8 Chemical Storage The Chemistry Department has decided to follow the Flinn Scientific guidelines for the storage of laboratory chemicals.

12 Chemical Waste Storage & Handling Important: we can t call it chemical waste, as that has a particular legal definition. But if it walks like a duck and quacks like a duck

13 Laboratory Chemical Waste Storage Segregation of the chemical waste stream: Aqueous heavy metals Non-halogenated organic solvents Halogenated organic solvents Small sample vials may be disposed of intact by placing compatible materials in a large ziplock bag.

14 Laboratory Chemical Waste Storage Laboratory Satellite Accumulation Areas Limit: 5 gallons of general chemical waste or 1 quart of acutely hazardous material Areas should be well marked and kept orderly

15 Laboratory Chemical Waste Handling Proper handling of ethers and other peroxide forming materials: Leaving the diethyl ether can open for last bit of ether to evaporate. Instead: Rinse last residue of ether out of can with water. Immediately deface the label to indicate container was properly handled.

16 Chemical Waste Storage & Handling Pages contain detailed instructions for Laboratory Waste Disposal- however, they cannot be practiced here at Drexel UNLESS they are made integral parts of the laboratory experiment. Flinn Scientific 2005 Catalog/Reference Manual

17 What was in that bottle? Labeling

18 Labeling All chemical containers must be labeled completely. Original manufacturers labels should not be obscured. Chemicals transferred to other containers or prepared solutions should be labeled clearly with the following information: Name of the chemical and concentration Name of the solvent (if not water) Date of preparation Course number/research lab Name (not initials) of the person preparing the solution/sample

19 For chemicals prepared for use in a research lab a research notebook and page number should replace the Course Number line in the information above. Labeling When a chemical container is emptied the original label should be either removed or defaced completely using indelible ink marker or paint. This will minimize the possibility of accidentally using the wrong material due to a labeling confusion. What really is in that bottle? DMF? Chloroform? Methanol?

20 Chemical Spills The University Safety and Health Department separates hazardous chemical spills into two categories: major and minor.

21 Major Spills Chemical Spills A major spill is a large spill that involves more than 500 gm solid or 500 ml liquid or any amount of an acutely hazardous material. An acutely hazardous material is any material that is imminently dangerous to life and health. Minor Spills A minor spill is a small spill that involves less than 500 gm solid or 500 ml liquid of non-acutely hazardous materials.

22 Chemical Spills Major Spills Evacuate the lab, call University Safety & Health to clean up the mess. Minor Spills Notify other laboratory workers, use the spill kit to clean up the mess yourself, notify Safety & Health Department to remove cleaned-up spill materials. Secondary containers (overspill containers) can be used to minimize problems in case of spills.

23 Laboratory Housekeeping Your mother doesn t work hereclean up after yourself, and make sure your students do as well. At the end of lab- make sure Each student s workstation is cleaned up All common areas are cleaned up All benches are wiped down

24 Laboratory Housekeeping How many problems can you identify in this picture?

25 Incident Procedures Know what to do BEFORE something happens!

28 Laboratory & Personal Protective Equipment Be prepared! Make sure you have- and use- your personal protective equipment. Know where the safety equipment is located in your lab.

29 Laboratory Safety Equipment

30 Personal Protective Equipment Safety glasses (or goggles) are the single most important safety device in the laboratory. Gloves- appropriate to the chemical hazard Nitrile Latex Heavy rubber gloves Lab coat

31 Online Training New online training program All employees (faculty & staff), post-doctoral associates, visiting scientists, full or part-time graduate students and undergraduates doing teaching or research in a Drexel University laboratory, or those overseeing teaching or research in a Drexel University laboratory, must complete the on-line safety training modules. You have 30 days to complete the training. Failure to complete the training will result in defenestration (or other very similarly dire consequences).
