Precaution while using Microscope
Glass knives, razor blades and scalpel knives are still sharp after being used. Discard only in containers provided for that purpose, or well sealed, and labeled cardboard boxes, so cleaning personnel will no be injured. Some microscopes may have mercury lamps. Mercury is a dangerous substance and it is important to follow your manual for microscope use closely. If there is a mercury lamp explosion, the lab often needs to be evacuated and sealed until the proper department can clean up the mess.
