Tracy M. Mattox; Anne L. Pham; Michael D. Connolly; Liana M. Klivansky; Rohan Dhall; Jeffrey J. Urban – Journal of Chemical Education, 2023
Laboratory chemical synthesis research typically lacks the preplanned hazard responses found in production-scale industrial laboratories. Chemical safety management is a known challenge in education-based facilities, which is concerning for academic and national laboratory environments working with inexperienced student researchers. At the…

Yongguang Gao; Na Chen; Xiaoye Jiang; Xiaochun Yang – Journal of Chemical Education, 2024
The substitution of carbonyl compounds with liquid bromine as a brominating agent is the most commonly employed synthesis method for a-bromoacetophenone and its derivatives. However, liquid bromine possesses certain drawbacks, such as volatilization, high toxicity, strong corrosion, and poor reaction selectivity, which limit its application and…

Hunter, Kirk P.; Hill, Robert H., Jr.; Gmurczyk, Marta – Journal of Chemical Education, 2021
Chemical safety is a discipline that cuts across all other chemical disciplines and also impacts other laboratory sciences. It is an essential part of chemistry and continues to evolve with the science it supports. This paper provides a short background about ACS's growing involvement with chemical safety education that stems from support from ACS…

Ng, Enoch Ming Wei; Song, Zhixiong; Yau, Chin Doong; Liew, Oi Wah; Ng, Tuck Wah – Journal of Chemical Education, 2021
The reaction between hydrochloric acid and calcium carbonate to produce carbon dioxide gas is a popular and engaging experiment to illustrate chemical reactions that result in the production of gases. It also provides a useful model for teaching concepts related to the effects of concentration on reaction rates. Although a prepared hydrochloric…

Axel Milne – Journal of Chemical Education, 2022
High-voltage plasma arcs from solid-state Tesla coils were used to produce characteristic atomic emissions of various metals. The colored arcs produced were highly visible and vibrant, making for a spectacularly engaging demonstration for groups of varying sizes. The demonstration used an inexpensive solid-state Tesla coil to generate low-current,…

Schwenz, Richard W. – Journal of Chemical Education, 2021
Among the tasks that the ACS Committee on Professional Training undertakes is the periodic revision of the "ACS Guidelines and Evaluation Procedures for Bachelor's Degree Programs" (also known as "the guidelines"). Because the guidelines recommend and/or mandate practices for the safe education of undergraduate students,…

Ngai, Eugene; Ngai, Courtney – Journal of Chemical Education, 2021
Academic institutions are faced with the complex problem of accurately determining the hazards associated with a proposed or ongoing project. For many reasons, compressed gas safety can be a significant challenge at universities, especially those that involve research using many uncommon materials. This article is a call to action for implementing…

Espinasse, Adeline; Jayaraman, Ashish; Reisbick, Spencer A.; Harris, Celina M.; Kou, Yangming; Xu, Hongyun; Anderson, Constance B.; Bader, Taysir K.; Sitek, Anna A. – Journal of Chemical Education, 2021
The Joint Safety Team (JST) was conceived in 2012 by the Departments of Chemical Engineering and Materials Science and Chemistry at the University of Minnesota and the Dow Chemical Company as a model student-led safety organization. The JST initiative was aimed at improving academic safety through four core areas: compliance, awareness, resources,…

Shaw, Nicholas N.; Sigmann, Samuella B.; Richard, Lyndsay B. – Journal of Chemical Education, 2021
Working with undergraduates in an organic synthesis research laboratory presents a unique set of challenges. An undergraduate research program must be designed to focus on teaching students to "think like a chemist" while advancing the principal investigator's scientific agenda. However, as novices in the laboratory, undergraduate…

Mulford, Douglas R. – Journal of Chemical Education, 2021
The liquid nitrogen cloud demonstration is an effective, dramatic, large-scale demonstration to illustrate gas laws and cloud/fog (aerosol) formations for classes and large-scale outreach events. When performed at full scale, it is common to produce a cloud 20-30 feet in height. Its effect can be further enhanced by adding brightly colored…

Thomsen, Trine; Borre-Gude, Stefan – Journal of Chemical Education, 2021
In this article, a proven safety concept with documented success is presented. The concept aligns with best safety practices and the international engineering educational framework termed "The CDIO Initiative," and it has resulted in a strong safety culture among students and staff. This concept has been developed for undergraduate…

Sigmann, Samuella B. – Journal of Chemical Education, 2021
In 2015, "NFPA 45, Standard on Fire Protection for Laboratories Using Chemicals," from the National Fire Protection Association (NFPA) was updated to include language requiring educators to perform a documented risk assessment when conducting demonstrations in K-12 classrooms. Additionally, in the past five years numerous organizations…

Delgado, Sergio Nogales; Martín, José María Encinar; Suero, Silvia Román – Journal of Chemical Education, 2021
One of the most general aims of universities is to respond to the requirements of society. Health and safety are the most important aspects of professional work and play an important role in universities, as there, future professionals are trained for their future professional life. Scientific and technical degrees require adaptation to this…

Hill, Robert H., Jr. – Journal of Chemical Education, 2021
Developing strong safety cultures in academic institutions requires that students at all levels be educated by faculty in chemical safety. Yet chemical safety education is missing from the chemistry curriculum. This article considers a report of numerous injuries from incidents from using flammable chemicals in demonstrations as evidence that…
