NJAIHA – October ’17 Dinner Meeting

NJAIHA – October ’17 Dinner Meeting

Snuffy's Pantagis Renaissance 250 Park Avenue Scotch Plains, NJ 07076
19th October 2017

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.
