OFF SAFETY CONSIDERATIONS
ACCORDING TO EN ISO 13849-1:2008
MACHINE SAFETY
The European Community Directives establish that industrial machinery should not
present a risk for workers and operators. The manufacturers should retain full responsi-
bility for certifying the conformity of their machinery to the provisions of
Machine
Directive
.
The
CE mark
(
) is the only marking which guarantees that machinery conforms to
the requirements of the Machine Directive.
The Machinery Directive 2006/42/EC compels machine manufacturers to meet a
mini-
mum set of requirements
before a machine may be placed on the market, Annex I, of
such directive, provides a
list of Safety Requirements
to which machinery must comply
where relevant.
It is the responsibility of the final machine manufacturer to ensure that all the Safety
Requirements are satisfied.
Several harmonized Standards have been published to support Manufacturers in Safety
Requirements fulfillment.
For Laser Processing machine:
EN 60825-1
EN ISO 11553-1
The process that brings evidence that all potential machine hazard are addressed is the
risk assessment
.
RISK ASSESSMENT
Core of the Machine Directive are “Risk Assessment” and “Risk Reduction” process.
EN ISO 12100:2010 is aimed to support manufacturers during Risk Assessment.
Machinery must be designed to be
operated, adjusted
and
maintained
without putting
persons at risk when these operations are carried out.
Risk Assessment must also taking into account any
reasonably foreseeable misuse
of
the system.
