The far-reaching consequences of nonconformity and illegally CE marking can thus be avoided. Ultimately, it is in the hands of the manufacturers to live up to their responsibility and to initiate the correct measures.

The Risk assessment process:

Boundary definition

• Define the limits of the machine (EN ISO 12100-1)
• Space limits: clearance, working space etc.
• Use limits: intended use
• Time limits: probable lifetime under proper use

Hazard identification

• All conceivable hazards
• Interaction between the machine & its environment
• Possible malfunctions
• Proper use
• Requirements for personnel

Risk estimation

EN ISO 14121-1 lists four risk elements to be determined for each identified hazard, establishing the the probability of its occurrence and the severity of potential harm.

Risk evaluation

The decision whether the residual risk is acceptable or whether risk reduction measures are necessary requires experienced experts. EN ISO 12100-1 and others provide relevant guidance.

Risk reduction

The Machinery Directive provides three guiding principles to reduce residual risk: hazard elimination; technical protective measures; and user information.
