SN EN 1127-1:2020
Explosionsfähige Atmosphären - Explosionsschutz - Teil 1: Grundlagen und Methodik
Explosive atmospheres - Explosion prevention and protection - Part 1: Basic concepts and methodology
This document specifies methods for the identification and assessment of hazardous situations leading to explosion and the design and construction measures appropriate for the required safety. This is achieved by: - risk assessment; - risk reduction. The safety of equipment, protective systems and components can be achieved by eliminating hazards and/or limiting the risk, i.e. by: a) appropriate design (without using safeguarding); b) safeguarding; c) information for use; d) any other preventive measures. Measures in accordance with a) (prevention) and b) (protection) against explosions are dealt with in Clause 6, measures according to c) against explosions are dealt with in Clause 7. Measures in accordance with d) are not specified in this document. They are dealt with in EN ISO 12100:2010, Clause 6. The preventive and protective measures described in this document will not provide the required level of safety unless the equipment, protective systems and components are operated within their intended use and are installed and maintained according to the relevant codes of practice or requirements. This document specifies general design and construction methods to help designers and manufacturers in achieving explosion safety in the design of equipment, protective systems and components. This document is applicable to any equipment, protective systems and components intended to be used in potentially explosive atmospheres, under atmospheric conditions. These atmospheres can arise from flammable/combustible substances processed, used or released by the equipment, protective systems and components or from materials in the vicinity of the equipment, protective systems and components and/or from the materials of construction of the equipment, protective systems and components. This document is applicable to equipment, protective systems and components at all stages of its use. This document is only applicable to equipment group II which is intended for use in other places than underground parts of mines and those parts of surface installations of such mines endangered by firedamp and/or combustible dust. This document is not applicable to: 1) medical devices intended for use in a medical environment; 2) equipment, protective systems and components where the explosion hazard results exclusively from the presence of explosive substances or unstable chemical substances; 3) equipment, protective systems and components where the explosion can occur by reaction of substances with other oxidizers than atmospheric oxygen or by other hazardous reactions or by other than atmospheric conditions; 4) equipment intended for use in domestic and non-commercial environments where potentially explosive atmospheres may only rarely be created, solely as a result of the accidental leakage of fuel gas; 5) personal protective equipment covered by Regulation (EU) 2016/425; 6) seagoing vessels and mobile offshore units together with equipment on board such vessels or units; 7) means of transport, i.e. vehicles and their trailers intended solely for transporting passengers by air or by road, rail or water networks, as well as means of transport insofar as such means are designed for transporting goods by air, by public road or rail networks or by water; vehicles intended for use in a potentially explosive atmosphere shall not be excluded; 8) the design and construction of systems containing desired, controlled combustion processes, unless they can act as ignition sources in potentially explosive atmospheres.
Why implement SN EN 1127-1:2020 now
Implementing SN EN 1127-1:2020 is increasingly vital in the Environment, Health & Safety industry due to several driving factors. Organizations face regulatory pressures to adhere to safety standards, which are often mandated by local laws or customer requirements. Additionally, businesses are pursuing internal quality goals to minimize risks associated with hazardous situations, particularly in environments with explosive atmospheres. By adopting this standard, companies can enhance their safety measures, protect their employees, and avoid costly incidents related to explosions, thus ensuring operational continuity and compliance with international safety regulations.
Prerequisites and readiness check
Before embarking on compliance with SN EN 1127-1:2020, organizations should ensure they have the following in place:
- Management commitment to support compliance initiatives.
- Resource allocation for adequate training and implementation efforts.
- Current process documentation that outlines existing safety measures.
- Risk assessment frameworks in place to identify potential hazards.
- Stakeholder engagement to ensure all parties are informed and involved.
Step 1: Gap analysis
Conducting a gap analysis is a critical first step in achieving compliance with SN EN 1127-1:2020. This process involves comparing existing safety measures and practices against the requirements outlined in the standard. Start by gathering relevant documentation, including safety policies and previous risk assessments. The analysis should include:
- Inputs: Collect data on current safety protocols and incident reports.
- Process: Evaluate the effectiveness of these protocols against SN EN 1127-1:2020 requirements.
- Outputs: Identify discrepancies and areas needing improvement. Tools such as checklists and compliance software can facilitate this analysis. Typical findings may include inadequate documentation of risk assessments or insufficient technical protective measures in place.
Step 2: Design and documentation
Once the gap analysis is complete, the next step is to document the management system in accordance with SN EN 1127-1:2020. Key components of this documentation include:
- Scope statement: Define the boundaries of the management system concerning explosion safety.
- Policy: Establish a clear safety policy that aligns with compliance objectives.
- Objectives: Set specific, measurable goals related to reducing explosion risks.
- Procedures: Document processes for risk assessment, prevention, and protection measures.
- Records: Maintain comprehensive records for audits and regulatory compliance. Each element should be tied to relevant clauses in SN EN 1127-1:2020 to ensure thorough coverage of all compliance aspects.
Step 3: Implementation and training
Implementing the new management system requires effective change management and training strategies. Begin by communicating the changes to all staff members, highlighting the importance of compliance for safety and operational efficiency. Develop targeted training sessions to ensure employees understand the new procedures and safety measures. Common pitfalls during this phase include resistance to change and inadequate training resources, which can lead to non-compliance. Addressing these challenges early on can facilitate smoother adoption of the new system.
Step 4: Internal audit and certification
The internal audit process serves as a crucial checkpoint to assess compliance with SN EN 1127-1:2020. It should be conducted periodically to ensure ongoing adherence to safety standards. The audit typically comprises two stages:
- Stage 1 (Documentation): Review all documentation and processes to confirm they align with the standard's requirements.
- Stage 2 (Implementation): Assess the actual implementation of safety measures and documentation in practice. Successful completion of these stages leads to certification, demonstrating the organization’s commitment to explosion safety.
Common pitfalls
When working towards SN EN 1127-1:2020 compliance, organizations may encounter several common pitfalls:
- Inadequate risk assessments: Regularly update assessments to reflect current conditions.
- Insufficient training: Invest in comprehensive training programs to enhance staff understanding.
- Poor documentation practices: Maintain detailed records for all procedures and audits.
- Lack of management support: Secure ongoing commitment from leadership to prioritize safety compliance.
- Failure to engage stakeholders: Involve all relevant parties early to ensure buy-in and collaboration.
