JCHAS Spotlight: Ergonomics of Glove Boxes

The Editor’s Spotlight for the July / August 2017 issue of the Journal of Chemical Health and Safety is shining on:

Rotator cuff strength balance in glovebox workers (link to PDF version)

By Cindy M. Lawton, Amelia M. Weaver, Martha K.Y. Chan, Michael E. Cournoyer

The abstract is:

Gloveboxes are essential to the pharmaceutical, semi-conductor, nuclear, and biochemical industries. While gloveboxes serve as effective containment systems, they are often difficult to work in and present a number of ergonomic hazards. One such hazard is injury to the rotator cuff, a group of tendons and muscles in the shoulder, connecting the upper arm to the shoulder blade. Rotator cuff integrity is critical to shoulder health. This study compared the rotator cuff muscle strength ratios of glovebox workers to the healthy norm. Descriptive statistics were collected using a short questionnaire. Handheld dynamometry was used to quantify the ratio of forces produced for shoulder internal and external rotation. Results showed this population to have shoulder strength ratios significantly different from the healthy norm. Strength ratios were found to be a sound predictor of symptom incidence. The deviation from the normal ratio demonstrates the need for solutions designed to reduce the workload on the rotator cuff musculature in order to improve health and safety. Assessment of strength ratios can be used to screen for risk of symptom development. This increases technical knowledge and augments operational safety.

JCHAS Spotlight: Bowtie Diagrams

The Editor’s Spotlight for the May / June 2017 issue of the Journal of Chemical Health and Safety is shining on:

Using bowtie methodology to support laboratory hazard identification, risk management, and incident analysis by Mary Beth Mulcahy, Chris Boylan,
Samuella Sigmann, and Ralph Stuart.

This is based on a technical program workshop which Mary Beth and Chris led at the 2016 San Diego ACS National Meeting and describes how a graphical tool for organized laboratory risk assessment and incident information can support a strong laboratory safety culture.

The abstract is:

Hazard prevention and control systems for specific laboratory processes must be readily shared between lab workers, their colleagues, and lab supervisors. In order for these control systems to be effective in a transferable and sustainable way, effective risk management communication tools must be present. These tools need to be adaptable and sustainable as research processes change in response to evolving scientific needs in discovery based laboratories.

In this manuscript, the application of a risk management tool developed in the oil and gas industry known as a ‘‘bowtie diagram’’ is assessed for application in the laboratory setting. The challenges of identifying laboratory hazards and managing associated risks as well as early experiences in adapting bowtie diagrams to the laboratory setting are described. Background information about the bowtie approach is provided and the technique illustrated using an academic laboratory research scenario. We also outline the role bowtie diagrams could play in a proactive safety culture program by facilitating hazard communication and maintaining hazard awareness across a wide spectrum of stakeholders.

 

Analysis of injury data to improve safety and training

The Editor’s Spotlight for the January / February 2017 issue of the Journal of Chemical Health and Safety is shining on:

Analysis of injury data to improve safety and training by Heather Simmons, Betsy Matos and Stephen Simpson of Iowa State University.

The article describes how they used injury data to evaluate trends in laboratory-related injuries there between 2001 and 2014. As a result, they are moving away from classroom-only training and are incorporating multiple learning methods into our training program. In addition, we are utilizing near misses, narratives, and anecdotes to enhance learning.

Their new approach focuses on moving from a compliance-centered culture to one in which we use data to drive the decision-making process and our communications with researchers.
