+1 To all the safety tip.
Also I would like to add that you should always wear protective gloves while working on your bike. Hand gloves will save you from hand burn from handling tools, painful pressure cones, occasional cuts and many such problems which are usually seen after handling tools. Gloves don't have to be high grade ones, simple masons gloves with cottons/fabric back and rubber/silicon grip in the front will do. These type of gloves are not that costly at all, 1 pair will last pretty long time and are comfy enough to be used even in boiling heat of summer. Trust me it will save you a lot of hand burn form wrenching and hammering.
