1.6.5 Residual risk from uncontrolled laser beam escape
(angled laser head)
The laser head does not emit any laser radiation. However, laser radiation is
guided through the laser head.
To ensure that individuals are not harmed by the laser beam, the manufacturer
of the system / machine must take
(or provide written information on)
relevant
measures regarding the maximum permissible exposure limit for the laser
machine
(laser class 4)
. These measures must be monitored by the operator.
If it has been decided that safe operation is no longer possible, the product /
unit or machine must be switched off. The unit or the machine must be
protected against unintended use.
1.6.6 Corrosion in the water cooling circuit
To avoid any corrosion the instructions and maintenance intervals prescribed
by the machine manufacturer, laser source manufacturer or cooling unit
manufacturer must be observed.
To protect the water cooling circuit
(stainless steel)
against electro-chemical
corrosion, copper or brass connections
must not
be used. Only stainless steel
or plastic connections can be used.
Warning – Uncontrolled laser beam escape!
If the bending mirror is defective due to improper handling during operation
(mechanical or thermal shock, wrong wavelength range)
, the bending mirror cover
may be damaged, causing the laser beam to escape. This can lead to laser
radiation
(horizontal to the processing area)
in the laser machine.
Technical and organisational measures
must
be taken to ensure that personnel
is not exposed to laser radiation above the maximum permissible exposure
(MPE)
limit during normal operation.
For pure stainless steel circuits
use only
water with a conductivity value
prescribed by the laser manufacturer
.
