Goggles and aprons should be used to protect eyes and clothes. In some cases, regular goggles are not enough for contact lenses wearers. Chemicals can sometimes get in through the sides of the goggles in into the contact lenses. In the case that contacts must be worn, a style of goggles called eye cup may be worn. Sometimes it is also wise to wear gloves, depending on the tools that will be used.
Fume hoods are sometimes necessary when working with chemicals.
Well-ventilated areas should be used no matter what kind of chemicals are being used, just in case. In case of emergency in any of these cases, if chemicals are spilled, gotten in eyes, etc. Any sharp objects should be carried with the point down, and while walking. When cutting, the knife should always be pointed away from the body to avoid any unintentional injury. Basically, common sense should be used.
