AIHce 2013, RT 230 Medical Marijuana in the Workplace 

Medical marijuana laws have been passed in multiple states. State law is now in direct conflict with Federal Law. What do you do when an employee tests positive for THC? How do you comply with competing laws?

AIHce 2012, RT 225 Methamphetamine Labs: Current Issues

Methamphetamine labs continue to be a public health issue. Various organizations actively conduct research on hazard identification, contamination, sampling, and cleanup strategies, however, this information does not appear to be well disseminated and available to policy makers. Following collection of evidence, industrial hygiene professionals are often called upon to perform hazard assessments and clean-up of these labs. This roundtable will address several current topics which will assist the practicing industrial hygienist to perform these tasks. NIOSH will discuss how first responders, health and remediation personnel may improve their safety and effectiveness responding to a meth lab, recognition of hazards per lab type, and selection of appropriate PPE. A research summary on dermal transfer of methamphetamine and dermal exposures from household surfaces will be presented. Methamphetamine residue testing and the selection of appropriate sampling and analysis methodology will be covered. This roundtable will also provide details on various published clearance levels within the US which highlight the variability of, and in some cases the lack of, cleanup criteria.
