Laboratory Safety Rules Always wear a laboratory coat when working in the laboratory classroom. Smoking, eating and drinking in the laboratory are not permitted at any time. Keep your workspace free of all unnecessary materials. Never pipette by mouth. Use the safety pipetting devices which are provided. Throw off used pipettes in the appropriate containers. Replace caps on reagents, and solution bottles, after use. Take care of the microscope.
Label everything clearly. Make sure all burners are turned off at the end of the laboratory period. Take off your gloves on when you leave the laboratory. Wash hands thoroughly with soap and water before leaving the laboratory. Familiarize yourself with the location of safety equipment in the laboratory.

Care of the microscope Never touch the glass with your fingers. Always carry the microscope with two hands. Never turn the microscope upside down or the eyepiece could fall out. Place the microscope on a level surface. Check to make sure the battery operated built-in illuminator is working. Store the microscope with a dust cover to keep it clean. When you are finished using the microscope, switch to the lowest power objective (4x), lower the stage, switch off the power, cover the microscope with a dust cover, and return the microscope to its storage area.
