Machine safety is an integral part of production processes. The 2006/42/EC Machinery Directive requires manufacturers to conduct a comprehensive risk assessment before placing their machines on the market. In this article, we explain step by step how to conduct a risk assessment.
Risk assessment aims to identify hazards that may arise throughout the entire life cycle of the machine and to take measures to eliminate or reduce these hazards.
Risk assessment is mandatory in the following situations:
Step 1: Determining the Limits of the Machine
First, the usage limits of the machine must be clearly defined:
Step 2: Hazard Identification
Hazards that may arise throughout the entire life cycle of the machine are identified:
Step 3: Risk Estimation
The risk level is calculated for each hazard. Risk is a combination of the following factors:
Step 4: Risk Evaluation
It is evaluated whether the calculated risks are at acceptable levels. Measures must be taken for unacceptable risks.
Step 5: Risk Reduction Measures
Risks are reduced using a 3-tier method:
The PL level, which determines the reliability of safety functions, is classified from 'a' to 'e' according to EN ISO 13849-1 standard. The required PL level determined as a result of risk assessment should not be lower than the PL level of the selected safety components.
