Subject Matter Experts

From our core business of providing scientific solutions to our clients, we have developed innovative products. Some are produced internally, and some have arisen from partnerships with other research organizations. 

For example, we build lab software solutions to help manage and streamline your labs data, and environmental testing products for a variety of applications. 

  • IntelliSEM is a powerful automated particle analysis system.
  • ParticleID is  a customizable cloud hosted web application used to identify foreign particulate matter and  assist with root cause investigations. 

Other products we create count particles and help keep the air and environment safe.

RJ Lee Group is a materials analysis laboratory and consulting company which serves many different industries. We offer scientific solutions such as industrial forensics services, laboratory and testing services, litigation support, and laboratory software to many industries:

Join us on June 3rd for the ASSE Professional Development Conference & Exposition at the Henry B. Gonzalez Convention Center in San Antonio, Texas. Stop by booth #2065 to learn more about our Industrial Hygiene and Environmental Health & Safety capabilities.

On June 6th, Don Ewert, consulting Occupational Health specialist with RJ Lee Group, will be giving a presentation titled “Crystalline Silica; Using Science to Simplify the Rules.” A brief description of the presentation can be found below:

Abstract: “While the regulated community is familiar with OSHA’s new standard limiting occupational exposure to crystalline silica, not everyone is aware of the fact that this rule follows closely behind HazCom 2012 which regulates Respirable Crystalline Silica (RCS) in bulk materials as well. Having adopted the Globally Harmonized System of Classification and Labeling (GHS-2015), OSHA now limits RCS in products to a level of 0.1% by weight. Should the actual amount exceed this value, hazard warnings and control measures must be used. Where materials are shown to contain <0.1% w/w RCS, however, they are exempt from these regulations and control measures can be waived.”

This presentation provides participants with an overview of crystalline silica and the many nuances involved with this science. Starting with raw earthen material, the author will describe mineralogical characterization and the methods used to determine RCS weight percent. There will also be a discussion of mineralogical polymorphs and a summary of the various techniques for quantitation. Finally, attendees will explore the allowances which exist under both GHS and HazCom 2012 regulations to exempt their bulk materials from unnecessary hazard classification and engineering controls.

The second half of this presentation offers an overview of exposure sampling techniques and the analytical methods used to quantify RCS. This discussion includes a historical overview of aerosol collection practices and a description of leading edge sampling techniques. These materials will also compare and contrast the different filter preparation regimen specified by OSHA and offer participants a review of how the science, as described, can help to quantify the exposures which occur. Finally, audience members will acquire a better understanding of the protocols used for silica air sampling and analysis while also gaining insight into whether the data they receive is both accurate and reliable.
