Overview
ISO/TS 12901-2:2026 is an International Organization for Standardization (ISO) technical specification that provides guidance on using a control banding approach for managing occupational risks associated with engineered nanomaterials. Specifically, it addresses nano-objects and their aggregates and agglomerates greater than 100 nm (NOAA), focusing on inhalation exposure in workplace environments. The standard is designed to offer a practical, easy-to-understand methodology for businesses, research organizations, and others involved in handling, processing, or manufacturing NOAA, especially where toxicity data and precise exposure measurements are limited or absent.
By leveraging the control banding approach, ISO/TS 12901-2 helps organizations implement systematic occupational risk management for nanotechnologies, thereby supporting worker health and safety, process compliance, and responsible innovation.
Key Topics
ISO/TS 12901-2:2026 covers the following core concepts:
- Control Banding Framework: Outlines a systematic, tiered approach to evaluating and managing workplace exposures to NOAA when information is incomplete.
- Hazard Banding: Classifies NOAA based on their physical, chemical, and toxicological profiles to assess their potential health hazards.
- Exposure Banding: Categorizes workplace scenarios by evaluating exposure potential, considering variables such as the form of NOAA, process, material amount, and dust generation.
- Risk Evaluation: Combines hazard and exposure bands to assign appropriate risk management controls, such as ventilation or containment.
- Information Gathering: Emphasizes thorough documentation and assessment of material properties, workplace conditions, and existing controls.
- Periodic Review: Establishes ongoing review and adaptation procedures to ensure controls remain effective as new information emerges or workplace practices change.
- Scope Limitation: Applies exclusively to engineered nanomaterials and does not address materials of biological origin, nor cover explosive, environmental, or transportation risks.
Applications
ISO/TS 12901-2:2026 has practical uses in a wide array of industries and settings, including:
- Manufacturing and Industrial Operations: Enables companies producing or incorporating nanomaterials into products to identify workplace risks and apply suitable exposure controls.
- Research and Development: Assists laboratories and pilot production facilities in establishing precautionary measures when toxicity data is limited.
- Occupational Health and Safety Management: Provides occupational hygienists, EHS managers, and safety officers with a structured framework for risk assessment and documentation.
- SMEs and Large Enterprises: Offers a cost-effective, pragmatic solution for small and medium-sized enterprises without in-house nano-safety specialists.
- Compliance and Reporting: Facilitates alignment with regulatory requirements for risk management of nanomaterials through systematic data gathering, documentation, and periodic control reviews.
- Worker Training and Awareness: Supports efforts to communicate risks and protective measures to employees handling nanomaterials.
