FYI for those of you sharpening saw blades… We just received a notice from Creative Lakes Media regarding Cobalt-Tungsten Carbide: Sharpeners’ Health Update.
It States:”The U.S. Department of Health and Human Services release the 12th Report on Carcinogens which add Cobalt-Tungsten carbide to its revised list.
Sharpeners-Reprt.com has posted findings of the research. Our August 2013 issue (sent to paid subscribers) will feature an article about one saw shop Eide Saw and Tool, which recently updated its air filtration system. This is just one example of smart business operations featured in the newsletter.
The Material Safety Data Sheet (MSDS) for Carbide has noted for more than a decade that those who are regularly exposed to the related dust or mist need to take precautions. What is new is that permissible exposure limits in the U.S. may not adequately protect workers.”
For more information on this issue please visit the Sharpeners-Report.com. According to our sharpener, Scott Roskam, shears are not made of Cobalt-Tungsten and therefore do not pose such a hazard… but you should be cautious still about breathing in the metal dust that you are working with when sharpening.
