RISK ASSESSMENT
USER MANUAL
97
RISK ASSESSMENT
is based on a clear understanding of the machine limits and func-
tions and the tasks that may be required to be performed at the machine throughout its
life.
During Risk Assessment all the
Hazards
must be
identified
and analyzed for all the pos-
sible tasks of the machine (such as maintenance or cleaning).
As an example, for a “Laser Processing Machine” the hazards list will include laser-
related hazards like:
•
Direct, scattered, diffused and indirect laser radiation
•
Fumes, particles and vapors from target material
•
Fire/explosion from target material
Refer to EN ISO 11553-1 for a complete list.
Each Hazard represent a risk of harm, and each
Risk
must be
estimated
and quantified
in terms of:
•
THE SEVERITY OF POTENTIAL INJURY
•
THE PROBABILITY OF ITS OCCURRENCE
Once the Risk Estimation is completed, next step is the Risk Reduction.
The 2006/42/EC Directive provides a
hierarchy of measures
for eliminating the risk:
1. Inherently Safe Design: Eliminate/reduce risks as far as possible by machine design
2.
Additional Protection Devices:
Install safeguarding and protective measures in
relation to risks that cannot be eliminated by design
3. Personal Protective Equipment and/or Training
In case of Protective Devices It will be necessary to ensure that access can only be
gained while the machine is safe. Protective measures such as interlocked guard doors
and/or trip systems will be required.
THERE is no ONE SINGLE SOLUTION TO SAFETY but a SYSTEMATIC PROCESS.
RISK ASSESSMENT
based on a clear understanding of the machine limits and functions
and the tasks that may be required to be performed at the machine throughout its life.
RISK REDUCTION
is then performed if necessary and safety measures are selected
based on the information derived from the risk assessment stage. The manner in which
this is done is the basis of the SAFETY STRATEGY for the machine
