I recently attended a presentation by Dean Venturin Ph.D., Director of Health, Safety and Environmental Quality at Unifrax. You may already know that the state of California has passed an Occupational Exposure Limit for RCF (Refractory Ceramic Fiber) of 0.2 fibers per cc. This news has been convoluted by the rumor mills to mean anything from “it’s not a problem” to “they’re banning RCF”. The truth is not as simple as it sounds. The included concept of a worker lifetime principle can invite even more confusion. Dean’s presentation helped me make sense of the practical impacts of the new limit.
For clear information, I suggest you read Unifrax’s newsletter.
For additional information, including the Final Statement of Reasons, you can also see the Refractory Ceramic Fibers Coalition document.
