Concrete is the most widely used construction material in the world. The durability of concrete may be described as “the ability of concrete to resist weathering action, chemical attack, and abrasion while maintaining its desired engineering properties” (PCA). The durability of concrete is influenced by a number of factors including design, materials, mixture, placement and exposure. This Webinar will discuss the role of aggregate selection and quality, with particular focus on the chemical reactions, alkali aggregate reactions and pyrrhotite oxidation. The presenter will discuss the existing test methods and guidance documents for evaluating aggregate sources, and the challenges involved. She will also discuss recommendations for testing, monitoring, and documentation.
Using Science To Determine GHS and HazCom Classifications
Employing scientifically validated methods for toxicological characterization, this discussion details a host of internationally accepted techniques used to achieve Hazard Inversion. This highly regarded presentation intermingles GHS classification exemptions with a real-world example of the hazard reclassification process. In addition to engaging audience members to reconsider their own As-Presented product scenarios, participants will be provided with a recent case study and real-world example of Hazard Inversion success.
Worksite & COVID-19: Innovative Near Real-Time Mobile Testing Solution
Extraordinary steps have been taken this year to address the unprecedented impacts from COVID-19 (coronavirus). As countries start to reopen and return to normal, health experts emphasize the need for employers to update their safety and health programs. This involves various types of testing in order to protect their workforce and the public health as a whole.
Our webinar will examine various technologies used for identifying the COVID-19 virus and review the various testing alternatives, including how to best use data from each of these tests to verify your facility is safe. We will discuss pros and cons of:
- Diagnostic PCR-Based Tests
- The Antigen Test
- The Antibody Test
- How business executives, plant supervisors, HR professionals, and health and safety professionals can utilize this data
Finally, we will briefly cover surface sampling studies from leading health organizations (worksite door handles, elevators, counter tops, chairs, computers, etc.), as well as a review of new research on air sampling procedures.
Our experts will provide examples from the food and beverage processing, travel and tourism, and manufacturing industries to highlight the special challenges health, safety and medical professionals face as their employees return to work and get their operations back to “normal.” Finally, we will discuss our own mobile laboratory and it’s capabilities for onsite testing.
