IJERPH, Vol. 13, Pages 292: Estimation of the Human Extrathoracic Deposition Fraction of Inhaled Particles Using a Polyurethane Foam Collection Substrate in an IOM Sampler

07-Mar-2016 | Sleeth, Darrah K.; Balthaser, Susan A.; Collingwood, Scott ; Larson, Rodney R., International Journal of Environmental Research and Public Health, 2016

Extrathoracic deposition of inhaled particles (i.e., in the head and throat) is an important exposure route for many hazardous materials. Current best practices for exposure assessment of aerosols in the workplace involve particle size selective sampling methods based on particle penetration into ...

Investigation of the Storage Behavior of Shredded Lithium‐Ion Batteries from Electric Vehicles for Recycling Purposes

11-Sep-2015 | Martin Grützke, Steffen Krüger, Vadim Kraft, Britta Vortmann, Sergej Rothermel, Martin Winter, Sascha Nowak, ChemSusChem, 2015

Abstract Shredding of the cells is often the first step in lithium‐ion battery (LIB) recycling. Thus, LiNi1/3Mn1/3Co1/3O2 (NMC)/graphite lithium‐ion cells from a field‐tested electric vehicle were shredded and transferred to tinplate or plastic storage containers. The formation of hazardous ...

A Fully Automated Ad‐ and Desorption Method for Resin and Solvent Screening

05-Jun-2013 | S. Schuldt, G. Schembecker, Chemical Engineering & Technology, 2013

Abstract Ad‐ and desorption are common techniques for the purification of natural substances. The main drawback is the tedious experimental procedure for resin and solvent screening. An approach of fully automated batch experiments is presented. In order to fulfill all requirements like ...

One company's near miss program–successes, learning, and improvements

01-May-2013 | Shakeel Kadri, Glen Peters, James VanOmmeren, Process Safety Progress, 2013

Process safety events (or near misses and incidents) are key indicators of a company's process safety performance. The goal in reporting and evaluating near misses is to improve operators’ hazards awareness by recognizing unsafe conditions and acting on less‐severe Tier 3 near miss events before ...

Quality problems as process safety warning signs

24-Apr-2013 | John W. Herber, Process Safety Progress, 2013

Many companies collect and report process safety incidents. Some companies also collect process safety near misses. These safety near misses are sometimes quality deviations; for example, a process parameter that exceeds the safe operating limit, a critical safety system that is activated, or a ...
