From the "Handbook of Chemical Health and Safety" Robert Alaimo, editor (http://www.oup.com/us/catalog/general/subject/Chemistry/ChemicalHealthSafet y/?view=usa&ci=9780841236707 ), Chapter 58, page 401- "Splash goggles are used at all times when using liquid cryogenics. Full-length face shield protection is required when using a wide-mouth Dewar flask and when making pressurized liquid cryogen transfers." Hope this helps. -----Original Message----- From: DCHAS-L Discussion List [mailto:DCHAS-L**At_Symbol_Here**list.uvm.edu] On Behalf Of Ralph Stuart Sent: Thursday, March 11, 2010 9:45 AM To: DCHAS-L**At_Symbol_Here**LIST.UVM.EDU Subject: [DCHAS-L] Cryogenics face shield? A lab tech writes: Do you have a recommendation for an appropriate face shield that people should be using when working with LN2? I've been searching the web and it's hard to find a specific recommendation for a face shield to be worn with cryogenics. I don't see any guidelines on OSHA that point to any particulars and nothing on the Cryogenic Society of America's site either. I would appreciate your assistance. Does anyone have any favorites they'd like to recommend? - Ralph Ralph Stuart, CIH Environmental Safety Manager University of Vermont Environmental Safety Facility 667 Spear St. Burlington, VT 05405 rstuart**At_Symbol_Here**uvm.edu fax: (802)656-5407
