Following best practices is crucial for ensuring compliance with SN EN ISO 14119:2025 and maintaining readiness for audits. Adhering to these guidelines not only enhances machinery safety but also mitigates risks associated with interlocking devices and guards.

Best practices at a glance

This section introduces a checklist of best practices designed to align with the clauses of SN EN ISO 14119:2025. These practices cover critical aspects of interlocking device design, selection, and implementation, ensuring that safety measures are robust and compliant with international standards.

The practices

1. Design interlocking devices according to risk assessments. Conduct thorough risk assessments to identify potential mechanical hazards associated with machinery. This practice is essential to minimize the risk of accidents and ensure compliance with Clause 5.1 of SN EN ISO 14119:2025.

2. Select interlocking devices based on functionality and environment. Choose interlocking devices that are suited to the specific application and environmental conditions. This practice aligns with Clause 6.2, which emphasizes the importance of selection criteria in achieving effective safety measures.

3. Implement key transfer systems for enhanced security. Utilize key transfer systems to prevent unauthorized access to machinery. By doing so, you can significantly reduce the risk of bypassing safety measures, as per Clause 7.3. This ensures that interlocking devices function as intended, promoting safer operations.

4. Position and fasten devices correctly. Ensure that interlocking devices are positioned and fastened in accordance with the guidelines set forth in Clause 8. Proper installation is critical for preventing accidental disengagement and maintaining the integrity of safety systems.

5. Use appropriate actuation methods. Employ actuation methods that are reliable and suitable for the application. This practice is highlighted in Clause 9, which outlines the different types of actuation mechanisms available for interlocking devices, ensuring they meet operational demands.

6. Establish guidelines to prevent bypassing. Develop and implement clear guidelines to prevent the bypassing of interlocking devices. This is vital for maintaining compliance with Clause 10 and ensuring that safety measures are adhered to, thereby protecting personnel and equipment.
