Health and safety in welding and allied processes - Sampling of airborne particles and gases in the operator's breathing zone - Part 2: Sampling of gases (ISO 10882-2:2024)

This specification outlines the requirements and guidance for sampling gas and particulate matter within the breathing zone of operators during welding and related processes. It provides a standardized methodology to assess the quality of the air inhaled by personnel engaged in these activities, ensuring that exposure levels are properly evaluated against established safety criteria. The document details the technical procedures for selecting appropriate sampling equipment, defining the spatial boundaries of the breathing zone, and executing the collection of representative air samples. It covers various welding techniques and addresses the specific contaminants generated during these operations, offering a consistent approach for health and safety assessments across different industrial settings. By adhering to these protocols, organizations can systematically monitor environmental conditions in the vicinity of workers, facilitating the identification of potential hazards and supporting the implementation of effective control measures. The standard serves as a foundational reference for conducting industrial hygiene surveys and evaluating the efficacy of ventilation systems or personal protective equipment in real-world scenarios involving welding operations.
