PROTECTIVE CLOTHING THAT MUST BE USED FOR ALL WORK:

• Face Shields - Must be employed when working with any potentially violent reactions or when working with glassware that is under pressure or vacuum.
• Aprons - Should be worn when working with corrosives such as strong acids or bases.
• Gloves - Must be worn when working with any chemicals or cryogens. Proper glove selection is critical. At the Safety Committee web site (http://www-safety.deas.harvard.edu) under "Safety Committee Services" can be found a listing of glove type vs. chemical. If there is any question, see Lenny Solomon or your local safety officer.

GENERAL HOUSEKEEPING RULES:

• Be respectful of other people when using shared facilities and clean up after yourself.

WASTE DISPOSAL RULES:

1. All glass should be disposed in an appropriate Broken Glass Waste Box.
2. ALL sharps (including razor blades and syringes) are considered a biohazard and must be disposed of in an appropriate Sharps Collection container.
3. Satellite Accumulation Areas (SAA) are located in rooms 531 and 513. All hazardous waste requires secondary containment and should be stored in the SAA. Do not store incompatible chemicals (i.e. acids and bases) in the same secondary containment tray.
4. All chemical waste must have a university provided Hazardous Waste Tag on it. The tag should be properly filled out with all of the information except the date when the container first has waste put into it. Writing on the container itself is not acceptable. When a waste bottle is filled, the Hazardous Waste Tag must be DATED and EH&S must be called at once for waste pick-up. The number to call is 6-3322 and is printed on the green SAA sign posted in the SAA area.

FUME HOOD USE:

1. Fume hoods are for active use only. Do not leave chemicals or other materials in the fume hoods. All chemicals and materials in fume hoods must be labeled with your name, the date, and the substance. Chemicals should be used only in the HOOD and no where else.
2. All fumes hoods must be certified once per year. If you suspect a problem with a fume hood or notice that it is overdue for inspections tell your local safety officer who will call EH&S for an inspection.

CHEMICAL STORAGE:

• NO CHEMICALS ARE TO BE USED ANYWHERE IN THE ROOM APART FROM THE FUME HOOD.

SPECIAL TRAINING REQUIRED:

1. All lab personnel who generate Hazardous Waste must have current Hazardous Waste Disposal* training which includes the initial "live" training by Cate Thomas and annual "online" refresher training which is located through http://www.uos.harvard.edu.

   * The above mentioned training is offered monthly through the DEAS Safety Committee. Contact the local safety officer for more details.

CHEMICAL SPILL CLEAN-UP PROCEDURES:

1. Small spills should be cleaned up by those in the lab. There is a Spill Kit (big yellow box) located near the elevator.
2. For large spills, clear the area of personnel and call the University Operations Center (5-5560).

OTHER RELEVANT COMMENTS:

1. Basic medical kit is near the elevator.
