Poison ivy is not necessarily the culprit. A number of plants and other things can cause unpleasant reactions. PI is a very likely suspect however and I am not suggesting that you rule it out yet. Poison ivy vines or roots are often underground or under leaf cover, etc. in places where they are not so visible or obvious above ground and sometimes those parts are not so leafy and, thus, harder to notice or to identify. I have inadvertently unearthed PI roots and vines several times when weeding and digging in areas that seemed completely free of PI. Any part of the plant can give you the rash so the underground portions are certainly a problem. I've never heard of poison ivy spewing the poising into the air on its own but if it is burned the smoke is a very serious problem and is one of the many dangers for firefighters in wooded areas. Also, since any part of the plant can be trouble (even after dead) little bits and pieces of it that are not really noticeable can still cause problems. Soap and water should work for cleaning the tools. The trick is being thorough since even a tiny amount of the oil can cause the rash. I would first give a good blast of cold water to the tools before applying soap.

Unlock the tool bars (right click at the bottom right corner) Then you can move the vertical lines around on the tool bar, you can find your address bar there. I've had to do that several times, very annoying. Remember to lock the tool bar back when done.
