1. Laser Reference Guides Hi I Cradle to Grave BERKELEY LAB Ken Barat CLSO LSO Workshop 2012 eee A What is this Taking a cradle to grave approach the laser safety program at LBNL has developed three laser user guides Alaser lab design guide Alaser user reference guide Alaser disposal guide The presentation will review the rationale and substance of each guide as well as the value it gives to the laser user and laser safety program As well as how to obtain free copies FREE FREE FREE FREE A Skill of the Craft is an assumption that has lead to many an accident We face a similar problem with laser users in the research setting in particular when Graduate and Post Doc students make up much of the work force The problem A All to often senior researchers and safety staff in particular Laser Safety Officers relay on knowledge we perceive our user population has Experience has shown that this population is not always as knowledgeable or lab smart as one might think They can handle it eee A The Solution he laser safety program at Lawrence Berkeley National Laboratory LBNL has developed and made available to our users three laser guides These guides present a Cradle to Grave knowledge booster or crut

5. hese guides were developed to fill a gap that the Laser Safety Program at LBNL felt needed to be filled They do not replace many existing resources but attempts to increase user awareness in a format they might use How well they accomplish this varies with and how people use them Disposal guide requires the time to apply its recommendations which salvage may not have or the room to let things sit while waiting on answers Layout guide maybe rejected by institutional facilities organizations seen as stepping on their tuff Reference Guide could be seen as a OJT guide eem i Summary he goal of the guides is to answer questions and fill in knowledge gaps f you have questions or suggestions please contact me After 9 28 at the email below lasersafetysolutions gmail com Thank you and any questions now
