Detailed Standards Coverage

SIST EN ISO 15012-4:2016 – Welding Fume Extraction and General Requirements

Health and safety in welding and allied processes – Equipment for capture and separation of welding fume – Part 4: General requirements (ISO 15012-4:2016)

Welding and allied processes can produce hazardous fumes, putting workers at significant risk. SIST EN ISO 15012-4:2016 lays down general requirements for local exhaust ventilation (LEV) systems and related equipment designed to capture and separate welding fumes before they reach the workforce.

The standard applies to both mobile and stationary extraction equipment, specifically focusing on the capture of airborne particles generated from welding activities—not gases or explosive atmospheres. It covers all aspects of design and manufacture, including hoods, ducting, filter units, air movers, and warning systems that ensure operational safety. Notably, this standard details the necessary workplace practices to maximize the effectiveness of fume capture and informs about critical hazards, while excluding electrical, mechanical, and pneumatic hazards.

Key Requirements & Specifications:

• Defines structural and operational requirements for all system components
• Outlines minimum performance, separation efficiency, and airflow requirements
• Mandates robust signaling systems for unsafe operation or insufficient extraction
• Specifies procedures for filter cleaning, waste disposal, and maintenance
• Addresses significant hazards associated with welding fume but excludes grinding dust and explosive particles

Who Needs to Comply: This standard is highly relevant for manufacturers of welding extraction equipment, welding shops, fabrication facilities, and any industrial setting where welding is a core activity. Occupational hygienists, safety officers, and maintenance personnel will find this standard indispensable.

Practical Implications: Implementing SIST EN ISO 15012-4:2016 helps organizations reduce employee exposure to hazardous fumes, comply with EU machinery directives, and demonstrate a proactive commitment to worker safety. Efficient extraction not only lowers health risks but also supports higher productivity and streamlines maintenance.

Key highlights:

• Comprehensive guidelines for welding fume extraction system design
• Focus on employee health, safety, and regulatory compliance
• Applicability to equipment manufactured after 2016, ensuring modern best practices

SIST EN ISO 45001:2023/A1:2024 – Health and Safety Management & Climate Action

Occupational health and safety management systems – Requirements with guidance for use – Amendment 1: Climate action changes (ISO 45001:2018/Amd 1:2024)

As environmental concerns grow, integrating climate action into occupational health and safety management systems is a cutting-edge imperative. This amendment to the globally recognized ISO 45001 standard ensures that organizations systematically address climate risks, opportunities, and obligations within their occupational health and safety (OH&S) frameworks.

Scope and Coverage: SIST EN ISO 45001:2023/A1:2024 extends the OH&S standard by incorporating climate action into the context of organizations, risk management, and planning. For businesses, this means assessing how climate change can impact worker safety, emergency preparedness, and the physical work environment, and embedding climate resilience into their overall health and safety strategy.

Key Requirements & Specifications:

• Mandates active consideration of climate change in identifying OH&S risks and opportunities
• Integrates climate-related objectives into OH&S policy and operational planning
• Encourages organizations to adopt proactive measures for adaptation and mitigation
• Recommends enhanced stakeholder engagement, communication, and reporting

Who Needs to Comply: Relevant for organizations of any size or sector seeking to align their OH&S management systems with modern sustainability and climate resilience requirements. Key stakeholders include health & safety managers, sustainability officers, and executive leadership teams accountable for compliance and future-proofing operations.

Practical Implications: Integrating climate action through SIST EN ISO 45001:2023/A1:2024 enables organizations to anticipate and manage new categories of risk—such as heat stress, extreme weather, and supply chain disruptions—while building trust with stakeholders and maintaining competitive advantage.

Key highlights:

• Embeds climate resilience and adaptation into OH&S management
• Advances regulatory compliance and risk management strategies
• Supports future sustainability and resilience goals

SIST EN ISO 7730:2001 – Thermal Comfort and Workplace Well-being

Moderate thermal environments – Determination of the PMV and PPD indices and specification of the conditions for thermal comfort (ISO 7730:1994)

Thermal comfort is a cornerstone of a healthy, productive work environment. SIST EN ISO 7730:2001 provides the benchmark for predicting thermal sensation and the degree of dissatisfaction (thermal discomfort) experienced by those in moderate thermal environments, such as offices, schools, and light industrial settings.

Using scientifically validated indices—the Predicted Mean Vote (PMV) and Predicted Percentage of Dissatisfied (PPD)—the standard helps organizations assess, design, and maintain indoor climates that foster comfort and optimal performance.

Key Requirements & Specifications:

• Defines methods for measuring, calculating, and evaluating PMV and PPD indices
• Sets out criteria for acceptable temperature, humidity, air velocity, and clothing insulation
• Provides guidelines for identifying and mitigating issues like draught and localized thermal discomfort
• Recommends maintaining thermal conditions to ensure comfort for at least 90% of occupants

Who Needs to Comply: The standard is aimed at employers, building designers, facility managers, occupational hygienists, and anyone responsible for optimizing indoor environmental quality.

Practical Implications: Following SIST EN ISO 7730:2001 empowers organizations to reduce absenteeism, improve cognitive performance, and increase employee satisfaction. For building planners, it informs HVAC design and monitoring to maintain high standards of comfort year-round.

Key highlights:

• Evidence-based metrics for workplace thermal comfort
• Tools to prevent discomfort, boost well-being, and support productivity
• Applicable to all moderate indoor work environments
