In 2019 the EPA enacted the “Final Rule” on asbestos. The EPA maintains that the final rule will protect the public from uses of asbestos that are no longer on the market and are not covered by other laws or regulations. Products that fall into the use categories covered by the final rule cannot enter production without notification to EPA and allowing the Agency time to put any required protective measures in place. However, does this rule cover all situations where asbestos exposure is possible?

This webinar discusses how the EPA's evaluation process for the asbestos exposure rule considered only lung cancer and mesothelioma as possible harmful effects. This evaluation process excluded legacy effects from mishandling of asbestos, such as contamination at sites where old buildings containing asbestos construction materials were demolished. As safety professionals, it is important for us to know preventative measures to keep employees safe during the asbestos removal process along with the safety of the public who may be exposed to asbestos fibers.



What comes to mind when you hear the words "Agent Orange"?

If you said a herbicide containing dioxin that caused serious health effects to those exposed to it, you are correct!

Dioxins and dioxin-like compounds are a family of several hundred compounds that share similar characteristics. They are persistent organic pollutants and are considered highly toxic. Most dioxins and dioxin-like compounds are produced as by-products through several processes. Other dioxin-like compounds (some PCBs) were intentionally manufactured initially, but the production has been banned for several decades. Though more than 90% of exposure to dioxins is through food, workplace exposure also exists. Though more than 90% of exposure to dioxins is through food, workplace exposure also exists. Occupational Health and Safety professionals need to be aware of the health impacts of dioxins and how to limit exposure.



Humans have been exposed to lead since ancient times. Although lead occurs naturally, human exposure is generally not a natural occurrence. Lead was used in tools, crockery, homes, plumbing, and cosmetics long before the industrial revolution. Although lead is still useful, the twentieth-century addition of lead to gasoline and its significant effect on human health led to an awareness of the impact of chemicals on the environment and human health. As safety professionals, we need to be aware of the health impacts of handling and using lead.

This webinar takes you through the history of lead, its characteristics, lead's exposure limits, and the health effects on the human body.
