Hello friends, I've got a good question for those of you operating in Clean Rooms. We use smocks, hair nets, and face masks for contamination control during assembly. However, one style of face mask is the doctor style. It's pretty thick fabric with elastic that goes over the ears. If you cover your mouth and nose, your glasses fog, or some people develop a fear of tight spaces. Most people avoid covering the nose to prevent that, but keep the mouth covered. There lies the risk of contamination to open packages. Or, is it much of a risk? How many of you require the nose to be covered with the face mask? Thanks for your input, Glenn --------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8e To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 -----------------------------------------------------
