Weld fume control is not a one-off purchase; it is a managed system that must adapt to new jobs, layouts, and people. A long-term strategy blends engineering, behaviours, and measurement so exposure remains low whatever the shift brings.

Baseline, set targets, and review

Start with a walkthrough and simple particulate measurements to understand where and when fume lingers. Map tasks, dwell times, and traffic. Set practical targets such as “capture at source for all stations” and “background PM stabilised within 10 minutes after hot work.” Review quarterly and after major changes.

Engineer in layers

Use the three-layer framework: capture at source with LEV; capture in the air with air scrubbers or negative air; capture on surfaces with vacuum-only housekeeping. Select filtration suitable for fine and carcinogenic particulates—H13/H14 for room units and high-efficiency filtration on vacuums. Modular systems help you scale and reconfigure; for example, modular WFE and MAXVAC Dustblocker systems can be combined to deliver source and ambient control that moves with the line.

Maintenance and verification

• Schedule LEV thorough examination and test as required by COSHH, and record airflow under load.
• Track filter loading via pressure or flow checks; change before performance drops.
• Use a particulate monitor for quick checks after process changes and during audits.

People, procedures, and procurement

Train welders to position hoods, recognise poor capture, and report changes. Build short, visual SOPs near bays. Specify vacuum-only cleaning and ban sweeping and compressed air. In procurement, standardise on interchangeable filters and duct sizes to simplify spares and reduce downtime.

Practical takeaways

• Set baselines and measurable targets for exposure control.
• Layer source capture, ambient control, and housekeeping.
• Choose modular kit that can move with production.
• Verify with PM checks and keep COSHH records tidy.

With steady measurement, modular engineering controls, and simple routines, weld fume control becomes predictable, auditable, and easier to sustain year after year.
