New OSHA standards for respirable crystalline silica (RCS) have generated quite a bit of discussion among industrial hygiene and environmental health and safety professionals. Enforcement of the new regulations began on September 23rd, 2017 for the construction industry, with a 30-day grace period so companies had ample time to implement control measures and address any potential issues. Professionals have spent months reviewing the new requirements and re-evaluating their monitoring and control plans to ensure they meet new OSHA standards for respirable crystalline silica. This will likely continue well into 2018 as the rules for general industry and maritime come into effect in June.
Smaller companies may have been compliant with the previous OSHA action levels for respirable crystalline silica, but now find themselves needing to resample and potentially implement new control measures and procedures to ensure worker safety and compliance with the new silica standards. With over 25 years of experience supporting clients’ industrial hygiene program needs, including processing thousands of respirable crystalline silica samples annually, RJ Lee Group has continued to enhance and expand our cutting edge scientific capabilities and customer support. Most notably, RJ Lee Group has achieved a 50% reduction in the detection limit for respirable crystalline silica with upgrades to our equipment and technology – an industry-leading advancement within the suite of analytical services we offer our clients to help them comply with the new OSHA silica rules.
While the standard detection limit for silica dust exposure throughout the laboratory industry is 5µg/filter, RJLG’s new equipment and technical enhancements ensures our laboratory can now report detection limits down to 2.5 µg/filter, a significant scientific step forward. More importantly, this provides a significant advantage to our customers. RJ Lee Group is now the only laboratory that can offer this enhanced analytical service for respirable crystalline silica.
The lower detection level (or level of quantitation, aka LOQ) is particularly valuable for clients that experience short duration sampling events and have a low sample volume on the filter, or for those collecting ambient (fence line) samples. At 2.5 µg/filter, RJ Lee Group offers greater precision and more meaningful results. In each of the above instances, the potential sample volume on the filter may be insufficient to allow an accurate detection with the standard 5µg/filter capabilities offered by other labs. Without an accurate figure, industrial hygienists and EH&S professionals may not have a reliable set of data upon which to base their control and containment plans and procedures silica dust exposure.
As a result of these enhancements to our analytical capabilities, RJ Lee Group continues to be a leader in the industrial hygiene, materials characterization and industrial forensics laboratory community. Our scientists, laboratory technicians, and industrial hygienists have the scientific and technical experience to support your analytical needs. Whether your project is small, large, or highly complex, we have the resources to support your project professionally, economically, and efficiently.

RJ Lee Group supports a rapidly emerging industry by providing cannabis compliance consulting services to laboratories and state agencies. Our experts determine how to successfully apply best standardized laboratory practices to a market that is still establishing its norms. RJLG’s years of experience in laboratory operations and quality management provide the proper skill sets for ensuring the success of cannabis testing labs as well as the state program that ultimately is responsible for consumer safety.
We recently performed an audit of a testing laboratory that conducts quality control (QC) testing for cannabis products. Growers and processers cannot release product directly into the market without an independent laboratory testing it to assure the safety and quality of the product. The information reviewed during the audit showed consistent inaccuracies of original raw data, as well as the information the marijuana lab reported to the client. Suspension of certification for that lab was a direct result of the RJLG audit.
An integral component of any laboratory audit is the review of the large amount of documentation any laboratory is required to produce, from standard operating procedures to final reports. In this instance, the laboratory was not able to produce approximately half of the requested documentation listed. This finding alone is enough to suspend laboratories certifications/accreditations under many different programs. As the saying goes, “If you didn’t write it down, it didn’t happen!” From the audit team’s perspective, the inability of the cannabis testing lab to produce the documents is equivalent failing to record the information, and left our auditors questioning if the information was even gathered at all. Did they take the money and actually make a report to the customer? In the worst case scenario, a lab could process more samples, yet avoid spending the time and labor costs to analyze them!
Another discovered issue was that the laboratory did not have a qualified Scientific Director on staff to review test results for a period of time which is a code requirement. However, they somehow managed to produce results for their clients during this same period. Our audit team was able to prove that results were being released to customers during this timeframe by reviewing bench sheets and comparing them to the final reporting dates.
The audit team also proved the laboratory used unacceptable lab practices by reviewing purchase orders and then comparing them to the number of tests completed. The laboratory did not purchase enough supplies to complete the number of tests that were reported.
As a result of the audit the laboratory certification was suspended. The laboratory was not able to operate until they fixed all deficiencies and went through the full certification process from beginning to end.
Auditing for cannabis compliance is a critical component to ensuring a quality product for medical and recreational consumers. For information on cannabis lab auditing services, please click below.
Don Ewert, Occupational Health Specialist at RJ Lee Group, will be presenting at the New Jersey American Hygiene Association (NJAIHA) October Dinner Meeting providing an introduction to HazCom 2012 along with a discussion of the impact GHS rules have had on hazard classification of products containing crystalline silica. Using international GHS guidelines and 1910.1200 Appendix A, the presenter will lead participants through a review of the technical methods employed in product characterization. He will also offer a discussion on exemptions which occur under GHS and provide descriptions of the techniques we use to reclassify or “hazard invert” those products containing Respirable Crystalline Silica (RCS).
The presentation has the following abstract:
“GHS Classification Shock; Scientific Approaches to Hazard Inversion”
While the regulated community is generally familiar with OSHA’s new standards limiting occupational exposure to crystalline silica, not everyone is aware of the fact that these rules follow closely behind OSHA’s HazCom 2012 regulation specifying the hazards associated with Respirable Crystalline Silica (RCS) in bulk material. Having adopted the Globally Harmonized System of Classification and Labeling (UN-GHS 2015), OSHA now limits the amount of RCS in products to 0.1 weight percent. Should concentrations exceed this value, hazard warnings and control measures must be implemented. Conversely, where materials are shown to contain <0.1% w/w RCS, they are exempt from these regulations and control/containment measures can be waived.
This presentation provides participants with an overview of GHS hazard classification techniques applicable to crystalline silica. The content also includes a description of the mineralogical polymorphs which exist and the various methods used for quantitation. Further supporting this material, the speaker will describe some of the characterization methods applicable to raw earthen materials and detail means by which the specific mineralogical properties can be used to determine RCS weight percent. Participants will also be advised of the UN-GHS and HazCom 2012 rules for hazard designation and given an overview of those exemptions we utilize to reclassify silica containing products as non-hazardous material. Finally, the lecture will look beyond crystalline silica and explore those allowances which exist under GHS and HazCom 2012 regulations to exempt a wide range of materials and chemical mixtures from unnecessary hazard classification and engineering controls.

Twenty campers and their chaperones were given a 90-minute tour of our laboratory and facilities, including the Criminal Forensics Laboratory, Concrete Services Department, Chemistry and Industrial Hygiene Laboratories, Transmission Electron Microscope (TEM) Optical Laboratories, and Information Technology department.
Representatives of each group discussed what they do for their clients and the company at large, and how our work impacts the community. The students also invited to take part in some hands-on experiences to give them a better understanding of how STEM is used in our daily tasks.
Patty Kyslinger talks to students about concrete analysis.
RJ Lee Group performs many projects that determine why concrete from bridges and roads has failed. Patty Kyslinger of the Concrete Services department demonstrated how the group analyzes concrete samples for air bubbles, using black coloring and white powder to reveal the material’s density. She also showed them how concrete is polished, then coated with epoxy dyed with fluorescent coloring to show glowing inclusions under ultraviolet light.
“I really enjoyed the day and our trip to RJ Lee Group, and loved learning all the interesting things about asbestos and concrete,” Anna Novak, a 7th grader in Burrell School District, said after the tour.
