THE TORCHES THAT ARE ACTUALLY PROPOSED ON THE MARKET FOR UNDERWATER USE HAVE BEEN MODIFIED AND ADAPTED TO AVOID THAT RISK AND SO ONLY USE ONE OF THEM IF YOU WANT TRY THIS CUTTING PROCESS. test H2 explosivity tag:community.cdiver.net,2019-08-05:2371245:Video:237294 2019-08-05T08:49:59.669Z Papy One http://community.cdiver.net/profile/PapyOne955 <a href="http://community.cdiver.net/video/test-h2-explosivity"><br /> <img src="http://storage.ning.com/topology/rest/1.0/file/get/3407909252?profile=RESIZE_710x&amp;ss=00%3A00%3A01.000&amp;width=240&amp;height=180" width="240" height="180" alt="Thumbnail" /><br /> </a><br />Hi all,<br /> here is a little video from an experiment I made with Octo Diving a few months ago to verify if nearly pure hydrogen has an explosive (shockwave) reaction or not? <a href="http://community.cdiver.net/video/test-h2-explosivity"><br /> <img src="http://storage.ning.com/topology/rest/1.0/file/get/3407909252?profile=RESIZE_710x&amp;ss=00%3A00%3A01.000&amp;width=240&amp;height=180" width="240" height="180" alt="Thumbnail" /><br /> </a><br />Hi all,<br /> here is a little video from an experiment I made with Octo Diving a few months ago to verify if nearly pure hydrogen has an explosive (shockwave) reaction or not?
