This study investigated the potential of radiofrequency identification (RFID) technology, currently used for hazardous chemical inventory, in applications with higher metal interference and absorption, specifically pressure release device (PRD) compliance and nuclear container management, at Lawrence Livermore National Laboratory (LLNL). This study was done to document best practices to enhance inventory identification speeds for inventory reconciliation and inventory recall and to explore optimal configurations for RFID implementation compared to traditional manual methods of equipment management. Tests were conducted to determine the ideal RFID tag orientation (read at angles of 0°, 90°, and 270°), various container layouts (linear, separated, curved, operational), and ID methods such as manual, barcode, and RFID performing three trials per method per orientation. Results indicated that 0° was the optimal read angle for minimizing metallic interference, and the operational and curved arrangements significantly outperformed the linear and separated configurations in read speed. 3D printed mounts were developed and tested, increasing the read range of the RFID reader by up to 235% in cases of high metallic interference. The RFID technology demonstrated an average speed increase of 65% over a simplified manual identification, which supports the conclusion that RFID is a more efficient method for large hazardous inventory management and equipment reconciliation. Additionally, capturing meta-data, such as location and date, can be used to query for inventory recall and automated updating of record information.</p>","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"32 1","pages":"30–38 30–38"},"PeriodicalIF":0.0,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143087561","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}

Volatility data are particularly important for chemists, engineers, occupational health and safety staff, and warehouse personnel. The initial zero-order kinetic phase is a useful parameter that allows defining fire protection measurements harmonized with the volatility of products. The extent of this kinetic regime is determined by the initial fraction of the more volatile components in the bulk liquid materials. Qualitative mechanistic considerations are included for the evaporation kinetics of twenty-three products studied (industrial solvents and a heat transfer material, auto fuel additives, household products, and liquors), as examples of the procedure when volatility data are missing in safety data sheets, and educated assumptions must be resorted to.

This review examines the challenges posed by legacy chemicals in research institutions, categorizing them into four main types: old commercial chemicals, rebottled chemicals, research samples, and chemical-containing instruments. These chemicals create significant problems, including numerous safety hazards and financial costs. The origins of legacy chemical accumulation are introduced, such as overpurchasing and researchers leaving without proper cleanup. Strategies for addressing existing legacy chemical issues are presented. Approaches to prevent future accumulation include implementing robust institutional policies, maintaining accurate inventories, ensuring proper labeling, and establishing clear off-boarding procedures for researchers. The importance of a proactive, cradle-to-grave approach to chemical management in research settings is emphasized. By sharing experiences and approaches, the aim is to assist other institutions facing similar challenges with legacy chemicals and potentially apply these concepts to other research materials, such as biological samples.</p>","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"32 1","pages":"16–21 16–21"},"PeriodicalIF":0.0,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.chas.4c00102","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143084234","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}

Cellulosic materials are highly flammable and release harmful gases during combustion. Conventional flame retardants may pose environmental and health risks while impacting the fabric quality. GCS extract is a rich source of tannins, phosphorus, silicates, metallic salts, and oxides and is explored as a novel flame retardant (FR) for cotton fabrics. Cotton samples were pretreated with PA and then with varying concentrations of GCS extract using a padding technique. Comprehensive characterization followed, including limiting oxygen index (LOI), thermogravimetric analysis (TGA), derivative thermogravimetry (DTG), burning time tests, scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) analysis, Fourier-transform infrared spectroscopy (FTIR), tensile strength, and wash durability assessments. The treated samples exhibited improved flame resistance properties, with LOI values increasing from 18 to 29.5. TGA results indicated enhanced thermal stability, while FTIR analysis confirmed higher phenolic hydroxyl content in treated samples. SEM imaging verified GCS extract deposition and EDX analysis revealed key elements such as Na, Al, P, S, K, and Ca on the treated surfaces. The combination of GCS extract and PA offered a sustainable and effective flame-retardant solution for cellulosic fabrics.

This study investigated the chemical composition of bulk dust particles generated during the roughing and buffing processes of making parchment, aldehyde, aldehyde-formaldehyde, and vegetable-tanned leather processes in a local tannery. The study focused on the analysis of aldehydes (formaldehyde, acetaldehyde, acrolein and glutaraldehyde) and various preservative agents (<i>p</i>-chloro-<i>m</i>-cresol (PCMC), <i>ortho</i>-phenylphenol (OPP), 2-(thiocyanomethylthio)benzothiazole (TCMTB), octylisothiazolinone (OIT), and diiodomethyl-<i>p</i>-polysulfone (DIMPTS)) in the bulk dust samples using high-performance liquid chromatography (HPLC). The results revealed varying concentrations of these chemicals across the samples, with aldehyde-formaldehyde-tanned leather bulk dust containing the highest formaldehyde levels (409.2 ppm). Parchment bulk dust recorded the highest acetaldehyde concentration in all samples (1.8 ppm), while vegetable-tanned leather bulk dust recorded the highest acrolein and glutaraldehyde content (13.2 and 3.7 ppm, respectively). Aldehyde-tanned leather bulk dust recorded the highest concentrations of PCMC (159.6 ppm) and DIMPTS (136.7 ppm). No detectable levels of OPP, TCMTB, or OIT were recorded in any of the samples. The concentrations of formaldehyde, PCMC, and DIMPTS reported in this study highlight the need for personal and environmental sampling in order to understand the health risks posed to workers in these environments.
