All dangers cannot be removed from a research or teaching laboratory. Life Sciences is committed to making the laboratories we use reasonably safe from the hazards they contain.  Safe laboratory practices include general lab safety rules, personal protection equipment, fume hoods, biohazard cabinets and general handling and storage of chemicals. Additional precautions may be required when working with radioactive materials, lasers, ultraviolet radiation, recombinant DNA molecules, chemical carcinogens, biohazardous agents, compressed gas cylinders and cryogenic liquids.
