Laser barriers



 Our laser safety people relayed the following information regarding barrier
 breakdown times to me:

 From ANSI Z136.1-1993, Appendix C (C2.4)

 "...the barrier will exhibit a threshold limit for beam penetration through
 the barrier during a specified time (typically 60 seconds)."

 Hope this helps.
