[Seminarios.nanociencia] serious break of laser safety in lab B45

[reinhold.wannemacher en imdea.org]

Dear all (members of the optics groups),
today I entered the lab B45. The 355nm laser was turned on and running. 
The warning light at the entrance was turned off.
This is a serious laser safety break !!
In addition, it is an absolute waste of useful operating hours of the 
laser since it may have been running since Monday evening.
Please let us all make sure that safety measures are adhered to and that 
all lasers are turned off when they are not in use.
In the case of the 355nm laser this does not require any complcated 
procedure, neither to turn it on again, so it should
be switched off even when the one who turned it on is 15min outside of 
the lab !
Best Regards
Reinhold
