Standard Operating Procedure

LOCAL SAFETY OFFICER: Pablo Londero
ROOM: Jefferson 150b (Chem Room)
P.I.: M. Prentiss

DATE: August 11, 2006

TYPE OF RESEARCH: Experimental Atomic Optics

PROTECTIVE CLOTHING THAT MUST BE USED FOR ALL WORK:

• Safety Glasses - Must be employed when working with any process that could throw off debris that would break non-safety glass.
• Face Shields - Must be worn when working with corrosives such as strong acids or bases, for instance Pirhana Solution.
• Rubber Boots - N/A
• Safety Goggles - Must be worn at all times in this room. Goggles alone are insufficient if splashing of chemicals could occur--in such a case, also wear a face shield.
• Aprons - Must be worn when working with corrosives such as strong acids or bases. When working with HF, wear the neoprene apron and arm protectors.
• Gloves - When working with HF, wear both Latex gloves and neoprene over-gloves. When working with chemicals or other materials that warrant the use of protective gloves (such as work with cryogens), proper glove selection is critical. For other specific glove type vs. chemical, see http://www-safety.deas.harvard.edu under "Safety Committee Services." If there is any question, see Lenny Solomon.
• Steel-toed Shoes - Should be worn when moving heavy objects.
• Respirators - N/A
• Laser Safety Goggles - N/A
• Other - N/A
