Cobalt talked about safety in a post in the section on tools. I thought it would be a good subject for general discussion. I am sure we all have some good tip. One issuer that you do not hear a lot about is safety with found wood. Lumber we find or is given to us. We need to be sure what's in it or on it. Nails, wire, small rocks. things that can damage tools and or become missiles when using power or mallet tools. Also chemicals that may be in the wood or on it. A number of years ago I got real sick from some wood that a friend who worked on the Mobile docks gave me. We have ships from all over the world coming in to Mobile. He had some 6"x 6" X 6' mahogany that had been used as blocks to set cargo on from South America. He gave me 2 of them. I was so existed about having the wood I did not think about what it may have been sprayed with. I still do not know but ended up in the hospital the day after I started cutting it up. That night my wife as me if I had been spraying something. The point is if it comes from a barn, factory, old building or you not sure were its from and there is a chance there could be chemicals on it you may want to think twice about using it.
