specifically the inappropriate use of a Luer slip syringe without adjusting the position of the clamp, which remained elevated. Additionally, the incident was a result of an unsafe condition, as the safety glasses wore by the individual were not designed as over-the-glass safety glasses, creating a gap between the student’s face and lip of the safety glasses, thereby allowing methanol to reach the student’s eyes. Unsafe acts were identified as the direct causes of the ortho-chlorobenzaldehyde incident. These acts included using an inappropriate Luer slip syringe, exerting force on a long syringe needle, conducting syringe operations outside a fume hood, and neglecting to wear appropriate safety glasses and a lab coat. Furthermore, an unsafe condition involved the inappropriate positioning of a flask within a fume hood. Consequently, detaching a needle from the Luer slip syringe resulted in the scattering of chemicals reaching the student’s face and eyes. A method that enables the multifaceted exploration of the causes of human errors and facilitates the development of comprehensive solutions was used to identify 16 root causes of human errors and 11 preventive measures for the ortho-chlorobenzaldehyde incident. The lessons learned from the two incidents contribute substantially to preventing the recurrence of similar syringe incidents and reducing the risks associated with syringe operations in chemistry laboratories that handle hazardous/toxic chemicals.","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"31 3","pages":"222–228"},"PeriodicalIF":0.0,"publicationDate":"2024-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140572474","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 does not simulate a donned whole glove near the skin temperature subjected to work activity forces. Four different types of disposable nonpowdered unlined/unsupported nitrile gloves in triplicate were measured for thickness, porosity, and for the acrylonitrile content (A) of the challenge and collection sides. Limonene permeation at 35 °C through a whole glove on a clenching and nonclenching dextrous robot hand and with the standard ASTM F739 technique were facilitated by taking samples from the collection sides for GC-MS analysis. The standardized breakthrough time (SBT) when permeation reached 100 ng/cm2/min and the steady state permeation rate (SSPR) depended on A, thickness, and porosity. Only the thinnest glove (Lavender) showed statistically significant (p ≤ 0.05) increased average SSPR for the clenching hand relative to the nonclenching hand and for the ASTM technique. The ASTM test data for the three thickest gloves were not statistically different from those of the robot hand, but differed from the manufacturer’s. More research with different chemicals and higher clenching forces is needed. Clenching forces can enhance the permeation. Workers wearing ultrathin disposable nitrile gloves have a higher potential for chemical penetration/permeation. Company glove permeation data obtained near room temperature may have a longer SBT and lower SSPR than in practice. Double gloving may be advisible in emergencies and for unknown chemicals when no appropriate thicker Chemical Protective glove is available.","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"31 3","pages":"253–258"},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.chas.3c00117","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140170111","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}

The arena of cancer diagnosis and therapy has undergone a tremendous revolution since the development of nanotechnology. Due to their nanosize and biocompatibility, nanoparticles are extensively employed for gene therapy and targeted drug delivery. Nanotechnology-based approaches have also shown promising advancements in the utilization of extracellular vesicles for cancer diagnosis, prognosis, and therapy. Apart from this, the CRISPR/Cas9 (Clustered Regularly Interspaced Short Palindromic Repeats and CRISPR-associated protein 9)-based nanotherapy and the development of therapeutic nanovaccines have also demonstrated encouraging results in revolutionizing cancer treatment. Nanotechnology-based molecular imaging and contrast agents can detect cancer at very early stages, allowing for prompt treatment and better patient outcomes. Although nanoparticles offer multiple benefits for drug administration, they additionally possess certain pharmacokinetic limitations, such as body clearance, restricted tissue penetration, confrontation with biological barriers, biodistribution, and accumulation. However, improvements in nanoparticle design are intended to resolve safety issues and enhance the therapeutic effects of these particles in a variety of disease complications. While nanotechnology has demonstrated immense potential in the treatment and diagnosis of cancer, there are still several challenges to overcome, including guaranteeing the safety of nanomaterials, taking into account regulatory issues, and creating scalable and affordable solutions. Nevertheless, new developments in nanotechnology and current research hold promise for further revolutionizing cancer detection and treatment.","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"31 2","pages":"153–161"},"PeriodicalIF":0.0,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140147611","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}
