Posted By John Lewis Can anyone help me out? In my current role there is a lot of polishing and linishing of Titanium and Cobalt Chrome. The polishing shops are a shambles, but I am dealing with this. What I really need to know is where can I find unbiased info' on the risks of explosion from titanium sparks entering extract filters. Historically the company has always used wet extractors to prevent the problem occurring. Recent kit has got explosion panels on it and the blasters are all earthed to prevent sparks. Any advice would be most welcome to set me on the right route. Best regards John

Posted By Kevin Irwin John, It's a while ago now but in one factory I worked in the precaution was always to use a wet filter. From memory the hazard was more from the metal fire that might occur rather than an explosion as such. Regards, Kevin
