ISO 14118:2017 Compliance Requirements for Machinery Safety
The compliance requirements of ISO 14118:2017 are crucial for organizations adopting SN EN ISO 14118:2018, as they ensure the safety of machinery and prevent unexpected start-ups. This guide will provide a comprehensive overview of implementing these requirements effectively.
SN EN ISO 14118:2018
Sicherheit von Maschinen - Vermeidung von unerwartetem Anlauf (ISO 14118:2017)
Safety of machinery - Prevention of unexpected start-up (ISO 14118:2017)
ISO 14118:2017 specifies requirements for designed-in means aimed at preventing unexpected machine start-up (see 3.2) to allow safe human interventions in danger zones (see Annex A). ISO 14118:2017 applies to unexpected start-up from all types of energy source, i.e.: - power supply, e.g. electrical, hydraulic, pneumatic; - stored energy due to, e.g. gravity, compressed springs; - external influences, e.g. from wind. ISO 14118:2017 does not specify performance levels or safety integrity levels for safety-related parts of control systems. While available means to prevent unexpected start-up are identified, this document does not specify the means for the prevention of unexpected machine start-up for specific machines. NOTE A type-C standard can define the required means for the prevention of harm arising from unexpected start-up. Otherwise, the requirements for a specific machine need to be determined by risk assessment outside the scope of this document.
Why implement SN EN ISO 14118:2018 now
Implementing SN EN ISO 14118:2018 is becoming increasingly vital in the Environment, Health & Safety (EHS) industry due to various business drivers. Organizations are often prompted by customer requirements, regulatory pressures, and internal quality goals to adopt safety standards that mitigate risks associated with machinery operations. Regulatory bodies, including the European Union, enforce compliance to enhance safety, making it a competitive advantage for businesses. Furthermore, the growing emphasis on workplace safety and employee welfare adds urgency, as companies strive to protect their workforce from potential hazards linked to unexpected machinery start-ups.
Prerequisites and readiness check
Before embarking on the journey to comply with SN EN ISO 14118:2018, organizations should ensure the following prerequisites are in place:
- Management commitment: Leadership must actively support and promote safety initiatives.
- Resource allocation: Adequate resources, including personnel and budget, must be allocated to implement compliance measures.
- Current process documentation: Existing processes should be documented to serve as a baseline for improvement.
- Risk assessment framework: A method for identifying and evaluating risks associated with machinery operations should be established.
Step 1: Gap analysis
Conducting a gap analysis against SN EN ISO 14118:2018 is a critical first step in the compliance process. This involves assessing the existing safety measures against the standard's requirements to identify discrepancies. Start by gathering relevant documentation, including current safety policies and procedures. The process typically involves:
- Inputs: Collect data on existing safety procedures and machinery operations.
- Process: Compare current practices with each section of the ISO standard, identifying areas of non-compliance.
- Outputs: Document findings, including gaps and proposed corrective actions. Common tools for conducting a gap analysis include checklists, audit software, and risk assessment tools. Typical findings may reveal inadequate safety interlocks or insufficient training for personnel.
Step 2: Design and documentation
Effective documentation is vital for establishing a robust management system aligned with SN EN ISO 14118:2018. This should encompass the following elements:
- Scope statement: Clearly define the boundaries of the management system, including the machinery and processes covered.
- Policy: Develop a safety policy that reflects the organization's commitment to preventing unexpected start-ups.
- Objectives: Establish measurable safety objectives in line with the compliance requirements.
- Procedures: Document processes addressing energy disconnection, risk assessments, and training protocols.
- Records: Maintain records of training, audits, and compliance checks as evidence of adherence to the standard. Each of these elements should be linked to specific clauses within SN EN ISO 14118:2018 to ensure alignment.
Step 3: Implementation and training
Rolling out the compliance system involves careful change management and staff training. It is essential to:
- Communicate changes: Clearly communicate the reasons for changes and the benefits of compliance to all employees.
- Train staff: Provide thorough training on the new procedures and safety measures to ensure understanding and adoption.
- Encourage feedback: Create an environment for employees to provide feedback on the implementation process, which can help identify areas for improvement. Common pitfalls during this phase include resistance to change, inadequate training sessions, and failure to integrate new procedures into daily operations. Address these issues proactively to enhance adoption.
Step 4: Internal audit and certification
Internal audits play a key role in verifying compliance with SN EN ISO 14118:2018. These audits should be conducted periodically to assess the effectiveness of the management system. The audit process typically includes:
- Stage 1 (Documentation): Review documentation to ensure it meets the standard's requirements and identify any gaps.
- Stage 2 (Implementation): Evaluate the implementation of procedures in practice, including staff adherence to training protocols and operational safety measures. Timely internal audits help organizations prepare for external certification audits, ensuring that all compliance measures are in place and functioning effectively.
Common pitfalls
Here are some common mistakes organizations make during compliance implementation, along with suggested fixes for each:
- Lack of management support: Foster executive buy-in through regular updates and demonstrations of safety improvements.
- Inadequate training: Implement a comprehensive training program with ongoing sessions and refresher courses.
- Neglecting documentation: Establish a systematic approach to maintain up-to-date documentation and records.
- Failure to engage staff: Involve employees in the compliance process to enhance ownership and accountability.
- Ignoring feedback: Actively seek and address feedback from staff to refine processes and procedures.
