What is Risk Assessment in Machinery Safety?
Risk assessment is a systematic process used to identify, evaluate, and minimize potential hazards in machinery and industrial equipment. As per ISO 12100:2010 (Safety of Machinery – General Principles for Design – Risk Assessment and Risk Reduction), manufacturers must assess and reduce risks to ensure machinery safety throughout its lifecycle. This standard helps businesses comply with CE marking requirements and other international safety regulations.
Why is Risk Assessment Important?
Risk assessment is a critical step in machinery design and operation, ensuring that machines are safe for operators, maintenance personnel, and surrounding environments. It helps manufacturers comply with safety standards, reduce workplace accidents, and avoid costly legal liabilities.
Key Steps of Risk Assessment as per ISO 12100:2010
1. Hazard Identification
Identify all potential hazards associated with the machinery, including:
✔ Mechanical hazards (e.g., moving parts, crushing, entanglement)
✔ Electrical hazards (e.g., shock, short circuits, fire risks)
✔ Thermal hazards (e.g., burns, heat exposure)
✔ Other risks (e.g., noise, vibration, ergonomic issues)
2. Risk Estimation & Evaluation
Assess the severity of harm and the probability of occurrence to determine risk levels. The factors considered include:
✔ Possible injury type and severity
✔ Frequency and duration of exposure to hazards
✔ Probability of avoiding or reducing harm
3. Risk Reduction & Safety Measures (Mitigation)
Based on the risk evaluation, implement protective measures using the Three-Step Method outlined in ISO 12100:2010:
1️Inherently Safe Design – Modify the design to eliminate hazards (e.g., enclosing moving parts).
2️Safeguarding & Protective Measures – Use safety guards, interlocks, and emergency stops.
3️User Information & Training – Provide safety instructions, warnings, and user manuals.
4. Verification & Validation
Confirm that the implemented safety measures effectively reduce risks to an acceptable level. This
includes testing, simulations, and compliance checks with relevant ISO and CE marking standards.
5. Documentation and Compliance
Maintain a detailed Risk Assessment Report as part of the Technical File, essential for CE marking compliance under the Machinery Directive 2006/42/EC. The report should include:
✔ Identified hazards and risk levels
✔ Implemented risk reduction measures
✔ Conformity assessment results
