BS EN ISO 10882-1:2024 – Sampling of Airborne Particles in the Operator’s Breathing Zone

Personal Exposure Monitoring for Welding Fume and Airborne Particles

BS EN ISO 10882-1:2024 provides a recognised methodology for measuring personal exposure to airborne particles generated during welding and allied processes. The standard describes how samples should be collected within the operator’s breathing zone to obtain representative measurements of welding fume and other airborne contaminants generated by welding-related activities.

The standard supports occupational hygiene programmes, exposure-monitoring strategies and COSHH compliance activities by establishing consistent approaches to personal exposure sampling.

The document applies to:

MIG and MAG welding
TIG welding
MMA welding
Flux-cored arc welding
Plasma processes
Thermal cutting
Brazing and soldering operations
Grinding and welding-related activities
Exposure assessment of airborne welding particulates

The standard also provides references to analytical methods used to determine exposure to specific hazardous substances present within welding fumes and associated airborne particles.

This resource is relevant to:

Occupational Hygienists
Exposure Monitoring Specialists
Welding Fume Consultants
LEV Designers
P601 TExT Engineers
Health & Safety Professionals
Welding Supervisors
Fabrication Managers
COSHH Assessors
Duty Holders

LEVCentral Expert Commentary

Following the HSE’s 2019 change in enforcement expectations for welding fume, there has been increasing emphasis on demonstrating that exposure controls are genuinely effective rather than simply installed.

BS EN ISO 10882-1:2024 provides an important part of that evidence base.

Whilst LEV testing and commissioning activities help confirm engineering performance, personal exposure monitoring helps answer a different question:

Is the worker actually being protected?

The standard focuses on sampling airborne particles directly within the operator’s breathing zone. This is particularly important because welding fume concentrations can vary significantly depending upon:

Welding process
Working position
Ventilation arrangements
Hood placement
Workpiece geometry
Operator behaviour
Workplace airflow patterns

Measurements taken elsewhere in the workplace may not accurately represent what the welder is actually inhaling.

One of the strengths of the 2024 revision is its closer alignment with modern occupational hygiene practices and exposure-assessment methodologies. The document references current workplace air measurement standards and complements the exposure assessment strategies described within BS EN 689.

For LEV professionals, the standard reinforces an important principle:

Airflow measurements alone cannot confirm adequate exposure control

A system may achieve design airflow rates yet still fail to adequately capture contaminants under real operating conditions. Personal exposure monitoring therefore provides an important layer of verification when assessing control effectiveness.

The standard is particularly relevant where organisations are seeking to demonstrate compliance with COSHH, investigate welding-fume exposures or validate the performance of new extraction systems.

Key Learning Points

Exposure Must Be Measured Where the Worker Breathes

The standard focuses on sampling within the operator’s breathing zone to obtain representative exposure data.

Welding Fume Remains a Significant Health Risk

Monitoring supports assessment of exposure to hazardous airborne particles generated during welding and allied processes.

LEV Testing and Exposure Monitoring Are Complementary

Engineering performance measurements and personal exposure measurements provide different but equally valuable information.

The Standard Was Updated in 2024

BS EN ISO 10882-1:2024 supersedes the withdrawn BS EN ISO 10882-1:2011 edition.

LEVCentral Observation

The 2024 revision reinforces the growing relationship between occupational hygiene and LEV engineering.

As HSE continues to focus on occupational lung disease, organisations increasingly need evidence that exposure controls are not only installed and maintained but are also delivering effective protection to workers.

BS EN ISO 10882-1:2024 provides a recognised framework for obtaining that evidence through personal exposure monitoring.
