<p>[QUOTE=&quot;krispy, post: 2078485, member: 19065&quot;]Precautions are fine. We&#039;ve discussed this material many times before, hence why I could anticipate that after advising the OP about working safely and being aware of risks in handling such materials, that there would be push back in the form of <i>tough talk</i> that downplays the precautions and risks of handling it. As we have seen, that attitude came in waves of bravado, by those who just couldn&#039;t resist the urge to indulge their egos rather than support safe practice for the OP. Thank you all for proving me right. Jim you are not one of them, but you are doing a lot to support their manner and such ilk. I would assume that as a Chemistry professor with your years of experience that you have seen the effects of some chemicals over time on people, as well as attitudes towards usage and safety change over time and I am sure you have taught or your institution requires educating your students in safe handling practice in your labs/facilities. Also, Jim, it doesn&#039;t take a college Chemistry professor to intelligently handle these materials, so throwing around your weight in that regard is unnecessary. If it were that difficult, it would require a license to obtain such materials and since they sell this stuff in Walmart and at home centers, you can see it doesn&#039;t require such advanced skills, so your credentials do little to win this argument. </p><p><br /></p><p>It&#039;s rather unfortunate that others wouldn&#039;t advise inexperienced people with taking enough precautions when they are just starting out working with this material. Like I said, they will not be such braggarts if someone goes and melts their pipes or breathes too much and becomes ill, maybe falls and hurts themselves because they took the wrong idea about using this stuff. But the onus will be on them for not taking the opportunity as I have, to underscore safe handling, respecting the potential of these materials and protecting one&#039;s self and&nbsp; property, as well as your coins.[/QUOTE]</p><p><br /></p>
