Why implement SN EN ISO 13849-2:2013 now

Implementing SN EN ISO 13849-2:2013 is crucial for organizations in the Environment, Health & Safety industry as it ensures the safety and reliability of machinery control systems. Factors such as customer requirements, regulatory pressures, and internal quality goals often drive organizations to adopt this standard. Compliance not only helps mitigate risks but also enhances the overall safety culture within the workplace, leading to improved operational efficiency and reduced liability.

Prerequisites and readiness check

Before embarking on the implementation of SN EN ISO 13849-2:2013, organizations should ensure they have the following in place:

  • Management commitment: Leadership should prioritize safety and allocate resources effectively.
  • Resource allocation: Assign dedicated personnel and budget for the implementation process.
  • Current process documentation: Review existing safety procedures and documentation for gaps.
  • Training programs: Develop or identify training resources to ensure staff are knowledgeable about safety standards.
  • Risk assessment tools: Utilize tools that align with ISO 13849-1 compliance guidelines to evaluate safety-related risks.

Step 1: Gap analysis

Conducting a gap analysis against SN EN ISO 13849-2:2013 involves several key steps. First, gather inputs such as existing safety procedures, risk assessments, and compliance documentation. Next, analyze these inputs to identify discrepancies between current practices and the requirements outlined in the standard. Common findings may include inadequate documentation, insufficient staff training, or lack of defined safety functions. Tools like safety audit checklists and risk assessment software can facilitate this process. The final output should be a report detailing the gaps identified and recommendations for remediation, ensuring alignment with ISO 13849-1 compliance requirements.

Step 2: Design and documentation

The design and documentation phase is crucial for creating a comprehensive management system that meets SN EN ISO 13849-2:2013 requirements. Key components to document include:

  • Scope statement: Define the boundaries of the safety management system, including applicable machinery and processes.
  • Policy: Establish a safety policy that aligns with organizational objectives and regulatory expectations.
  • Objectives: Set measurable safety objectives that comply with ISO 13849-1 safety performance levels.
  • Procedures: Develop standard operating procedures (SOPs) for safety-related parts of control systems (SRP/CS), ensuring clarity and accessibility.
  • Records: Maintain detailed records of safety assessments, training, and audits, which are essential for compliance verification.

Each of these components should tie back to relevant clauses in SN EN ISO 13849-2:2013, ensuring clarity and compliance.

Step 3: Implementation and training

Rolling out the safety management system requires effective change management and staff training. Organizations must communicate the importance of SN EN ISO 13849-2:2013 and its implications for daily operations. Training programs should include:

  • Overview of ISO 13849-1 functional safety standards
  • Specific requirements of SN EN ISO 13849-2:2013
  • Practical applications and case studies

Common pitfalls during this phase include insufficient training, lack of employee engagement, and resistance to change. To mitigate these issues, organizations should foster an inclusive environment where staff feel empowered to contribute to safety initiatives.

Step 4: Internal audit and certification

An internal audit is vital for assessing the effectiveness of the implemented safety management system. This audit should be scheduled regularly and structured around two main stages.

  1. Stage 1 (Documentation): Review all documentation related to SN EN ISO 13849-2:2013, ensuring compliance with ISO 13849-1 certification requirements. This includes checking policies, procedures, and records for completeness and accuracy.
  2. Stage 2 (Implementation): Evaluate the practical application of the documented system. This stage involves checking whether safety procedures are actively implemented and adhered to by staff.

Conducting these audits not only prepares organizations for external certification but also helps refine processes based on internal findings.

Common pitfalls

Implementing SN EN ISO 13849-2:2013 can be daunting. Here are some common mistakes and their solutions:

  • Ignoring employee input: Involve staff in safety discussions to improve buy-in.
  • Inadequate documentation: Ensure all processes are well-documented and regularly updated.
  • Neglecting training: Provide ongoing training to ensure all employees understand the standards and their roles.
  • Overlooking audits: Schedule regular audits to identify and address compliance gaps proactively.
  • Failing to engage management: Keep leadership informed and engaged in the safety process for better support.
