Health and Safety in Welding and Allied Processes – Equipment for Capture and Separation of Welding Fume – Part 4: General Requirements (ISO 15012-4:2016)

The demands of modern welding processes mean protecting workers is more complex than ever, with toxic fumes presenting a serious risk during fabrication, assembly, and repair work. SIST EN ISO 15012-4:2016 provides a structured framework for the design, manufacture, and use of local exhaust ventilation (LEV) and air filtration equipment dedicated to capturing and separating welding fumes at the source.

Key Requirements and Specifications:

• Covers all components of fume extraction systems: hoods, ducting, filter units, and air movers.
• Mandates safety features like malfunctions alarms, filter cleaning mechanisms (online/offline), and safe waste handling.
• Sets out requirements for both mobile and stationary LEV equipment, ensuring adaptability for a range of workplaces.
• Does not extend to general ventilation, air conditioners, reactive/explosive dust, or grinding applications—making its scope highly focused on welding-related hazards.

Who Must Comply?

• Manufacturers of welding equipment and accessories
• Industrial facilities with welding operations (e.g., automotive, shipbuilding, structural steel fabrication)
• Maintenance teams and health & safety officers responsible for workplace air quality

Practical Implementation: Implementing this standard means not just installing compliant LEV units, but also training staff in correct use, maintenance, and recognizing warning indicators. It encourages routine airflow verification and filter changes, plus detailed instructions for system use and marking for traceability and assurance.

Notable Features:

• Presumption of conformity with EU Directive 2006/42/EC (Machinery Safety)
• Clearly defined hazard identification (see Clause 4)
• Integration with related standards for testing, marking, and airflow rates (see normative references)

Key highlights:

• Structured requirements for all fume extraction components

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

Occupational Health and Safety Management Systems – Requirements with Guidance for Use – Amendment 1: Climate Action Changes (ISO 45001:2018/Amd 1:2024)

Every employer strives for a workplace free from injury and ill-health, but the playing field is shifting. The amendment SIST EN ISO 45001:2023/A1:2024 represents a landmark step by integrating climate action considerations directly into occupational health and safety (OH&S) management systems. As climate change drives new workplace risks and scenarios, proactive organizations must adapt to remain resilient and socially responsible.

Key Requirements and Specifications:

• Supplements the core ISO 45001 framework with new obligations to assess and manage climate-related occupational health and safety risks.
• Encourages organizations to consider how climate change can influence existing and emergent hazards (e.g., extreme heat/cold, changing air quality, storm events, vector-borne diseases).
• Aligns OH&S management with broader environmental, social, and governance (ESG) goals and reporting requirements.
• Provides guidance for leadership, worker participation, and continual improvement in the context of climate action.

Who Needs to Comply?

• All organizations already certified or seeking certification to ISO 45001, across all sectors—from manufacturing and heavy industry to service providers, logistics, and office environments
• OH&S managers and cross-functional sustainability teams

Practical Implementation: To implement this amendment, organizations must update risk assessments and management plans to specifically include climate-driven health and safety scenarios. It may necessitate new monitoring systems, adjusted training, and crisis preparedness for climate-induced events. Integrating this into existing OH&S processes sharpens competitiveness, inspires stakeholder confidence, and demonstrates forward-looking responsibility.

Notable Features:

• First globally standardized link between occupational safety and climate action
• Adaptable to any organizational size or sector
• Forward-compatible with future ESG and regulatory developments

Key highlights:

• Embeds climate risk management into OH&S processes
• Supports reputation, compliance, and investor trust in sustainability
• Delivers a practical path for climate-resilient workforce protection

SIST EN ISO 7730:2001 – Moderate Thermal Environments: PMV and PPD Indices for Thermal Comfort

Moderate Thermal Environments – Determination of the PMV and PPD Indices and Specification of the Conditions for Thermal Comfort (ISO 7730:1994)

Thermal comfort in the workplace is far more than a luxury—it is a significant factor in employee satisfaction, performance, and occupational health. SIST EN ISO 7730:2001 offers a science-backed method to predict and quantify thermal comfort using the PMV (Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied) indices. These indices provide an objective base for specifying and managing acceptable thermal conditions in indoor environments.

Key Requirements and Specifications:

• Defines six key parameters for assessing thermal comfort: air temperature, mean radiant temperature, air velocity, humidity, activity (metabolic rate), and clothing insulation.
• Offers a mathematical model for predicting overall and local sensation (e.g., risk of draught discomfort).
• Specifies recommended comfort zones, helping design environments where at least 90% of occupants are satisfied (according to PMV/PPD indices).
• Applicable primarily to healthy adults in moderate indoor environments, such as offices, schools, hospitals, and light industrial settings.

Who Must Comply?

• Architects and HVAC system designers
• Facility managers and workplace health professionals
• Organizations aiming to elevate comfort, productivity, and building performance sustainability

Practical Implementation: Achieving thermal comfort starts with precise measurement of relevant variables (temperature, humidity, airflow, etc.) and adapts HVAC and building control systems to maintain conditions within recommended limits. Regular assessment with PMV/PPD calculations can be integrated into workplace quality management and environmental monitoring.

Notable Features:

• Quantitative comfort indices for evidence-based decision-making
• Facilitates compliance with occupational health standards and green building certifications
• Can be tailored for different occupant activities and clothing levels

Key highlights:

• Predicts and manages employee thermal satisfaction
• Boosts productivity by reducing comfort-related absenteeism
• Underpins design of healthy and energy-efficient environments
