Precautions for Handling
Laser Safety Supervisor
⇒Appoint a safety supervisor for all laser work.
The appointed safety supervisor must have su󰀩cient knowledge and experience
regarding both lasers and laser work.
⇒The supervisor must control the keyswitch of the Laser, and must be responsible
for instructing operators in safety aspects of the Laser as well as directing the
laser work.
⇒Establish and control a laser operation area.
The responsible person must isolate the laser operation area from other areas
and control it by fences and display signs indicating that the area is o󰀨-limits to
unauthorized personnel.
⇒Install the indicating lamp etc. so that a user can recognize that the Laser is in
use from outside the laser operation area.
⇒When entering a laser operation area for maintenance etc., use the safety
interlock.
⇒When installing the output unit at a place distant from the main unit of the Laser,
enable a user to stop the laser even at a distant place.
