ISO 10882-2:2024 PDF

Overview

ISO 10882-2:2024 - Health and safety in welding and allied processes - Part 2: Sampling of gases - specifies guidance and requirements for determining personal exposure to gases and vapours generated or present during welding and allied thermal processes. It applies to a wide range of joining, cutting, surfacing and removal methods (for example: manual metal arc, MIG/MAG, TIG, plasma, oxy‑fuel, laser welding/cutting, brazing, gouging and metal spraying). The standard covers common welding‑related gases such as ozone (O3), carbon monoxide (CO), carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2) and vapours from painted or coated metals. Fuel, oxidant and shielding gases are excluded. The document recognises the influence of workplace background concentrations and includes guidance on both personal (operator breathing zone) and fixed‑point measurements.

Key technical topics and requirements

• Measurement methods: Describes applicable approaches including direct‑reading electrical instruments, detector tubes (pumped and diffusive) and indirect methods requiring laboratory analysis of pumped or diffusive samplers.
• Sampling strategy: Guidance on when to use personal sampling versus fixed‑point sampling, selection of measurement conditions, screening measurements, worst‑case and time‑weighted average (TWA) assessments for comparison with occupational exposure limits.
• Sampling equipment and set‑up: Requirements for sampler positioning in the operator’s breathing zone, sampling lines, flow rates, materials of construction, filtration and multiple sampling arrangements.
• Gas‑specific guidance: Practical sampling and measurement considerations for individual gases (e.g., ozone, CO, CO2, NO, NO2) and organic vapours-including concentration ranges and special sampling notes.
• Data handling and reporting: Recording of test data, presentation of results and example test report content to support compliance and traceability.

Practical applications and who would use this standard

ISO 10882-2:2024 is intended for professionals responsible for occupational exposure assessment and control in welding environments, including:

• Occupational hygienists and safety officers conducting exposure monitoring and risk assessments
• Welding supervisors and plant managers implementing exposure control programs
• Testing laboratories and field measurement teams performing personal and fixed‑point sampling
• Regulators specifying acceptable monitoring methods and compliance checks
• Manufacturers of sampling instruments and consumables designing products for welding applications

Use cases include baseline exposure surveys, periodic monitoring for regulatory compliance, evaluation of control measures (local exhaust ventilation, PPE), and targeted worst‑case or screening measurements.

Related standards and implementation tips

• ISO 10882 series (other parts) for related particle/gas sampling in welding.
• ISO 4063 is referenced for process classification (metal‑spraying).
• Practical tip: pair personal breathing‑zone sampling with fixed‑point background measurements to distinguish process emissions from workplace background and to support accurate exposure assessments.
